5.69 Ct. Bluish Green Prasiolite from Brazil

Presented here by The Natural Gemstone Company is a beautiful transparent prasiolite of five point six nine carats, cut into a classic round shape. The gem measures eleven point eight two by eleven point eight nine by seven point three five millimeters, and its faceted mixed brilliant cutting style delivers balanced fire and scintillation. The body color is a bluish green with intense color intensity, a hue that reads richer in direct light and deeper at modest viewing angles. The stone has been heat treated to achieve and stabilize this attractive bluish green tone, a standard and accepted enhancement in prasiolite production. Its excellent polish and well executed facet junctions contribute to a crisp appearance, allowing the stone to display broad flashes and a pleasing depth of color.

Clarity in prasiolite is a pivotal factor for collectors who prioritize optical purity, and this example grades very very slightly included when evaluated at eye level. The inclusions are minimal and do not interfere with its internal reflections, and they are generally restricted to tiny natural features that are nearly invisible without magnification, preserving a clean face up presentation. A mixed brilliant cut is particularly effective with this clarity grade because the arrangement of pavilion and crown facets maximizes light return while maintaining broad flash, producing a balanced interplay between scintillation and overall glow. The excellent polish enhances facet contrast and edge definition, increasing apparent transparency and creating a lively surface that resists haziness under normal wear.

At five point six nine carats and with a diameter of approximately eleven point eight two millimeters across the table, this prasiolite occupies the sweet spot between wearable comfort and dramatic presence. Many collectors and designers seek stones in this size range for solitaire rings, signet styles, and halo settings where the central gem needs to read as the clear focal element from a distance. The round shape and mixed brilliant proportions contribute to a symmetric light pattern, ensuring that the gem reads uniformly on the finger and that its intense bluish green color remains consistent from multiple viewing angles. The depth of seven point three five millimeters provides sufficient pavilion volume to support strong face up color without sacrificing brilliance, which is an important balance for colored gemstones. Shown in hand images the stone clearly commands attention while maintaining elegance, and it will translate exceptionally well into a custom mount that showcases diameter and table area, whether set in yellow gold to warm the tone, in white metal to emphasize saturation, or in platinum for classic durability.

From the perspective of a discerning buyer this prasiolite represents a compelling combination of weight, color, and clarity that is uncommon at comparable price points, because large, transparent examples with intense coloration are less frequently encountered than smaller or paler material. Prasiolite is a variety of quartz historically associated with heat treated amethyst, and Brazilian deposits are known for producing clean, well crystallized rough that responds predictably to controlled thermal enhancement, which is why the origin is relevant to connoisseurs who consider geological provenance part of value. Heat treatment in quartz is a widely accepted practice when fully disclosed, and in this specimen the treatment produces a stable bluish green hue that will retain its character under normal wear conditions, while also being straightforward to document on a gem report or invoice. For buyers focused on long term satisfaction we recommend a secure setting that protects the girdle from knocks, and we advise routine cleaning with warm soapy water and a soft brush to preserve brilliance, avoiding harsh chemicals and extreme thermal shock. A professional evaluation for mounting and insurance is a prudent step for any high quality collector piece, and The Natural Gemstone Company is prepared to supply additional imagery, magnified inclusion photos, and provenance documentation upon request to support appraisal and custom design work. In our experience gems of this size, with very very slightly included clarity and excellent polish, perform admirably as centerpiece stones for statement rings and pendants, and they offer both visual impact and a conservative degree of liquidity for collectors who may later consider reselling or upgrading. We can also assist with optional third party gemological certification, which is often useful for insurance and resale, and we stand behind the accuracy of our descriptions with transparent, documented disclosure of enhancements and origin. Purchasing from The Natural Gemstone Company means access to expert guidance on cut optimization, setting recommendations, and long term care advice to ensure this remarkable prasiolite remains a treasured addition to any collection.
