25.26 Ct.Tw.Total Carat Weight Amethyst Pair from Bolivia

This matched pair of amethysts offered by The Natural Gemstone Company presents a rare combination of weight, clarity, and color uniformity that will appeal to educated collectors and designers. Individually the stones weigh 12.49 carats and 12.77 carats, with dimensions of 19.16 x 15.17 x 8.65 millimeters and 19.06 x 15.08 x 9.03 millimeters respectively. Both are fashioned in a refined fancy shape and executed with a step cut that emphasizes broad, clean facets. The finish is described as an excellent polish, which enhances the amethysts’ transparent, vitreous luster without introducing surface disturbance. Clarity is graded at very very slightly included when evaluated at eye level, meaning both stones are essentially eye-clean with only minuscule internal features visible under magnification. Color is judged to be vivid in intensity, a key determinant of desirability for amethyst, and there is no evidence of enhancement, confirming that these are natural, untreated Bolivian amethysts. The combination of substantial carat weight, consistent dimensions, and uncompromised transparency makes this pair particularly suitable for high-end matched settings or for collectors seeking museum-caliber matched stones.

From a gemological perspective, several factors here signal premium quality to the informed buyer. Color, the single most important attribute for amethyst, is described as vivid, indicating strong saturation and a balanced hue without brown or gray modifiers that can depress value. Bolivian origin is notable because Bolivian amethysts, particularly those from historically significant deposits, are known for producing deeply saturated purples with occasional red flashes and an appealing tonal range. The step cut chosen for these stones is deliberate and advantageous; step cuts emphasize color and clarity over scintillation, creating broad planes that allow the viewer to appreciate the depth and uniformity of the purple. Inclusions are minimal at the eye level grading of very very slightly included, which in practical terms means the pair will present as clean and bright when set, an important consideration for earrings or a matched pendant pair. The close correspondence of dimensions and the minor 0.28 carat difference in weight are within the tolerances that connoisseurs accept for matched pairs and they reflect precise cutting and attention to symmetry.

When comparing this pair to famous matched gemstone pairs in the world, the qualities that define collectability and institutional interest become apparent. Renowned paired gemstones held in museum and private collections are often prized for their natural color purity, provenance, and the absence of enhancement, attributes shared by these Bolivian amethysts. Leading jewelry houses and historic suites have long sought matched pairs that demonstrate uniform hue, consistent saturation, and superior clarity, all of which are present here. While the world’s most famous pairs may command premiums because of provenance or historical provenance, from a strictly gemological standpoint this set aligns with the technical standards those pieces embody: natural origin, vivid saturation, eye-clean clarity, and exemplary cutting and polish. For buyers who compare stones side by side, the step cut’s disciplined facets produce the controlled flash and color windows that experts look for in matched pairs intended for high-end mounts, and the absence of treatment increases long-term value and desirability. In short, this pair performs like the kinds of matched amethyst pairs that have been selected historically for major commissions and museum-grade jewelry, while offering the additional advantage of contemporary cutting precision and excellent polish.

For the designer or collector engaging with The Natural Gemstone Company, these amethysts represent a rare opportunity to acquire a matched pair of significant carat weight that is both technically excellent and visually compelling. Their Bolivian origin and untreated status mean they are attractive to buyers who prioritize natural provenance and transparency in treatment disclosure, and their step cut and matching proportions make them versatile for a range of settings, from elegant drop earrings to a paired brooch design or a bespoke trilobe pendant when paired with a complementary center stone. We recommend evaluation in the intended setting to appreciate how the step facets interact with metal and light, and our team can provide additional magnified images, matching reports, and mounting recommendations. Care considerations are straightforward; amethyst is a durable variety of quartz and should be protected from prolonged exposure to high heat and harsh chemicals, and routine cleaning can be done with warm soapy water and a soft brush. If you would like to proceed, The Natural Gemstone Company can assist with independent lab documentation, custom design referrals, and secure shipping options. These two Bolivian amethysts combine provenance, untreated natural beauty, and matched technical quality, making them an outstanding acquisition for the informed buyer seeking a museum-quality matched pair.
