Hexagonal ruby crystals of good size dominate this specimen. They range in size from 1/8 inch or less to about 1/2 inch long by 1/2 inch wide, and have very good crystal forms. Their color is a bit too violet for gems, and the stones are translucent at best, but the crystals are of very good quality. I'm not sure, but I believe that among the constituents of the Syenite matrix rest tiny, misshapen Garnet crystals.

Penshere, Northwestern Frontier Province, Pakistan

These Pakistani crystals are some of the best rough Rubies that I've ever held in my hands. They have a bright, pigeon's-blood color that is easily worthy of a cut stone. The crystals are small, measuring about 3/8 inch at their widest points, and translucent, showing slight glimpses of transparency in areas. They show excellent crystal form, with clean sides and edges. There are a few other, tiny crystals in the Pegmatite matrix, along with a small complement of Muscovite. This is my favorite Ruby specimen, for obvious reasons! They glow VERY brightly under a longwave UV source, though our image of this occurrence is not a good one.

While the crystals on this specimen are not perfect, their deep red color makes them a very pretty addition to any collection. The largest ruby measures about 1/2 inch by 1/2 inch by 3/8 inch and shows considerable damage. The color of the crystals are quite deep, and each one is translucent- the largest is so large and dark as to be almost opaque. I really like the color of these crystals, though; they look great against the black and white background of the Syenite matrix.

One of the larger individual rubies that I have beheld, this specimen consists of one single crystal that exceeds 1/4 pound! It is a dark violet-red and is opaque, so it is not exactly a faceter's dream. However, such rubies may produce interesting cabochons with such effects as silk, cat's eyes, and possibly even six-rayed stars... who knows? It does show signs of weathering and inclusions of black crystals that I cannot identify. There is also substantial rust staining that seems to be connected with the presence of tiny amounts of muscovite that are trapped in the deep striations along the crystal's prism faces. It is an impressive chunk of aluminum oxide!

Hit-Ostrpv, Karelia, Kola Peninsula, Russia

This lovely thumbnail specimen contains a double-terminated Ruby crystal from the famous Kola Peninsula. It has clean termination faces and a definitely hexagonal prismatic crystal form, although its prism faces are heavily marred by nepheline and garnet crystals that are grown into them. The syenite matrix has several other garnets embedded in it. The Ruby has a red coloration with a tinge of violet, a pearly luster and is translucent. The specimen has been glued into a plastic specimen box.

This specimen consists of a tough nepheline syenite matrix that houses several deep red-violet rubies. The visible rubies are very rough and are only translucent, but there is some definite crystal form visible. The largest visible crystal shows the best form though it appears to be broken. Its visible dimensions measure 0.6 x 0.4 x 0.4" (1.5 x 1.0 x 1.0 cm). Like the others, it is translucent but very cloudy and seems to have a thin layer of matrix covering part of it. They are all partially buried in the matrix, and could use a bit of cleaning and added exposure, but they still constitute an interesting specimen that is relatively low in price with respect to our selection.

The nepheline syenite matrix of this specimen contains many Ruby crystals; though they are rather small, there are a lot of them, and probably even more trapped within. All have relatively good hexagonal prismatic form where it can be seen, though there is noticeable damage to a few of the crystals. They all have a deep red-violet color and a pearly luster, and are translucent but cloudy. I believe that there are many more Rubies that are trapped inside the matrix.

Jigdalik, Afghanistan

What appears to be a white calcite or limestone is the matrix for one of the largest and most well-formed Rubies that I have ever examined. The stone's visible dimensions measure 0.7 x 0.6 x 0.4" (1.8 x 1.5 x 1.0 cm) and it is in excellent condition, showing no human-induced damage. The part of the crystal that is still buried in the rock probably is malformed or incomplete, but what is visible has flat, relatively smooth faces and very well-defined edges that accentuate its pearly luster. It has a deep ruby-red coloration with a tiny hint of violet, and is cloudy and translucent. It glows a rather bright red under longwave UV light, but there was too much interfering "glow" from the host rock to get a good image of this. There are 4 or 5 other visible rubies trapped in the matrix, two of which show considerable damage, but none of these exceeds 0.3" (8 mm) in any dimension. There is also part of a damaged, dark-gray metallic mineral visible that I cannot identify, and a large amount of muscovite, some of which permeates the host rock in thin, parallel veins. It is a beautiful Ruby that is well-exposed and easy to examine.

A very small specimen, this piece nonetheless has a few Rubies in it. Most of the Ruby crystals are damaged and incomplete, though there is at least one that is relatively intact, though scarred. All have a bright red coloration with a faint hint of violet, and are at least translucent. The intact crystal's hexagonal prismatic form is imperfect but definable, as a few prism faces and the basal termination face are at least partially visible. It has a rather dull, pearly luster and is merely translucent, though there may be a few small spots of transparence. The surrounding host rock is definitely calcite-based, and has a milky-white coloration.

This is one of the first Ruby specimens that I have seen from the island of Madagascar. It consists of two hexagonal tabular Ruby crystals that are partly intergrown. The larger crystal has dimensions of 1.1 x 1.0 x 0.1" (2.8 x 2.5 x 0.3 cm), and is damaged and incomplete. The smaller crystal has dimensions of 0.9 x 0.7 x 0.2" (2.3 x 1.8 x 0.5 cm) and is undamaged and in excellent condition. Both crystals have good form, with relatively well-defined edges and striated but clean faces that possess a pearly luster. Their color is a deep ruby-red and they are moderately to dimly translucent under a halogen light. There are a few small bits of a dark matrix rock that are attached to its edges- these are likely made of nepheline.

At least 9 hexagonal prismatic Ruby crystals are partly embedded in the syenite matrix of this specimen. These crystals do not exceed 0.3" (8 mm) in any dimension, though most are of a similar size. Three or four of the crystals show obvious damage, and one of these is incomplete. However, those that are intact are in good condition and show very good form, with relatively well-defined edges and striated but clean faces that possess a rather dull pearly luster. All have the standard ruby-red coloration, though a few of the largest crystals are darker in color than the rest. All are moderately to dimly translucent. Their syenite matrix contains many more visible rubies, but most of these are broken and measure no more than 2 or 3 mm in any dimension.

This large thumbnail specimen consists of at least 15 Ruby crystals that are partly embedded in a syenite host rock. The largest crystal has visible dimensions of 0.6 x 0.4 x 0.1 (1.5 x 1.0 x 0.3 cm). They are generally in good condition, though several are obviously damaged. All have reasonably good but somewhat warped hexagonal form, but their edges are generally well-defined. Their faces are striated but clean and possess a rather dull pearly-to-waxy luster. All have the deep red coloration that is a hallmark of Rubies, and all are translucent and cloudy.

Two hexagonal Ruby crystals and several tiny, broken ones inhabit the syenite host rock of this specimen. One is damaged and missing some material, but the other is undamaged and has dimensions of 0.5 x 0.2 x 0.2" (1.3 x 0.5 x 0.5 cm), though it is not quite complete- one end appears to have partly intergrown with either the host rock or another crystal. The termination on that end is uneven, though it is natural. Both show reasonably good hexagonal prismatic form, with relatively well-defined edges and clean faces that possess a pearly luster. Both of the crystals have the standard deep ruby-red coloration and are dimly translucent. All other Rubies that are visible on the host rock are broken, incomplete, and do not exceed 3 mm in any dimension.

This small hand specimen consists of a partly-cut section of rough Ruby-zoisite. It consists of several Ruby crystals that are embedded in a green zoisite matrix. Every Ruby that is visible is damaged or broken, and shows no crystal form. All have a deep red coloration and possess a pearly luster. It is impossible to determine their clarity, though I am relatively certain that they are merely translucent, and possibly dimly so. The zoisite has a beautiful green coloration and contains many small black crystals of a mineral that I cannot identify. Besides this matrix, there is no host or base rock present.

Of the 5 discernable Ruby crystals that are visible on this specimen, only 2 are complete and undamaged- the others are broken and incomplete. These two intact crystals are in excellent condition, however. The larger of the two has visible dimensions of 0.5 x 0.4 x 0.2" (1.3 x 1.0 x 0.5 cm), whereas the smaller measures 0.2 x 0.1 x 0.1" (5 x 3 x 2 mm). Both have rather warped but good hexagonal prismatic form, with well-defined edges and clean faces that possess a slightly dull vitreous luster. Their color is a bright red that borders on a deep pink, and though the larger crystal appears to be completely cloudy, the smaller one has dim but noticeable transparence. The largest of the incomplete crystals (and the second largest overall) appears to be partly healed. They are accompanied by several tiny, misshapen "books" of muscovite that are also embedded in the white albite host rock.

This small thumbnail specimen consists of at least 4 Ruby crystals that are partly embedded in a white pegmatite host rock. The rubies are in basically good condition, showing a few small chips out of some edges, and do not exceed 0.3" (8 mm) along any axis. Their hexagonal prismatic form is badly warped due to intergrowth and other conditions, but one crystal is somewhat well-formed. They do have well-defined edges, though, and a few clean faces that possess a dull pearly-to-waxy luster. Their color is excellent, being a moderately deep red with a hint of blue, and all are translucent-to-transparent, with one crystal showing some dim but noticeable clarity. One Ruby crystal does not appear to be intergrown with the rest, and is almost completely obscured by the surrounding pegmatite. Only a few bits of muscovite accompany the crystals.

Two intergrown Ruby crystals make up this thumbnail specimen. One is much larger than the other- its dimensions make up those of the entire specimen- and is complete, whereas the smaller crystal is damaged, incomplete, and mostly intergrown with the larger one. Both have good but slightly warped hexagonal prismatic form with flat, basal terminations; the larger crystal is double-terminated. Their edges are well-defined, but their faces are heavily patterned by small growth projections. Their deep red color with a hint of violet is standard for pieces from this locality, and only the small crystal shows noticeable translucence. There is no host rock present.

A single hexagonal Ruby crystal extends from the pegmatite base of this thumbnail specimen. This Ruby has visible dimensions of 0.3 x 0.2 x 0.1" (8 x 6 x 3 mm), and is in excellent condition, showing no visible damage. Its hexagonal prismatic form is slightly warped- though its hexagonal outline is still well-defined, the prism is bent just beneath its termination. It still has well-defined edges and clean faces, however, and possess the classic deep red color with a hint of violet. Its luster is a rather dull pearly, and it is generally translucent with patches of dim transparence. It also glows brightly with a red color when viewed under longwave ultraviolet light, as seen in our second image.

This large thumbnail specimen consists entirely of 2 Ruby crystals. The larger of these crystals is complete and in moderately good condition, and has dimensions of the piece as a whole. The other does not exceed 0.5" (1.3 cm) in either length or diameter and is mostly intergrown with the larger. Both are fairly well-formed but obviously warped to a degree. Their hexagonal prismatic form is still discernable, though their edges are generally rounded and uneven, and their faces are heavily patterned and pitted. Both crystals have a deep red coloration with a strong violet hint and a very dull, almost matte luster, and are opaque to all intents and purposes. There a few crystals or pebbles of a black material embedded in the larger Ruby, but no host rock is present.

This flat piece consists of a cut, polished slab of zoisite matrix that holds several Rubies. These Rubies are rather heavily intergrown with each other and do not exceed 0.4" (1.0 cm) in diameter. Their intergrowth and the fact that they have been cut flat makes it almost impossible to study their form, and all but one are only visible on one side of the piece. They have a deep red coloration with a strong hint of violet and even when polished, tend to show only a rather bright, greasy luster. Most of the Rubies are immediately surrounded by a white material that is also embedded in the zoisite, and tiny green crystals (of zoisite, perhaps?) are visble in most of this material.

This specimen essentially consists of a single large ruby crystal on an impure marble matrix. The ruby crystal, measuring at least 0.88 by 0.38 by 0.30" (22 by 11 by 7mm), has the classic deep ruby-red color and a vitreous luster. It is partially terminated, showing proper crystal form on one side, and the other side is where the specimen was broken from its host rock. The fractured side does sparkle and show some transparency, although the bulk of the crystal is merely translucent due to many internal fractures and inclusions. A close inspection with a 15x loupe reveals many "surprise" minerals on the matrix, with unidentified green specs, mory tiny rubies, and a vein of chalcopyrite on the bottom close to a tiny pink crystal (not likely more ruby) in a protected cavity.

This hand specimen is a chunk of zoisite crystals with a dozen exposed rubies, one of which is very nice (front image). It is a flattened pink translucent crystal, measuring 13mm in width, with some damage around the edges and a good luster. All of the ruby crystals appear to be flat, generally no more than a single millimeter thick, even though the largest crystal measures 17mm in width. Most of the exposed ruby crystals are rather pale and on the reverse side, and some are only visible edge-on (see back image). This is a very nice specimen, between the contrasting colors and textures, and the large crystal of ruby and especially the large zoisite amphibolite crystals.

To the naked eye, this ruby specimen is not very exciting. It does have a two dozen ruby crystals in a gray host rock, and the ruby crystals are a dark red and at least some of them are well-formed. They are only slightly translucent, and, for the most part, they have a dull luster. However, under long-wave ultraviolet, the ruby crystals glow with a bright laser-red glow (the first laser was a ruby laser, back in 1957). The fluorescent image does not do justice to these rubies, as they look a bright deep red under long wave ultraviolet.

This is a very nice hand specimen consisting of a single large ruby crystal. It has a pinkish-red color with a hint of purple (some would call the color "maroon"). It is only dimly translucent, and while the crystal is nearly complete with a hexagonal cross section and a basal termination, it is somewhat distorted with a barrel shape and a stepped growth pattern towards the top. It also has a nice heft, showing the density of ruby quite nicely.

This ruby crystal is a deep maroon color, and is somewhat translucent (some thin edges appear almost transparent). The crystal is an elongated hexagon with flat terminations. The sides have diagonal striations (criss-crossed on one face). Now for the oddity - on one side and barely visible to the naked eye (easily seen with a loupe) is a single hexagonal crystal of something that reflects a bright green. It's color may be due to an interference effect, as it appears quite monochromatic. I wonder what it is.

This ruby is quite nice. It is a stubby hexagonal crystal, with a deep ruby-red color, a vitreous luster and good transparency. The sides display a layered pattern, whether due to a layered growth or basal parting, I do not know. The termination is flat but slightly concave, and the cross section is a nearly perfect hexagon. There is a bit of the host rock attached, it is colorless transparent tiny crystals (it looks a lot like diopside), with black inclusions. There is another interesting inclusion - a loupe reveals a tiny triangular black inclusion embedded in the top of the ruby.

Mysore, India

A dozen ruby crystals are exposed in this host rock of mica and quartz. A few of the crystals are fairly nice, with enough of the crystal exposed to reveal a hexagonal, prismatic shape with tapering sides. Their color is more of a deep pink than a ruby red, and they are translucent. Under a long-wave ultraviolet light, however, they really shine. All of the rubies fluoresce a bright, perfect ruby red, the same color as the first laser (which was made from an artificial ruby).
