Authenticity Gemstones

All our jewellery is made with real natural stones. It is extremely important to us that we only offer real gemstones in our collection. Unfortunately, many fake and/or imitation gemstone jewellery are offered in this industry. We at Zendro have had all our products tested by the Naturalis: Dutch Gemstone Laboratory in Leiden.

In this overview you will find the gemstones in our collection that have been tested.
