1.03 Ct. Alexandrite from Brazil

This exceptionally transparent 1.03 carat emerald cut alexandrite measures 6.14 x 4.82 x 3.62 mm, and presents a distinctive greenish to purplish color change that is the hallmark of top quality alexandrite. The emerald cut with its large table and step facets produces a sophisticated play of light and color, allowing the stone to show its green phase clearly in daylight and its purplish phase under incandescent or warm light. This piece carries an eye level clarity grade of very very slightly included, which means it reads as clean to the unaided eye while retaining the natural internal features that are diagnostic for origin and authenticity. The polish on this gem is excellent, giving crisp facet junctions and strong lustre that enhance the color change effect. There has been no enhancement to this stone, making it a natural, untreated alexandrite from Brazil, and that origin is known for producing material with impressive color saturation and pronounced change, qualities that educated buyers will recognize and value.

From a connoisseurs perspective, several technical attributes of this gem drive its value. The weight of 1.03 carat sits at an attractive threshold where alexandrite rarity and wearability intersect, and the proportions of 6.14 x 4.82 x 3.62 mm yield a face up presentation that appears slightly larger than the numeric weight might suggest because of the elongated emerald cut table. The very very slightly included clarity grade evaluated at eye level indicates that there are only minor inclusions, none of which detract from the visual impact, and these subtle inclusions can actually serve to confirm natural origin under gemological examination. The intense color intensity reported for this piece is a major factor, because alexandrite value is driven more by the strength and quality of the color change than by carat weight alone. The excellent polish ensures light is returned efficiently from the step facets, so the color shift reads cleanly and without the haze that can occur in poorly finished stones. The fact that this alexandrite is untreated further elevates its desirability for collectors and buyers who prefer natural, unenhanced gemstones, and Brazilian provenance adds an appealing narrative and market recognition that supports long term value.

When planning a custom piece around this emerald cut alexandrite, consider designs that both protect the stone and showcase its transformative color. A classic halo of small round brilliant diamonds set in platinum or white gold will provide bright contrast and immediate visual spark that helps the green phase pop in daylight while offering a neutral backdrop for the purple phase under warm light. If the goal is to emphasize the purplish tones, a rose gold mounting will warm the overall palette and gently amplify the purple, making the gemstone read more towards its evening color. Conversely, a yellow gold setting will enrich the green phase and lend a vintage character that complements Brazilian origin material. For side stones, tapered baguettes or emerald cut diamonds maintain a geometric lineage with the center emerald cut, preserving the refined step cut aesthetic and preventing color competition. For a more colorful statement, consider pairing small pink sapphires or padparadscha tone sapphires to accentuate the purple phase, or use green tsavorite garnets as subtle counterpoints to the green phase, taking care to arrange the colored accents so they frame rather than overpower the alexandrite. In a three stone layout, selecting slightly smaller emerald cut or trillion cut side stones will visually lengthen the hand and keep the alexandrite as the focal point. For everyday wearability, a bezel setting can protect the delicate corners of the emerald cut, though an open prong setting will maximize light entry and enhance the color play.
