Tsavorite Garnet from Merelani Mine, Arusha, Tanzania [db_pics/new2010/Tsav5.jpg]

This is one exceptional gem and another of our favorites in the size range! A gorgeous and extremely bright, neon-green round. Round cuts are in high demand for their exquisite symmetry and ability to fit into any type of jewelry. The color and cut look phenomenal in even lower lighting conditions. However on close inspection, this stone has unusual whitish striations inside that show with the camera. 0.9 x 0.5 cm. 2.92 carats.. $1000/ct

This is a bright stone of a saturated, deep green color. What makes it so special is the unusual but quite attractive and rarely seen marquise style cut. The stone’s proper proportions make it lively and a standout. The only marquise cut available at this time in our lot. SUPERB QUALITY and a lot of PRESENCE for the size!.1.1 x 1.4 x 0.5 cm. 2.89 carats. $1900/ct

Tsavorite Garnet from Merelani Mine, Arusha, Tanzania [db_pics/new2010/Tsav7.jpg]

One the most important, investment-grade stones in the lot. Tremendous eye appeal due to the exceptionally bright trilliant (“triangular brilliant”) cut and lovely, even color of a high intensity. It also represents a superb value for the size and quality because stones at or over 4 carats are hard to come by in this quality. Stunning in a jewelry setting, this is also one of teh best cut trilliants our source has had in years. 1.3 cm across, and 4.8 carats. $2000/ct

One the “flashiest” stones in the lot. Tremendous eye appeal due to the exceptionally bright trilliant (“triangular brilliant”) cut and lovely, even color. It also represents a superb value for the size and quality. Another stone well suited for jewelry or just display. 1 x 1 x 0.6 thanks, 2.10 carats. $1500/ct

Tsavorite Garnet from Merelani Mine, Arusha, Tanzania [db_pics/new2010/Tsav9.jpg]

Arguably the most impressive and important stone of the lot -- an absolutely beautiful gem with unbelievable presence in person. The neon-green color is evenly saturated and appears deepened by the excellent oval cut. Not too dark (though dark is technically good in investment tsavorites!) and not too light (which some people prefer for jewelry uses), we can only describe this stone as a “screamer.” A significant stone: This is a superb display specimen of excellent size and would make an incredible piece of jewelry. Irreplaceable at this price from our source, and a tremendous value for the price. 1.1 x 1.2 x 1.2 cm. 6.24 carats . $1600/ct. Stone sof this quality and size are exceedingly rare on the market now

A sharp, complete-all-around 1.3 cm crystal of unusually good Hessonite for this region. Garnet in orange hues seems to be actually quite rare here, and this is a very nice thumbnail example.

Stunning, gem orange spessartine-colored crystal measuring 1.6 cm across, perched with smaller crystals on a bit of quartz - overall a KILLER thumbnail! Wayne had never cleaned this. It still has pocket clay attached, as you can see, and which I have left on for contrast.

This specimen hosts the fattest and juiciest crystal of the lot, a 1.6 cm hessonite, perched on matrix. VERY good garnet thumb from any locale, but especially for this find.

Grossular Garnet (rare pink color) from Jeffrey Mine, Asbestos, Richmond Co., Quebec, Canada [db_pics/new2010/tuc1002c.jpg]

PINK garnet is extremely uncommon and pink grossulars, from the Jeffrey Mine, have been found in only a very few small pockets over many decades of mining there (and the quarry is now defunct, so there will ot be more). They have been priced like gold from the miners, with even small reference samples with 1-3 mm bashed crystals, selling for several hundred dollars. This is a large, rich plate of the material, and is an exceptional specimen of very high quality, which I sold to a collector back in the late 1990s when these came out (and recently bought back). It has crystals to just under 1 cm, and they are absolutely gemmy-clean, and sparkling with lustre. There is only a very trivial amount of damage, to the periphery where the piece contacted others: inevitable and acceptable as these were all chopped off the walls as thin, adjacent, plates. This is the best one I have had back for sale in about a decade, and I regard it highly. Lastly, there were varying shades of pink color. This has the absolute richest color you could have gotten at the time , very intense. The price may seem expensive, and no question it is expensive, compared to other Jeffrey garnet styles and colors. But, it has been this way since they came out, and again this is, I think, one of the better ones

From the now-defunct Jeffrey Mine, this is a major garnet specimen with top color, riveting lustre, and huge gemmy crystals to 2.1 cm across. The color is fantastic, really top rate, and the gemminess is such that you can see through ALL crystals to their cores and the small bit of underlaying matrix. The crystals cover a thin matrix plate. The display face is totally pristine and complete, and the only damage is simply the peripheral attachments around the rim of the piece. With garnet from this classic locale evaporating from the market, now that the mines are closed, I am tempted to simply stash this for the future as good specimens from here should prove a very good investment, as far as minerals go.

This is a true rarity, the likes of which I had never seen or heard of before for the locale: PURPLE prehnite crystals, supposedly colored by the same agent (manganese) that also makes vesuvianite from here go purple occasionally. The crystals have a definite lavender color in person, and are perched on a plate of minutely crystallized grossular garnet matrix. At the edge of the plate, brilliant, deep green garnets to 2 or 3mm form a sparkling contrast to the prehnites. These sharply crystallized prehnites, to 3 cm long and tapered like chisels, are exceptional for the species and locality. And, they seem quite unique. This specimen is from the collection of Franco Spertini, the mine geologist during the heyday of this operation (now, sadly, defunct and closed). As a side note, we purchased a number of the specimens from this collection for a future update on this site...but there is no other like this.

Maryland produces so few mineral specimens, I never expected to be holding a garnet from here. I had once read about them (MR vol 17 #2, pages 127-128) but never seen one for sale. This piece features a VERY intensely colored, wine-red garnet crystal of 2.3 cm, which is mostly complete but just has a small impact fracture on the lower periphery, and two shallow scratches or contacts atop one face. A nice accent is the super-sharp and geometric 1 cm crystal perched above. From the extensive garnet collection of David Bristol.Joe Budd Photo
