Buyer questions
Who do you work with?
We focus on independent jewelers, custom bridal studios, growing jewelry brands, online jewelry retailers and professional wholesale buyers. The site is not designed as a direct-to-consumer store.
Which specifications can you source?
The current starting scope includes round, oval, emerald and radiant shapes. Carat, color, clarity, growth method and certification availability are checked against each request.
Can you source IGI or GIA reports?
Certification preferences can be included in a request. Availability and the report format are confirmed for the specific stone. A grading report does not guarantee price, investment value or resale value.
Do you supply CVD and HPHT stones?
Requests may specify CVD, HPHT or no preference. The growth method and any disclosed post-growth treatment must be reviewed for the specific item.
What is the minimum order quantity?
Confirmed with every quotation based on specifications and quantity.
How are shipping, duty and tax handled?
Shipping options are confirmed for the destination and order. Duty, VAT and import charges depend on destination, product classification, origin and declaration conditions. We do not promise tax-free delivery.
