TGL Diamond Certification


I am looking at a 30year anniversary diamond at a jeweler retailor in Fort Worth, TX. It is a combined 2 1/2 c.w. bridal set, center stone is 1 c.w Marquis.

The salesman said they have a TGL certificate, I researched and found TGL is a Thailand / Japan diamond certifier.

Is this a trust-worthy purchase for $2900.00?

Thanks for a quick response.



Hi Donnie,

Non-guaranteed reports doesn’t give the buyer any sort of security. Look for a fully bonded appraisal (F.B.A.). What are the specifications of the diamond?
