4.87 Ct. Cabochon Quartz from Brazil

This listing describes a single, transparent lemon quartz, weighing 4.87 carat, and presented in a pear shape cabochon. The gem measures 16.59 x 10.35 x 4.46 mm, and exhibits a medium light color intensity throughout the table and crown areas. The cut is cabochon, with a smooth domed surface and a well formed outline that follows the classic pear silhouette. The polish has been evaluated as excellent, producing a high gloss surface and consistent light reflection across the dome. The origin of this quartz is Brazil, and no enhancement has been applied, ensuring the stone is in its natural state as sourced from its locality. This description and the accompanying images are provided by The Natural Gemstone Company, and they reflect the gem as examined at the time of cataloguing.

Clarity has been assessed at eye level and graded as eye clean, indicating that no inclusions are visible without magnification when the stone is viewed under normal conditions. The transparency is described as transparent, and the cabochon form accentuates the gem’s internal clarity and gentle color tone rather than faceted brilliance. The medium light lemon hue is evenly distributed, producing a delicate pastel yellow that remains subtle under diffused light and gains a brighter, more saturated appearance under direct, high intensity light. The excellent polish enhances surface luster and minimizes the visual impact of any minor natural growth features, allowing the stone to display a clean, unbroken visual field across its curved top.

For design and setting considerations, the pear shape cabochon presents several practical advantages. The stone’s dimensions and shallow depth favor bezel settings and closed back mountings, where the cabochon profile seats securely within metal rims and benefits from protection against knocks and abrasion. When set in rings or bracelets intended for regular wear, the cabochon form reduces the risk of edge chipping that can be more common with faceted girdles, while the overall hardness of quartz provides reasonable durability for everyday jewelry. The subject gem’s weight and size also make it well suited for pendants and statement earrings where the gentle dome can be showcased without the need for extensive faceting to generate sparkle. Mounting choices should account for the stone’s bezel friendly shape and for jewelers to check prong security when prongs are used.

Conservation and provenance notes are straightforward, the stone is natural with no enhancement, and its Brazilian origin is documented as part of the item record maintained by The Natural Gemstone Company. Routine care consists of warm soapy water and a soft brush for cleaning, avoiding ultrasonic or steam cleaners when the mounting or any potential surface treatments are uncertain, although none have been applied in this case. Prolonged exposure to strong chemicals or sustained high heat should be avoided to preserve the stone’s color and surface integrity. For appraisals or custom settings, the provided measurements 16.59 x 10.35 x 4.46 mm and weight 4.87 carat give precise parameters for design planning.
