Diamond Education

There’s more to a diamond than meets the eye, two diamonds that look alike at first may, in fact, be very different. Two diamonds of equal size can have very unequal values. The differences between them are subtle indeed. To understand these differences is to understand the 4C’s: Cut, Colour, Clarity and Carat. It is these characteristics that determine the value of a diamond.
When buying a diamond ring you want to ensure its quality and integrity. Design Centre’s diamonds are certified by laboratories recognised worldwide, including GIA (Gemological Institute of America) probably the most respected in the world and IGI (International Gemological Institute). This ensures the quality of the diamonds we sell are premium stones.
