Frequently Asked Questions
Are your certificates recognized internationally?
Yes. All certifications are conducted by GIA-certified gemologists and meet global standards accepted by buyers, jewelers, and institutions worldwide.

Can I send gemstones to you from abroad?
Absolutely. We work with secure international couriers to receive and return gemstones safely, accompanied by detailed tracking and insurance options.

Evaluation focuses on assessing a gem’s market value, while certification verifies its authenticity, treatment status, and origin. Both are often performed together for a comprehensive understanding.
