Diamond Cut

The cut of a Diamond is the only property, which is totally dependent on man. Cut refers to the shape, proportions, symmetry, and finnish or make of the diamond. A Diamond's Cut will influence the brilliance and fire of the diamond, and is what gives a diamond it's beauty. A diamond that is cut too shallow with respect to its width will allow too much light to pass straight through the diamond, leaving little light to reflect. Such a diamond will appear dull and lacking in brilliance. Alternatively, a diamond that is cut too deeply will allow light to escape from the sides of the diamond and also appearing dull. Did you know that if a diamond is poorly cut, the colour and clarity can not make up for it?

Diamond Colour

Diamonds are found in a variety of colours. The rarest diamonds are ones that have a colourless grading or diamonds with fancy colours such as greens, blues, reds and pinks. The colour of a diamond has a significant impact on its value. The diamond colour scale ranges from D to Z colour, D being colourless down to zed colour which is light yellow. Even though the most valuable diamond is D colour, a diamond which grades G colour through to J colour will appear nearly colourless.

Diamond Clarity

Clarity is a term used to describe the absence or presence of flaws inside or on the surface of a diamond. The clarity of a diamond refers to a diamond's clearness or purity. Diamond's clarity grade is based on the number, size, nature, and location of inclusions and blemishes. Diamonds that have a higher clarity grade are far more valuable in comparison to diamond that contains numerous inclusions.

VVS1, VVS2 Diamonds - Very, Very Slightly Included

Diamond Carat Weight

The weight of a diamond is expressed in carats, this is the weight of measure that the diamond industry uses to weigh diamonds. One carat is divided into 100 points. A diamond weighing one quarter of a carat can also be described as weighing 25 points or 0.25 carats. Carat is often confused with size of a diamond even though it is actually a measure of weight, a diamond's size is measured by fractions of millimetres.

Diamond Certificates

Microscope A diamond certificate is a blueprint of a loose diamond. A diamond certificate can also be called a diamond grading report or diamond dossier . The diamond certificate documents the diamond's exact measurements and weight, as well as the details of its cut and clarity. It precisely points out all the individual haracteristics of the stone, inclusions and any flaws. A diamond which is certified provides consumers with confidence, security and increases comfort levels while making a decision on which diamond to purchase. Wholesale Diamonds choose to only sell certified diamonds that have been independently graded by DCLA, GIA, HRD, or AGS. We do NOT sell diamonds with EGL Certificates.

Diamond Laser Inscription

Laser Inscription Viewer Laser inscription is the use of a very fine precise laser beam to write a grading report number, or customised personal message on the girdle of a diamond. The laser inscription is totally invisible to the naked eye, and can only be seen with a magnifying loupe or a special diamond inscription viewer. Laser inscription provides instant verification, added security and peace of mind when making a diamond purchase.

Diamond Fluorescence

Diamond Fluorescence refers to how a diamond responds when subjected to ultra-violet light. Some diamonds, when they are exposed to UV light, glow different colors. Some diamond merchants and jewellers will tell you that fluorescence is bad. The truth is that fluorescence rarely affects a diamond's sparkle and brilliance. In lower coloured diamonds fluorescence has the ability to make them look whiter and more colourless. Fluorescence in diamonds ranges from faint to very strong, and the most common fluorescent color is blue.

Diamond Hearts & Arrows

Hearts and Arrows is the term that is used to describe round diamonds that display a complete and precise Hearts and Arrows pattern with a total optical symmetry. Diamonds with a true Hearts and Arrows pattern are extremely rare. Hearts and Arrows diamonds produce excellent brilliance, fire and scintillation. It is important to note that all diamonds display a Hearts & Arrows pattern to a certain extent, even poorly cut diamonds. Unfortunately the Hearts & Arrows term has loosely used by jewellers and diamond merchants as a marketing and branding term in order to entice consumers. Viewing Hearts & Arrows
