Radial Earrings | Keum-boo + yellow sapphire

$400.00

Brilliant-cut yellow sapphires and carefully textured silver surfaces float freely and catch the light. 24K gold surfaces were created using keum-boo, an ancient Korean technique that fuses gold into the surface of silver, complementing darkened patina and Australian sapphires.

Inspired by the microscopic worlds beneath the sea and the surface of our cells, these radially patterned earrings celebrate the hidden beauty of nature.

Sterling silver, 24K gold keum-boo, and canary yellow sapphires.

20 x 20 x 4 mm on silver threader chain (45mm drop).

  • 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.
