Beautiful gold color ring with bluish white opal looking stone.

Beautiful gold color ring with white opal looking stone, unsure what stone this is, but it is very translucent and will pick up blues and whites depending on the lighting. Size 6.5 Stamped .925 with a small heart on inside band Estate sale item, so no other info available, but this ring is beautiful! Your business is always appreciated! Smoke free home! Reasonable offers always considered! Due to the difference between different monitors and lighting, the picture may not reflect the actual color of the item. Thank you
