35.51 Ct. Greenish Yellow (Lemon Quartz) Quartz from Brazil

This 35.51 carat greenish yellow quartz presents a compelling combination of scale and technical refinement, attributes that materially contribute to both its market value and rarity. At 35.51 carats the piece sits well above the typical commercial sizes for lemon quartz, offering a substantial visual presence suitable for a single statement ring or pendant. The dimensions, 27.50 by 22.40 by 11.30 millimeters, indicate a well proportioned outline that allows cutters to allocate weight strategically while preserving optimal pavilion depth for light return. Origin Brazil, heat treated, the material exhibits intense color intensity with a precise greenish yellow hue that reads as lemon under controlled viewing conditions, and an eye clean clarity grade when evaluated at eye level, a clarity characteristic that minimizes the need for additional windowing or masking in the final design. The weight itself elevates rarity, because larger quartz crystals that are suitable for clean, high quality faceting are uncommon, and each additional carat increases the difficulty of achieving an even tone and homogeneous transparency during cutting and finishing.

The cutting and finishing demonstrate deliberate craftsmanship, executed in a faceted style with a checkerboard motif, which has been employed to maximize scintillation across the broad surface plane. The checkerboard faceting produces a lattice of small pavillion and crown facets that break light into numerous, controlled flashes, enhancing perceived saturation without deepening tone, a critical consideration for preserving the lemon character. An excellent polish across all facets ensures minimal surface diffusion, which when combined with the stone s substantial thickness, preserves strong light return and consistent eye clean appearance. Heat treatment has been applied to attain the intense color, and the treatment is stable and industry standard for quartz, offering predictable performance in jewellery settings. For connoisseurs assessing proportions, the balance between table size and pavilion depth was maintained to optimize dispersion and durability, reducing the risk of pressure point damage during setting. The Natural Gemstone Company presents this gem as an example of technical and aesthetic excellence in large format quartz, a specimen that will appeal to professionals who value precise faceting, significant carat weight, and verified origin.
