Who are we ?

The company EFIMEX E.I.R.L led by Clément Duret created the site Gem-Pro.com in 2019. The company (French) is based in the south of La Reunion (French overseas department) and is located 900 kilometers, an hour and thirty minutes flight from the capital of Madagascar (Antananarivo). This geographical proximity allows us great possibilities of supply and a strong reactivity as for the new deposits which would be discovered.

Formerly mineral and fossil trader from the big island for almost a decade (where I was going collecting directly materials on site), I was able to export via the internet in almost every country in the world. Over time, I acquired a solid knowledge of minerals and fossils, their origins, their geology, whether in their raw or worked form. I gradually became interested in precious gemstones and fine facets and/or for jewelry and collection, patiently and meticulously constituting a stock of various quality stones from the Red Island and other countries of the world.

At the end of 2017, I decided to specialize exclusively in the field of faceted precious gemstones and I gradually imagined the creation of gem-pro.com. A bilingual online sales website (in English and French) with an international goal where we could find quality stones, selected, and who would offer the best service and value for money to customers.

All products that we offer for sale on the Gem-Pro site are 100% natural (unless otherwise stated) and are offered in short circuit (collected by us directly in Madagascar).

After more than a year of work patiently ordering data, photos and features in a modern and friendly site, I am pleased to present the fruit of my work.
