0.71 Ct. Alexandrite from Ceylon (Sri Lanka)

When you are searching for a gemstone that brings both rarity and reliability to a custom piece, this Ceylon alexandrite from The Natural Gemstone Company answers that call. This transparent alexandrite weighs 0.71 carat, it is round in shape, and it measures 5.33 x 5.25 x 3.67 mm, giving it a presence that is at once elegant and practical for bespoke jewelry. The gem displays a true color change from green to brown depending on light source, it has intense color intensity, and the mixed brilliant cut balances scintillation with depth so the color shift reads beautifully as the stone moves. Eye clean clarity as evaluated at eye level and an excellent polish mean the surface is free of distracting inclusions and the facets return light evenly, and because there has been no enhancement, what you receive is a natural, untreated example of this coveted chrysoberyl variety.

The round shape and these dimensions make this alexandrite exceptionally well suited to custom designs, because round stones sit securely in a wide variety of settings and translate easily into the classic silhouettes that customers request most often. At just over five millimeters in diameter, this gem is ideal as a center stone for a delicate engagement ring that favors refined proportions, and it also adapts beautifully to three stone rings, cluster pendants, and solitaire studs where a compact but impactful center is desired. The mixed brilliant cut enhances the stone body while preserving the color change, which means jewelers can design settings that play with both sparkle and hue, and the 3.67 mm depth gives enough pavilion to create brilliance while allowing for secure bezel or prong seats without excessively raising the profile.

For clients who care about daily wearability as well as visual drama, the natural hardness of alexandrite makes it a practical choice for rings and bracelets as well as pendants and earrings, and the round outline lends itself to protective bezels when durability is a priority. If the goal is to present the green phase, choose white metals such as platinum or white gold to emphasize cool tones and crisp contrast, and if the goal is to showcase the warmer brown or purple shift, yellow or rose gold will intensify the warmth and give a vintage or romantic character. A halo of small diamonds will visually enlarge the center and add white fire that complements the color change, while tapered shoulders or split shanks can add movement that shows the stone changing through different angles. Because the gem is eye clean and well polished, it benefits from open prong designs that allow light to enter and reveal the color change, but when the piece is intended for heavy daily wear a low bezel or partial bezel offers strong protection without hiding the gem.

At The Natural Gemstone Company we understand that finding a single special stone ends the search and begins the design, and this 0.71 carat round Ceylon alexandrite is crafted by nature to become the focal point of a lifetime piece.
