Here are the names of gemstone cuts.

When a gemstone is cut, it does not mean it is fake. Gemstones are not weak, but they are not too strong either, and can easily be cut by strong metals. Gemstomes are usually cut to make jewellery.

1. Cushion cut/pillow cut.

The cushion cut is a square or rectangle cut with rounded edges and pretty common.

2.  Emerald cut.

The Emerald cut is a rectangle shape with flat sides and step cuts on the corners. (The gemstone does not have to be an Emerald to be cut like this)

3. Pear cut.

As it says it the name, the pear cut is a pear shape with only 1 vertical. Also known as the 'teardrop' cut.

4. Oval cut.

The oval cut is rounded and longer than it is wide.
