1.99 Ct. Yellow Zircon from Ceylon (Sri Lanka)

One beautiful transparent 1.99 carat oval shape yellow zircon from Ceylon, Sri Lanka, offered by The Natural Gemstone Company, presents an immediate visual appeal and technical merit that will satisfy an informed buyer. The stone measures 8.19 by 6.18 by 4.26 millimeters, and its mixed brilliant cut has been executed to balance face up brilliance with internal fire. The cut proportions and excellent polish give lively light return across the oval table, while the intense color intensity produces a vivid golden yellow that reads as both warm and highly saturated in hand. Clarity is graded as very slightly included when evaluated at eye level, which means the inclusions are minor and do not interfere with the stone s transparency or its capacity to transmit light, and the overall appearance is clean and gemologically attractive. This item has been heat treated, a standard and stable enhancement for zircon color, and treatment is fully disclosed.

From a gemological perspective this zircon is an excellent example of the species zircon, composed of zirconium silicate, with optical properties that set it apart from many other yellow gemstones. Zircon typically displays high refractive indices and notable dispersion, properties that create the crisp brilliance and lively fire you can observe in strong light. The stone s specific gravity is high compared with many common gems, which helps explain a substantial 1.99 carat weight for an oval of these dimensions. The very slightly included clarity grade means that at loupe or eye level the stone presents with minimal internal features, which preserves clean light performance and supports a higher market value compared with more included examples. Origin matters to collectors and connoisseurs, and Ceylon, Sri Lanka, is known for producing high quality zircons with attractive color and clarity, which adds provenance value to this piece.

When considering everyday wear durability it is important to compare zircon on the Mohs hardness scale, so you can make an informed setting and care decision. Zircon typically ranges from approximately 6.5 to 7.5 on the Mohs scale, with gem quality material commonly around 7.5, which positions it above common jewelry minerals such as quartz, which is 7, and below corundum varieties such as sapphire and ruby, which register at 9, and far below diamond at 10. This means the stone is moderately hard and will resist many scratches that affect softer gems, but it is not as scratch resistant as corundum or diamond, and it can be susceptible to abrasion or chipping if subjected to heavy knocks or abrasive contact. For these reasons we recommend protective settings for rings intended for daily wear, such as bezel or partial bezel profiles, or placing the stone in pendants and earrings for a lower risk of impact. Avoiding abrasive contacts, and protecting the stone from sudden temperature extremes, will preserve its polish and color. Routine cleaning with warm soapy water and a soft brush is safe, and prolonged exposure to steam cleaning or aggressive chemicals is not recommended.

For the educated buyer this yellow zircon represents a compelling balance of color intensity, clean eye level appearance, and classical provenance, and it offers optical characteristics that are distinct from other yellow gems due to its high dispersion and adamantine luster. The mixed brilliant cut and excellent polish maximize visual performance for use in custom jewelry, and the 1.99 carat weight makes this stone an excellent focal point for a ring, pendant, or bespoke commission. Heat treatment has been applied to enhance and stabilize the color, and The Natural Gemstone Company discloses this enhancement openly, and can assist with independent certification on request to document origin and treatment. If you prefer a setting recommendation for long term wear, or if you would like photographic detail or a gemological report, we can provide further technical information and assistance to ensure this Ceylon yellow zircon meets your expectations and performs beautifully for years to come.
