Does Your Diamond Engagement Ring Have Enough Bling?

How does a diamond reflect and deflect light? You can learn more about these properties by using an angular spectrum evaluation tool, or ASET, for short. This simple device is used by gemmologists to see how a diamond handles light. Since a diamond’s beauty comes mainly from its brilliance and fire, it is important to better understand the details about light performance and the quality of a gem’s cut.

How ASET is Used

Besides being a reflector tool, ASET also contributes to the grades of cuts that are used to assess diamond quality. The concept of using the device is very basic. By viewing a gem through the top hemisphere, painted with various colours, the observer can make a clear assessment about a diamond’s ability to reflect light. The tool also indicates the spots of light leakage, or where the diamond does not return light.

Angular Ranges

The device also delineates specific angular ranges. These ranges are made up of 0 to 45 degrees of colour, coded in green, 45 to 75 degrees coded as red, and 75 to 90 degrees coded in blue. Due to the fact that the environment is normally lit by an overhead light or sunlight, the most direct form of light entering a diamond will usually come from higher angular ranges.

Low angled light is prone to reflect off objects, and therefore is less intense than high angled illumination. Light from above, or the highest angular range, is blocked by the head when a diamond is observed closely. This light, per ASET, is colour-coded blue.

Diamonds with Round and Brilliant Cuts

ASET observances of engagement rings in Houston, are undertaken in order to identify the clarity of the diamond being placed on your engagement ring. And because of this attention to detail you know that you’re buying into a diamond of brilliant quality.

A benefit to this technique is that it can be applied to any diamond no matter what size or shape it may be. Meaning you can get on with the task of choosing the right style whilst leaving the intricate details down to the experts.

Part of Diamond-grading Technology

Due to its being used in conjunction with grading, the ASET tool has also been integrated into a software programme. In turn, the software application is able to render ASET images of a diamond. Reports are also used that provide ASET light maps. As a result, ASET applications and theory represent a powerful, yet fundamental, approach for assessing a diamond’s light.

One popular reflector-type tool, that operates similarly to the principle used by ASET, is a scope reflector. When using this rudimentary light assessment tool, all light returning to the eye appears in red whilst obscuration is shown in black, and light leakage in white.

The ASET tool, however, is an excellent prognosticator of a diamond’s visual performance. This type of comprehensive evaluation should be used regularly by diamond shoppers. If customers could see ASET images up-close, they could better understand the light-handling abilities of the diamonds they want to buy. However, you can also gain a helpful perspective by considering a diamond’s grade. ASET just makes it easier for you to understand how diamonds are assessed for their “bling.”
