Do you know the true value of your gemstones?

"Is that gemstone authentic?"

Can you answer this question with confidence?

Even people working in the gemstone business, few can correctly identify the type and value of gemstones.

Currently, sellers rely on the word of wholesalers and sell without sufficient appraisal.

Blind reliance on experts and wholesalers with fragmented knowledge, and an industry structure where transactions occur without knowing the true value.

Kuniyoshi Hasegawa strongly wishes to change this situation.

HGA, operated by Gem Attender Inc. (Headquarters: Gifu City, Gifu Prefecture, Representative Director: Kuniyoshi Hasegawa), is an online gemologist training course where you can learn world-standard gemology, FGA and DGA, from home.

Kuniyoshi Hasegawa is an active jeweler who became independent at the age of 20 and has been engaged with gemstones for approximately 20 years.

He commuted from Nagoya to Tokyo almost every week and successfully obtained the double qualifications of the Gemmological Association of Great Britain's FGA (Fellowship of the Gemmological Association) and DGA (Diamond Diploma), considered the most difficult in the world, on his first attempt.
