DCLA – The Diamond Certification Laboratory of Australia (DCLA)

Sometimes another diamond, is trapped inside the diamond.

Internal diamond crystals are small diamond inclusions or crystals that are enclosed within a larger diamond. These internal diamond crystals can take various forms, and their presence is a common characteristic in many diamonds.

Here are a few key points about internal diamond crystals:

Nature of Inclusions: Internal diamond crystals are typically tiny diamond fragments or crystals that were present in the diamond-forming environment when the host diamond was growing. These internal crystals can vary in size and shape.

Inclusion Types: Internal diamond crystals are a type of inclusion. Inclusions in diamonds can also include non-diamond materials like minerals, other types of crystals, or even gas bubbles.

Impact on Clarity: The presence of internal diamond crystals, like other inclusions, can affect a diamond’s clarity. The size, type, and visibility of these inclusions play a role in determining a diamond’s clarity grade, which is one of the factors used to evaluate a diamond’s overall quality and value.

Grading and Certification: When a diamond is sent to a Internationally recognised gemological laboratory, such as the DCLA, GIA , HRD, AGS or IGI for grading and certification, the presence of internal diamond crystals, as well as other inclusions, is documented in the diamonds grading report.

Visibility: The visibility of internal diamond crystals can vary widely. In some cases, these internal crystals may be barely visible even under magnification, while in other cases, they may be more apparent.

It’s important to note that the presence of internal diamond crystals does not necessarily make a diamond less valuable. The overall beauty and value of a diamond depend on various factors, including the “Four Cs” (carat weight, cut, color, and clarity), as well as the specific characteristics of the inclusions and their impact on the diamond’s appearance.

The invisible engraving that could see you save hundreds of dollars on wedding ring insurance

Diamond grader Roy Cohen is urging Australians to get diamond rings engraved
He argued a serial number on diamond girdle could stop illegal pawn shop sale
Insurance premiums can also be reduced for jewellery inscribed with a code

A romantic marriage proposal is a significant milestone in many people’s lives.

Engagement rings can also cost tens of thousands of dollars and are commonly stolen in home invasions.

Jewellery experts are urging engaged couples to get the girdle of the diamond engraved so they can’t as easily be pawned.

This microscopic serial number could be enough to get the ring returned, and save newlyweds potentially hundreds of dollars a year in insurance premiums.

Roy Cohen, a third-generation diamond grader originally from South Africa, said these minute inscriptions increased the chance of a stolen ring being reunited with its rightful owner.

‘It’s invisible to the naked eye, it can only be seen with magnification but it’s basically a serial number,’ he told Daily Mail Australia.

‘Usually what happens is, at any pawn shop, they will take a jeweller’s loupe and they will actually have a look at the item.

‘If there’s a certificate number on the girdle of the diamond and the diamond’s been sold without the certificate, usually that does raise alarm bells.’

Mr Cohen, the director of Diamond Certification Laboratory of Australia, said engraved serial numbers on diamonds could be checked against a database, arguing this was more effective than leaving a diamond un-engraved and relying on police detective work to find a stolen item.

‘If somebody steals a diamond ring from a house in Sydney and then goes to sell it in Melbourne, there’s no way that they’re going to get found out because there’s not a lot of co-operation between states,’ he said.

His DCLA company began inscribing diamond rings in Australia in 2001, following his move from Johannesburg to Sydney.

It has now formed a partnership with underwriter Woodina to form Certified Diamond Insurance, which only insures jewellery with an inscribed serial number.

Mr Cohen, who has three decades of experience as a diamond grader, vowed customers could save up to 50 per cent off their premiums compared to traditional home and content packages.

A diamond ring worth $10,000 can be insured for $306 a year.

Jewellery is the third most stolen item stolen from Australian homes, after cash and laptops, an analysis of official burglary figures by insurer Budget Direct found.
