1.20 Ct. White Zircon from Ceylon (Sri Lanka)

This beautiful transparent 1.20 carat round white zircon is presented by The Natural Gemstone Company, and it exemplifies the qualities an informed buyer will appreciate. The stone measures 6.03 x 6.07 x 3.78 mm, it is faceted in a mixed brilliant cut, and the cutting style has been optimized to capitalize on zircons inherent optical strengths. Zircon is renowned for its lively brilliance and strong fire due to its relatively high refractive index and notable dispersion, and the mixed brilliant cut on this round shape carefully balances scintillation with table light return to produce lively sparkle in a variety of lighting conditions. The near colorless body tone allows the stone to sit beautifully next to white metals, and the excellent polish enhances facet sharpness and contrast. For buyers who evaluate craftsmanship, the symmetry and finish of the facets on this gem translate directly into superior performance in wear.

On the topic of clarity and enhancement, this exemplar is graded very slightly included when evaluated at eye level, and that designation communicates that inclusions are minor and do not materially interfere with the gem’s brilliance or visual appeal. Very slightly included at eye level is a practical and honest clarity grade, it tells the purchaser that under normal viewing conditions the stone appears clean and lively, while microscopic or close inspection may reveal small natural characteristics, which in many cases confirm natural origin and add to the gem’s individuality. The color intensity is near colorless, a desirable category for buyers looking for stones that read as white and bright, and the excellent polish further elevates the perceived clarity and brightness. The stone has been heat treated, a widely accepted enhancement in the trade used to improve color by reducing brownish or yellowish undertones commonly found in natural zircon. Heat treatment in zircon, when done by experienced professionals, produces stable and attractive color results, and The Natural Gemstone Company documents this treatment to maintain transparency and trust.

Durability and daily wear considerations are important for educated buyers, and understanding where zircon sits on the Mohs scale helps set practical expectations. Zircon typically grades around 6.5 to 7.5 on the Mohs hardness scale, which places it below corundum and diamond, and above many common gemstones like fluorite and some forms of apatite. For comparison, diamond is rated 10, sapphire and ruby are rated 9, topaz is rated 8, and quartz is rated 7. These relationships mean that while zircon is suitably hard for many types of jewelry, it is more susceptible to abrasion and surface wear than sapphires or diamonds, and it can be vulnerable to sudden thermal shocks because of its crystal structure. As a buyer and wearer, consider protective settings such as bezels for rings intended for everyday use, or choose pendants and earrings for frequent wear, where the risk of contact and abrasion is lower. Cleaning is simple and effective with mild soap, warm water, and a soft brush, while aggressive ultrasonic or steam cleaning should be avoided, especially if the stone has any preexisting fractures or if extreme temperature changes might stress the heat treated material.

Sourcing and provenance are part of the value equation for discerning collectors, and this zircon traces to Ceylon Sri Lanka, a historic and reputable source known for producing clean, well colored zircons and other fine gemstones. Sri Lankan zircons often present a combination of clarity, color play, and strong optical performance that appeals to connoisseurs and designers alike, and the documented origin adds an element of provenance that enhances the stone’s narrative. At The Natural Gemstone Company we prioritize accurate description, transparent disclosure of treatments, and careful grading to empower buyers to make confident decisions. If you seek a scintillating near colorless round zircon with a refined mixed brilliant cut, reliable clarity grade, excellent polish, and Sri Lankan origin, this 1.20 carat stone is an exceptional choice, and we are available to provide additional magnified images, independent lab referral, or personalized recommendations for settings that complement both the gem and your lifestyle.
