crown | ˈkrau̇n
noun
The facets or portions of a gemstone, located above the girdle
The top of faceted and cabochon gems is referred to the crown. Faceted gems specifically, the crown is considered the area above the girdle. In the general run of things, wearers notice the crown when viewing the “face” of a gem in jewelry. In contrast to diamonds, nearly all colored gems are cut with mixed designs; for instance, the step-cut pavilion rused with a scissor-cut crown is a great example of this. Furthermore, one of the most sought-after mixed-cut designs for colored gems, fuses a brilliant-cut crown with a step-cut pavilion. Additionally, the word 'table' - in relation to jewelry - refers to the flat top of the crown. In many cases, the crown of a gemstone is hauled up; however, in other cases, crowns may be cut flat, high, or concave. In relation to round and oval stones, the crown includes bezel facets, star facets, and upper-girdle facets.
