ClaesDiamonds is a retail merchant of polished natural Diamonds. We also provide consultation services to assist clients in the acquisition process. Obtaining the right diamond can be challenging as it is difficult to find relevant and accurate information.

Our aim is to inform clients in detail and genuinely contribute to the process of choosing a diamond.

ClaesDiamonds provides a high quality and competitive service. This is the result of trustworthy relationships with diamond dealers internationally and efficient practices allowing rapid stock turnover. Our contacts in Antwerp particularly benefit clients wishing to obtain Diamonds of extraordinary cut quality.

The diamond market traditionally has been a ‘push system’ for consumers. The range of choice is therefore often limited to the immediately available stock of a retailer or jeweler. A number of retailers offer a satisfying range of Diamonds although the burden of financing such a policy is forwarded to consumers. At ClaesDiamonds we help clients decide which Diamonds best suit their needs in a professional and thorough manner. Only then we will source and acquire a gem which satisfies the determined criteria. 

Qualifications and Background

Olivier Claes was born in Antwerp, Belgium and relocated to Australia late 2003.

Mr. Claes was awarded the diamond grader diploma by IGI (International Gemological Institute) after successfully completing the required examinations at their headquarters in Antwerp.

In the Diamond industry competence is of crucial importance. Certificates, reports and diplomas are an excellent way to set a minimum standard for quality and service. Nonetheless our position is that a great deal of passion, knowledge and commercial competency is required to maintain a successful entirety.

Ethics and Philosophy

The science of diamonds is complicated. We provide a comprehensive advisory service to allow clients to make a reasonable and informed decision. It is our moral responsibility to ensure appropriate information is available and that important data is not omitted.

We encourage other diamond retailers including jewelers to recognise a duty to inform and maintain a high standard of corporate integrity.

Jewelry Manufacturing

ClaesDiamonds also facilitates custom jewelry manufacturing as the organisation enjoys an alliance with a world class Australian designer.
