Maroke is someplace around #5 in a series of gem designs that are based on an antique gem a friend of mine wanted me to copy so that she could have matching ear rings.It was harder to find rough the right color to match it than it was to work out the design. Just try to find deep green aquamarine these days! After working out the basic design for her gem I continued to play with the design, keeping the basic outline and re-designing the crown and pavilion.

The design can't decide if it is an oval, or a marquise cut. I decided that a compromise was in order and called it Maroke (Mar-Ke with an O for oval in the middle). The cut gives a lot of sparkle for not many facets and is not difficult to execute. Even though the crown appears to be very simple, there is plenty of interaction between the crown and pavilion facets to produce the desired scintillation. Although non-standard in shape, I was able to coax the stone into an oval setting with only a little tweaking.

This is simple to intermediate difficulty. Start with a rectangular preform of the proper dimensions (like 10mm X 14 mm). This needs to be exact. Once the first set of pavilion facets are cut a meet point can be seen at either end of the rectangle for the end girdle meet points. After that the cutting is very straight forward.
