19.39 Ct.Tw.Total Carat Weight Brown Smoky Quartz Pair from Brazil

This matching pair of smoky quartz from The Natural Gemstone Company comprises two transparent drops, weighing 9.23 carats and 10.16 carats respectively. Each stone is fashioned in a refined fancy drop shape, with dimensions of 20.30 x 9.80 x 9.80 millimeters for the 9.23 carat example, and 20.10 x 10.40 x 10.40 millimeters for the 10.16 carat example. Both stones present a consistent, intense brown tone, and are described as having an impressive transparency that allows light to traverse the pavilion and crown evenly. Clarity is graded as very very slightly included when evaluated at eye level, indicating inclusions are minimal and do not interfere with visual performance in typical jewelry settings. The gemstones are untreated, with no enhancement, and they have been given an excellent polish by skilled lapidaries, resulting in crisp facet junctions and a clean table surface. The pair is well matched for color intensity, cut style, and overall finish, making them suitable for a coordinated set such as a pair of drop earrings or a matched pendant and accent piece.

From a gemological perspective these smoky quartz specimens exhibit the key physical attributes associated with natural quartz, which inform durability and handling considerations. Quartz has a Mohs hardness of seven, providing good resistance to everyday abrasion while requiring reasonable care to avoid sharp impacts. Typical optical constants for quartz include a refractive index range around 1.544 to 1.553 and a specific gravity near 2.65, values that are consistent with the observed light performance of these stones. The drop cut employed emphasizes elongated facets that guide light along the length of the stones, producing depth and controlled dispersion without excessive brilliance that would mask the brown hue. Facet symmetry and proportional cutting are evident in both pieces, and the matching process accounted for weight, outline, and pavilion depth to ensure a harmonious pairing. These characteristics make the pair versatile for settings that secure the stones at the top of the drop and allow the lower pavilion to display its geometry, such as prong or bezel mountings designed for forward light transmission.

The Natural Gemstone Company sources these smoky quartz gemstones from Brazil through established partners and direct relationships with local suppliers. Our sourcing approach emphasizes traceability, and documentation accompanies each lot to confirm mine origin and transaction history. Suppliers are vetted against a Supplier Code of Conduct that requires compliance with applicable labor laws, fair compensation practices, and workplace safety measures. Environmental stewardship is an integral element of our sourcing policy, and we prioritize partners who implement progressive land management practices, minimize ecological disturbance, and undertake reclamation where mining activity has occurred. Where available, independent on site visits and third party audits are conducted to verify operational practices, and we maintain records that support chain of custody tracking. These measures are designed to reduce risk in the supply chain and to provide confidence that the gemstones were produced under conditions that respect both people and place. The absence of enhancement further supports a direct narrative from Brazilian deposit to finished gem, preserving the natural characteristics of each stone.

Care instructions and application guidance are provided to preserve the appearance and integrity of the pair over time. Routine cleaning may be performed with warm water, mild detergent, and a soft brush, followed by gentle drying with a lint free cloth. Ultrasonic cleaning is generally acceptable for well cut and stable quartz, however caution is advised if settings include treated metals or fragile mountings. Avoid exposure to strong chemicals and prolonged high heat to maintain optimal appearance, and remove jewelry for activities that risk severe impact. For custom projects The Natural Gemstone Company can provide detailed measurements, high resolution images, and matching services to assist jewelers and designers in planning settings that respect the stones mass and profile. We make available supporting documentation that outlines the measured dimensions, carat weights, clarity observations, and origin statement, enabling informed decisions for certification or appraisals. Our continued commitment is to provide transparent, accurate information about each gemstone so that the attributes described here can be relied upon in design, valuation, and long term enjoyment.
