About the company.

J.G.J. s.r.o. is a newly established company, which has a vast experience from previous activities that were under a different brand name since 1997. Company renovation and services innovations were necessary due to increasing market.

A bright future is predestined thanks to great references from clients as from final customers, manufacturers and tradesmen. The company takes interests in various activities and services as in goldsmith’s and jewelry, precious metals testings, jewelry, jewel stones, precious and semi-precious stones.

We also offer purity tests, compilations of court evidence reports, sales of metallurgy materials, sales of equipment for goldsmith’s and jewelry shops.

The newly opened premises have a convenient location as it is placed in close proximity of The Slovak Hallmark Institute which is a great advantage considering that many manufacturers and trades people meet here.
