Colored Stone Certification and Appraisal

Dufau Gemological Laboratories analyzes and grades individual colored stones and then issues an independent certification.  DGL grades colored stones to GIA standards and tests every material submitted to determine whether it is natural or not, and discloses any known treatments discovered during analysis. 

Star Ruby. A phenomenon known as asterism.

DGL ensures the integrity and accuracy of every report it issues by employing expert gemologists and appraisers. DGL ensures the objectivity of every report it issues by not allowing the gemologists to know from whom the colored stones were submitted.

DGL  is the only laboratory in Indonesia that provides customers with current international values of their colored stones. This  Appraisal Report is not an opinion of value on our part but a consensus of vast samplings of market values and current retail prices. The appraisal document describes all qualitative and quantitative attributes necessary to arrive at the value conclusion.  DGL reports an international retail market price.

Testimonials

What are people saying about DGLColored Stone Reports?

Dear Dennis,

The appraisal with the certification has become a routine sales tool. Not only are our customers assured of the authentication of the gemstones but also the retail price. Yours is the most consistently accurate appraisal. The only problem is I have to tell the customers that yours is the true price and a lot of the other Labs have inflated appraisals. I show them the inside of your appraisal cover for your explanation. That's helpful.

Dear DGL

I am old fashioned. I like your name on the business card. All these American, National,Global,European Gem labs. I like it when there is an actual person's name on the company sign. I know who to go to if there is a problem and I know if your names on it you are inclined to keep a high standard. Thanks again for the certs.

Thanks,

Walter Hills
