Antique emerald octagon cut engagement ring

absolutely beautiful antique ring. center stone is a Pariaba Tourmaline which is thought to be for people who bear a broken heart, as it encourages love, gently disperses emotional pain and dissolves disruptive feelings. It calms the negative emotions that upset relationships. But aside from all of that it is georgous. :) comes with history of tourmaline gems and a COA . I bought it at an estate sale in Salem Alabama. said it's been in her family for a long time and
