Collectors Universe's Diamond Grading Unit GCAL Selected by the Government of the Northwest Territories to Provide Services for Its Diamond Certification Program

NEWPORT BEACH, Calif., April 20 /PRNewswire-FirstCall/ -- Collectors Universe, Inc. (Nasdaq: CLCT), a leading provider of value-added authentication and grading services to dealers and collectors of high-value collectibles and diamonds, today announced that its diamond grading division, Gem Certification & Assurance Lab, Inc. (GCAL), has been selected by the Government of the Northwest Territories of Canada (GNWT) to provide Gemprint digital imaging as the unique identification technology for the GNWT's diamond certification program.

The selection of GCAL to provide Gemprint digital imaging is part of the continuation of an existing GNWT program that began in 2001 whereby diamonds are certified, at the option of the diamond manufacturer, by GNWT as being mined, cut and polished in the Northwest Territories. The Gemprint process is a non-invasive, patented identification technology that captures and stores a digital image of the unique refractive pattern that is, in essence, the diamond's "fingerprint." To participate in the GNWT certification program, a diamond manufacturer is required to use GCAL's certification service, which includes a Gemprint digital image of the diamond. GCAL forwards that Gemprint image to the GNWT for inclusion as a part of the GNWT diamond certificate. Each GNWT diamond certificate is signed by the Premier of the GNWT and is provided to the diamond manufacturer and can accompany the diamond through the various distribution channels to the retail counter. Because the Gemprint image for a GNWT certified diamond can be retrieved from GCAL's database at any point in the distribution process for matching to the GNWT certificate, there is an increased level of security against anyone being able to successfully substitute, during the distribution process, diamonds sourced outside of the Northwest Territories for the diamonds that have been certified by the GNWT.

In addition to these services, GCAL will support a co-marketing program with the GNWT to promote diamonds from the Northwest Territories that are certified under this GNWT program.

GCAL plans to market its diamond grading services and related bundled services, such as direct light performance, together with its Gemprint service, to the Northwest Territories diamond manufacturers. According to the GNWT, in 2004, an estimated total of 12.6 million carats or $1.65 billion USD in rough diamonds from the Northwest Territories were processed, although not all of this production participated in the GNWT certification program. Canada is the third largest producer of diamonds in the world. (Source: 2005 Diamond Industry Report, Diamond Facts, Northwest Territories Canada)

GCAL President Don Palmieri commented, "The Canadian diamond program is the most noted verified source program and it is an ideal match for GCAL and the GCAL Five Star Diamond Certificate, since we already include the Gemprint identification 'fingerprint' as one of the five stars from our services."

Chief Executive Officer of Collectors Universe, Michael Haynes said, "Diamonds sourced from the Northwest Territories are becoming more important in the U.S. and world markets. We believe that the combination of the Northwest Territories certification and the associated GCAL Gemprint will increase the confidence of the diamond buyer regarding the source of these Canadian diamonds. This agreement represents another step in our efforts to become a driving force in the diamond authentication and grading market."
