70.84 Ct. Cabochon Rose Quartz from Brazil

This offering from The Natural Gemstone Company is a rare and noteworthy example of large scale transparent rose quartz, presented as a 70.84 carat cushion shaped stone with dimensions of 25.40 x 25.00 x 16.20 mm. Large, transparent specimens of rose quartz are uncommon in the market, where most commercial material appears as massive, translucent, or cloudy pieces. The combination of size, clarity and soft pink hue in this specimen places it well above the typical material encountered in both wholesale and retail channels. For designers and collectors seeking a centerpiece gem that reads as both substantial and delicate, this piece stands out for its balance of presence and subtlety. Provenance from Brazil further supports its geological pedigree, as Brazilian sources have historically produced some of the finest crystallized quartz varieties in the world.

From a cutting and craftsmanship standpoint this gem demonstrates deliberate choices that optimize its intrinsic material properties. The stone has been fashioned into a cushion outline, maintaining soft rounded corners and a balanced table area that preserves face up weight while allowing the stone to read larger in diameter. The sugar loaf cut employed here is a hybrid approach that combines broad, gently sloping facets on the crown with a slightly peaked pavilion arrangement, creating a subdued play of light that emphasizes translucency rather than mirror like brilliance. The cutter has prioritized symmetry across the four quadrant facets visible on the crown, producing an X motif that helps distribute the pale pink tone evenly across the table. Polish quality is excellent, with facet junctions rendered cleanly and with minimal surface abrasion, which allows for maximum light transmission given the material s refractive index near 1.55 and its single refractive nature. Hardness around seven on the Mohs scale and a specific gravity near 2.65 make this stone suitable for many jewelry applications while the cutting choices help protect edges and corners that would otherwise be vulnerable in a large piece.

Clarity evaluation at eye level is slightly included, a grade that is consistent with naturally occurring healed fractures, thin veils and small mineral inclusions typical of large quartz crystals. These internal features are visible only upon close inspection and in many viewing conditions they contribute positively to the character of the gem by creating subtle internal texture and soft scattering of light that enhances the stone s ethereal pink tone. Color intensity is described as light, a delicate pastel pink that is evenly distributed with only minor zoning toward the lower pavilion in certain lighting angles. This gentle color intensity is part of what makes this specimen rare, because large crystals that retain transparency while showing a consistent pink without heavy clouding are less common than strongly milky or opaque counterparts. Importantly, this piece has no enhancement, there has been no heating, irradiation or dyeing applied, which preserves the natural optical features and structural integrity that connoisseurs value. The absence of treatment, combined with Brazilian origin and the documented weight and dimensions, supports its suitability for collectors who prefer untreated natural material.

In terms of practical application and value proposition, this 70.84 carat sugar loaf cushion rose quartz is ideal as a singular focal element for high end jewelry or as a collection piece that demonstrates both gemological interest and aesthetic restraint. The stone will perform particularly well in designs that allow light to enter through the pavilion and escape through a generous table, for example open back bezel settings or pendant designs where the crown is oriented to catch diffuse light. For ring applications, a protective bezel or partial bezel with well engineered prong placement is recommended to preserve the rounded corners and to mitigate impact risk. Given the transparency and the reflective properties achieved by the sugar loaf cutting style, pairing this piece with white metals or a halo of small accent stones can emphasize its pale pink while keeping the overall presentation refined.
