Very sharp, and nearly complete, set of Gahnite crystals. The luster is very good, and the largest crystal is 1.9 cm on edge. A truly superb specimen for the species and historic locality. It has old red ink catalogue numbering on one rear face.
This stunner is just plain sexy. It is mesmerizing in its beauty: fabulous water-clear red, superb form, and mirror-like luster round out what is likely to be as good a Spinel as you are likely to find. This crystal is nothing less than fantastic. NOTE THAT SPINEL MINING WAS ALREADY DECLINING IN MOGOK, EVEN BEFORE THE RECENT US BAN ON IMPORTS FROM BURMA
A HUGE wine-red octahedron 2.2 cm on edge with excellent luster and heft. It does have an incomplete basal pyramid and some edge wear but for what it is, and the low price, its pretty darned impressive (especially for Burma where they don't generally get so large). Two of the upper faces have an intergrown octahedron offset.
2 cm octahedron with three very sharp edges. Good to average luster and some incomplete growth, but important for its size and location.
A modified blue octahedron of value for the location. A bit worn, but interesting and cheap.
Opaque, twinned .6 cm octahedrons with fair color.

A single, highly lustrous, well formed crystal of dark purple-colored spinel, measuring 3.5 cm in length, is emplaced majestically on a crudely crystalline, white marble matrix. Admittedly, there is some very minor contact (asymmetry but not damage, rather due to growth contact) to the termination, but the form, size and luster overcome that small flaw at this price and it is a rare matrix spinel of this style, for the district. From the Burma collection of "Burma Bill" Larson, who has for decades brought out gems and then minerals as this region opened up to the trade in specimens.
A huge spinel cluster, solid and 100% spinel! The large crystal, at 4 cm across, is simply the largest spinel I have personally yet seen from Tanzania. Although not gemmy, thisis certainly an important specimen for the region.
ex. Irv Brown
Without question, this vivid red, gemmy, octahedron of spinel on white calcite, is a world class competition thumbnail. Most Mogok spinels are simply loose singles, off matrix. This one, carefully excavated from a miniature at Bill Larson's lab by Irv, is unrepaired and remains on matrix due to the careful prep work. You almost never see this quality of crystal , aside from the additional aesthetics of it being on matrix! The well formed , complete crystal measures .8 cm across. It is truly a thing of beauty.
Spinel has traditionally been an underappreciated gemstone, although its durability makes it suitable for all jewelry uses and its beauty rivals almost any gem species. This large, brilliant-cut oval beautifully proves the point. This superb stone is top grade in color, cut and internal clarity. It has totally even color saturation. It has unbelievable visual impact in person. This is an exquisite connoisseur stone of the finest quality. Highly recommended for the sophisticated collector for all three of the reasons folks invest to own a gem: investment, collectibility, and wearability. This stone was brought out in the early 90's and remained in a private collection until now. An old native cut was updated and perfected in a recut by Spectrum-Award winner Mark Kaufman.
Mineral collectors are familiar with red spinel, but richly colored specimens of other hues are in high demand by gem collectors as the species is both wearable and underpriced in the public market relative to their more famous colored brethren, the rubies & sapphires. This is a rare, intense blue spinel of a size (over 5 carats) to be considered investment grade. In fact, fine cut spinels often trade with a higher desirability than similarly-priced colored stones of other species, as you get more for your money with a spinel (according to Wise: Secrets of the Gem Trade - a great book you can buy on Amazon). A small fluid inclusion is useful to prove natural origins, and not eye visible. This jewel is perhaps best described as a "designer stone" for a collector or use in unique jewelry. Cut by Spectrum Award winning faceter Mark Kaufman. The beautifully oval portuguese cut is both very clean and exceptionally bright, in excellent proportion. Simply put, an impressive gem of superb quality to wear or invest in.
Another unusual spinel of excellent quality that nicely complements the blue specimen above. This oval portuguese cut has a strong lavendar hue - top color for its type, if you want to classify it. There is a slight "window" to the gem, but it's both large and clean with superb clarity. Mineral collectors are familiar with red spinel, but richly colored specimens of other hues are in high demand by gem collectors as the species is both wearable and underpriced in the public market relative to their more famous colored brethren, the rubies & sapphires.

Accoprding to his book's recommendations, this is a rare fancy colored spinel of a size (over 5 carats) to be considered investment grade.
Spinel comes in a variety of colors and this particular stone falls into what is sometimes marketed as "Titanium Spinel". The color is almost metallic, and most Spinels actually have more a metallic appearance than most stones in my mind. The stone has what I would call a silvery overtone, but it appears to have a very slight lilac color as well. The gem is nearly eye clean with a "Step Cushion" cut.
Spinel is gem that comes in a great range of colors. Most people are familiar with the Ruby Spinels, but a large percentage of Spinels out there are not red. The vast majority of the gem Spinels in the world are found in southeast Asia, but some really impressive Spinels have been coming out of Tanzania in recent years. This particular stone is an attractive, good sized, very very slightly included, bright purplish pink color, "Oval" cut gem. It has a very attractive color and the size of the stone in this clarity is really impressive. It is difficult to find superb quality Spinels, espeically in this size from Tanzania.
