FAQ

Yes. 100% yes. We are perfectionists when it comes to the quality of our jewelry, and that starts with our sourcing. We work with suppliers who abide by the Kimberley Process, so we only work with conflict-free materials. Rest assured—we would never work with or sell a conflict diamond or gemstone. We’re fully committed to caring for the environment, maintaining high ethical standards, practicing sustainable sourcing methods, and using recycled gold.

Our jeweler works at our studio here in Mammoth Lakes, California, but we don’t have a traditional, brick-and-mortar storefront. So, we don’t have regular store hours, and our studio is available by appointment.

Yes, we specialize in handcrafting a wide variety of unique and made-to-order pieces that tell stories with gemstones and gold. "I have an heirloom stone. Can I use it in my setting?" Yes, certainly. We will reset diamonds and gemstones that are GIA or AGL certified. If your heirloom stone is not certified then we will be send it to GIA or AGL for certification*. *Clients are responsible for certification costs.

We are so sorry that happened! When those pieces sell, they’re (almost always) out of stock, but there’s a chance that we happen to have the stone you need. It really depends on the availability of the stones. We love dreaming up new designs, and our collections are ever-changing. So be sure to check our New Arrivals to find the pieces that are fresh from the jewelers’ bench.

Don’t worry—You can purchase your ring now and select "Mail me a sizer" in the size drop-down menu. That tells our team to hold off on the sizing until you’ve had a chance to try out the sizer.

We don’t recommend it. Sizing varies from jeweler to jeweler. Instead, use one of our sizers to avoid having to send your ring back for resizing.
