117.00 Ct. Yellow Quartz from Madagascar

One beautiful transparent 117.00 carat oval yellow quartz from Madagascar makes a statement that few other gems in this price and size range can match, The Natural Gemstone Company. Measuring 32.00 x 27.53 x 20.77 millimeters, this substantial oval commands attention both as a collector specimen and as the centerpiece of a high end custom design. The mixed brilliant cut combines a faceting strategy that balances scintillation and overall brilliance, while the excellent polish delivers a glass like surface that captures and returns light with exceptional clarity. With a clarity grade of very slightly included at eye level, the stone retains pristine transparency to the unaided eye, setting it apart from many commercial quartz pieces that appear cloudy or heavily included. The light yellow hue is elegant and versatile, soft enough for everyday wear yet luminous enough to read as refined and precious in more formal applications. Importantly, this quartz is natural with no enhancement, which enhances provenance and long term value compared with treated alternatives.

What gives this oval yellow quartz its unmatched sparkle is an interplay of natural crystal quality and expert cutting geometry, the quartz crystal lattice allows light to penetrate deeply because of its high transparency and uniform internal structure, when light enters the gem the mixed brilliant faceting creates multiple internal reflections that concentrate and return light through the crown, the carefully shaped crown and pavilion facets are calibrated to maximize light return rather than simply increasing size, this results in intense flashes of bright white brilliance and lively scintillation, the large table and well proportioned facets generate broad flashes while the smaller brilliant facets create rapid pinfire scintillation that animates the gem when it moves. Compared with simple step cuts that emphasize color at the expense of sparkle, the mixed brilliant pattern offers the best of both worlds, it preserves the stone s natural pale yellow color while delivering a dynamic play of light, the very slightly included clarity means there are few interruptions to light paths, so light bounces internally longer before exiting, producing a depth and persistence of sparkle that casual observation often mistakes for higher dispersion. The excellent polish is crucial, because any microscopic surface abrasion scatters light and dulls brilliance, this piece was finished to a degree that allows maximum refraction and reflection at every facet junction, the result is a luminous presence that reads as crisp and lively even under soft or diffuse lighting, a quality that many larger gemstones fail to maintain when they are poorly cut or over polished.

When you compare this exceptional Madagascar quartz to other yellow gems on the market, its advantages become clear, relative to citrine that is often mass produced and heat treated, this natural, untreated example offers greater collector interest and a purer story of origin, relative to yellow topaz and yellow sapphire which can command much higher prices per carat, this quartz delivers impressive scale and visual impact at a fraction of the cost, the warmth of the pale yellow tone reads elegant and versatile alongside both white and yellow metals, and the mixed brilliant cut gives it more life than many similarly colored stones that are simply large but visually dull. Against diamond, this quartz can never match hardness or dispersion, but it outperforms many diamonds in raw visual size and presence for the same investment, and the absence of enhancement means connoisseurs will appreciate the stone s natural state and stable value. For jewelers seeking a memorable center stone, for designers who want a bold statement without the luminous austerity of higher dispersion gems, and for collectors who prize provenance, clarity, and artisanal cut quality, this oval yellow quartz is a rare and compelling option. The Natural Gemstone Company is proud to present this fine example of Madagascar quartz, a gem that combines natural beauty, expert cutting, and honest value into a piece that sparkles in ways few others do.
