16.05 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This stone is a transparent, GIA certified yellow sapphire, weighing 16.05 carats, presented in a classic emerald cut. The proportions are 15.09 by 11.60 by 8.47 millimeters, dimensions that convey a substantial presence while maintaining refined balance on the finger. The sapphire has been evaluated as eye clean at standard viewing distance, indicating that inclusions do not distract the naked eye. Color falls into a medium intensity yellow range, a clear, warm hue that reads as sunny citron with a slightly buttery undertone in daylight, and the cutting and excellent polish produce crisp step facets and a broad faceted table. Importantly, the gem is natural and untreated, with no enhancements, and its documented origin is Ceylon, Sri Lanka, a source with a long established reputation for fine sapphires. The GIA certification confirms the gemological identity and the stated attributes, supplying an independent report that accompanies the stone.

The emerald cut is a deliberate choice for a gem of this quality and character, because its step facet arrangement emphasizes transparency, color distribution, and clarity rather than scintillation alone. The large table and parallel facets create a hall of mirrors effect that showcases the internal depth and the stone color in graduated zones, producing visual elegance and architectural presence. For settings, the stone adapts well to both solitaire and multi stone designs, performing particularly well as a signature center stone in a ring that favors measured, geometric lines, or as a refined focal point in a bespoke pendant. The dimensions are generous, and on an average hand the sapphire projects a strong, sophisticated profile that reads as modern and restrained rather than overtly flashy. The excellent polish contributes clean facet junctions and well defined light return, and because the stone is eye clean, its clarity supports open, minimalist settings that allow the sapphire to communicate directly with the wearer and the viewer.

Sourcing is a central consideration for collectors who prioritize ethical practice and long term stewardship, and The Natural Sapphire Company supports traceability and responsible procurement across its inventory. This yellow sapphire was acquired through channels that respect local mining regulations and partner with verified suppliers in Sri Lanka, and because it is offered untreated, the gem aligns with preferences for material authenticity and minimal intervention. For the conscious consumer, the appeal is twofold, the gem offers intrinsic geological rarity and verifiable provenance, and the purchasing path reflects attention to labor, community impact, and environmental considerations that accompany responsible sourcing. Owning an untreated Ceylon sapphire carries a cultural and historical resonance as well, because Sri Lanka has produced notable sapphires for centuries, and when that provenance is documented through a reputable laboratory report, collectors gain both certainty and context.

From a practical standpoint, this sapphire is suitable for permanent jewelry use with the appropriate setting and care, and its physical toughness as corundum supports everyday wear when secured by a well designed mount. Cleaning may be undertaken with warm water, mild soap, and a soft brush, avoiding extreme thermal or chemical exposure, and settings should be inspected periodically to ensure prongs and bezels retain structural integrity. For clients who seek further documentation, The Natural Sapphire Company provides the GIA report and additional viewable images on request, enabling an informed decision based on lab verified data and visual confirmation. This stone occupies a distinctive position in a conscientious collection, offering natural, untreated material, verified origin, and classical emerald cut refinement, attributes that appeal to collectors who value provenance, craftsmanship, and enduring aesthetic clarity.
