Do your items come with gemological certification?

Select items include gemological certification. For diamonds, we use GIA (Gemological Institute of America) reports. For colored gemstones — including sapphires, rubies, and emeralds — we rely on SSEF (Swiss Gemmological Institute), Gübelin Gem Lab, or AGL (American Gemological Laboratories). These three laboratories set the global standard for colored stone origin and treatment disclosure. Certification details are noted in the product description and included with your purchase.

Yes, we offer financing options through Affirm, allowing you to pay over time. For more details, visit our Financing page.

What is your return policy?

We accept returns within a specified period as long as the item has not been customized, altered, or resized. Please review our Return Policy for full details.

What makes a Kashmir sapphire special?

Kashmir sapphires come from the Padar Valley in the Himalayas, a deposit that has been essentially exhausted since the early 20th century. Their defining characteristic is a velvety cornflower blue caused by microscopic silk inclusions that scatter light, producing a soft glow unlike any other sapphire origin. Unheated Kashmir sapphires with origin reports from SSEF or Gübelin are among the rarest and most valuable colored gemstones in the world.

What does 'unheated' mean for sapphires and rubies?

Heat treatment is applied to the vast majority of sapphires and rubies on the market to improve color and clarity. An unheated stone retains its natural color as formed in the earth, which collectors and connoisseurs prize as authentic and rare. Unheated status is confirmed by laboratory report from SSEF, Gübelin, or AGL. Unheated Kashmir sapphires and unheated Burmese pigeon's blood rubies command significant premiums over heated equivalents.
