About QLSS

Quantum Leap Software Solutions (QLSS) began its evolution in 1978.  Thom Underwood, was a partner in a jewelry manufacturing/showroom business at the time and had just founded the jewelry appraisal company San Diego Gemological Laboratory in San Diego, California.  Seeking to streamline the time consuming appraisal process, Thom looked towards computerization resulting in QLSS’s Professional Appraisal Software (PAS).

PAS for DOS was first released to the market at the 1987 Tucson Gem and Mineral Show.  In 1993, with yet another breakthrough for jewelry appraisers, QLSS released its first Windows version of PAS.  Over the ensuing decades, PAS remained at the forefront of jewelry appraisal technology with features that provided unprecedented flexibility and stability for jewelry appraisers from around the globe.

In 2011 Michael Inkpen, FGA, became our UK distributor, providing marketing and full time support for PAS users on the other side of the “pond”.

In 2015, after much study of the changing technological landscape, QLSS embarked upon the journey of a complete rewrite that fully embraces the future of computing in the 21st century for yet another “Q”uantum “L”eap in jewelry appraisal software — QL2.  Indeed, in this new millennium QL2 runs in your browser and implements the latest and best technology continuing to streamline the production of jewelry appraisals for the discriminating jeweler and independent appraiser.
