Koa “Blue Sapphire” Necklace

Our rubies and sapphires are 100% genuine, enhanced with lattice diffusion, a heat treatment that enriches their color and durability. For our emeralds, we use recrystallization, bonding real emerald particles under heat and pressure to create a lasting gem. These are genuine stones, refined for beauty that lasts—perfect for your every day, and a price you’ll love
