Greetings to you all,
I need help identifying the black-blue rock below. The lab analysis shows that it is 91.7% Andradite and 8.3% Cuprite, with a density of 3.7.
From my research it appears to be a garnet, but I am unsure if the Cuprite component changes its classification?
I am new to the gemstone world and have limited knowledge in this field. Any assistance will be highly appreciated.
