According to the cross-sectional shape of convex gemstones, convex cuts can be divided into the following five categories.

(1) Single convex cut, the top of the cut is a convex arc, and the bottom is flat.

(2) Convex cut of lentils. The upper and lower convex arcs of the cut are the same, and the height is relatively low, which is lentil-shaped. Opal stones sometimes use this cut.

(3) Double convex cut. The characteristics of this cut are similar to the convex cut of lentils, but the upper convex surface is higher than the lower convex surface. Star gems, opals, and moonstones often use this cut.

(4) Hollow convex cut, the cut is based on a single convex cut, a concave hollow is dug up from the bottom. This cut is mostly used for gems with deep color and low transparency. After digging a hole, make the top thinner to increase the transparency and the color becomes brighter. Jadeite is often used for this cut.

(5) Concave cut, this cut is also often used to combine gems. Its basic shape is the same as that of a single convex cut, except that a concave surface is dug down on the top convex surface in order to set another one in the concave surface. More precious gems, such as star gems or opals.
