Allanite from Brazil [db_pics/new09/rlkg024b.JPG]Allanite from Brazil [db_pics/new09/rlkg024c.JPG]

Allanite is a member of the Epidote group and is one of the rare cut stones from this group i.e., Epidote, Clinozoisite, Zoisite, etc. Allanite is the only member of this group that contains the rare earth elements Yttrium and Lanthanum. This stone is essentially opaque, with a very very dark brown (virtually black) color and an Elongated Rectangle cut. It's a great rare gem to add to a "black stone" collection, or to fill out one of the spots in the Epidote group in your collection.


GEMS-017 - Bastnasite - SOLD

Within the last few years, the locality at Zagi Mountain in Pakistan has provided collectors with some of the finest quality and amazingly gemmy Bastnäsite specimens. Typically the species forms in relatively thin blades and was never suitable enough for cutting stones. The new find in Pakistan has produced some very thick crystals for the species, many of which are of gem quality. The stones cut from some of these crystals are extremely rare and highly prized by collectors. They often have some sort of inclusions, and completely eye clean gems are very hard to find. This particular stone is a beautiful, golden orange color gem with a Marquise cut. The stone is only very very slightly included, which is quite impressive for a stone this size. This stone would fill a spot in any rare gem collection, and it appears that the locality might be dwindling as less and less Bastnäsite comes out each year.

Beryl is a favorite among collectors and dealers because of the broad spectrum of colors and the ability to obtain large clean gems. Aquamarine is one of the most popular varieties of Beryl on the market today. This particular gem is a beautiful, natural blue color, virtually eye clean Aquamarine stone from the Mozambique gem fields. The stone has a very fine Trillion cut as well. Gem quality Aquamarines are becoming more and more difficult to find, and the price seems to be rising throughout the gem trade. Please note that this gem has not been heated, and the color is very good for a natural Aqua.


GEMS-010 - Rhodonite - SOLD
Morro da Mina mine, Brazil

Rhodonite is rarely found in large enough gem sections to facet stones, and despite is simplistic chemistry, it is a relatively rare mineral. The only gem quality Rhodonite that I've seen is from the Morro da Mina mine in Brazil. These stones are rarely eye clean, but they are gem quality Rhodonite and very well known among rare gem collectors. This particular stone has a few slight inclusions, but the color is a pleasing pink (very similar to smaller Sweet Home Rhodos). The cut on the stone is a Freeform cut. There's truly only one mine where you can get gems of this material in the world. I must say that since the stone is somewhat small it was not the easiest gem to photograph, and it does look very nice in person, even though the photos are a bit fuzzy. Nonetheless, it is a beautiful rare gem to add to a rare stone collection. Keep in mind that not all Rhodonite is pink, as there are localities that produce dark brown Rhodonite which is not nearly as attractive as this material.

Zircon (multi-stone set) from Vietnam [db_pics/new09/rlkg001d.JPG]

Zircons are one of the most diverse gems when it comes to color. Vietnam has only recently made a significant impact on the world gem trade producing some very fine Rubies along with some very fine Zircons. Typically one associates Zircon gems with the color blue, but Zircon occurs in virtually every color of the rainbow. This set features 14 individual eye clean gems of varying hues, all from Vietnam. The colors range from blue to yellow to orange to red, with shades of pink and copper in other stones. No two stones are exactly the same color, and assembling matching sets of stones like this is not an easy task, especially since all the stones have the same style of round cut, so they match perfectly.

This is another super rare collector's stone. When is the last time that you can remember seeing a faceted stone of Aragonite? This mineral rarely comes in facet grade material, especially in gems this size. It's a superb, very very slightly included well cut gem with an Elongated Octagonal cut. These gems are very difficult to find these days as I’m told that the locality that produced these stones is long defunct.


GEMS-071 - Natrolite - SOLD
Bound Brook Quarry, New Jersey, USA

This gem is an exceptionally rare, rather large, virtually eye clean, hard to find, collector's stone. The stone has a Pyramid Table Emerald cut, and is very bright for this material. Natrolite is one of the very few facettable Zeolites in the world. This stone is from slightly older mining at Bound Brook, New Jersey. If you're a serious gem collector, you need one of these in your collection. Especially if you like to collect gems from North America, or simply from the United States. There is very little of this material available on the market, and the stones from Bound Brook are for all intents and purposes, the finest facetted Natrolites in the world, so do not miss out on this one.


GEMS-067 - Jeremejevite - SOLD

Jeremejevite is a very rare borate, and one of the most highly sought after mineral species in the world. Cut stones of Jeremejevite are virtually impossible to find on the market these days, and the top stones are highly prized by collectors. This stone is from the historic Mile 72 locality in the Swakopmund District of Namibia, and is the premier locality for Jeremejevite in the world. This is a very good sized stone of this material, as most Jeremejevite gems are under 1 carat, and this gem is over 1 carat. With that said, the color in this gem is a good medium blue (there is a slight purple overtone that is not showing up in the photos), and not at all grey, yellow or colorless like many Jeremejevite gems from this area. The stone has a Barion cut and is very attractive for the material with very slight inclusions. You do not see Jeremejevite gems on the market today, and the majority of the best crystals are stashed away in old collections and museums. A great opportunity to own a fine quality, colorful collector gem from a premier locality.

Beryl comes in virtually every color of the rainbow. This particular gem is a very unique, beautiful light blue Aquamarine from the Brazilian gem fields. This stone has some minor tube inclusions, but they really hide well when the stone faces up. The stone has a very unique and alluring "Concave Double Heart" cut. The stone recently was cut from a 40-year-old piece of rough that was stashed long ago. It's a very size stone for a pendant if you so wish, but it would stand alone as a great single stone in a shelf or gem box. Gem quality Aquas are becoming more and more difficult to buy (for reasonable prices) from Brazil, and it seems that the cost of these gems keeps going up every year.  A totally one-of-a-kind gem as it simply has a very unique cut, unlike 99% of the gems on the market today.

This stone is from the historic Mile 72 locality in the Swakopmund District of Namibia, and is the premier locality for Jeremejevite in the world. This stone is only one in this update that shows a slight purple overtone, which is quite rare in my experience. I think the saturation of this stone is exceptional, especially for the size. With that said, the color in this gem is a light medium blue, and not at all grey, yellow or colorless like many Jeremejevite gems from this area. The stone has a wide Trillion cut and is very attractive for the material. It is very slightly included. You do not see Jeremejevite gems on the market today, and the majority of the best crystals are stashed away in old collections and museums. A great opportunity to own a fine quality, colorful collector gem from a premier locality.

Cut stones of Jeremejevite are virtually impossible to find on the market these days, and the top stones are highly prized by collectors. This stone is from the historic Mile 72 locality in the Swakopmund District of Namibia, and is the premier locality for Jeremejevite in the world. This stone looks much better in person than the photos would indicate. Although it is very very slightly included, the inclusions are amplified by the fact that this small stone is magnified in the photos to several times its size. With that said, the color in this gem is a vibrant blue, and not at all grey, yellow or colorless like many Jeremejevite gems from this area. The stone has an Emerald cut and is very attractive for the material. You do not see Jeremejevite gems on the market today, and the majority of the best crystals are stashed away in old collections and museums. A great opportunity to own a fine quality, colorful collector gem from a premier locality.

Powellite from Nasik, India [db_pics/new09/rlkg061b.JPG]Powellite from Nasik, India [db_pics/new09/rlkg061c.JPG]

Powellite is among the rarest of collector gems. There is truly only locality in the world where facet grade Powellite occurs in any significance, which is Nasik, India. Powellites over 2 carats are rare, and the fact that this stone is over 5 carats is notable for sure. The stone is very well cut with an Emerald Brilliant cut and looks amazing face up. This gem is very very slightly included with a slight golden hue. I must say that this is one of the best gems in this update and would absolutely fit perfectly with a gemmy Powellite crystal as a "rough and cut" set. When it comes to the combination of rarity and quality, this stone is undoubtedly in the upper ranks.
