Apatite from Slyudyanka, Transbaikalia (Siberia, CIR)
No. 354: 9 Main Pear Meetpoint, 5.15 ct., 14.0 x 9.6 x 7.6 mm, SI1, $206.00
This is a very unusual stone from an historic location. Because
of strong dichroism, this gem shows blue flashes over a light yellowish-green base
color; a truly unusual color effect. The material itself is slightly "sleepy"
with a veil nearly perpendicular to the table. Little of this material reaches the
market and even less gets cut into gemstones. Tiny included needles in this material
make this an extremely difficult material of successfully polish. It took over 20
stressful hours (Including pronouncement of more than a few expletives) to complete
this gem. This particular stone has been heated to remove the green color and leave
the stone with a more blue appearance. The resulting color is stable. Apatite is
a soft material that requires the skill of an expert metalsmith to be set without
damage. This stone would be a very special addition to a gem collection.
