The DeRocks Story

Our History

DeRocks has been serving our customers since 1981. Our founder Izik Davidov is a diamond expert with over 40 years experience in the diamond and jewellery industry.

At the heart of our business, along with a love of diamonds, are our customers. Our customers come from all over the world and many we’ve worked with for decades—they come back because they trust us and value our expertise. Our experience and care for our customers is the reason why we’re still going strong today.

As one of the original diamond traders in Singapore, we have well-established relationships with our associates around the world. This means you, our customers, benefit from quality diamonds and decades of experience.

We look forward to becoming your family jeweller for life.

DeRocks Difference


DeRocks is unique—unlike other diamond companies, we own every diamond we sell and have personally inspected every diamond that comes into our inventory. We don't use databases of stock from different companies and we don’t sell diamonds on consignment from other retailers. Read more about our quality guarantee.

Quality Guarantee


Our team examines every diamond before we purchase—we inspect every diamond against its certificate to confirm its quality.

The majority of DeRocks diamonds are certified by the Gemological Institute of America (GIA)—the world’s leading authority on diamonds. We also sell diamonds with other certificates when they meet our high quality standards.

Lifetime Guarantee


As part of our commitment to being your jeweller for life, we offer a lifetime guarantee for diamonds 0.30 carats and above.

Sometimes, customers want to ‘trade-up’ their diamond. With our lifetime guarantee, as your circumstances change over time, you have the option to exchange your diamond for a larger carat size.

We’re currently the only diamond retailer to offer a lifetime guarantee. Our two options in the lifetime guarantee include trade-in or buyback.
