So Blue
Natural untreated blue zircon drops totalling 1.52 ct and set in platinum on platinum Grape studs. Here again, natural zircon (no, please don't confuse it with CZ) is a gemologist's, and gem dealer's gem. Beautiful blue.
Gems are removable. See how the hook works in the second picture of Flat Black, here: https://www.disegnojewellery.ca/products/flat-black
