3.50 CT Oval Faceted Tanzanite Vintage Necklace in 14kt Yellow Gold

David Stern Jewelers presents a captivating 3.50 CT Oval Faceted Tanzanite Vintage Necklace set in warm 14kt yellow gold, an extraordinary piece that showcases one of the gemstone world’s most recent and remarkable discoveries in a design inspired by jewelry’s golden age. This exceptional vintage 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 creating a sense of urgency among collectors who recognize this gemstone may become unavailable in their lifetime.

The magnificent 3.50 carat oval faceted tanzanite represents a substantial and impressive centerpiece that commands attention with its otherworldly color. Tanzanite’s unique blue-violet hue, caused by trace amounts of vanadium within the mineral zoisite, cannot be found in any other gemstone, giving tanzanite jewelry an instantly recognizable and distinctive appearance. The oval faceted cut maximizes the tanzanite’s natural brilliance and pleochroism—the optical phenomenon where the stone displays different colors when viewed from different angles, shifting between blue, violet, and burgundy depending on the light and viewing direction. The International Gem Society explains that tanzanite’s trichroic nature creates a dynamic visual experience that changes throughout the day as lighting conditions shift, ensuring this necklace will never appear static or predictable.

This exceptional tanzanite is beautifully complemented by 1.00 carat of round European cut diamonds exhibiting J/K color and SI-2/I1 clarity, an important vintage detail that confirms the authentic period character of this piece. European cut diamonds, also known as old European cuts, were the predominant diamond cutting style from approximately 1890 through the 1930s, featuring a high crown, small table, and open culet that creates a distinctive romantic sparkle quite different from modern brilliant cuts. These antique-cut diamonds add significant historical value and character to the necklace, as they represent the craftsmanship and aesthetic preferences of a bygone era when diamonds were cut by hand to maximize beauty rather than weight retention.

The J/K color range places these diamonds in the lower end of the near colorless to faint color categories on the GIA diamond color grading scale. When set in warm yellow gold, these lower color grades actually become an aesthetic advantage, as the diamonds pick up the golden tone and appear warmer and more harmonious with the vintage aesthetic. The SI-2/I1 clarity grades indicate these diamonds have noticeable inclusions that may be visible to the naked eye, which is characteristic and expected in antique jewelry. These inclusions tell the story of the piece’s age and authenticity while contributing to its unique character.

This Necklace has a Total Carat Weight of 4.50 ct tw with Blue color and Excellent clarity. The “Excellent” clarity designation for the tanzanite indicates outstanding transparency and crystal structure, with the stone displaying remarkable purity that allows light to penetrate deeply, creating maximum color saturation and brilliance. Tanzanite ranks 6.5 to 7 on the Mohs hardness scale, making it suitable for necklaces and pendants that don’t receive the constant abrasion that rings endure, though it should be worn with reasonable care to preserve its beauty.

This Necklace has a gold weight of approximately 3.8 grams, crafted in elegant 14kt yellow gold that provides the perfect warm backdrop for both the blue-violet tanzanite and the vintage European cut diamonds. According to the World Gold Council, yellow gold has been the traditional choice for fine jewelry throughout history, with its warm, rich tone creating a sense of heritage and timeless elegance. The combination of yellow gold with tanzanite creates beautiful color contrast while the vintage-style setting evokes the romance and craftsmanship of early 20th-century jewelry design.

This Necklace comes with a 16 inch chain with a spring ring clasp in 14kt yellow gold. The spring ring clasp is another period-appropriate detail that enhances the vintage character of this piece, as this type of closure was commonly used in antique jewelry. The 16-inch length positions the tanzanite pendant at the collarbone for maximum visibility and creates the elegant, close-fitting drape characteristic of vintage necklace designs. This length is particularly flattering and works beautifully with period-inspired fashion as well as contemporary attire.

What distinguishes this tanzanite necklace is its authentic vintage character combined with the relative modernity of tanzanite as a gemstone species. Tanzanite wasn’t discovered until 1967, meaning this piece represents either a vintage-style creation or a carefully preserved example from tanzanite’s early years in the jewelry market. The American Gem Society notes that tanzanite has become increasingly valuable as mining operations approach depletion, with experts predicting the supply may be exhausted within the next few decades. This scarcity, combined with growing global demand, has made fine tanzanite an increasingly sound acquisition for collectors and investors.

The European cut diamonds add another layer of collectibility and value. According to antique jewelry specialists, European cut diamonds command premium prices among collectors who appreciate their romantic, candle-lit sparkle and historical significance. The combination of these vintage-cut diamonds with substantial tanzanite creates a piece that bridges multiple eras of jewelry history while maintaining complete wearability for contemporary life.

This piece of Fine Custom Jewelry 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 including the vintage European cut diamonds, and replacement value for insurance purposes. The GIA Graduate Gemologist credential represents the jewelry industry’s most respected gemological qualification, ensuring you receive authoritative expertise regarding this distinctive and valuable acquisition.

This exceptional tanzanite and diamond necklace embodies vintage elegance with the allure of one of the world’s rarest gemstones. The blue-violet color of the tanzanite creates a sophisticated alternative to traditional sapphires, while the European cut diamonds provide authentic period character that collectors and connoisseurs particularly appreciate. Whether you’re seeking a distinctive piece with genuine vintage appeal, a December birthstone gift with exceptional presence (tanzanite is one of December’s birthstones), or an investment-quality addition to your jewelry collection that combines rarity with beauty, this vintage necklace offers the quality, character, and lasting value that discerning jewelry enthusiasts demand.
