Rubies from this classic locale are seldom found in good, aesthetic specimens. This piece features a 2-cm ruby crystal perched elegantly on a well trimmed matrix, and it has a great waxy luster and rich pink-red color. The rubies from here are typically more pink than Mogok rubies, and this specimen shows the best pink-red color that I like as a collector. The termination is full and sharp.

An impressive ruby specimen from the classic ruby mines here which date back even to Roman times. Large crystals in matrix are rare. Large GOOD crystals in matrix are almost unheard of. This is a rare example of such a piece, with a dominating 3 x 3 x 1.2-cm crystal sticking straight up and completely exposed on either side (a risky bit of prep work, that was!). The crystal is pristine and complete. As you can see it is also highly translucent and glows when backlit. This specimen was formerly in the Joe Freilich collection built by Dave Wilber, which was on short notice auctioned at Sotheby's in 2001. It was in Wally Mann's collection here in Dallas by 2003, where it has remained til now. Comes with custom base though I have to say it displays equally well from EITHER side.

This is a NEW RUBY MINE, and has been producing amazing bicolored red/purple rough for the gem trade recently but FEW crystals have been preserved. This matrix hosts a sharp, gemmy, intensely colored crystal of nearly 1 cm. It is obviously twinned, and REALLY is much more dramatic in person. In shifting lights, these change color and can show a bit of purple/blue color, even. I am told that normally even small examples of this material are cut for facet rough, and this specimen was one of the few collector-worthy pieces, saved from cutting by a good gem dealing friend of mine who throughtfully sold it to me based on carat weight - but hey, at least he didn't cut it before trying to preserve it!

The pigeon’s blood color in corundum is called ruby. All other colors are sapphire. THIS piece has THE color! The deeply colored ruby, 1.5 cm across, is translucent and highly lustrous. The crystal, 360-degrees complete all around, is aesthetically perched on contrasting white marble.

Incredibly gemmy ruby crystal, perched on matrix! This redefines what you might expect in a gem ruby specimen, particularly on matrix. Seldom are they GEMMY as opposed to "gemmy"...

Ex Bill Larson collection. Attached on one side by marble matrix, this is a dramatic, doubly-terminated, translucent, deepest pigeon’s blood red, ruby crystal. It has natural wet lustre...its har dto photo both the lustre and color so you have two different shots to emphasize each, if you can combine them more or less in your head. The crystal is 1.3 cm in length. It is well balanced on the matrix. The ruby crystal with its color and highlights represents the very finest quality that Mogok has ever produced, and this was stashed in Bill Larson's collection because of that. BETTER IN PERSON and when backlit, its amazing....probably better off displayed horizontally with the doubly-terminated crystal atop, but either way is good...

This is a superb, unusually sharp ruby crystal of a size we rarely see in good form, much less being on matrix. The piece is 2.5 inches tall overall and 2 inches wide. the ruby is blood red! there is a single crystal and a heartshaped twin! the twin is about 1.25 inches! this is majestic, and incredible for a specimen ruby at a mortal price range. Not only is it translucent, its gemmy in places...and its got CRYSTAL FORM here, not just a lump of color as are so many.

Although it is only weakly translucent (unless strongly backlit), this is a fine example of a doubly terminated ruby crystal on matrix and particularly good for the locality. The crystal is deep purple with red overtones and is 2.75 cm in length. It exhibits good satiny luster and contrasts nicely well with the massive white calcite matrix.

Sapphire color suite from Sri Lanka & Burma [db_pics/new2011/SAPPHIRES-7-78TCW-G44-2.jpg]

A fun set of 17 oval cut sapphires, in almost every color range, from Sri Lanka and Burma. Attractive as a mini-gem collection - or could be used to make a wonderful "sapphire rainbow" piece of wearable jewelry. We really like this one and highly recommend it for the price. Good cuts and excellent color saturation in these stones. And , all are natural untreated stones (assembled by semi-retired dealer Herb Obodda from his old dealer stock).

This well-exposed, dramatic ruby measures just over ONE INCH or 2.6 cm tall, and is perched beautifully on marble matrix. It is a VERY VERY sharp crystal for the locality and has excellent colro as well. When backlit, it practically glows with ruby-red light. Such large crystals , freestanding, are relatively rare on matrix and hard to obtain. This one is actually doubly-terminated, but perched in securely. It is about 80% translucent and additionally has a SHARP termination. Waxy lustre is what you want here, and you have it. Front and back of crystal are shown...

Star Sapphire from Sri Lanka [db_pics/new09/RLKG091a.JPG]Star Sapphire from Sri Lanka [db_pics/new09/RLKG091b.JPG]

This is a beautiful gemstone. Star Sapphires are among the most unique and desirable of all the Sapphire varieties. These stones are cut when thin, fibrous inclusions inside of the Sapphire crystal are oriented at the correct angle to properly show off the "legs" of the star. When these inclusions are numerous enough to make the stone translucent or opaque, they allow light to be reflected in such a way that a star floats” across the top of the dome of the gem when it is rotated in the light. It is an amazing phenomenon that is only seen in a few gems around the world. The actual "legs" of the star in this stone are amazingly sharp, with virtually no breaks and excellent consistency throughout. The stone also exhibits a light lavender blue color, and is a fantastic example of a classic Sri Lankan Star Sapphire.

Sapphire is one of those gems that comes in virtually every color of the rainbow. With that said, the most recognizable and popular color of Sapphires by far is blue. I've seen literally every shade of blue known to man exhibited in Sapphires, and they are still some of the most admired, durable and highly sought after gems on the planet. This stone has a strong royal blue color face up, and looks beautiful in both sunlight and incandescent light. The stone is very slightly included and has a standard "Step Oval" cut. It is a very attractive example of this storied material.

This stone has a beautiful "royal blue" color which shows up well in strong light. The stone is very slightly included and has an Oval cut, which is common for Sapphires.

In 1984 Charlie , along with John Barlow , sponsored a collecting trip to Nepal for these. I have his note on the back of an old business card that states, in his opinion, this was the best crystal found. Note the winding core in the middle which is a sapphire core, something rarely seen and in need of some study to figure out why this is going on! There is probably some neat gem rough to be cut from this, with the ruby rind around a purple sapphire core. The specimen is completely WEIRD, in that it tapers from a narrow base to a wider termination which shows multiple trigonal faces. The termination has some damage on the back edge, but not in front. Note there IS one repair about the middle, so its not perfect by any means; but it IS a beautiful and very intense gem crystal that leaps out from a showcase, and the flaws are noted in that context. It is repaired at the midpoint but, you do not really mind so much in person, when the gemminess and intense color impact is taken into account (and otherwise this would be a 10k thumbnail anyhow). The color is not intense, it is almost metallic in "style" and really jumps out.
