CR1613 Tanzanite, 3.36 carat, 1.2 cm tall. $95. Crystal is in excellent condition with good color saturation. This has an original price tag on it of $150
I have acquired a number of tanzanite crystals from Merelani, Tanzania. Several sources have noted that the tanzanite deposits are becoming depleted and good crystals are getting harder to find.
CR1614 Tanzanite, 4.11 carat, 1.08 cm tall. $95. This crystal is in excellent condition. A bit 'blockier' than the one above, with good color saturation. This has an original price tag on it of $120, though in my opinion it as nice as the one above so I have priced it the same. It shows stronger pleochroism, with a distinct purplish color when backlit and viewed from the side.
CR1615 Tanzanite, 4.89 carat, 2.0 cm tall. $95. This crystal is in excellent condition. This crystal has the classic wedge shape, is a bit cloudy at the base but good clarity in the upper part and with minor edge rubbing along the termination. The color is a bit lighter, probably primarily due to it being thinner. This has an original price tag on it of $150.
CR1616 Tanzanite, 7.17 carat, 1.58 cm tall. $110. This crystal has good color saturation and displays well, though there is minor damage to the back, seen in the photo on the right. There was no original price tag on this, but $120 seems a very fair price considering the minor damage. Undamaged, this crystal would easily be worth $300
CR1617 Jeremjevite, Erongo, Namibia,2.60 carat, 1.97 cm tall. $55. Etched crystal, good overall clarity. This apparently was a 'one-time' find, though I'm sure people must be looking for additional pockets.
CR1628 Spessartine Garnet, Loliondo, Tanzania 47.73 carats, 1.98 cm longest dimension. $145. Well formed crystal faces all the way around. No damage. This crystal is a little darker than some of them. I have seen similar crystals of this size priced at over $1000.
CR1631 Spessartine Garnet, Loliondo, Tanzania 36.01 carats, 1.63 cm longest dimension. $145. Well formed crystal faces all the way around. No damage. This one is a bit brighter than the one above, but smaller. I have seen similar crystals of this size priced at over $1000.
