98.76 Ct. White Quartz

This is a remarkable, transparent white quartz weighing 98.76 carat, presented in a classical oval outline with dimensions of 31.55 by 26.73 by 21.50 millimeters, cut to faceted precision. The cutting style is faceted, executed in a mixed brilliant cut configuration, which combines a brilliant style crown with a pavilion designed to maximize return of light and internal scintillation. The material evaluates as colorless in color intensity, and clarity is graded as very very slightly included at eye level, which preserves exceptional visual purity and allows clean, lively reflections across the table and crown facets. The polish is excellent, producing crisp facet junctions and highly reflective surfaces, and the stone has received no enhancements, retaining its natural state, with origin reported as unknown. These objective attributes establish the gem as a premium example of large white quartz suitable for collectors and fine jewelry designers who demand both presence and technical quality.

From a faceting and craftsmanship perspective, the mixed brilliant approach used on this piece is particularly effective for a gem of this scale and refractive character. The crown displays a dense array of small, well proportioned brilliant facets that form a subtle checkerboard motif when viewed face up, increasing the apparent surface scintillation and providing a patterned play of light as the stone moves. The pavilion has been calibrated to balance internal flash with depth, producing a three dimensional brilliance rather than a flat mirror effect, and the girdle is even and consistent, enabling secure mounting with minimal risk of optical misalignment. Cutters achieved precise symmetry across the major and minor axes, preserving the classic oval silhouette while optimizing the table to crown relationships that govern light return, dispersion appearance, and overall visual balance in a stone of this mass.

Optically, white quartz offers a bright, lively presentation that differs from higher dispersion gems by emphasizing crisp white light reflection and tonal clarity rather than colorful fire. The material exhibits refractive behavior suited to mixed brilliant faceting, and while quartz has modest dispersion relative to diamond, the meticulously executed facet plan here yields pronounced scintillation and a clean, luminous body color. The clarity grade of very very slightly included at eye level means that any internal features are minor and do not detract from the gem’s visual impact when set in most jewelry orientations. With a hardness suitable for jewelry applications, quartz offers everyday resilience with care, and because this specimen is untreated, its physical and optical characteristics will remain stable over time. For designers, the size and weight invite bold design choices, including open back mountings to maximize light entry, multi prong settings to secure the large oval form, or bespoke halo constructions that accentuate the stone’s colorless purity.

As an exceptional gift option, this white quartz makes a striking statement for someone special who values technical quality and timeless clarity, the substantial 98.76 carat mass delivers immediate visual presence, and the pristine, untreated nature of the gem communicates authenticity and thoughtfulness. The combination of an expertly executed mixed brilliant cut, very very slightly included clarity at eye level, colorless color intensity, and an excellent polish produces a jewel that reads as sophisticated and versatile in multiple design languages, from minimalist, contemporary mountings to more elaborate, heirloom inspired settings. Presented by The Natural Gemstone Company, this gem is offered as a centerpiece that will command attention whether worn or displayed, and we are prepared to advise on setting options and design considerations to ensure the final presentation honors both the technical qualities and emotional significance of the gift.
