  • 4C’s Diamond Education

    In 1953 the Gemological Institute of America (GIA) developed a universal diamond grading standard, known as the 4C’s (cut, colour, clarity and carat weight). The creation and development of an international accepted diamond grading system was a major break through. Diamond purchasers now know exactly what type of diamond they are purchasing based on the 4C’s grading system.

    At Hempen Jewellers 90% of all diamonds sold of .50 carats and greater come with a GIA diamond grading report. This is extremely important as GIA certificates are a blue print of a diamonds quality and characteristics. GIA is a research and educational institute and does not represent diamond sellers or sell diamonds. Accept no other diamond grading report.

  • Cut

    The most important of the 4C’s cut determines the brilliance and beauty of a diamond. Diamonds cut to ideal proportions display brilliant reflections of light and sparkle. GIA diamond grading reports describe cut grades as – Poor, Fair, Good, Very Good and Excellent. Hempen Jewellers strives to sell only the most brilliant diamonds of high cutting grades ensuring maximum sparkle, brilliance and beauty.

  • Colour

    The most desirable diamond colour is actually no colour at all. Diamond value is established the closer a diamond reaches the colourless scale. Diamonds that show signs of colour generally display hues of brownish or yellow tones. Hempen Jewellers offers a wide selection of loose diamond in the colourless and near colourless scale (D-H).

  • Clarity

    Diamonds are very unique, no two are the same. Most diamonds have some form of an impurity or flaw within. Clarity is graded using magnification of 10x to determine a diamonds clarity. Diamond clarity ranges from flawless to I3.

  • Carat

    Carat is a measurement of weight. One fifth of a metric gram equals 1 carat. Half of a carat is described as 0.50 carats, a carat and a quarter is 1.25 carats and so forth. Generally diamonds with higher carat weight demand higher prices however carat weight can be the least determining cost factor if the other 3C’s are on the lower end.
