18.81 Ct. Yellow Citrine from Ceylon (Sri Lanka)

This 18.81 carat transparent yellow citrine from Ceylon Sri Lanka presents a refined technical profile for discerning collectors, with dimensions of 16.69 by 13.89 by 12.21 millimeters and a tailored fancy shape. The stone was cut in a mixed brilliant style, combining a faceted brilliant crown with precision step and pavilion facets to maximize internal light return while preserving the gem tissue. The cutter has maintained balanced proportions and a well controlled table to crown ratio, producing strong scintillation and broad flashes without excessive dark centers. Clarity is graded as very very slightly included when evaluated at eye level, with inclusions minimal and well positioned so as not to interrupt the visual field or compromise structural integrity. Color displays intense yellow saturation, the hue evenly distributed across the body with pleasing warmth and no zonal banding, and the surface finish is of excellent polish, revealing sharp facet junctions and consistent facet symmetry. This citrine has undergone standard heat treatment to enhance color uniformity, a stable and widely accepted enhancement in warm colored quartz that yields vibrant tone while preserving long term stability and durability.

The Natural Gemstone Company sources this specimen through established partners in Sri Lanka with documented chain of custody, and we prioritize traceability, fair remuneration to small scale miners, and environmentally mindful practices at each stage. For the conscious consumer seeking responsible gemstones, this citrine integrates technical excellence with ethical provenance, suitable for projects where material integrity and transparent supply chains are essential. Its size and mixed brilliant faceting make it particularly well suited to bespoke ring or pendant designs that leverage the stone as a focal element, and it responds well to classic prong settings that allow light entry from both crown and pavilion, or to low profile bezel mounts when additional security is preferred. Care recommendations include routine cleaning with warm soapy water and avoidance of thermal shock, consistent with its heat treated status. The Natural Gemstone Company stands behind the gem with detailed documentation and consultation for setting and care, supporting buyers who value both fine craftsmanship and conscientious sourcing.
