0.71 Ct. Alexandrite from Brazil

If you have been searching for a single gemstone that can complete a bespoke engagement ring or become the treasured heart of a collector grade piece, this alexandrite from The Natural Gemstone Company answers that search with confidence, clarity, and color. This beautiful transparent 0.71 carat oval alexandrite offers one of the most desirable combinations for custom work, a vivid color intensity and a dramatic color change that moves from a deep emerald green in daylight to a rich purplish red under incandescent light, showcasing the rare magic that defines true alexandrite. Its Brazilian origin and the fact that it is untreated and unenhanced add an important layer of provenance and authenticity, meaning the gem you choose today will be the same natural marvel for generations. As a salesperson and gemstone specialist I recognize that many clients are looking not just for beauty, but for a statement of lasting value and personal meaning, and this stone delivers both.

The stone s measurements are ideal for custom design, with an oval shape that measures 6.58 x 4.82 x 2.84 mm and a mixed brilliant cut that maximizes sparkle while preserving color depth. The oval silhouette is one of the most versatile shapes for custom jewelry, because it elongates the finger when set in a ring, offers a larger face up appearance relative to its weight, and lends itself to many setting styles from classic four prongs to elegant bezels, from single stone solitaires to diamond halos and three stone designs. At 0.71 carat the gem sits perfectly for clients who want an understated center stone that still commands attention, and the mixed brilliant cut provides lively scintillation that draws the eye to the stone s color change. The clarity is evaluated as very very slightly included at eye level, meaning inclusions do not distract from the gem s beauty when set, and the excellent polish ensures smooth facets that reflect light beautifully and reduce the need for any additional finishing.

What makes this alexandrite especially compelling for custom work is the vividness and reliability of its color change, combined with the practical proportions and excellent cutting. In daylight the lush green presents as a fresh and modern statement when paired with white gold or platinum, while in warmer indoor light the purplish red becomes intimate and romantic when set in yellow or rose gold, creating two distinct moods within a single jewel. The mixed brilliant cut was chosen to balance brilliance with color saturation, so the pavilion and crown facets work together to show both sparkle and the gem s deep tones, and the excellent polish helps the color transition read cleanly across different environments. The 6.58 x 4.82 mm table gives a consistent platform for jewelers to design precise bezels and prong settings, and the 2.84 mm depth ensures the gem can be set securely without compromising on optical performance. The photographs showing the gem on a hand provide a real sense of scale, confirming that this size is elegantly wearable, ideal for clients seeking a refined center stone that still feels intimate and personal.

When you choose this Brazilian alexandrite from The Natural Gemstone Company you are selecting a piece that simplifies the design process and elevates the final creation, because the gem s proportions and quality reduce uncertainty for the jeweler and inspire bold or subtle designs depending on your vision. For those commissioning an engagement ring the oval form and vivid color change create a uniquely personal symbol, a stone that appears different in the photograph on the day you say yes and in the candlelight that follows. For collectors and connoisseurs the untreated origin and strong color change enhance rarity and long term desirability. We offer guidance on metal choices and settings to complement the stone s green to purplish red character, and we can coordinate measurements and CAD previews to ensure a perfect fit based on the precise 6.58 x 4.82 x 2.84 mm dimensions. Let us help you bring this gem into a finished piece that ends your search, because with its size, shape, cut, clarity and natural color change this alexandrite truly is the ideal solution for custom jewelry that will be worn, cherished and passed down.
