0.73 Ct. Alexandrite from Russia

This listing presents a transparent 0.73 carat cushion shaped alexandrite, with exact dimensions of 6.43 by 4.37 by 3.23 millimeters, a mixed brilliant faceted cutting style, and an excellent polish. The gem displays a classic alexandrite color change from a bluish tone in daylight or fluorescent lighting to a reddish tone under incandescent light, a phenomenon that is clearly evident given its intense color response. Clarity has been evaluated at eye level and is graded slightly included, which means the stone contains small natural inclusions that do not significantly interfere with its overall transparency or brilliance. This specimen is untreated, no enhancement, and is documented as originating from Russia, a source historically prized for producing alexandrite material with strong color change and attractive bodycolor. The combination of its size, cushion outline, and mixed brilliant faceting yields lively scintillation and a distinctive visual character that is rare in stones of this carat weight.

For buyers who appreciate technical grading and origin based value, several points underscore why this alexandrite merits attention. The clarity grade slightly included at eye level communicates realistic, trade standard expectations for natural alexandrite, indicating inclusions are present under magnification but are not disruptive to face up appearance when set. The intense color intensity is a primary driver of value in alexandrite, because collectors and connoisseurs prize the strength and saturation of the day to night color change above many other attributes. Russian provenance further enhances desirability, as classic Russian alexandrite typically exhibits a balanced, clean color shift and tight, saturated hues that appeal to educated buyers and collectors. The excellent polish and careful mixed brilliant cut optimize light return and color expression, so the gem presents well across viewing conditions, and the fact that this stone is natural and unenhanced supports long term value retention relative to treated or laboratory modified material.

From a custom jewelry perspective this alexandrite is especially well positioned for bespoke settings, because its cushion shape and the exact dimensions translate into predictable mounting requirements and design directions. The length and width make it an attractive center stone for delicate to medium scale rings, a refined focal point for pendants, or an elegant element in a three stone composition, while the 3.23 millimeter depth contributes to stable pavilion proportions that preserve face up color saturation without excessive table darkness. The mixed brilliant faceting pattern combines compact crown faceting for color dispersion with a pavilion arrangement that supports lively brilliance, which means designers can choose either open settings to maximize light interaction or protective bezels to emphasize the gem’s color while securing it for everyday wear. Given alexandrite’s hardness at approximately 8.5 on the Mohs scale, this stone is durable enough for rings with proper protective design, and the cushion outline reduces vulnerability at corner points relative to sharp corner cuts, making it a practical and attractive choice for commissioned jewelry.
