14.12 Ct. Amethyst from Brazil

This transparent 14.12 carat asscher octagonal amethyst from Brazil presents an immediate impression of size and refined geometry, with exact dimensions of 14.01 by 13.77 by 10.96 millimeters. The stone has been fashioned in an asscher cut, which translates for the educated buyer into a stepped pavilion and crown structure, concentric facets, and the hallmark square octagonal outline that reads as both vintage and modern. The color of the gem is described as medium intense purple, a tone that is deep enough to convey classic amethyst character while remaining bright and lively under a variety of lighting conditions. The clarity grade is eye clean evaluated at eye level, which means there are no visible inclusions to the unaided eye for typical viewing distances, and the polish is graded excellent, ensuring crisp facet junctions and lively reflection across the table and step facets. Enhancement is none, this gem is natural and untreated, and its provenance is Brazil, a long established and respected source for high quality amethyst material. As representatives of The Natural Gemstone Company, we prioritize transparent, verifiable information, and these specifications are intended to give a clear, technical understanding of what this particular stone brings to a collector or client.

The asscher cut chosen for this amethyst plays a crucial role in how the stone displays color and light, and it is worth understanding the mechanics if you are assessing value. Step cuts like the asscher use larger, linear facets that emphasize clarity and color rather than sparkle, so an eye clean grade is especially desirable in this style because there are broad, open surfaces that act like windows into the gem. The octagonal outline and concentric pavilion steps create a hall of mirrors effect, producing broad flashes of purple and secondary lighter zones that shift as the stone moves. The proportions, with a substantial depth relative to the table and crown, allow the medium intense color to saturate the body of the gem evenly without appearing dark or dead. Excellent polish means that each facet face is smooth and reflective, which maintains contrast between the step layers and enhances the perceived richness of the purple. For a buyer who values wearable scale, this 14.12 carat size is large enough to be a prominent solitaire in a ring, pendant, or bespoke cocktail piece, while the asscher cut respects the gem’s crystalline origin and yields an elegant, architectural presence.

Inclusions in natural gemstones serve as fingerprints of origin and formation, and in this amethyst they are part of the stone’s story and appeal. Although this example is eye clean when evaluated at eye level, microscopic examination may reveal internal features typical of quartz group minerals, such as fine rutile needles, small mineral crystals, growth zoning, and healed fracture planes. These features are not defects in the same sense that surface abrasions are, rather they are microscopic records of the crystal growth environment and subsequent geological history. For the discerning collector, such inclusions can be extremely valuable as confirmation of natural origin, and they help laboratories, cutters, and gemologists trace material back to specific regions and mining conditions. Because this amethyst has not been enhanced, the natural inclusion pattern, color zoning, and internal characteristics are intact, which further supports provenance claims and the integrity of the gem. When set by a skilled jeweler, these internal features remain hidden to the casual viewer, while still providing the educated owner with reassurance of authenticity and natural beauty.

From a valuation and use perspective, this Brazilian asscher amethyst represents a compelling offering for buyers who prioritize natural origin, optical clarity, and classic cutting style. Large, eye clean amethysts are less common than smaller samples, and the combination of 14.12 carats, excellent polish, and medium intense natural purple color is attractive for both collectors and designers aiming to create statement pieces with longevity. The asscher cut minimizes the need for aggressive color enhancement because it works with the gem’s innate color distribution, and with no enhancement applied to this stone, you are acquiring material in its natural state. Practical considerations include selecting a mounting that protects the gem’s pavilion and corners, as the octagonal geometry benefits from secure bezel or prong settings with corner reinforcement, and avoiding exposure to sudden intense heat or chemical cleaners to preserve the untreated color. At The Natural Gemstone Company we can provide additional photographic angles, video, and magnified images for appraisal or design purposes, and our team is available to discuss mounting options and secure shipping. For a buyer who seeks a combination of technical excellence, natural authenticity, and distinctive presence, this asscher octagonal amethyst is a rare and satisfying choice.
