11.85 Ct. Purple Amethyst from Brazil

This cushion shape amethyst weighs 11.85 carats and presents a clean transparent body that responds to light with clarity and depth. Measuring 16.65 by 14.11 by 9.81 millimeters, the stone carries a balanced presence that suits a variety of design applications. The mixed brilliant cut combines step and brilliant facets to optimize face up brilliance while preserving weight, and the cutting strategy enhances the stone architecture so that pavilion and crown interact to reveal internal color zoning in a controlled and attractive way. Color registers as vivid in intensity, a strong and saturated purple that retains evenness across the table and crown, while the polish is assessed as excellent, producing crisp facet junctions and lively surface reflection. Clarity is graded as very slightly included at eye level, indicating that inclusions are minor and do not detract from the overall aesthetic to a trained observer, and the gemstone has undergone heat treatment as an enhancement to stabilize and intensify tone and saturation. The origin is Brazil, a source long associated with high quality amethyst, and the material carries the provenance that links it to established Brazilian supply chains. Measurements, cut, weight, clarity, color intensity, polish, enhancement, and origin combine to form a comprehensive specification set that supports both appraisal and design planning.

The journey of this amethyst begins in a Brazilian deposit where skilled miners work within established operations to extract gem bearing rock. From the mine site, rough material undergoes initial sorting to separate gem quality crystals from lower grade matrix and fracture filled pieces. Larger, well formed crystals are selected for their color potential and structural integrity, and the chosen crystal for this piece was selected for its combination of saturation and clarity that suggested an ideal balance between yield and optical performance. Transported under controlled logistics to cutting centers, the rough receives a measured evaluation to determine the best orientation for the cut, with attention to preserved weight and to the prevention of internal stress that could affect brilliance. Cutting was executed to a mixed brilliant design to align facet geometry with the natural crystal axes, capturing the vivid color while minimizing wastage. Heat treatment was applied in a controlled manner to enhance hue uniformity and to remove undesirable undertones, a common and established practice for amethyst that yields a stable color enhancement when carried out to industry standards. After treatment, the stone received meticulous pre polishing and final lapidary work to reach an excellent polish grade, and the finished piece underwent trained eye level assessment for clarity, confirming the very slightly included status. Each phase of the process was documented to maintain traceability from rough to finished gem.

When the finished gem entered The Natural Gemstone Company inventory, it was recorded with full specification notes and high resolution imagery to support transparent presentation to designers, gemologists, and private collectors. Our standard handling protocol includes verification of weight and dimensions, confirmation of cut type and polish condition, and notation of enhancement and origin so that the end buyer receives a clear account of what they are purchasing. The Natural Gemstone Company retains chain of custody documentation and a concise provenance record to accompany the stone, noting the Brazilian origin and the heat treatment that was applied. In commercial terms, this amethyst is well suited to a center stone role in a ring or a prominent placement in a pendant or brooch, where its cushion outline and mixed brilliant faceting will provide measured sparkle and stable color. The very slightly included clarity grade allows for confident setting design without the need for extensive masking, and the excellent polish supports strong light return that will stand up to close inspection. For care, standard practices apply, including avoidance of sudden temperature extremes and exposure to harsh chemicals, and regular professional cleaning to preserve the surface brilliance. The heat treatment is stable under normal wear conditions and does not require special handling beyond typical gemstone care.

This account of the stone from mine to market is intended to provide a factual synthesis of its attributes and its route through the supply chain, highlighting the technical decisions that informed its final presentation. The weight, 11.85 carats, and the dimensions, 16.65 by 14.11 by 9.81 millimeters, give a clear sense of scale for design integration. The combined qualities of cushion shape, mixed brilliant cut, vivid color intensity, very slightly included clarity at eye level, excellent polish, heat treatment, and Brazilian origin define both the aesthetic appeal and the material history of the gem. The Natural Gemstone Company provides this information to ensure informed selection and to preserve the integrity of the gem narrative as it moves from the hands of the cutter to the laboratory of the appraiser and finally to the hands of the jeweler or collector.
