1.00 Ct. Greenish Blue Zircon from Ceylon (Sri Lanka)

One piece in our collection that embodies both antiquity and refined modern taste is a beautiful transparent 1.00 carat oval shape greenish blue zircon offered by The Natural Gemstone Company. This gem measures 6.77 by 4.65 by 3.31 millimeters, and it has been expertly faceted in a mixed brilliant cut to marry scintillation with a softly rounded silhouette. The material exhibits very slightly included clarity when viewed at eye level, and the intense color intensity gives a vivid blue green presence that shifts subtly with movement. The polish is excellent, which enhances the gemscintillation and allows the mixed brilliant pavilion and crown to work together in returning light to the eye. Originating from Ceylon Sri Lanka, a historic source known for producing some of the most desirable zircons in the world, this stone has been heat treated to optimize its color, a common and accepted enhancement that we fully disclose and that helps stabilize the beautiful hue that collectors and connoisseurs prize.

Zircon is one of the oldest recorded gemstones in human history, used by cultures across continents for millennia, and this lineage adds to the timeless appeal of a fine oval greenish blue example. Historically admired by royalty and traders, zircon has been praised for its fire and natural brilliance long before modern gem cutting techniques intensified its optical properties. The oval shape itself is a classic design choice that reflects centuries of jewelry tradition, offering both regal proportion and practical versatility for ring pendants and bespoke settings. The mixed brilliant cut on this gem is a contemporary adaptation of those traditions, designed to preserve weight and depth while maximizing brilliance and saturation, qualities that make this stone an heirloom style choice that can pass gracefully from generation to generation.

From an investment perspective this zircon presents a compelling opportunity for collectors who appreciate both beauty and provenance. High quality natural zircons with intense color and eye level clarity are rarer in the market than many casual buyers realize, and stones from Ceylon Sri Lanka carry additional premium value because of the islands long established reputation for gem quality. The combination of a clean, faceted oval form, excellent polish, and a stable, heat treated intense color positions this gem well for appreciation over time, particularly as demand for vivid colored gemstones continues to grow alongside constrained supply of fine natural examples. Investors should consider how this gem fits into a diversified gemstone portfolio, where tangible assets with aesthetic and historical appeal can offer resilience against currency fluctuations and market cycles. While no investment can be guaranteed, the market for collectible colored stones has shown consistent interest in pieces that offer rarity, certified provenance, and the potential for appreciation when maintained and held over a longer horizon.

Caring for and integrating this zircon into jewelry is straightforward, and proper stewardship will help protect its long term value. Zircon should be set and handled with care to avoid abrupt temperature shocks and hard knocks, and professional setting and cleaning by a trusted jeweler will help maintain its polish and brilliance. We recommend an insurance appraisal and, where desired, a gemological report to document the stones weight, measurements, clarity, cut and origin, supporting future resale or inheritance. At The Natural Gemstone Company we are pleased to assist with certification, bespoke mounting, and guidance on care and valuation so that this elegant oval greenish blue zircon can be enjoyed today and preserved as an appreciating asset for future generations. For those seeking a gemstone that bridges history and modern investment thinking, this Sri Lankan zircon is an evocative and enduring choice.
