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

This 10.05 carat transparent greenish yellow quartz, described as lemon quartz, presents in a fancy shape with precise dimensions of 17.08 by 13.51 by 9.55 mm, and it is offered by The Natural Gemstone Company. The stone is faceted with a mixed brilliant cut, combining a faceted crown with a brilliant style pavilion, producing controlled scintillation and an even spread of light across the table. Clarity is graded eye clean at eye level, allowing internal light paths to remain uninterrupted, and color intensity is medium, which yields a lively lemon hue without overwhelming saturation. Heat treatment has been applied to stabilize and enhance the greenish yellow tone, and the excellent polish and careful facet junctions indicate a high level of lapidary skill, with consistent symmetry and proportion that maximize return of both brilliance and subtle dispersion. The cutting technique emphasizes balanced crown angles and pavilion depth, producing strong contrast facets that contribute to visual depth despite the lighter color, and the gem retains full transparency, showing no clouding under standard inspection.

On the Mohs scale this quartz registers a hardness of 7, making it substantially more abrasion resistant than softer gem materials such as feldspars and other commonly used semi precious stones, while remaining softer than corundum which rates 9, and far softer than diamond which rates 10. In practical terms this hardness supports suitability for many types of jewelry, including rings and pendants, provided standard precautions are observed during wear and setting. For everyday durability consider protective settings such as a partial or full bezel to reduce edge impact, and routine maintenance by warm soapy water and a soft brush to preserve the excellent polish. The heat treatment used on this piece from Brazil is stable under normal conditions, but avoid sudden thermal shocks and prolonged exposure to harsh chemicals to maintain color integrity. For connoisseurs who value technical refinement, this lemon quartz combines accurate proportions, superior polish, and eye clean clarity in a sizable 10.05 carat example, making it a technically interesting and wearable choice from The Natural Gemstone Company.
