Much of our work is made to order, so please allow time for your piece to be created before shipping. Please let us know if there is a specific date you would like your jewelry by and we will do our best to help.

Shipping within the USA is free. We offer complimentary 2-day delivery for all orders over $250, and complimentary Priority Overnight for orders over $2000.

We ship internationally with a $60 flat-rate fee. International orders over $500 are sent by FedEx Priority International. Please be aware of your local customs fees and import duties, we do not cover these.

For further information, please see our shipping and returns policy.

Please select your ring size at checkout. If you don’t see your ring size, please let us know, it’s still likely we can create something that will fit.

We encourage you to have your ring size measured professionally, or with reliable ring gauges. The fit of a ring is especially important and a measurement being off by a small amount can have a big impact on fit. Measurements made using paper and alternative approaches to measure circumference are known to be unreliable and best avoided.

We pride ourselves on handcrafting limited quantities of fine jewelry using ethically sourced precious materials. We don’t outsource our manufacturing or mass-produce our items. Instead, each piece is individually created in our NYC studio. We want each piece to be created specially, with you in mind, so please don’t hesitate to reach out - we’re more than happy to discuss a bespoke design, gemstones, and anything you’d like to make your piece even more personal.

We endeavor to provide the best possible images of our work to help your decision. Many of the gemstones we work with, especially Australian sapphires, have unique colors. This means their color may vary from those shown in the photos and is part of what makes jewelry with natural gemstones unique and beautiful. If you’re looking for a particular color, please let us know, we are happy to provide photos of gemstones before setting.

It is common practice for the majority of sapphires to be heat treated to improve color and clarity. This is a permanent, irreversible treatment with no radiation, chemicals, or health risks. We use both untreated and heated natural sapphires, and will specifically note if we can confirm a sapphire is unheated. We do not use sapphires that have been subject to other treatments, such as chemical diffusion and beryllium treatment. Our work only makes use of ethically sourced gemstones and high-quality diamonds. We only source conflict-free diamonds that comply with the UN Kimberley Process. Wherever possible, we utilize raw materials and alloys that have been recycled and have been processed in a responsible and sustainable manner.
