Girdle
The girdle is the outermost edge of the diamond between the crown and the pavilion.
Growth or grain lines
These can be considered internal flaws, and can often be seen only by rotating the diamond very slowly. They can appear and disappear almost instantly. They appear as small lines or planes within the diamond.
Gypsy Setting
The Gypsy setting is predominantly used for men's jewelry. The band is one continuous piece that gets thicker at the top. The top is dome shaped and the stone is inserted in the middle.
