3.77 Ct. Tourmaline from Ceylon (Sri Lanka)

Presented by The Natural Gemstone Company, this exquisite greenish brown tourmaline is a study in refined restraint and natural splendour. Weighing 3.77 carats, and measuring 11.80 by 8.53 by 5.47 millimeters, this oval gem commands attention without ostentation. Cut in a mixed brilliant style, it balances scintillating crown facets with a carefully faceted pavilion, creating a lively interplay of light and depth. The stone is transparent, with a clarity grade of very very slightly included evaluated at eye level, and it benefits from an excellent polish that allows every facet to perform with precise brilliance. Originating from Ceylon, Sri Lanka, and completely free of enhancement, this tourmaline is a rare, naturally vivid expression of the island’s storied gem traditions, offered to discerning collectors who value provenance as much as beauty.

The color of this tourmaline is intense, an elegant greenish brown that shifts with movement and light, revealing olive undertones that melt into warm cognac highlights. In certain lights the gem reveals deeper forest green hues, while in others it leans into a luminous amber brown, giving it a chameleon quality that is both sophisticated and endlessly intriguing. The mixed brilliant cut enhances its internal glow, producing flashes of light from the crown and dramatic refractions from the pavilion, so that the gem reads as richly alive on the hand or set in a bespoke piece. At 11.80 by 8.53 millimeters it is generous enough to serve as a striking solitaire, yet versatile enough to sit gracefully within a halo or a refined three stone composition, each setting option elevating the gem in different directions depending on the wearer’s personal style.

Beyond beauty, this tourmaline offers reassuring durability for regular wear, rated between seven and seven and a half on the Mohs hardness scale. To put this in context, diamond is a ten, ruby and sapphire are nines, and quartz is seven, so tourmaline sits comfortably above many common gemstones while offering a balance of toughness and workability that makes it suitable for a variety of jewelry types. With a hardness of seven to seven and a half, it is resilient to everyday wear, yet it benefits from considered design choices that protect its girdle and pavilion. For high use pieces such as daily wear rings, we recommend protective settings such as a low bezel or a substantial halo and shoulders to shield the stone from hard knocks. For pendants and earrings where impact risk is naturally reduced, this tourmaline will retain its polish and brilliance with minimal maintenance, while occasional professional cleaning and mindful storage will preserve its natural radiance for generations.

Owning this gem from The Natural Gemstone Company is more than acquiring a fine jewel, it is a declaration of connoisseurship. The combination of intense, natural color, transparent clarity with very very slight inclusions at eye level, exacting mixed brilliant cutting, and the island provenance of Ceylon together create a piece that speaks to refined taste and a desire for authentic rarity. This tourmaline is offered untreated, a pure example of nature’s artistry that invites a bespoke setting to translate its character into wearable art. For collectors and patrons who seek a meaningful acquisition, we can consult on mounting options, bespoke designs, and certification, ensuring the piece you commission or purchase becomes an heirloom that reflects your personal narrative and enduring style.
