Hi, i have lots of lesser know Gems, but here are two to kick this thread off.. 20.40 CT Ametrin (Type of Quartz) Octagon Cut Natural 1.13 APATITE NATURAL OVAL BLUE GREEN (One of my personal Favourite Stones) 1for1
With the exception of large gem specimens Apatite is not really expensive stone, it is also common in yellow , and maybe some other colors. It is a beautiful stone but very soft, I would put it in the category of beautiful but no love stones such as Iolite ,Zircon, Spinnel, Kunzite(maybe),Sphene, Sunstone etc. .Generally desirability and value of stones are in Color , Clarity and treatment, and with those established Hardness is King.. This Looks to be a very nice example of of a Blue Apatite!
