The Five C's of Diamond Buying

Most people have heard of the 4 C's of Diamond Buying. It is common knowledge that all diamonds are graded for their cut, color, clarity and carat weight

But did you know that Renaissance Diamonds introduced another "C" into the equation: Created. Renaissance Diamonds offers lab-created, fancy colored stones at a fraction of the cost of mined diamonds. Our created diamonds are identical to mined diamonds in every way except their origin. The diamond creation process is outlined below:

The 5 C's are identified on all of our diamond buying certificates. Every Renaissance lab-created diamond is certified by the International Gemological Institute (IGI) and the Gemological Institute of America (GIA) and all 5 C's are taken into account during diamond grading.

Growing Incidence of Undisclosed Treated Diamonds in Australia

DCLA has seen an alarming increase in the number of treated diamonds being submitted as natural diamonds to the laboratory for certification.

It should first be said that diamond treatments are neither good, nor intrinsically bad in and of themselves. There is nothing wrong with buying a treated diamond, provided that the treatment is fully disclosed and that you pay the appropriate price for the diamond. Because of their lower cost and value, treated diamonds can allow a person to buy a diamond that appears to be of a higher quality than it truly is.

However, too often the presence of such diamond treatments is concealed. Whether this deception is by intent or negligence, such concealment is tantamount to fraud.

Not only does artificially treating a diamond significantly reduce its value, but most diamond treatments are unstable and reversible. For this reason, all internationally accepted rules for diamond grading forbid the certification of treated diamonds. An extremely disturbing discovery just recently in the DCLA Laboratory was that of a coated diamond accompanied by a certificate from a supposedly legitimate Australian ‘laboratory’.

Members of the diamond industry have a responsibility to consumers to convey accurate and transparent information, and each individual that handles a diamond as it moves down the diamond pipeline from the mines should be held accountable for making known any treatments that a diamond has undergone.

It is deceptive and unfair to fail to disclose treatment of a diamond when it has a significant effect on a diamond’s value. In its pursuit of consumer protection, DCLA is offering a ‘Diamond Amnesty’ for diamond owners Australia-wide – any diamond brought in with its matching diamond grading certificate will be verified for grading accuracy and tested to ensure that it is natural and free of treatments. This service will be provided free of charge.
