6.81 Ct. Yellowish Green Prasiolite from Madagascar

This exceptional prasiolite offered by The Natural Gemstone Company is a transparent 6.81 carat round, with precise dimensions of 12.79 by 12.74 by 7.24 millimeters, presented in a mixed brilliant cut that optimizes both scintillation and depth. The gem exhibits an intense yellowish green hue, an excellent polish, and a clarity graded as very very slightly included at eye level, which means the stone appears clean to the unaided eye with only minute inclusions visible under magnification. Originating from Madagascar and enhanced by stable heat treatment, this prasiolite represents a desirable balance of natural provenance and accepted enhancement practice, as heat treatment is the standard method for producing the most attractive green tones in quartz. The mixed brilliant cut yields strong light return from the crown and pavilion facets, producing lively brilliance and a pleasing face up presence for a stone of this size. For an educated buyer, the combination of a large 6.81 carat weight, intense color saturation, tight proportions, and excellent polish delivers a high value proposition, particularly because sizable, transparent prasiolites with strong, evenly distributed color are uncommon in the market.

When designing a custom piece to showcase this prasiolite, consider settings and companion stones that enhance its yellowish green character while maintaining a refined aesthetic. A white metal setting such as platinum or white gold will provide crisp contrast and emphasize brilliance, making small near colorless diamonds ideal for a classic halo or tapered shoulder accents that increase perceived size and sparkle. For a warmer, tonal composition, yellow gold or rose gold will harmonize with the yellow undertone, and small champagne diamonds or golden sapphires will create a sophisticated, sunlit palette. For a striking complementary contrast, pair the prasiolite with medium to deep purple amethysts, which will accentuate the green through color contrast and create visual drama in a three stone ring or pendant. Given quartz hardness of seven, this prasiolite is suitable for rings, pendants, and statement earrings when set with protective bezel or secure prong designs, and with routine care it will retain its beauty for years.
