6.38 CT Oval Tanzantie Faceted Couture Ring in 18kt White, Rose and Yellow Gold

David Stern Jewelers presents a spectacular 6.38 CT Oval Faceted Tanzanite Couture Ring set in an artistic combination of 18kt white, rose, and yellow gold, an extraordinary piece that showcases one of the gemstone world’s most captivating discoveries in a sophisticated tri-color design. This magnificent creation features a stunning oval faceted tanzanite displaying a mesmerizing blue color with characteristic violet undertones, the signature hue that has made tanzanite one of the most sought-after colored gemstones since its discovery in 1967. According to the Gemological Institute of America, tanzanite is found in only one location on Earth—the Merelani Hills of Tanzania near Mount Kilimanjaro—making it geographically rarer than diamonds and approximately one thousand times rarer than sapphires, creating urgency among collectors who recognize this gemstone may become unavailable within their lifetime.

The magnificent 6.38 carat oval faceted tanzanite represents a substantial and impressive centerpiece that commands immediate attention with its otherworldly color and exceptional size. Tanzanites over 5 carats are exponentially scarcer than smaller stones, with the per-carat value increasing dramatically as size increases. The oval faceted cut maximizes the tanzanite’s natural brilliance and showcases its remarkable trichroism—the optical phenomenon where the stone displays different colors when viewed from different angles, shifting between blue, violet, and burgundy depending on the light source and viewing direction. The International Gem Society explains that this color-shifting property creates a dynamic visual experience that changes throughout the day, ensuring this ring will never appear static or predictable.

This exceptional tanzanite is beautifully complemented by approximately 1.51 carats of accent diamonds that enhance the centerpiece gemstone’s brilliance while adding substantial sparkle and value to the overall composition. The diamonds create an elegant setting that frames the tanzanite’s commanding presence while maintaining focus on the spectacular colored gemstone. The careful integration of diamonds with the tri-color gold design demonstrates the sophisticated artistry that defines couture jewelry.

This Ring has a Total Carat Weight of 7.89 ct tw with Blue color and Fine clarity. The “Fine” clarity designation indicates exceptional transparency and crystal structure, with the tanzanite displaying outstanding purity that allows light to penetrate deeply into the gemstone, creating maximum color saturation and that coveted velvety depth that connoisseurs seek. Fine clarity tanzanites of this substantial size are increasingly rare, as most tanzanite contains visible inclusions. This clarity grade represents the upper echelon of tanzanite quality and commands premium values in the marketplace.

What truly distinguishes this ring is the extraordinary artistic use of tri-color 18kt gold—white, rose, and yellow gold harmoniously integrated into a unified design. This sophisticated metalwork approach, also known as tri-gold or three-tone gold, requires exceptional craftsmanship to seamlessly blend different gold alloys into a cohesive aesthetic. According to the World Gold Council, 18kt gold contains 75% pure gold, offering substantially higher precious metal content than 14kt gold. The three different gold colors are achieved through different alloying metals: white gold uses palladium or nickel, rose gold incorporates copper, and yellow gold maintains the natural golden appearance with silver and copper alloys.

The tri-color gold design creates visual depth and dimension that cannot be achieved with a single metal tone. The interplay of warm rose and yellow tones with cool white gold creates a contemporary yet timeless aesthetic that complements the tanzanite’s blue-violet hues from multiple angles. This level of metalwork artistry elevates the ring from simple jewelry to wearable sculpture, demonstrating the master goldsmith techniques that define couture jewelry.

This Ring is Size 6.5 which can be sized by David Stern Jewelers to ensure a perfect fit while maintaining the structural integrity and aesthetic balance of the tri-color design. Weighing an impressive 21 grams, this ring represents extraordinary precious metal content that adds significant intrinsic value beyond the gemstones themselves. The 21 gram weight in 18kt gold indicates substantial, museum-quality construction with proper reinforcement and metalwork that will endure for generations. This weight is approximately three to four times heavier than typical cocktail rings, reflecting the investment-grade quality of materials and construction.

The American Gem Society notes that tanzanite has become increasingly valuable as mining operations approach depletion, with gemological experts and industry analysts predicting the supply may be exhausted within the next 20-30 years. This impending scarcity, combined with growing global demand particularly from Asian markets, has made fine tanzanite an increasingly sound acquisition for collectors and investors. Large tanzanites with fine clarity represent particularly strong investment potential, as they will become exponentially scarcer as the deposit is depleted.

Tanzanite ranks 6.5 to 7 on the Mohs hardness scale, making it suitable for rings that receive reasonable care. While not as hard as sapphires or rubies, tanzanite is perfectly durable for engagement rings and statement jewelry when worn with appropriate care to avoid harsh impacts. The trade-off for slightly lower hardness is tanzanite’s utterly unique and captivating color that cannot be found in any other gemstone species, making it worth the minor additional care consideration.

This Ring also includes a full complementary Jewelry Appraisal written by David Stern, G.I.A Gemologist. This professional appraisal provides detailed documentation of specifications, gemstone characteristics, the unique tri-color gold construction, and replacement value for insurance purposes—particularly important for a piece of this significance and value. The GIA Graduate Gemologist credential represents the jewelry industry’s most respected gemological qualification, ensuring you receive authoritative expertise regarding this museum-quality acquisition.

This exceptional tanzanite ring embodies contemporary luxury with artistic sophistication. The combination of a substantial 6.38 carat tanzanite with fine clarity, nearly 8 carats total gemstone weight, and the extraordinary tri-color 18kt gold design creates a piece that stands apart from conventional jewelry. Whether you’re seeking a distinctive engagement ring that defies tradition, a significant milestone gift celebrating a December birthday (tanzanite is December’s birthstone), or a crown jewel for your collection that combines rarity with artistic merit, this couture creation offers the quality, uniqueness, and investment value that the world’s most discerning collectors demand.

The substantial size ensures this ring makes a confident statement, while the sophisticated tri-color gold design demonstrates refined taste and appreciation for master craftsmanship. This is jewelry for those who appreciate pieces with soul and artistry, who understand that true luxury lies not just in carat weight but in the harmonious integration of exceptional materials with masterful design and execution.
