12.83 Ct. Amethyst from Brazil

This 12.83 carat transparent purple amethyst from Brazil is a statement of form and substance, a gem that stands apart from the common offerings you find in many catalogs and jewelry cases. The trillion shape measures 16.03 x 15.87 x 9.94 mm, and its triangular silhouette presents a modern alternative to typical ovals and rounds, offering a dynamic play of light that feels both contemporary and timeless. The medium light color intensity provides a vivid purple that is versatile enough for everyday elegance and refined enough for formal occasions, while the very, very slightly included clarity, evaluated at eye level, gives you an eye clean appearance that maximizes brilliance. With an excellent polish and no enhancement, this natural amethyst preserves the integrity and character that collectors and thoughtful gift givers value most, and The Natural Gemstone Company is proud to present it as an example of honest, high quality sourcing.

When you compare this gem to others on the market, several meaningful advantages become clear. Many amethysts in this price range are heat treated, irradiated, or otherwise enhanced to intensify color, which can be appropriate for some buyers but diminishes the appeal for those who prefer untouched natural stones. Synthetic alternatives may offer consistent color and lower cost, but they lack the provenance and individuality of a natural Brazilian amethyst. Lower grade amethysts often show cloudiness, heavy inclusions, or muted tones that reduce sparkle and presence, and mass market cuts frequently waste potential fire and refraction. By contrast, the trillion cut on this piece is precision executed to return maximum light from each facet, and the excellent polish ensures crisp facet junctions and lively scintillation. The result is a gem that outperforms many similar sized stones that trade on weight alone, delivering both optical performance and honest, unenhanced natural origin.

As a gift, this purple trillion amethyst makes a striking impression that few other stones can match. Its size and triangular shape immediately signal that this is a special selection, not a mass produced accessory, and the purple tone carries a sense of luxury, creativity, and refined taste. For someone celebrating a milestone, a meaningful birthday, an anniversary, or a personal achievement, presenting this amethyst communicates both thoughtfulness and discernment. The gem adapts beautifully to a variety of settings, whether set as a bold solitaire in a ring to catch every eye, suspended as a pendant to swing with light and motion, or mounted in a custom three stone design that contrasts its triangular elegance with complementary shapes. Because this stone is unenhanced and originates from Brazil, it offers authenticity that resonates with recipients who appreciate natural beauty and responsible selection.

At The Natural Gemstone Company we pay close attention to the attributes that matter most when choosing a superior gem, and we bring that same care to every stage from selection to presentation. This amethyst is an exceptional balance of size at 12.83 carats, measured beauty at 16.03 x 15.87 x 9.94 mm, a flattering trillion shape, very, very slightly included clarity at eye level, medium light color intensity, and an excellent polish, with enhancement none, and origin Brazil. For practical wear, choose secure bezel or three prong settings to protect the pointed corners while allowing the facet pattern to shine, and clean with warm soapy water and a soft brush to maintain that polished brilliance. If you are comparing options, consider how this natural, unenhanced specimen will retain value and admiration over time in ways that treated or synthetic stones often do not.
