Greetings from GCA
We are a small certified gemstones shop market,
operating out of Brussels since 2018.
We have a large collection of gemstones certified by
a recognized international laboratory,
including all kinds of gemstones as your requirement.
We take care to have the best quality luster and facetted gems as we can.
Visit our store through that website constantly updated.
Feel free to ask for a wholesale lot of gemstones
and recut and polish already facetted gems.
Don’t hesitate to ask for information on gemstones, origin, and certificate
