17.47 Ct. Purple Amethyst from Brazil

This exceptional transparent amethyst from The Natural Gemstone Company presents a rare combination of size, cut quality, and pure natural color, making it an outstanding choice for collectors and designers alike. Weighing 17.47 carats, and measuring 18.40 x 15.25 x 10.82 mm, this oval faceted gem has been fashioned with a mixed brilliant cut to balance scintillation and depth of color. The clarity has been evaluated at eye level as very very slightly included, which in practical terms means the stone presents as essentially eye clean to the unaided viewer while retaining the natural internal character that confirms its authenticity. The color intensity is vivid, and the polish is excellent, resulting in a gem that delivers bold visual impact without any enhancement. Originating from Brazil, this amethyst retains the geographic pedigree associated with some of the finest purple stones available on the market.

Color is the primary attribute that will make this gemstone stand out in any jewelry setting, and this amethyst is exemplary in that regard. The vivid purple saturation is evenly distributed across the table and crown, producing a rich, velvety tone that reads strongly in both bright daylight and softer indoor lighting. The mixed brilliant cut was chosen to enhance both fire and face up color, with carefully proportioned facets that allow light to penetrate and return in flashes, while deep pavilion angles support the stone body color. Because amethyst exhibits pleochroism to some extent, viewing the stone at different angles reveals subtle shifts in purple hues, which adds a dynamic quality to rings, pendants, and statement earrings. Set in a solitaire ring, the size and saturation of this 17.47 carat amethyst will dominate the composition, providing a focal point that reads as both luxurious and wearable. When set with complementary metals, such as warm yellow gold that intensifies the richness of purple, or cool white metals that create a modern contrast and allow the gem to read with crisp brilliance, the stone will remain visually commanding.

Beyond its spectacular color, the gemological attributes of this amethyst support its desirability for discerning buyers. The very very slightly included clarity grade at eye level indicates minimal internal features that do not detract from beauty, and in fact help to certify the stone as natural and untreated. The excellent polish contributes to strong facet crispness, which is critical for imaging and for maximizing return of light in jewelry settings. The mixed brilliant cut balances a larger table face up area with a faceted crown arrangement, producing an engaging play between color and sparkle. On the matter of durability, amethyst is a quartz variety with a Mohs hardness of seven, making it suitable for everyday wear when set thoughtfully. For rings and other pieces subject to wear, we recommend protective settings such as low profile prongs or bezel accents to protect the girdle and pavilion, while still allowing sufficient light entry through an open gallery to showcase the stone color.

Provenance and treatment status are essential considerations for educated buyers, and this amethyst performs strongly in both areas. Sourced from Brazil, the stone benefits from a region known for producing high quality amethyst with consistent color distribution and clarity. Importantly, the stone is natural and unenhanced, which preserves both its market value and its appeal to collectors who prioritize untreated gemstones. For clients seeking documentation, The Natural Gemstone Company is happy to assist in arranging independent gemological reports that detail weight, dimensions, cut characteristics, clarity observations, and origin when available. From an investment perspective, this combination of significant carat weight, vivid color, natural origin, and excellent cutting and polish makes the stone a distinctive acquisition. If you would like to explore setting options or request additional lighting images and angles to evaluate face up color and brilliance, our specialists at The Natural Gemstone Company are available to advise on metal choices, mounting styles, and custom design considerations to ensure that this purple amethyst becomes the centerpiece it deserves to be.
