18.83 Ct. Prasiolite from Brazil

This is a beautiful transparent 18.83 carat cushion shape green prasiolite from Brazil, presented by The Natural Gemstone Company, and it delivers a rare combination of size, clarity, and cut that is difficult to match in the market. The stone measures 18.24 x 15.19 x 10.73 mm, and its mixed brilliant cut has been executed to maximize scintillation and play of light across its broad table and gently rounded shoulders. At eye level the gem is eye clean, offering an optical purity that allows jewelers to design open settings that showcase the internal brilliance without the need for heavy bezels or protective galleries. The prasiolite displays a light color intensity which reads as a fresh, crystalline green, and an excellent polish that translates into lively reflections and crisp facet junctions. The material has been heat treated, a standard enhancement that is stable and widely accepted by connoisseurs, and represents an ethically sourced piece from Brazilian deposits known for producing clean, attractive green quartz varieties.

When compared to other green gemstones commonly used in fine jewelry, this prasiolite stands out in several key respects. Against emerald, the prasiolite offers superior transparency and greater brilliance, because emeralds of comparable size often contain inclusions and require treatments that affect durability and long term maintenance. Versus peridot, this prasiolite is generally more resistant to surface cleavage and offers a subtler, more versatile green that does not read as overly yellow or chartreuse under different lighting. Compared with green tourmaline and green sapphire, the prasiolite provides exceptional value per carat, making it possible to work in large sizes and intricate designs without the steep cost of true precious greens. The cushion shape with mixed brilliant faceting yields a balance of modern sparkle and classic silhouette that many competitors do not achieve at this scale and price point. For designers and buyers seeking a statement center stone that offers both presence and performance, this prasiolite delivers a combination of visual purity, lightness of color, and accessible luxury that is difficult to find in other species without moving into a much higher price bracket.

From a design and setting perspective the stone is particularly adaptable, and its proportions and cut encourage both contemporary and traditional interpretations. The sizeable 18.24 x 15.19 mm footprint makes it an ideal candidate for a bold solitaire ring, an elegant pendant, or a central piece in a multi stone necklace where its light green tone can act as a calming focal point. The mixed brilliant cut enhances light return along the table and crown, while the cushion outline softens the silhouette, allowing for settings that range from minimal prongs to intricate halos that increase perceived size while maintaining brilliance. The eye clean clarity grade means that open backed settings and low profile mounts work well, and the excellent polish ensures that polishing marks will not distract from the clean reflections that define the gem. Because the enhancement is heat treatment, color stability under normal wear conditions is reliable, and routine care is straightforward compared with more fragile greens. Jewelry professionals will appreciate the ease of setting, the predictable behavior of the quartz matrix, and the way the stone photographs, as its light green hue translates beautifully in both studio lighting and natural daylight.

Color harmony and how a gem complements skin tone is a crucial part of selecting a stone, and the pale green of this prasiolite is unusually accommodating across a broad spectrum of complexions. On fair skin with cool undertones the crystalline green will read as a cool, refreshing accent that enhances porcelain and rose tints, and pairing the stone with white gold or platinum will emphasize the coolness and clarity. On fair skin with warm undertones the light green retains enough warmth to avoid appearing icy, and when set in yellow gold it creates a softly sunlit contrast that brings out gentle golden reflections. For medium skin tones the prasiolite acts as a versatile neutral to soft accent, and it harmonizes well with both warm and cool undertones, making it an excellent choice for pieces intended for everyday wear. Olive skin tones benefit from the stone because the subtle green provides a clear, bright counterpoint that complements natural olive warmth without overwhelming it, and pairing with rose gold or mixed metal settings will create sophisticated, wearable contrast. On deeper skin tones the pale green becomes a luminous highlight that reads as crisp and elegant, and it creates a striking presence when set in bold yellow gold or in a halo that frames the facet pattern. For layered jewelry combinations the prasiolite mixes exceptionally well with diamonds, champagne or cognac stones for warmer palettes, and with aquamarine or light green tourmaline for cooler, monochromatic schemes.
