Ruby - Uncut - North Carolina - 1970s Value Help


#21

Shine a black-light light source on it. If it fluoresces a strong deep red, I typically consider it ruby.

It looks like its large enough it can handle being cabbed and carved. Carving an intricate design on the cab dome, if done well, can give the stone a strong boost in value.

Also sapphire and ruby are both corundum. Color is what separates ruby from sapphire. To the best of my knowledge. Nice piece either way.
