Description

 Cuprospinel (aka:Copper Spinel) ~ 0.80ct


Stunning!


Cuprospinel is an inverse spinel with the formula CuFe2O4, where copper substitutes some of the iron cations in the structure.


There is no documentation as to whether this is an untreated/non-synthetic stone.  However, we are fairly certain that this stone has been heat treated to achieve the desired color.


Additionally…


The proper way to analyze whether Spinel is real is to put it under a UV Radiation Light. Set it to long-wave and look for any stones that are particularly “glowy”. If the stones are “glowy”, that may imply that they are synthetic and not natural.


According to TCA's own long-wave UV emitter, this stone did not appear "glowy".  However, without a proper chemical analysis this is all we can definitively claim.


Gemstone:  Spinel

Color:          Copper

Cut:             Oval, 7x5mm diameter

Size:            0.80ct
