Diamond Clarity - Certified diamond network

Diamonds become increasingly rare when considering higher clarity grades. Only about 20% of all diamonds mined have a clarity rating high enough for it to be considered appropriate for use as a gemstone; the other 80% are relegated to industrial use. Of that top 20%, a significant portion contains one or more visible inclusions. Those that do not have a visible inclusion are known as “eye-clean” and are preferred by most buyers, although visible inclusions can sometimes be hidden under the setting in a piece of handcrafted jewellery. Most inclusions present in gem-quality diamonds do not affect its visual performance or structural integrity. However, large clouds can affect its ability to transmit and scatter light. It’s highly important to view and map inclusions with a trained expert, particularly when considering lower clarity grades. Diamond consulting from your diamond broker in Sydney can help you understand all of these nuances. Interesting Fact: European Diamond Grading Labs (such as HRD) do not consider external defects, also known as blemishes, to be graded for clarity. Instead, any external blemish will affect the overall cut, generally impacting the polish or symmetry grade.
