American Diamond Laboratory ® (ADL)
Established in 1986, the American Diamond Laboratory® is a division of Ascot Diamonds staffed by both GIA Diamond Graduates and Graduate Gemologists.
In an effort to provide the appropriate protection for our clients, the ADL applies the highest standards to every service we provide.
Diamond and Jewelry Appraisals: ADL appraisals are designed to protect clients for a loss incurred within 2 years of the appraisal date. This value is an educated ‘replacement value’ estimate based on history, current market conditions and trends. We recommend that your fine jewelry appraisals be updated every 2 years.
Diamond Grading and Certification: ADL Diamond Grading reports conform to GIA (Gemological Institute of America) cut, color and clarity standards.
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 and the personnel to advise whether a recut is advisable.
Laser Inscription: The ADL has an Excimer Laser diamond engraving machine, capable of inscribing a number or message on a diamond without causing damage to the stone or affecting value.
Laser inscriptions are visible only under magnification, and can be removed by skilled diamond cutters without impacting weight or quality grades.
