About QLSS

The seeds for Quantum Leap were originally sown in 1978. Thom Underwood, at the time, was a partner in a jewelry manufacturing/showroom business and had just founded a jewelry appraisal company (San Diego Gemological Laboratory) in San Diego, California. Seeking to streamline the time consuming appraisal process, Thom looked towards computerization.

Quantum Leap for DOS was first released to the market at the Tucson Gem and Mineral Show in 1987. In less than two years, Quantum Leap had over 50 users and continued to grow with new features and more users. In 1993, with yet another breakthrough for jewelry appraisers, Quantum Leap released its first Windows version. The user base has continued to grow over the decades.

In 2011 Michael Inkpen, FGA became our UK distributor providing marketing and full time support for Quantum Leap users on the other side of the ‘pond’.

Indeed, in this new millennium Quantum Leap now runs on  Microsoft Windows OS versions 8 and above and continues to implement the latest and best technology continuing to streamline the production of jewelry appraisals for the discriminating jeweler and independent appraiser.
