22.74 Ct. White Cabochon Quartz from Madagascar

This piece is a transparent 22.74 carat white quartz, cut into a cushion outline with dimensions 22.58 x 14.93 x 8.47 mm, originating from Madagascar and presented by The Natural Gemstone Company. The cutting style is a cabochon, characterized by a smooth, convex dome and a carefully controlled girdle to maintain symmetry across the rectangular cushion form. Color intensity is colorless, and clarity is graded as very slightly included, evaluated at eye level. No enhancement has been applied to this crystal, and the surface exhibits an excellent polish that delivers a clean, vitreous finish. The measured proportions emphasize the length to width ratio typical of a cushion cabochon, and the generous depth of 8.47 mm yields a substantial presence without compromising optical transparency.

From a lapidary perspective this cabochon reflects disciplined material preparation and finishing protocols. The preform preserved the natural crystal habit, allowing the cutter to retain mass while defining the cushion silhouette and softened corners. Grinding progressed through successively finer wheels and abrasives to remove rough plane distortions, and final smoothing was achieved with fine silicon carbide and felt laps. The final polish employed a cerium oxide or equivalent oxide slurry to develop the high gloss and to minimize micro abrasions that scatter light. Quartz has a refractive index range near 1.544 to 1.553, with a low birefringence around 0.009, so the cabochon form is optimal to present even light transmission without significant anisotropic color effects. The excellent polish and controlled dome curvature reduce surface reflections that could otherwise mask internal clarity, enabling the stone to appear lucid and gemlike in both ambient and directed lighting.

Clarity assessment describes the stone as very slightly included when observed at eye level. In quartz this typically corresponds to faint feathers, tiny healed fissures, or minute mineral inclusions that do not materially interrupt light transmission. Those internal features are distributed sparsely and remain unobtrusive against the otherwise clear matrix, contributing to authenticity and natural origin without detracting from visual appeal. The cabochon format provides forgiveness for the occasional internal feature because the smooth dome diffuses light, softening apparent contrasts and producing a uniformly luminous field. The absence of enhancement ensures the internal structure is native, and it preserves long term stability from exposure to heat and light. For care, routine cleaning with warm soapy water and a soft brush is sufficient, and occasional professional re polishing will restore peak surface luster if the stone sustains superficial wear. Quartz rates seven on the Mohs scale, providing reliable resistance to daily wear while accommodating a broad range of mounting styles.

In wearable design this transparent cushion cabochon is exceptionally versatile, translating easily between casual minimalism and formal statement jewelry. In a casual context the gem functions well as a low profile bezel set on a signet or band, where the polished dome integrates with daily dress and resists snagging. For formal applications the generous table and thickness produce a substantial visual anchor when set in a high bezel or gallery prong mount, enabling dramatic solitaire rings, elegant pendant centers, or couture brooches that rely on pure optical clarity rather than color saturation. The rectangular cushion silhouette lends itself to modern architectural settings and to classic Victorian inspired bezels, and the colorless intensity pairs harmoniously with white metals and yellow or rose gold. The Natural Gemstone Company can advise on setting proportions to maintain the cabochon crown to bezel relationship, and we offer bespoke mounting services to maximize both aesthetic impact and wearability. For collectors and designers seeking an unenhanced, well proportioned transparent quartz from Madagascar, this piece presents a rare combination of size, clarity, and lapidary refinement, suitable for both everyday elegance and ceremonious presentation.
