There are a variety of cuts to choose from nowadays, that have varied considerably since the very first experimental cuts that were made by the very first diamond cutters, to the incredibly precise cuts made today with more advance machinery.

In this article we will focus on one particular cut, which cannot be used for all gemstones because of its particularities. Indeed, you would never see this cut in a diamond because it simply would not make it look as brilliant and scintillant as the round brilliant cut does.

And, we will also try to convince you to consider this cut when shopping for your very unique engagement ring!


A cabochon cut is when a gemstone is flat on the bottom side and it is fashioned like a rounded dome on the top part. It is actually shaped and polished in this manner. The dome in itself can be higher or flatter depending on the result you are trying to achieve.

More commonly, cabochons are used in coloured gemstones, where the characteristic put forward is firstly its colour. But also because very often the cabochon shape is safer for more fragile gemstones.

Cabochons are a crucial cut to be used when particular gemstones, such as sapphires or rubies, present a very specific type of inclusions that form an optical phenomenon called Asterism.

This phenomenon is due to many parallel elongated needle like inclusions, that intersect at a particular angle inside the stone. When a moving light shines over the stone, it is reflected by these inclusions creating what appears to be a floating star on the surface of the stone.

It is very important to fashion the cabochon in the correct direction in order to best display this effect. It is a very unique and stunning optical phenomena which is more and more searched for.
