A rare 8.20 carat emerald cut Indicolite Tourmaline, offered loose and unmounted for collectors, gemstone connoisseurs, and clients seeking a remarkable center stone for a bespoke jewel. Known for its deep blue green color, Indicolite is one of the most captivating varieties of tourmaline, admired for its oceanic depth, refined saturation, and sophisticated color character. This gemstone displays a rich blue green tone that shifts beautifully with the light, moving between cool teal, deep sea blue, and greenish blue depending on the angle and environment. The emerald cut enhances this natural beauty with clean geometry, long step facets, and a calm architectural presence. Rather than relying only on sparkle, the stone reveals depth, clarity, and quiet power through its elegant lines. The substantial 8.20 carat weight gives this Indicolite Tourmaline impressive presence while still feeling refined and wearable. Its elongated emerald cut shape makes it especially suited for a bold cocktail ring, a distinctive alternative engagement ring, a meaningful right hand ring, or an heirloom pendant designed around color, structure, and individuality. Indicolite Tourmaline is often associated with calm strength, communication, emotional clarity, and inner balance. Its blue green color carries the feeling of water, renewal, and depth, making this gemstone meaningful for someone drawn to rare color and personal symbolism. It is a beautiful choice for a client who wants a jewel that feels powerful, serene, and unlike ordinary gemstone jewelry. Offered by Merkaba Jewelry Beverly Hills, this loose gemstone is ready to become a one of a kind creation through our custom “Design Your Dream” service. It may be designed in platinum or 18K gold, with optional diamond accents tailored to the stone’s proportions and the client’s preferred style. Whether imagined as a clean modern solitaire, a diamond accented cocktail ring, or a refined pendant, this Indicolite Tourmaline offers exceptional design potential.
