Want to see this stone in person?
We invite you to visit our Brookline shop to sit down with our bench jeweler and begin your project. To view this stone in person, we require our standard $350 design and sourcing deposit to order it in for you. Once ordered during your shop visit, we bring your stone directly to our bench within 2 to 3 business days for a 7-day private viewing window. This deposit covers fully insured transit, custom 3D CAD design renderings for your mounting (with up to 2 revisions), and a physical 3D resin model to try on, with 100% applied toward your finished ring total.
What if the stone isn't the right fit?
If you view the stone in person and prefer a different color, shape, or size, your $350 deposit transfers completely toward sourcing an alternate vault gem or crafting your custom setting.
Note: Vault gemstones are reserved for full custom jewelry builds. Completed custom ring projects featuring these natural gems start at $5,000. Custom mountings are quoted separately during your consultation based on your chosen precious metal and design details.
