Sapphire (great color) from Vietnam [db_pics/new2010/rlkg251a.jpg]Sapphire (great color) from Vietnam [db_pics/new2010/rlkg251b.jpg]

Sapphire is one of those gems that comes in virtually every color of the rainbow. With that said, the most recognizable color of Sapphires by far is blue, but pink Sapphires are some of the most vivid and recognizable gems in the world. I've seen literally every shade of pink known to man exhibited in Sapphires, and they are still some of the most popular, durable, colorful and highly sought after gems on the planet. This stone has an electric pink color, and hails from what is quickly becoming one of the premier areas in the world for these stones. The stone is virtually eye clean and has a standard "Oval" cut.

Most sapphire crystals are long prismatic and terminate in pyramids. This glowing, hot-bubble-gum pink, translucent and super-lustrous, sapphire is really unique and special! It is short and prismatic, and doubly terminated - a floater all around! The specimen clearly exhibits hexagonal shape. This could be cut into a cabochon, just for its color. If transparent, this specimen would sell for tens of thousands of dollars. As a specimen, it will leap out amongst any corundums, rubies, sapphires. It is REALLY intense...the rightmost pic is more accurately colored and even that pales in comparison to the actual piece. Out of hundreds of these I have seen, this ONE is most special.


T07-75 - Ruby in Scapolite - $ 2250

Although it does not exhibit classic crystal form which makes the name ruby jump out at you, this ruby does have an unusual color zoning, where the periphery is more deeply colored in classic ruby red lipstick outlining around a slightly lavender-hued center. It is on massive, gemmy, scapolite matrix...the ruby so transparent that the underlying scapolite is easily discernible. This is a fascinating corundum specimen, totally different than any other ruby you may own and for me, all the more interesting for that fact. Just blew me away when I saw it and realized what it was.

Sapphire (twinned) from Passara Gem Mine, near Ratnapura, Sri Lanka [db_pics/pics/t08-06b.jpg]

This exceptionally sharp sapphire crystal shows flanges to the sides that reflect a rare, well-formed twinning habit. Seldom do you see such a twin in the species, and usually it is present in rather clunky crystals. Specimens this sharp are hard to get because they mostly come from the gem gravels where they have been rolled and damaged in the past. This piece, however, comes from an excavation nearby and the crystal is nearly pristine. In person, it is extremely lustrous and bright! The bottom termination extends backwards in depth, showing a SECOND twinning plane in that the bottom section is rotated 90 degrees to the main body. If you hold this in your hands, in other words, it looks in person like an airplane, with the wings (upper twin flanges) in one plane and the bottom twin (rudder analogue) rotated into another plane around the core axis. Weight is approximately 25 carats. This crystal was sold as gem rough, by weight, at one of the gem shows. The price of $100 per carat is frankly not much of a markup since I had to buy it based on its weight as gem rough that could be treated and cobbed!

A bizarre yellow sapphire with a weloganite-shaped body, illustrating either twinning of some kind or just a weird "pinch" about the middle of a single crystal. The ends are terminated with a simple hexagon, and the piece is thus a floater. It is VERY sharp, showing none of the rounding normally associated with many Sri Lankan crystals found in the alluvial gem gravels. Weight is approximately 14 carats. This crystal was sold as gem rough, by weight, at one of the gem shows: I had to buy it based on its weight as gem rough that could be treated and cobbed!

WOW! This specimen features a doubly-terminated ruby crystal perched atop contrasting matrix! It is gemmy and bright, with vivid color especially when backlit. Large, matrix rubies of this calibre are NOT common and it is a piece that is far better in person than conveyed in the pics.


Tmix07-151 - Corundum var. Ruby - SOLD

Corundum var. Ruby from Bianco Sivec Quarry, Prislep, Macedonia, Greece [db_pics/pics/tmix07-151a.jpg]

This is a significant, near floater, euhedral, ruby crystal. It is complete all around and has a sharp form distinct from that of other localities for rubies. It has great color, translucence (when backlit, it practically "glows"), luster, and size. That it is from a centuries old location whose name had all but disappeared from the literature, only adds to its mystique and beauty. I buy them when they turn up , and this is one of the best I can say I have seen for both size and quality.

This 1.5 x 1.4 x 0.9 cm ruby is blood red, with the top color more characteristic of a Mogok ruby than of Afghanistan (they tend to be a little more pink). It shows extremely fine crystal form, and is perched on contrasting marble matrix. Together, one of the best ruby thumbnails I can recall seeing from anywhere and certainly of top quality for Afghanistan

An unusual crystal in several respects, for both its strong, vivid yellow-orange color ; and for its twisted form. This specimen weighs 53 cts and is a complete floater. Its surreal, curving form is graceful and bizarre. As well, I just have never seen such a color-saturated sapphire in this hue, as a natural crystal, before. It is a really stunning piece, in person

This superb, doubly-terminated gem crystal is 34.67 carats, and has a classic unheated steely-blue color. Specimens of this size tend to show rolling and rubbing from their source environment in the gem gravels, but this specimen is very sharp, still. From the noted gem crystal thumbnail collection of Dr. Jim Houran. This specimen was featured in the "THUMBNAIL COLLECTORS GATHERING" case of Tucson 2010 and comes with the commemorative label.

Ruby on marble from Jagdalek, Saroby, Afghanistan [db_pics/new2012/Ruby-Jagdalek-Afghanistan-56mm-JB552-UVA-24.jpg]

A fine miniature from the 1990s production here, and out of the noted collection of Dr. Ed David (former Nixon science advisor). The main crystal is actually doubly-terminated, and floats in the matrix perfectly situated for contrast by the preparator who worked it out. the crystal is sharp, textbook in form; and has an intense red color and classic waxy luster. It has one very clean repair in the middle, considered acceptable to me in a ruby of this size and quality, as it had to be worked out of the matrix to display as nicely as it does. Note the shocking fluorescence under ultraviolet light, as a bonus. Joe Budd Photos.

A classic Russian sapphire specimen of this very unusual roseate habit, which looks like a flower. We see many partial examples, or pieces, but few so complete as this one from here. It has, in person , more of a robust blue color in fluorescent lights. Joe Budd Photos.
