Soft, dreamy, and completely one-of-a-kind, this 3.12 ct natural watermelon tourmaline showcases a beautiful blend of pastel pink and mint green — a delicate “watercolor” bi-color zoning that makes this gem feel ethereal and romantic. Sourced from Africa and expertly faceted into an elongated emerald-cut silhouette, it displays a clean, linear transition between colors that collectors love.
This gemstone’s gentle tones make it perfect for someone who prefers subtle elegance over bold saturation. Its elongated profile offers gorgeous finger coverage for a custom ring, or a graceful vertical presence in a pendant. Each stone from our Coastal Carats Gem Library is personally hand-selected for its uniqueness, personality, and potential to become a meaningful heirloom.
Available loose for collectors or ready to be transformed into a bespoke 10k, 14k, or 18k gold piece through our custom design studio.
