The gemstone world
Stop relying only
on a seller's word.
In gemstones, small differences — natural vs. synthetic, treated vs. untreated, genuine vs. simulant — can completely change the meaning and value of a stone. This program gives you the foundation to ask better questions, read the evidence and understand what you are looking at.

gemology training
One of the world's largest industries. Almost no one trained for it.
The Graiki Institute curriculum was developed by a gemologist formally trained at SSEF — the Swiss Gemmological Institute — one of the world's most recognized gemological institutions. This is not a hobbyist course. It is a structured professional program built to the same standard as elite gemology training, made accessible for the first time.

The first protection is education
A certificate, a sales pitch or a beautiful photo is not enough. You need to understand the language of gemology: treatments, inclusions, optical properties, species, origin claims and documentation. That foundation helps you become a more confident buyer, collector or professional.
Built to make the first step easier
Foundation in Gemology is designed to give you the core structure first: the vocabulary, concepts and evaluation logic you need before moving into advanced training, expensive tools or higher-risk purchases.
