The round cut is the most iconic and beloved gemstone shape in engagement rings—known for its perfect symmetry, sparkle, and timeless appeal. When set with tanzanite, a rare gemstone found only in Tanzania, the result is both traditional and unique.
Our Round Tanzanite Engagement Ring collection includes:
– Solitaire rings with sleek or vintage-inspired bands
– Diamond halo and double halo designs for extra brilliance
– Three-stone and side-stone rings with added symbolism
– Minimalist and ornate styles to match every personality
Tanzanite, the birthstone for December, is prized for its trichroic color (blue, violet, and burgundy tones) and its spiritual symbolism—transformation, peace, and intuition. In American fine jewelry, round tanzanite rings are gaining popularity as non-traditional engagement rings for those who value color, rarity, and personal expression.
Whether you're planning a winter proposal or simply want a timeless shape with a colorful twist, round tanzanite engagement rings are a stunning choice.
Each ring is made using 100% solid 14K or 18K gold, not gold-plated or filled. We use natural, untreated tanzanite gemstones, ethically sourced and hand-selected for their brilliance, clarity, and color.
All pieces are nickel-free and hypoallergenic, ensuring long-lasting comfort and wearability for all skin types. Crafted for durability and elegance.
We believe in complete transparency with our customers. Each Round Tanzanite Engagement Ring comes with certification for the tanzanite stone used in the design.
Tanzanite: Certified by reputable gemological labs to confirm authenticity, origin, and natural quality.
Additionally, all rings are stamped with the gold purity mark (14K or 18K) and include a complete invoice, ensuring your purchase is fully documented and authentic.
Each ring is handcrafted by our expert artisans who specialize in fine gemstone engagement rings. From shaping the setting to polishing every edge, every step is done with care and precision.
Before shipping, each ring undergoes a multi-point quality inspection to ensure a secure setting, flawless finish, and heirloom-level craftsmanship. This is fine jewelry made for life’s most important moments.
