This gemstone is flawless and you can see that clearly as there are no inclusions.
I saw this fluorite and loved it. The square shape is unusual and adds a certain luxury feel to this piece. The carat weight is 10.27 so it is quite large. I set this into a lovley sterling silver double claw pendant.
The fluorite here also has slight colour change properties and moves from a bright green in daylight to a darker greenish blue at night. It is a subtle change though.
The chain here is included
