American Diamond Laboratory® (ADL)

Established in 1986, the American Diamond Laboratory® is a division of Ascot Diamonds and is staffed by both GIA Diamond Graduates and Graduate Gemologists. 

In an effort to provide the maximum protection for our clients, the ADL applies the highest international standards to every service.    

Services:

Diamond and Jewelry Appraisals:  ADL appraisals are designed to protect clients for a loss incurred within 5 years of the appraisal date.  This value is an educated ‘replacement value' estimate based on history, current market conditions and trends.  We recommend that all fine jewelry appraisals are updated every 5 years. 

Diamond Grading and Certification:  ADL Diamond Grading reports strictly conform to GIA (Gemological Institute of America) cut, color and clarity standards and ADL certificates come with a 'GIA equivalent' guarantee. 

Diamond Re-Cutting:  The ADL has in-house, three dimensional computer imaging technology to predict the final weight of a diamond being considered for re-cut.  In addition we have the skills and personnel to advise whether the recut is worthwhile.

Laser Inscription:  The ADL has an Excimer Laser diamond engraving machine, capable of inscribing a number or message on a diamond without causing any damage to the stone or affecting value in any way.  Laser inscriptions are visible only under 10x magnification, do not affect value and can be removed by skilled diamond cutters without impacting the stone in any way.
