Diamonds

Cubic Zirconia (CZ) is a synthetic gemstone that is often used as a diamond simulant.

The diamond culet is the flat surface at the very bottom of the diamond, specifically at the pavilion’s tip.

The diamond crown height percentage refers to the ratio of the height of the crown (the top portion of the diamond) relative to the total depth of the diamond.

An internal crystal in a diamond refers to a type of inclusion (a naturally occurring characteristic inside the diamond).

A diamond crown refers to a piece of jewelry, often a tiara or headpiece, that is adorned with diamonds and designed to be worn on the head.

The term “diamond crown angle” typically refers to the angle at which the crown of a diamond (the upper portion above the girdle) is cut.

The crown height of a diamond refers to the vertical measurement of the crown portion of the diamond, which is the area above the girdle (the widest part of the diamond).

Diamond Colour is one of the most important factors in determining a diamond’s quality and value. DCLA uses an official master set of diamonds to compare the diamond in question and determine its exact colour grade.
