13.15 Ct. Greenish Brown Zircon from Ceylon (Sri Lanka)

This striking transparent 13.15 carat oval greenish brown zircon measures 14.96 x 11.40 x 7.81 mm, and is faceted with a mixed brilliant cut that maximizes its fire and scintillation. Graded eye clean at normal viewing distance, and displaying intense color intensity with an excellent polish, this stone delivers a rare combination of clarity and lively optical performance. Originating from Ceylon Sri Lanka and heat treated to enhance and stabilize its rich tones, this zircon is a naturally occurring treasure that stands out from common marketplace options. Its balance of weight and proportions makes it ideal for prominent jewelry designs where both presence and refined sparkle are desired.

In terms of durability this zircon offers real advantages for daily wear when set thoughtfully. With a robust hardness in the high six to mid seven range, excellent polish, and the benefit of heat treatment to relieve internal strain, it resists everyday abrasion better than many softer gems such as quartzes or many varieties of tourmaline. Compared to topaz this zircon often shows stronger dispersion and sparkle, and compared to synthetic alternatives it brings genuine natural rarity and provenance from Sri Lanka, making it a superior value for collectors and those who want authentic gemstones. While zircon does have distinct cleavage planes like other minerals, choosing protective settings such as a bezel or a halo ring design will safeguard its edges and make it perfectly suited for daily wear, including rings and pendants that see regular use. The Natural Gemstone Company recommends routine gentle cleaning and periodic inspection of the mounting to maintain brilliance and stability. For customers seeking a gemstone that combines eye clean clarity, impressive carat weight, intense color, and a lively mixed brilliant cut, this 13.15 carat Ceylon zircon represents an exceptional choice. It is more affordable than sapphire or diamond of similar visual impact, yet more distinctive and naturally sourced than synthetic imitations, making it a compelling and practical choice for everyday luxury.
