Frequently Asked Questions
What makes a piece “One-of-a-Kind”?
Each One-of-a-Kind piece is built around rare, hand-selected gemstones — sometimes more than one — each with its own unique color and character, so no two pieces are ever exactly alike.
Are these gemstones certified?
Certification varies by piece. Many of our One-of-a-Kind pieces carry independent AIGS or GUILD gemological certification; others come with Kai’s own in-house certificate. Either way, documentation of your gemstone comes with your piece.
What can I expect when I order a One-of-a-Kind piece?
Every One-of-a-Kind piece is ready to ship and arrives beautifully gift-packaged, with free express shipping, a 30-day return window, and complimentary resizing if needed — perfect for a milestone purchase or a gift.
Can I customize a One-of-a-Kind piece?
Because each stone is unique, customization options vary by piece. Contact us and we’re happy to talk through what’s possible for the piece you’re considering.
A piece I loved has already sold — can I get something similar?
Because each gemstone is one of a kind, we usually can’t recreate the exact stone once a piece sells — but we’re often able to recreate the design and customize a similar style around a new gemstone. Contact us and we’ll help you explore what’s possible.
How often do new pieces arrive?
Our One-of-a-Kind pieces tend to sell quickly, and new ones arrive weekly — so a piece you love may not be here for long.
