COVID-19 Pandemic Notice

As we return to our operations, we have put in place heightened safety protocols for your health and peace of mind.

Aside from the implementation of social distancing, mandatory thermal checks, foot bath mats at the front door, compulsory wearing facemasks and cashless transactions we also have installed acrylic partitions on working tables in our classrooms and lab rooms. Plus frequent sterilization of Student’s Aid Kits (eye loupe, tweezers, diamond hole gauge and gem cloth).


Gemlab Philippines, the leader in jewelry appraising, gemology and jewelry design education in the Philippines, established in 1986 by Directress Lucille Esperame-Bocobo. The company's goal is to help address the problems in the pawnshop & jewelry industry by teaching the correct basics of grading and identification to ensure a sound appraisal, attract more customers and pawners, help sell more, save & protect the goodwill of the business and to establish one's reputation as a trusted professional locally and in the international market. We also offer lab services on gold & diamond appraisal, diamond grading and gem identification.

Gemlab currently offers the following courses:
  • Basic: Jewelry Appraising and Pawnshop Operation & Management(includes Gemology 101 Prerequisite on Diamonds & Colored Stones)
  • Basic Gemology on Diamond Education (Diamonds, 4C’s, Imitations, Treatments) &Appraisal 
  • Advance: 2 courses in Gemology (Diamond Grading and Colored Stones & Gem Identification)
  • Jewelry Design
  • Fine Jewelry Manufacturing
  • Fine Jewelry Plating
Our students learn the international standard of grading, identification and techniques that can only be obtained in gemological institutions abroad, particularly in the USA, Europe and their branches in Asia. 

Our difference is we limit the size of the class to a small number of participants only from 1-2 for tutorial format and 4-8 for the group.

Each student must finish all the school's requirements working on over a hundred specimens in the JA course alone. Passing the written and final examinations for skill development our graduates earn 3 certificates: Attendance, Achievement on ID, and Achievement on Appraisal.

GEMLAB is the only school which has a laboratory equipped with gem microscopes and lab instruments to help study diamonds and gemstones better. This enables students to learn how to grade diamonds and identify stones, their nature and treatments for a sound appraisal.

Our graduates obtain all the necessary information and updates needed to learn or improve on their craft, as well as know the principles of the various kinds of appraisals & work ethics, and are invariably regarded by the public as trusted professionals. And those who attended other seminars locally find our Programs more comprehensive both in content and approach.

We have also been chosen by well known chains of pawnshops in the country to train their appraisers and trainors of their own in-house training programs. That is why GEMLAB has remained the only favoured school in the Philippines for almost four decades now.
