Zircon
Color: Medium Dark Slightly Greenish-Blue
Clarity: Eye Clean
Origin: Cambodia
Cut: Cushion Brilliant
Treatments: Heat
Measurements: 7.7 x 5.8 mm
An extremely fine matched pair of classic Cambodian blue Zircon. Commercial grade stones are still the widely accepted norm with these, so cutting is often slightly less than perfect and the proportions and outline slightly askew. Not at all the case here, these have been freshly cut to our standards and extremely fine both individually and in terms of match. The color is a perfect medium dark hue accented by Zircon’s high optical properties and the set dazzles when touched with light.

Green Zircons have enjoyed some attention recently. All of the 'other' colors of Zircon, in fact, are enjoying some long overdue recognition. There is actually quite a range for the greens of this species - this one is of the darker, 'evergreen' persuasion. It is quite clean, well cut and has the lovely and distinct ‘metamict’ pattern of tight lines visible upon close inspection.. Quite brilliant and competitively priced for these now.

A nearly 30 ct precision cut Zircon will most always be rather impressive by its sheer presence. This one has a rather special bonus about it - a light cloud of what might be a growth strain feature or perhaps a kind of crystal alteration that can catch the light and reflect. This effect is similar to a schiller caused by inclusions, though that doesn’t seem to be the case here. The color is a silvery-white so it does resemble adularesence in some regards; either way, it is an interesting effect and one that is subtle enough that the stone appears largely clean when rotated. Great cutting and an interesting color as well - there is a bit of shift with the greenish/brownish modifier dependent on the light source.

Color: Medium Slightly Greenish-Yellow

Origin: Mogok, Burma
Cut: Natural Crystal
Treatments: None
Measurements: 10.8 x 5 x 4 mm
We will be the first to say that we no idea what the inclusion is in this fascinating natural crystal. Much has been made of Zircon as inclusions in Corudum from Mogok, but gem Zircon from Mogok is not really a player in the market and isn’t much studied. What is undeniable is the attractive nature of this glassy and well-formed gem crystal with a little nebula of brick-red inclusions at its center. A gem with a story certainly.

An absolutely superb matched pair of classic Cambodian blue Zircon. Commercial grade stones are still the widely accepted norm with these, so cutting is often slightly less than perfect and the proportions and outline slightly askew. Not at all the case here, these have been freshly cut to our standards and extremely fine both individually and in terms of match. Moreover, the color is exceptional - the deep, darker blue that is considered absolute top for these. Accented by Zircon’s high optical properties, this set dazzles when touched with light. A large set of the finest quality.

A gorgeous and essentially perfect pair of accent blue Zircons. The color is great and extremely well matched and the cutting is excellent - these were cut to match and look it - calibrated as well. Brilliant and bright.
