28.79 Ct. Quartz from Madagascar

This is a remarkable transparent lemon quartz from Madagascar, weighing 28.79 carats, presented in an elegant oval shape, with dimensions of 22.65 by 18.32 by 11.72 millimeters, masterfully faceted with a mixed brilliant cut to maximize scintillation and light return, graded eye clean when evaluated at eye level, showing a medium intense color that sits in the very pleasing range of true lemon yellow, and finished with an excellent polish that underscores the stone clarity and brilliancy. This gem is completely natural, with no enhancement, and that fact alone elevates its desirability for collectors and designers who seek authenticity and integrity. At this scale the stone commands presence without appearing garish, and the oval outline allows the color to play differently across the face and pavilion, creating zones of lively citrus among softer, sunlit fields. The Natural Gemstone Company is proud to offer this specimen, because it blends exceptional size, natural color, and superb cutting quality into a single, wearable showpiece.

When you compare the hue and tone of this Madagascar lemon quartz to citrus colored gems from famous localities, subtle but important differences emerge, differences that make this piece stand out. Brazilian citrines, particularly those from the classic Minas Gerais districts, often lean toward a warm golden or honey tone, sometimes with a hint of orange that moves them nearer to Madeira hues. By contrast this Madagascar lemon quartz reads a cooler lemon yellow, with a fresh, lively tone that favors clarity of color over the tawny warmth seen in many Brazilian stones. Sri Lankan yellow sapphires tend to show a richer, more saturated golden yellow due to both their inherent mineral chemistry and typical cutting choices. This Madagascar quartz, with its medium intense color, sits lighter and airier than those sapphires, offering a crisp, citrus clarity that can be dressed up or down with settings that favor modern, minimalist design. If you are comparing to classic topaz from Brazil or Pakistan, those stones can present deeper golden blues or champagne tones after heat treatment. The advantage of this lemon quartz lies in its natural, unenhanced, consistent yellow, which offers the look of sunshine without the sometimes overpowering warmth of more common sources.

Make a second comparison to well known green yellow and greenish yellow gems to better understand the uniqueness of this Madagascar stone. Peridot from Arizona and Myanmar often shows an olive leaning green that can read heavy at certain angles, and demantoid garnets from Russia take the green axis even further into intense vividness, due to their chromium and iron content. This lemon quartz is decisively on the yellow axis, with a tone that remains distinctly lemon even under varied light, rather than shifting green or orange. Lemon beryl and heliodor, seen from sources like Namibia and Brazil, can approach similar tones but they typically present higher refractive indexes and different faceting behaviors that create a harder, more crystal like brilliance. The Madagascar quartz, however, offers a warmer, softer light play that feels more forgiving in everyday wear yet still remarkably lively for its weight and cut. In comparison to yellow zircons from Cambodia and Sri Lanka, which can flash brilliant fire and have a distinct sparkle due to higher dispersion, this quartz offers a more uniform glow and a larger visual presence per dollar, yielding excellent value for someone seeking scale and color without resorting to heat treated or rare species.

Beyond immediate color comparisons, the provenance from Madagascar contributes meaningful context for discriminating buyers who understand geographical distinctions. Madagascar has become known for producing crystals with vivid natural hues and excellent crystal forms, and this lemon quartz carries that regional signature in its clarity and purity of tone. Unlike some stones from heavily mined Brazilian pockets that may require heat treatment to achieve desirable tones, this gem arrives in market ready condition, unenhanced, which preserves both its aesthetic and its potential resale value. The mixed brilliant cut, applied by experienced cutters who understand how to work with quartz, yields an excellent polish and faceting symmetry that accentuate the stone face up, while maintaining a stable tone across the profile. For designers and collectors at The Natural Gemstone Company, the combination of size, origin, and natural color creates an opportunity to craft a standout ring, pendant, or centrepiece that speaks to modern taste while retaining provenance and integrity. If you value a stone that compares favorably in hue and tone to better known gems but offers a distinct lemon clarity and superior value, this Madagascar lemon quartz is an outstanding choice.
