Fluorescence

Diamond fluorescence is a form of illumination that is created when a diamond is exposed to ultraviolet (UV) light. It is undetectable to the eye under most lighting conditions but under UV or black lights, fluoresced diamonds will emit a soft colored glow. Fluorescence is graded as either: none, faint, medium, strong or very strong. Blue fluorescence is most common, but diamonds can also fluoresce white, yellow, or orange (among other colors). Diamonds fluoresce a different color depending on the trace elements found in the matrix of the diamond crystal. In regular light conditions, fluorescence usually has no effect on a diamond's appearance. However, strong blue fluorescence can make a yellow colored diamond appear whiter, but in rare cases, it can make a diamond milky or oily. This milky or oily effect only applies to a small number of strong and very strong fluorescent diamonds. The milky appearance reduces a diamond's price, but can also negatively affect the diamond's brilliance.

But according to a GIA study, the average observer could not detect any difference in color or transparency when viewing diamonds with fluorescence. Fluorescence does not harm the diamond or the wearer.

Advice: For diamonds in the near colorless range (G, H, I and J), faint fluorescence should be considered a neutral or even a slight positive because it can improve the appearance of the diamond. For J or K colored diamonds, medium fluorescence can often be warranted to accommodate a bigger diamond for the same dollars. For colorless (D, E and F) diamonds, we recommend no fluorescence (unless a diamond with exceptional cut and size for the price can be obtained with faint fluorescence).

Laser Inscription

A laser inscription is a name or number that is burned onto the diamond girdle to help identify the diamond. The inscription is similar in appearance to an engraving in the sense that it has been etched or burned on the surface, however, the inscription differs from engraving because it is deep within the diamond. Laser inscriptions on a diamond's girdle add a degree of security, in case you ever need to have it cleaned or repaired. The black seen on the laser inscription is actually burnt carbon remnants left over from laser burning. After the diamond is mounted, the jewelry is cleaned with ultrasonic and steam cleaning (which removes the carbon remnants), making the inscription appear white or clear. Ultrasonic and steam cleaning does not affect the stone's laser inscription, but it makes viewing the inscription more difficult under a loupe. Laser inscription can be more easily observed through a special microscope.

At In Style Diamonds we offer an extensive amount of laser inscribed diamonds that are accompanied with laboratory certificates. These lab certificates or reports contain the certificate number that is branded on the diamond's girdle. We offer laser inscribed diamonds to provide our customers with the adequate protection they need. This number is only visible under magnification. All of our laser inscribed diamonds are provided with their original certificates. As an In Style customer, you can always be certain that the diamond you are wearing is the same diamond described on your certificate. That way you are able to purchase our diamonds with confidence.
