We are a family business and are personally involved in the purchase and sales of our collection. Our products are carefully selected and directly imported from the source. We fly several times a year to the Far East and South America to ensure the diversity of our collection and to provide you with the highest quality at the best price.
Our dedication to our clients, and insight to their needs has made us one of the most respected and trusted players in the industry.
Our Ethical Vision
When it comes to gemstones, the supply chains are often complex. The mining process, cutting and selling of gemstones usually take place in various countries.
At this point, there is no presence of established bodies tracking the origin from mine to market.
However, our years of valuable experience coupled with a profound market knowledge has led to a transparent, and compact supply chain which we are proud of.
We, at Gemstone, carefully monitor the origin of our gemstones. We strongly care for our environment, sustainable employment conditions, and strive to ensure you with fairness, traceability and transparency as it relates to your product requirements- which is our mission.
We envision providing our customers with a high quality, personal and professional service, at all times.
