Verification, authenticate


DCLA can verify your diamond against the diamond grading certificate you purchase it with, or a diamond which you are selling. DCLA will confirm that the diamond matches the grading certificate, whether it is a DCLA Diamond Certificate, or a certificate issued by another internationally recognised laboratory*. We will also check that the diamond is unaltered or damaged in any way.

DCLA can verify both loose diamonds and most diamonds mounted in jewellery. Please note, in some cases we may need to request a diamond be removed from its setting in order to perform a conclusive verification.

Escrow & verification service

In order to protect the Australian public, the DCLA and Escrow Australia Escrow & Verification provides a service eliminating the major risks associated with purchasing diamonds over the Internet.

Although buying a diamond on the Internet can result in significant savings, it also comes with additional risks namely:

  • The diamond supplied does not match the certificate listed on the site
  • The certificate is inaccurate or forged
  • You make the payment but don’t receive the diamond
  • The diamond has been subjected to an undisclosed treatment to improve its colour and/or clarity
  • The diamond is not natural or is a simulant

As diamonds are of high value and require specialist knowledge, DCLA Escrow & Verification not only provides an escrow service, it also has the diamond assessed by the Diamond Certification Laboratory of Australia (DCLA). If the diamond does not match the advertised specifications, your funds are returned to you and the stone is returned to the seller.

The Escrow & Verification service is so successful, eBay Australia has agreed to offer it as a method of payment for diamonds transacted on eBay Australia.

A Simple and Secure Process Supports Every Transaction.

*For certificates issued by other international laboratories, DCLA verifies only that the diamond matches the accompanying certificate. DCLA can not and will not verify or guarantee the accuracy of grading on a certificate issued by a laboratory other than DCLA.

Are Diamonds traceable ?

Diamond traceability refers to the ability to track the journey of a diamond from its source to the market. This includes tracing the diamond’s origin, the path it takes through the supply chain, and the ultimate destination where it is sold to consumers.

Diamond traceability is important for a number of reasons. For one, it can help ensure the ethical and sustainable sourcing of diamonds, by allowing for greater transparency and accountability in the supply chain. This can help prevent the trade of conflict diamonds, which are used to finance armed conflict and human rights abuses. Additionally, diamond traceability can help provide assurance to consumers that the diamonds they purchase are of high quality and have been sourced responsibly.

The diamond industry has established various initiatives to promote diamond traceability, including the Kimberley Process Certification Scheme, which aims to prevent the trade of conflict diamonds, and the Responsible Jewellery Council, which sets standards for responsible sourcing practices in the industry. Additionally, some diamond producers have implemented blockchain technology to enable the secure tracking of diamonds throughout the supply chain.

Certification is another key aspect of diamond traceability. By obtaining a diamond certificate, which includes a record of the diamond’s characteristics and its journey through the supply chain, consumers can be assured that the diamond they are purchasing is of high quality and has been sourced responsibly.
Overall, diamond traceability is an important aspect of the diamond industry, as it can help promote responsible sourcing practices and provide assurance to consumers about the quality and authenticity of the diamonds they purchase.

While it may not be possible for an individual to physically track a diamond from the source, certification and other industry initiatives can help ensure the ethical and sustainable sourcing of diamonds, as well as provide assurance to consumers about the quality and authenticity of the diamonds they purchase.

One technique used to determine the origin of diamonds is through the analysis of their chemical composition. Diamonds from different geographic locations can have different trace elements and isotopic compositions, which can be used to identify their origin. For example, diamonds from different mines in South Africa can have different isotopic signatures.

Another method to determine the origin of a diamond is through the use of spectroscopy, which involves analyzing the unique spectral characteristics of a diamond. This can provide clues about its origin and the geological conditions under which it formed.

It’s worth noting that while these techniques can provide clues about a diamond’s origin, they are not foolproof and may not provide a definitive answer in every case. Nonetheless, advances in technology and the diamond industry’s commitment to responsible sourcing have made it increasingly possible to track and trace diamonds from their source.
