    The benefit of a purchasing a certified stone lies in the knowledge that the purchaser can take assurance that they know what they are buying. A certificate is like an identity card, which proves exactly what the stone is. Besides the personal comfort that a buyer gets with a certificate, it also makes for a much easier process for obtaining insurance and should you ever decide to sell your diamond, or trade up to a different stone, the process is much easier if you have a certificate. The certificate is similar to a stamp or seal that denotes the authenticity of an item. As in art, a signed painting is worth more than an unsigned as there is no question of its origin.

    GIA stands for the Gemmological Institute of America, AGS Stands for America Gem Society and EGL Stands for European Gemmological Laboratory. Each one of these non for profits organizations offers an extensive array of services for professionals and consumers. Each offers educational programs, grading, appraisal services and ongoing support to the jewellery industry.

    The GIA is generally accepted as being of the laboratories that will apply more stringent criteria when grading stones, whereas the AGS and EGL may not, although the AGS is highly regarded on grading of round diamonds. On the whole however, the GIA is generally accepted as setting the highest standards in diamond grading. At The Diamond Guys we mostly prefer to sell GIA certified diamonds in keeping with our own internal standards of selling the best possible diamonds and jewellery to our clients. You may find that a stone graded by the GIA will be graded lower than that same stone is graded by the EGL, because of the fact that the GIA uses stricter grading measures.

    Both gold and platinum are precious metals. Gold is more common than platinum and most of our stock items are made in 18KT gold. Platinum is a pure white metal, and many people view it as being the more noble of the 2 metals. It is more expensive, rare and durable than gold. White gold is made from yellow gold, and other alloys which give it its white appearance. It is possible with time that white gold becomes discoloured, and you may need to have your jewellery undergo a process called rhodium plating to reinstate the clean white appearance. This is usually only required every 3 to 5 years.

    Yes, we will provide a credit towards an upgrade. Bring your diamond into our showroom for a free appraisal and we will gladly trade your stone if you agree. (Conditions Apply)

    Your choice of setting should be determined not only by the appearance of your ring but also by your lifestyle. Bezel set (where the stone is set into a continuous frame of metal) is a setting which provides the most protection to the stone. This type of setting is more robust and tends to last better under normal wear and tear circumstances. If for example you enjoy wearing your ring whilst gardening, or partaking in physical activities such as sports, you may want to seriously consider a bezel set over a prong setting. Prong settings are preferred in rings where you wish to show your diamond more prominently. In prong setting the diamond is held up higher in the rings, giving it the appearance of being larger. Prong settings are subject to more wear and tear than bezel settings.
