1.62 Ct.Tw.Total Carat Weight Alexandrite Pair from Ceylon (Sri Lanka)

This exceptional matching pair from The Natural Gemstone Company consists of two transparent oval alexandrites weighing 0.83 carats and 0.79 carats respectively, each cut to highlight a vivid color change from greenish blue to purple. The measurements are 6.72 x 4.82 x 3.40 mm and 6.61 x 4.84 x 3.51 mm, and both stones feature a mixed brilliant cut, excellent polish, and a clarity grade of very slightly included evaluated at eye level. Unlike many market alternatives that are either heavily treated or synthetic, these alexandrites are completely natural with no enhancement, and they come from the classic and highly respected mining region of Ceylon Sri Lanka. Where other stones might offer only one desirable attribute, such as color or clarity, this pair balances transparency, vivid color intensity, and a precise cut, making them rare in the current market. Buyers who compare common commercial alexandrites will notice that many specimens sacrifice brightness for deep saturation or accept heavy inclusions to achieve color, whereas this pair stands out for delivering both lively optical performance and natural authenticity.

What gives these alexandrites an unmistakable signature are the unique inclusions embedded in each stone, features that act like a mineral fingerprint and that aficionados use to distinguish natural Ceylon material from synthetics or treated stones. Under careful observation the gems display delicate needle like rutile silk that threads through the body of each stone, lending a subtle silky sheen that softens reflections and deepens the body color in certain lighting. Scattered along those fine silk threads are tiny crystal inclusions and minute platelets that catch light as pinpoints, creating a constellation effect that shifts with viewing angle. Growth zoning presents as faint banding patterns that align with the oval shape and the mixed brilliant facets, and on some viewing axes two phase inclusions reveal themselves as minuscule cavities with trapped liquid and gas, evidence of formation under natural geological conditions. These combined inclusions create a layered internal landscape, they diffuse light selectively and they are responsible for the particular way these alexandrites converse with different light sources, producing a signature color response that is irreproducible in lab grown or heavily processed alternatives.

The practical advantage of these inclusions extends beyond mere identification, they actively enhance the gem wearing experience and the value proposition compared with other market options. The mixed brilliant cut has been chosen to work with the internal features, directing light through the silk and tiny crystals so that the greenish blue becomes lively and transparent in daylight and the purple registers as saturated and velvety in incandescent or warm light. Many commercially available alexandrites set into jewelry suffer from either a dull, muddy appearance due to poor cutting or from too many large inclusions that interrupt light flow. By contrast these stones are remarkably transparent for their grade, with the very slightly included clarity evaluated at eye level meaning the inclusions are visible to a trained eye or under magnification, while to everyday wearers the gems present as clean and radiant. The excellent polish ensures facet junctions are crisp, maximizing brilliance and color change, and because there has been no enhancement the color and structural features are stable and durable, offering long term enjoyment and collectible integrity.

For buyers seeking a superior alexandrite pair the comparison is clear, these Ceylon stones outperform many market alternatives in terms of natural character, balanced optical performance, and investment quality. Synthetic stones may show perfect clarity but they lack the fingerprint of nature, and treated stones can mimic color while sacrificing provenance and stability, whereas these alexandrites deliver authentic inclusion patterns, vivid color intensity, and excellent craftsmanship in cutting and polishing. Whether you are a collector who values diagnostic internal features, a jeweler who needs matched stones with stable, repeatable color change, or a private buyer seeking a statement piece that pairs rarity with wearability, these gems represent a rare convergence of attributes. The Natural Gemstone Company stands behind the provenance of this pair, and we encourage prospective owners to consider how the distinctive needle silk, minute crystals, growth zoning, and two phase evidence not only confirm natural origin but create an unmistakable signature that will be recognized and appreciated by connoisseurs and future generations.
