Info about gems shown in preview pics (per one single earring):

Estimated weight for one single earring:
OBJ's was exported from Rhino as meshes and as NURBS surfaces & polysurfaces. Not tested (anyway model was natively made in Rhino for production and succesfully produced and sold and in this case OBJ is useless. I'm adding it just for better publishing score due to silly CGtrader better publishing recomendations)
