1.40 Ct. Moonstone from Madagascar

This transparent 1.40 carat oval rainbow moonstone measures 8.02 by 6.09 by 5.06 mm, and is expertly fashioned in a mixed brilliant cut that combines a brilliant crown with a precisely faceted pavilion to optimize internal light dynamics and adularescence. The depth to average dimension is approximately 72 percent, a proportion deliberately chosen to enhance the internal sheen while preserving table presence. Clarity is graded slightly included at eye level, with inclusions that are characteristic of natural moonstone and that do not detract from the overall transparency or play of light. Color intensity is light, allowing a delicate body color that serves as an ideal backdrop for the rainbow flashes, and the polish is excellent, yielding crisp facet junctions and a satiny surface finish. This stone is untreated, with no enhancements, and is sourced from Madagascar, a region known for producing transparent moonstones with fine adularescent qualities. The mixed brilliant architecture, combined with careful symmetry and a well executed girdle, produces consistent light return and a balanced face up appearance that is suitable for both fine jewelry settings and collector specimens.

The visual performance of this moonstone will continue to captivate over the years due to its inherent optical properties and careful cutting. The adularescence exhibits layered spectral flashes that shift with movement, creating an enduring sense of depth that evolves under different lighting conditions, and because the gem is natural and unenhanced, its appearance will age gracefully without alterations in treatment. The excellent polish and robust proportions contribute to surface durability, while the slight inclusions offer a fingerprint of natural origin that appeals to connoisseurs who value authenticity. For long term enjoyment, routine gentle cleaning and protective setting choices will preserve the stone, allowing its translucent body and rainbow sheen to remain as compelling as the day it was cut. The Natural Gemstone Company offers this specimen to discerning buyers who appreciate technical craftsmanship, natural origin, and the subtle, evolving beauty that only a well cut rainbow moonstone can provide.
