Cut

Cut is the only ‘C’ in diamond crafting that is controlled by human. A well-cut diamond brings out the full potential of a diamond’s light. However, if a diamond is badly cut, it will not match the fire and brilliance of a lower-grade diamond that has a better cut. So, you can have a diamond that is superior and perfect in colour and clarity, but its value is drastically reduced if the cut is of inferior quality.

An artisan carefully crafts a diamond’s cut based on a set of mathematical formulas. Much like Diamond & Platinum’s signature Estrella diamond, the diamond will internally reflect all light from one mirror-like facet to another and disperse through the top of the stone. A perfectly cut diamond is the most beautiful display of brilliance, fire and scintillation.

A diamond that is cut too deep, or too shallow, loses/leaks light through the side or bottom of the diamond, resulting in less brilliance and, ultimately, value. The finer details of the cut, lie in the proportion, symmetry and polish of a diamond. The cut grade determines 50% of a diamond’s value.

The best is to see this for yourself at a Diamond & Platinum outlet. Ask us, and as they say, seeing is believing!

Proportion refers to a relationship between size and angle, and different facets of a diamond. Proportion determines the light’s path as it passes through the diamond. The better the proportions, the better the light reflection will be, and hence, the more sparkle that will be created.

Precise calculations need to be made to determine the best combination of size and angles, so that a diamond will sparkle to its full glory. It is interesting to note that diamonds that are cut in various different shapes will not carry the same optimum brilliance as the classic round diamond. So, now you can go ahead and dazzle someone with this information about diamond proportions!

A perfectly cut diamond is the most significant and beautiful display of brilliance (white light), fire (rainbow color lights) and scintillation (reflection of lights when the diamond moves).
It has been said that a face that is in perfect symmetry looks more attractive. The same can be said for diamonds! It is indeed amazing that we can draw a lot of similarities between a diamond and humans.

Symmetry is the keyword when it comes to a diamond’s brilliance. Each cut made into a diamond must align at every angle so that it achieves an even display of brilliance, fire and scintillation.

A poor symmetry is the result of misaligned facets, and it leaves much to be desired. This misalignment causes light to be misdirected as it enters and exits the diamond, resulting in poor and uneven brilliance, fire and scintillation.
Here’s another diamond-related term to pick up – polish! Actually, polish refers to the smoothness of a diamond’s facet. A master cutter will polish each facet of a diamond until it is smooth as silk. With great polish, comes sharp and even reflection. As with all other aspects of a diamond, the better the polish, the better the brilliance, fire and scintillation.

diamonds that are not polished well will reflect light poorly and that results in a fuzzy reflection that will be frowned upon by top master cutters.

And there you have it! It all adds up to a diamond’s value, starting from 4Cs to proportion, and right down to symmetry to polish.
