Our company endorses "April Dream," a project by PR TIMES that aims to make April 1st a day for companies to announce their dreams. This press release represents the dream of "HOUSE GEM ATTENDER Co., Ltd."
HGA (HOUSE GEM ATTENDER) Instructor: Kuniyoshi Hasegawa
"Do you know the true value of your gems?"
"Is that gemstone authentic?"
Can you confidently answer these questions?
Even among those working in the gem industry, very few can correctly identify the type and value of gemstones.
The current situation is that retailers trust wholesalers' words and sell gems without sufficient appraisal.
Blind reliance on experts and wholesalers with only fragmented knowledge, and an industry structure where transactions occur without knowing the true value.
Kuniyoshi Hasegawa strongly wishes to change this situation.
HGA Instructor: Kuniyoshi Hasegawa
HGA, operated by HOUSE GEM ATTENDER Co., Ltd. (Headquarters: Gifu City, Gifu Prefecture; Representative Director: Kuniyoshi Hasegawa), is an online training course for gem dealers, where you can learn world-standard gemology (FGA/DGA) from home.
Kuniyoshi Hasegawa is an active gem dealer who became independent at the age of 20 and has been dedicated to gems for approximately 20 years.
He commuted weekly from Nagoya to Tokyo and successfully obtained both FGA (Fellowship of the Gemmological Association) and DGA (Diamond Diploma) qualifications from the Gemmological Association of Great Britain, widely considered the world's most difficult, on his first attempt.

"All that I have gained, for you."
With this philosophy, HGA was launched.
Students are provided with a professional appraisal kit (12-piece set), 12 types of starter stones, natural melee diamonds, and even the gem sales strategies Hasegawa has built over 20 years.
We offer a practical curriculum that enables individuals with zero knowledge to become active "gem dealers."

12-piece Starter Stone Set
All of these are presented to students free of charge.
・For gem lovers to be able to discern true value.
・To possess correct knowledge and truly enjoy gems.
・For gemology to be learned as "general education," like music or art.
HGA is seriously committed to realizing this dream.
Three Steps to the Future
Step 1: Professionals with world-standard knowledge in gem and jewelry stores nationwide.
Currently, very few gem dealers in Japan hold both FGA and DGA qualifications.
Through HGA, we will produce "gem professionals with world-standard knowledge" for gem stores nationwide, creating an environment where consumers can visit stores with confidence.
Step 2: Nationwide expansion of "Gem Appraisal Experience Events" for consumers.
We will hold events where the general public can experience identifying gems using an actual appraisal kit.
We aim to spread the "joy of discerning for oneself" and deepen understanding and interest in gems.
Step 3: From specialized knowledge to "general education" in gemology.
We believe that gems should not be exclusive to a few experts or the wealthy, but rather more accessible and enjoyable for everyone.
We aim for a society where knowing how to view and value gems is widely recognized as "general education," like music or art.
To achieve this, we plan to establish our own certification system to make true gem professionals visible.
We will work to create an industry-wide environment where consumers can feel confident that "this person is a trustworthy gem dealer."
HGA Study Sessions and Social Gatherings
HGA Offline Study Session
Although HGA is an online course, we regularly hold offline study sessions and social gatherings.
Holding actual gems, students discuss and inspire each other.
Such "real connections" are also something we value.
We will continue to provide an environment where individuals can grow together with like-minded peers, rather than learning alone.
Message from Kuniyoshi Hasegawa
"Gems are miracles created by the Earth over hundreds of millions of years. If more people can correctly convey their value, it will create a world where gem lovers can enjoy them with greater peace of mind. I want to generously pass on the knowledge and experience I have built over 20 years, and the world-standard gemology I acquired through immense time and effort, to the next generation. I want to cultivate as many 'colleagues' as possible to enhance the trustworthiness of the entire industry. My dream is to create a world where people with correct knowledge, not just internet rumors, can truly enjoy gems."
