This is the last A-grade stone for the Santa Maria Aquamarine necklace top. Grid: 5mm ~~~~~~ This stone is from the Santa Maria mine, sourced a long time ago from a buyer in Okachimachi. While it's in the light blue range rather than navy, it has good color, luster, and brilliance, and the size is also excellent. The pear-shaped cut gives it a classic feel. Nowadays, aquamarines with a deep color are commonly referred to as "Santa Maria Aquamarine" or "Santa Maria Color," but this is because the aquamarines from the Santa Maria mine in Minas Gerais, Brazil, were exceptionally blue and beautiful. Since the Santa Maria mine has already closed, these stones are highly sought after in the market and are also popular as collectibles. ~~~~~~ #SantaMariaAquamarine #Earrings #Earrings #Charm #14kgf #K14GF #GoldFilled #minamoYURAgi
