rapidly being depleted).

Fiskenaesset Ruby
Location:
Fiskenaesset Complex, Southern Greenland |
|
|
|
|
Ruby crystals appear as single crystals
and clusters up to several centimeters at several of the sapphirine
localities in the Fiskenaesset area. The color varies from rose-red
through pigeon-blood red. Fiskenaesset rubies have an unusually high
chromium content (up to 3.0%) and are reportedly strongly fluorescent
under LW UV light.
Rough Slabs available in the
Gemstones Section
Most of the crystals are opaque but
some are translucent/transparent but very rare. This material is well
suited for cabochons and the resulting piece is a wonder of colors -
ranging from deep red, green, yellow, gold, white, black, and many
colors in between.
The red porphryitic corundum (ruby)
crystals are set in an amphibolite matrix dominated by green hornblende
with minor biotite mica. There is some accessory sphene. |
