Certified with Trust

At Cui & Co., we believe every piece of jade should carry not just beauty — but authenticity you can trust.

Our Commitment

Each piece in our Jade Collection is carefully hand-selected and verified to be 100% natural Type A jadeite — untreated, undyed, and unaltered. Every jade item comes with a professional authentication certificate issued by an accredited gemological institution.

For Other Gemstones

Pieces crafted with natural stones such as chalcedony, mother of pearl, or zircon are clearly stated in each product description. While these materials may not come with certificates, they are all sourced from trusted suppliers and undergo strict internal quality checks before reaching you.

Why It Matters

We believe transparency builds trust. That’s why every Cui & Co. piece — whether jade or gemstone — carries our promise of authenticity, craftsmanship, and integrity.

“Every stone tells a story — ours begins with honesty.”
