1.09 Ct. Alexandrite from Ceylon (Sri Lanka)

This 1.09 carat oval alexandrite exhibits a subtle and appealing color change, presenting a greenish hue under fluorescent lighting and shifting toward a warm orangish tone under incandescent lighting, a characteristic that reflects its natural chromatic responsiveness, The Natural Gemstone Company confirms the stone originates from Ceylon, Sri Lanka, and is untreated. The gem measures 6.95 x 5.38 x 3.58 millimeters, and is faceted in a mixed brilliant cut that combines a faceted crown and pavilion to optimize both brilliance and color return. The clarity is graded as very slightly included, evaluated at eye level, and these minor internal features do not materially affect the gem’s visual performance, the color intensity is classified as medium, and the polish has been executed to an excellent standard, providing crisp facet junctions and lively light performance. The combination of the oval outline and the mixed brilliant faceting yields a stone that balances face up size with depth, making it well suited to central settings that benefit from both color change and facet scintillation.

When considering complementary gemstones for a custom design, select accents that either enhance the alexandrite’s dual tones or provide neutral contrast. Small white diamonds arranged as a halo or as tapered side stones will increase perceived brightness and emphasize the stone’s shift between green and orange, while cognac or champagne diamonds will harmonize with the warmer incandescent appearance for a cohesive warm palette. For a design that highlights the green phase, pairs of green tourmaline or tsavorite garnets set at each shoulder will reinforce the cooler aspect without overpowering the primary gem. Conversely, small padparadscha or orange sapphires can be used sparingly to draw attention to the orangish side of the color change. Metal choice will further influence presentation, with platinum or 18 karat white gold offering crisp contrast and color separation, and 18 karat yellow or rose gold producing a warmer overall effect. The stone’s depth and durable mixed brilliant cut accommodate both bezel and prong settings, allowing secure mounting while retaining maximum light performance for a refined custom piece.
