VAT is not applicable.

We will cover observation and instrumentation which helps us identify laboratory-grown diamonds. Equipment includes Presidium ARi, Presidium SDSII, Gemetrix Jewellery Inspector, Gemetrix StrainView. Topics will include: Observation, magnetism, UV reactions, crossed polarised filters (CPF), screening equipment, testing melee and discussions on advanced equipment. 

  • A minimum of 35+ laboratory-grown diamonds plus melee stones will be available.
  • Basic gemmological equipment is available to loan for the day.
  • Attendees leave with printed handouts of lessons and test results.
  • Classes are limited to 12 participants.
  • Hosted in the beautiful architecture of The Goldsmith Centre in Farringdon, London.
  • Lunch and refreshments included.

  • This course is CPD accredited.
  • Attendees will receive CPD points and a certificate of attendance.
  • Attendees will have an option to attend a "recap day" in 2022 priced at £195.00 to gain further experience testing laboratory-grown diamonds.

There is nothing like this course out in the market right now! There are two others available in the U.K. One is priced at £650pp. The other is £295pp and does not offer this range of sample stones, access to equipment nor offers CPD points. This is the only laboratory-grown diamond course with a Central London location.

Pre-requisite: Participants must have gemmology/gemstone experience. Good use of loupe/tweezers/microscope and lighting is a must. A gemmology/diamond diploma-level understanding of laboratory-grown diamonds is a minimum. Graduates of The Gem Academy courses on laboratory-grown diamonds are perfectly suited to this one-day workshop.

This workshop is the perfect compliment to The Gem Academy's online courses: The ultimate online course for laboratory-grown diamonds and The retailer's guide to laboratory-grown diamonds.

Want this workshop to come to you? I also offer this course as a travelling workshop nationwide to come to your place of work. This is a good option for those with 4 or more persons requiring this practical training. Maximum of 14 attendees in one day. Email to enquire further.
