How to Build Your Own Ring

1. Choose a center stone.

Most of our loose gemstones, including sapphires, diamonds, amethysts, garnets and more, can be set in one of our signature settings. Explore out center stones to choose a stone to add to your favorite setting.

2. Select your setting.

Choose one of our hand-picked signature settings in 14K white gold, 14k yellow gold, 14k rose gold, or platinum. Each setting compliments a variety of stone shapes & styles and many have a wedding band to complete your set.

3. Add to cart to create.

Add your loose gemstone + chosen signature setting to your cart to build your own ring. Your ring will take 6-8 weeks to complete and will come with a sustainably-sourced walnut wood ring box to hold your piece.

Custom orders take 5-7 weeks once we have all of the components in place (stones chosen, mounting chosen, ring size, etc). 

All orders over $500 are shipped fully insured with 21+ signature confirmation through either FedEx or UPS. Orders under $500 will ship USPS. We'll send you an email confirming the shipping address prior to shipping and you MUST respond to this email or your package will NOT ship. 

International clients, we ship with DHL and are happy to ship to your country if possible. You are responsible for all duties, fees and taxes for your shipment.
