1.53 Ct. Tourmaline from Ceylon (Sri Lanka)

An exceptionally rare treasure awaits the discerning collector, a transparent 1.53 carat cushion shape green tourmaline that embodies both refined taste and natural prestige. Meticulously cut to 6.85 x 5.50 x 4.33 mm with a mixed brilliant cut, this gem displays a dance of light that is at once lively and sophisticated. Evaluated at eye level, the clarity grade reads very very slightly included, allowing the stone to present an open window of pristine transparency while retaining the character that attests to its natural origin. Its intense color intensity and excellent polish produce a depth of green that feels almost living, a green that moves from verdant to jewel deep as the angle of light shifts. There has been no enhancement to alter its inherent beauty, and its provenance from Ceylon Sri Lanka places it among a select group of tourmalines whose origins confer both rarity and a storied pedigree. The Natural Gemstone Company presents this gem as a singular offering, an opportunity to own a stone that will not be replicated in our inventory.

The mixed brilliant cut has been chosen to maximize scintillation while preserving the generous proportions of the cushion silhouette, resulting in a presentation that is timeless and modern at once. Cushion shape continues to be a favorite among connoisseurs because it bridges classic elegance with contemporary appeal, and this specimen demonstrates that balance with exceptional success. Under careful scrutiny, the very very slightly included clarity grants a gentle assurance that the gem is naturally formed and authentic, without distracting from the overall purity of appearance. The intense color intensity is not uniform in its beauty, it offers nuanced zones and flashes that reward prolonged viewing, revealing subtleties of tone that only a high quality tourmaline can deliver. The excellent polish means every facet edge is crisp, every plane finely finished, and together with the mixed brilliant faceting this creates lively return of light, a jewel like presence that will read with authority in any setting. For those who appreciate the combination of natural origin, meticulous cutting, and ethical sourcing, this stone from Ceylon Sri Lanka stands as a distinguished choice.

When assessing durability the Mohs scale is an important reference, and green tourmaline sits at approximately 7 to 7.5 on that scale. This positioning means tourmaline is notably harder and more resistant to scratches than softer gems such as opal or pearl, and it holds up well against daily wear with appropriate care. It is less hard than topaz at 8, sapphire at 9, and diamond at 10, so while it will resist many everyday abrasions, it is not immune to impact or forceful knocks. Compared with emeralds that are often heavily included and sometimes more fragile in practical wear, a very very slightly included tourmaline can offer a reliable balance of toughness and brilliance. For owners who intend to wear this gem in a ring that sees regular use, we recommend settings that protect the girdle and corners, and routine gentle cleaning by soft cloth or mild warm soapy water, avoiding harsh chemical cleaners and professional ultrasonic treatments when inclusions are present. With mindful care, the integrity of this 1.53 carat cushion will endure, allowing its beauty to be enjoyed for generations.

Ownership of a gemstone of this caliber is an invitation into a rarefied circle, a chance to possess something that is inherently finite and exquisitely formed. The Natural Gemstone Company curates each piece with an eye toward uniqueness, and this green tourmaline is offered to those who seek distinction and depth of character in their jewels. Because this specimen is untreated and originates from the renowned deposits of Ceylon Sri Lanka, it bears a story of place and process that is increasingly uncommon in a world of mass produced alternatives. We extend exclusive assistance to ensure the gem finds its ideal setting, whether your vision is a bespoke engagement ring, an heirloom pendant, or a one of a kind commission. Prospective custodians are encouraged to inquire promptly as stones of this nature are rarely held in inventory for long.
