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.

Laboratory certification provides an impartial judgement of the characteristics and quality of each diamond. This certification (called a grading report, or dossier by GIA) gives the purchaser added confidence that the diamond received is as described by the seller. The diamond certificate is also valuable for insurance purposes, as it provides a professional, independent evaluation of the diamond.

A laboratory certification is not an appraisal. An appraisal seeks to establish the value of an item, mainly for insurance purposes. A diamond certificate does not evaluate a diamond's market value, only its characteristics and quality. That said, diamond certification from a reputable laboratory is invaluable in generating an accurate appraisal.

GIA CERTIFICATIONWe here at Gemsatelier only sell diamonds that have been certified by the Gemological Institute of America (GIA). GIA is the world's oldest, largest, and one of the most respected independent laboratories. Unlike some other labs, GIA is not owned or partially owned by diamond wholesalers or retailers, and is a non-profit organization. GIA actually developed the "4 C's" diamond grading system (used almost universally today) to provide truly objective standards in the evaluation of a diamond.

Every Gemsatelier Diamond is accompanied by its GIA Grading Report or Dossier. These diamond grading certificates may be viewed prior to purchase by clicking the name "GIA" next to any diamond.

Buying Tip:Only buy diamonds which have been certified by a reputable lab. Do not accept certifications created by retailers, even if they claim to be GIA trained.Keep your diamond certificate in a safe place. It provides invaluable security in the case of loss (helping to establish the quality and size of diamond required for equitable replacement), trade, or resale. Whenever the diamond must leave your possession (for example, to be cleaned), always let the party taking possession know you have a certificate. Knowing you can positively identify your diamond removes any temptation on the part of the third party to commit fraud (such as switching the diamond for one of lower quality).A copy of your uniquely numbered GIA certificate is kept permanently on file with the GIA, and can be replaced at anytime if lost or destroyed.
