Our
courses

Using our specialist facilities and supervised by the best experts, the Netherlands Gem Laboratory offers the following courses.

Practical Gemmology

The Netherlands Gem Laboratory offers the four-day Practical Gemmology course for people who are starting out as jewelers or want a solid grounding of practical knowledge about gemstones. In a few short days, the course covers the gemstones (natural, synthetic, imitation) and pearls that are available on the market.

Participants are provided practical tools to recognize the most common gems and pearls. This offers a unique opportunity to practice extensively with the requisite tools under professional supervision.

The Practical Gemmology course does not require special training and participants receive a certificate as proof of participation at the end.

  • Length: 4 days
  • Time: daily, 9:30am - 4:30pm
  • Date: Monday 27, Tuesday 28 June and Monday 4 and Tuesday 5 July 2022.
  • The four-day course costs € 600 (excl. 21% VAT), includes course materials and use of the instruments on site. Lunch is not included in the price.
  • Location: Naturalis, Darwinweg 2, Leiden

Gemmology Refresher Class

Designed especially for professionals (such as jewelers and goldsmiths and silversmiths) who work extensively with gemstones, the Netherlands Gem Laboratory offers a one-day refresher class. Our experts bring participants up to speed on the latest developments in the field and you can try out the latest techniques yourself.

It can be difficult to tell real from fake. Where are your limitations in this regard? In this refresher course we show you the latest handling methods for gems to keep you current in this area. With an emphasis on diamonds, rubies, emeralds, and sapphires, you'll test your professional skills to find out when you can identify a synthetic product, and when not. That way, you'll know in which cases you should turn to a specialist laboratory like ours.

Special master classes

Gem Laboratory clients may be interested in learning more about a particular topic. For them, we offer special master classes. If desired, the laboratory can organize a master class for a private group. This assures you optimal guidance, tailored to your needs. The Gemmology Refresher Class requires basic knowledge of gemology or prior gemmology training, such as FGA or FEEG.

  • Length: 1 day
  • Time: 9:30am - 4:30pm
  • Date: to be announced.
  • Location: Netherlands Gem Laboratory, Darwinweg 2, Leiden
  • Costs: the one-day Gemmology Refresher Class costs €180 (excl. 21% VAT), includes course materials and the use of the instruments on site. Lunch is not included in the price.
