Help identify this stone - Andradite?

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.

Might you mean Azurite?.. it has a specific gravity of 3.7 and often occurs with, or as a replacement of Cuprite and does the dark blue thing really well. Good luck!
