12.44 Ct. Bluish Green Prasiolite from Brazil

This exceptional 12.44 carat prasiolite from Brazil is a significant and rare offering for the informed buyer, and it is presented by The Natural Gemstone Company with full disclosure of its characteristics. The gem measures 15.48 x 12.61 x 9.40 mm, and its emerald cut with a faceted step design preserves weight while delivering a large, elegant table that showcases the stone's transparent nature and intense bluish green hue. At 12.44 carats, this prasiolite occupies a size range that is uncommon for high quality green quartz, and weight is a primary driver of value in colored gemstones because larger rough material is scarcer and yields fewer gem grade finished stones. The density of quartz allows cutters to retain substantial carat weight while achieving strong face up color, and an emerald cut maximizes visual impact while emphasizing clarity and color saturation, attributes that experienced buyers prize.

In terms of gemological quality, this prasiolite is eye clean at standard viewing distances, which enhances its desirability at this size because internal features are not distracting to the naked eye. The intense color intensity and excellent polish contribute to both aesthetic appeal and market value, with the polish ensuring crisp facet edges and optimal light return for a step cut. This specimen has been heat treated, a well established and stable enhancement used to produce and stabilize prasiolite from Brazilian material, a practice that is commonly disclosed and accepted in the trade. Provenance from Brazil is meaningful to collectors and connoisseurs because Brazilian deposits have a long record of producing consistently attractive quartz material suitable for fine cutting. For designers and buyers considering use in a statement ring or pendant, the substantial 12.44 carat weight offers dramatic presence without compromising wearability, and the emerald cut simplifies secure settings that protect corners and maintain symmetry. The Natural Gemstone Company stands behind the descriptive grading provided, and we welcome inquiries regarding viewing, mounting recommendations, and comparative pricing for similarly weighted prasiolite gems, because weight, cut, color, clarity, and origin together determine the enduring value of a piece like this.
