0.69 Ct. Alexandrite from India

One beautiful transparent alexandrite offered by The Natural Gemstone Company weighs 0.69 carat, and presents an elegant oval outline with dimensions of 5.85 by 4.87 by 3.15 millimeters. The stone is faceted with a mixed brilliant cut, and exhibits an excellent polish that allows clean and lively light return. Clarity was graded as eye clean when evaluated at eye level, and color intensity is classified as medium. This is a natural, untreated gem, with no enhancement reported, and it is of Indian origin. The combination of weight, proportions, and workmanship produces a gem that reads as balanced and refined when viewed on the hand or in a setting.

The defining visual attribute of this alexandrite is its color change, which shifts from a greenish tone in fluorescent or daylight conditions to a purplish hue under incandescent light. This rich, bold color shift serves as a symbol of personal power and distinction, offering a dynamic presence that responds to the wearer and the environment. The color phenomenon is a characteristic of alexandrite type material, produced by specific trace elements and the stone chemistry that selectively absorbs and transmits different wavelengths of light. The medium color intensity allows the color change to read clearly without appearing overly dark, and the result is a versatile gem that conveys both subtlety and visual authority.

The mixed brilliant cutting style employed here is intended to balance spectral color and brilliance, and the faceting pattern concentrates light to emphasize both the greenish and purplish tones in their respective lighting conditions. Depth measures approximately three point one five millimeters, producing a depth to average diameter ratio of approximately fifty nine percent, a proportion that supports good light performance for an oval of this size. The excellent polish enhances facet crispness and ensures that the pavilion and crown facets interact cleanly, contributing to the overall scintillation. Because the gem is eye clean at normal viewing distance, the surface and internal clarity combine to allow the color change to be seen without distraction.

As a natural, untreated alexandrite from India, this gem represents an authentic example of the material, suitable for use in rings, pendants, or earrings when set with appropriate protective consideration. For ring settings, a bezel or secure prong mounting is recommended to protect the girdle and pavilion while still allowing light to reveal the color change. Care consists of routine gentle cleaning with warm water and mild detergent, avoiding harsh chemicals and extreme thermal shock. The Natural Gemstone Company presents this stone as a single, distinctive specimen, offering clear technical information on weight, dimensions, cut, clarity, polish, origin, and enhancement status, to assist in appraisal and design decisions. The rich, bold color change of this alexandrite is an emblem of personal power and distinction, and the gem is presented with the straightforward technical detail appropriate for professional consideration.
