2.31 Ct. Chrysoberyl from Ceylon (Sri Lanka)

This specimen is a transparent 2.31 carat cushion shape green chrysoberyl, measuring 9.15 by 6.70 by 4.64 millimeters, cut in a mixed brilliant style to optimize both scintillation and color saturation. The mixed brilliant treatment pairs a brilliant style crown with a pavilion that emphasizes controlled light return, creating a lively play of pinpoint flashes across the table and crown facets. Color is intense, a rich medium to medium deep green with strong saturation that remains consistent under standard lighting, and the surface exhibits an excellent polish producing an adamantine luster characteristic of fine chrysoberyl. Clarity is graded very slightly included at eye level, with inclusions minimal and not disruptive to the overall transparency or face up appearance, and the stone has received no enhancement, confirming its natural color and surface condition. The origin is Ceylon Sri Lanka, a provenance known for producing chrysoberyl with clean color and superior cutting material, and the combination of weight, dimensions, and mixed brilliant faceting yields a visually substantial gem that maintains excellent optical balance.

From a gemological and lapidary perspective this cushion chrysoberyl demonstrates careful proportional planning. The mixed brilliant cut uses a relatively high crown with well defined star and kite facets to break up light into tight scintillation, while the pavilion facets are arranged to limit windowing and maximize internal reflections. Facet junctions are sharp and facet symmetry is precise, which together with an excellent polish enhances facet contrast and produces crisp, lively facet flashes. Optical properties of chrysoberyl contribute to the gem s performance, with a refractive index in the range commonly reported for chrysoberyl which generates strong brilliance and a distinct bite to facet reflections, and a hardness of approximately 8.5 on the Mohs scale that supports daily wearability in ring and bracelet designs. The very slightly included clarity grade indicates inclusions are small in size and primarily located in the lower half of the stone where they are masked by the mixed pavilion construction, and because the gem has not been subjected to heat or other treatments its natural color and internal character can be relied upon for long term stability.

When considering custom settings and complementary stones, this cushion green chrysoberyl responds exceptionally well to both contrast and harmony strategies. For contrast, pairing with near colorless diamonds enhances perceived brightness and optical contrast, a halo of fine white melee or a three stone arrangement flanking the chrysoberyl with tapered baguettes will emphasize the gem s intense green while preserving brilliance. For richer, warmer palettes, small fancy yellow or cognac diamonds introduce a complementary warmth that deepens the green visually when set in 18 karat yellow gold, while pink sapphires or rubies deliver striking color contrast for a bolder, high impact composition. For a tonal approach, mint green tourmaline or peridot in calibrated sizes can create a layered green field that reads as sophisticated and restrained. Metal choice is a functional design decision as well, with platinum or white gold maximizing the gem s scintillation and white light return, and 18 karat yellow or rose gold adding warmth that accentuates any subtle yellowish undertones and complements surrounding warm accent stones. Practical settings include four to six prong solitaire mountings that maximize light entry, low profile bezel options for secure everyday wear, and halo settings where a precise calibrating of melee sizes between the center chrysoberyl and surrounding stones ensures optical harmony and structural balance.

At The Natural Gemstone Company we prioritize matching lapidary expertise with design practicality, and we can provide detailed facet plans, high resolution imagery, and recommendations for specific side stone weights and metal selections to achieve the desired visual effect and wearability. Whether the objective is to maximize the chrysoberyl s brilliance in a solitaire, to create a dramatic contrast with colored sapphires and warm gold, or to design a modern halo using near colorless diamonds and platinum, this 2.31 carat Ceylon cushion green chrysoberyl offers a rare combination of intense natural color, precise mixed brilliant cutting, and excellent polish that responds predictably to refined custom settings.
