Diamond Education

To get the perfect diamond here are several factors to consider. You’ve read about the 4Cs of diamond education but let us guide you through our 4Cs to help you find the one.

Cut

Far more than simply what shape a rough diamond has been polished into, the cut is the most important determiner of a diamond’s brilliance and light dispersion. Diamond cutting is an art requiring meticulous precision, and knowing how it all works is essential to making the right choice.Read More

 

Carat

Pretty things may come in small boxes, but what’s in those boxes better be big. That is, yes, size does matter. However – carat weight is not the same thing as size – how large a diamond appears is also dictated by other factors such as shape and cut, so it is important to understand carat weight beyond the value it is generally and often mistakenly ascribed.

Clarity

Almost all diamonds have small impurities or “inclusions,” but they are not always visible to the naked eye. The size and location of the inclusions play a significant role in determining the price of a diamond so it is important to understand clarity grades in order to make the most suitable choice.Read More

 

 

COLOUR

Colour grades actually refer to a lack of colour in a diamond, with the whitest grade being D, and that’s D for most desirable. However, even experts sometimes fail to tell the difference between some clarity grades, so unless it’s important for you what the letter on the certificate reads, you can often get away with lower grades.

CERTIFICATION

Ensuring your diamond is certified by one of the leading independent and recognised certification laboratories is essential for an unbiased assessment of the stone’s quality. GIA, HRD, IGI  are the leading grading bodies in the diamond industry, and are listed here in order of strictness. Today, expect most diamonds over 0.20ct to be graded by one of these.

Expert tip 1

As subtle differences in diamonds can have a massive impact on price, if you are offered self-certification or certifications from less stringent local grading bodies, it is generally because the seller can improve their margins by doing so. Please remember the comparison of such diamonds would not be like for like. Always demand a recognised international certificate to create a level playing field.

Expert tip 2

Even amongst the 3 internationally recognised certificates, there are differences. In fact, the diamond industry benchmarks every diamond against the GIA’s (Gemological Institute of America) strict standards. Comparing a diamond with a GIA certificate against an IGI or the weaker EGL is not an equal comparison. So like-for-like colours or clarity grading on EGL would be graded 2/3 grades lower if sent to GIA and therefore should reflect lower prices.

Laser Inscription

The 3 leading diamond certification organisations issue a unique number for every diamond, to protect the consumer. On most new GIA certificates and selectively on some other certificates, this number is laser inscribed in the diamond’s girdle, and can be easily verified with a magnification loop. This assures you the diamond you are buying is the actual one.
