What is JSA's Stolen Jewelry Website? 
The Stolen Jewelry Website of the Jewelers' Security Alliance provides a central clearinghouse for the jewelry industry, law enforcement, insurance personnel and the general public to share information on jewelry that has been stolen or recovered in the United States . The listings include watches, gems and jewelry. Searches and listing are free. This database is a diamond, jewelry and watch industry supported database that went live in January 2006 and will become increasingly valuable as the number of users increases and the number of items posted grows. This service was developed through a generous grant to the Jewelers' Security Alliance from the JCK Jewelry Industry Fund. 

What can JSA do for law enforcement personnel?   

In addition to its Stolen Jewelry Database, JSA has the largest and most comprehensive database of crimes against the jewelry industry in the U.S. This database includes thousands of cases with information on suspects, M.O.s, vehicles and unusual crime characteristics that JSA will share with law enforcement personnel. From this database JSA is able to produce customized reports to answer specific investigative questions.

Diamond laboratories and grading reports:

Today almost all large diamonds have grading reports that are produced by gem laboratories and describe the diamond by weight, shape, measurements, cutting style, proportions, color and clarity. Contact JSA on how this can be of help to law enforcement. 

Laser inscriptions
Many diamonds now have laser inscriptions on the stone. These inscriptions usually can't be seen with the naked eye, but require a loupe, which is a magnifying eyepiece. Diamond firms and laboratories have distinct formats for their laser markings that may be of help in tracing stolen or recovered diamonds. Contact JSA for assistance in identifying laser marks.
