4.3 x 4.1 x 3.7 cm (Specimen); 2.11 carats; 7.50 x 7.31 mm (Faceted) & 1.35 carats; 7.58 mm x 5.92 mm (Cabochon) - Moonstone is soft sometimes milky stone, but the most valuable variety of this Feldspar is those with a sheen. Moonstone shows a silvery or bluish iridescence, sometimes called "adularescence". The specimen in this three piece rough and cut set features sharp, blocky, translucent crystals from Tvedestrand, Norway measuring up to 2.1 cm and when they're rotated in the light, you can see a slght blue sheen. The faceted gem is actually from India with a very soft golden interior when viewed in direct light, but if you rotate it, you can clearly see the iridescence. Lastly the "Oval" cabochon gem has the best clarity of all three items, and is virtually colorless but you can still see a slight sheen when you look at it under a strong light.
