10K Yellow Gold Marquise Tanzanite Three-Stone Bypass Ring

We price each piece based on its total weight and gold purity, using a simple and consistent formula tied to real market values.

For example, if a piece weighs 3 grams and is 14K gold, we use all 3 grams, apply the 14K gold value, and multiply by 2 to determine the final price.

Unlike traditional retailers, we don’t add inflated markups for stones or brand names, helping keep prices fair, transparent, and more competitive.

Every item in our inventory undergoes a rigorous multi-point inspection. We use professional XRF (X-Ray Fluorescence) technology to verify the exact metal composition and karat weight. We guarantee that every piece is 100% authentic precious metal as described.

Yes. All jewelry is professionally cleaned and sanitized before being listed. We use industry-standard techniques such as ultrasonic cleaning to safely remove residue and buildup from the metal.

Ultrasonic cleaning is a widely used, non-invasive method for cleaning metal jewelry. However, certain delicate stones or settings may require alternative cleaning methods. When needed, we adjust our process to ensure each piece is handled safely and appropriately.

Each piece is handled individually to ensure it’s cleaned thoroughly while maintaining its integrity. Our goal is to deliver jewelry that is clean, presentable, and ready to wear.

We source our inventory directly from individuals like yourself across the country through our circular marketplace. This allows us to offer unique, one-of-a-kind estate and vintage pieces while promoting a more sustainable, eco-friendly way to shop for luxury.

We want you to be completely confident in your purchase. If a piece isn't exactly what you expected, we offer a 7-day return window. Please ensure the item is in its original condition to qualify for a full refund.

Most orders are processed and shipped within 2–3 business days and take 5-7 business days to arrive. We use secure, insured shipping methods to ensure your jewelry arrives safely. Once your order is on its way, you’ll receive a tracking number via email to monitor its progress.

Since our pieces are one-of-a-kind, we provide exact measurements (length for chains, mm width, and ring sizes) in every product description. We recommend measuring a piece you already own or using a standard sizing guide before purchasing.
