K18PG Brazilian color shift amethyst, hackmanite, pink sapphire ring
This ring features amethyst and colored stones. The center amethyst is a rare heptagonal shape with a lovely deep purple color. The side stones are set with colorful colored stones such as pink sapphire, hackmanite, and tanzanite, giving it a cute impression. Hackmanite fluoresces and glows under black light, so you can enjoy it by shining a light on it.
This is a 4.6mm octagonal cut color-shifting amethyst from Brazil, polished by Sri Lankan cutter Sanjay.
