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 2005, Adrian Smith, FGA, joined the Quantum Leap family and now serves as a consultant. Adrian is an expert valuer whose unrivaled qualifications support over thirty years trade experience in the UK.

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 has been rewritten to run on Microsoft Windows 8 and with 64 bit coding continues to implement the latest and best technology continuing to streamline the production of jewelry appraisals for the discriminating jeweler and independent appraiser.
