Diamond Certification

Diamond certification is a critical component to consider while purchasing an engagement ring. Without a certificate, subjective characteristics such as color, cut, clarity, and even carat cannot be verified. Think of a certificate as authentication of a diamond and its features. There are many providers of independent diamond certificates, but few are considered reliable.

All Four Mine diamonds are GIA certified. The Gemological Institute of America, or GIA, is a non-profit, industry pioneer in identification and verification of diamond characteristics. Its high standards of grading and strict adherence to respected practices make it the most reliable choice for certified diamonds. GIA diamonds may carry a slight premium, but it is well worth the price for the reliability and confirmation that your diamond grading is precise and correctly valued.
