How to select Facet Grade Raw Emerald?
Choosing a facet grade rough emerald is dependent on a few factors:
- A good color that will really enhance demand
- A good shape that’s blocky, chunky, or rounded. Fat ones tend to yield badly.

To facet emeralds, you need to choose cuts, with the most common being the emerald cut. That’s a triangular shape.
You want to cut this to the shape decided, using either a jigsaw or a circular saw if there are flat lines. You want a blade with a hardness that will cut this, such as a diamond blade.
Facet this using a machine called a faceting machine too. Attach the emeralds to each of these facet pegs, either with glue or clamps. Direct these plates all the way down towards the gem and the angles you plan to facet on these with a slow, steady level of pressure.
Polish this by using belt sanders, and then try to ensure you use the highest grade plates, removing every scratch you can from these emeralds. If you want a more matte finish, skip that.
At this point, you can oil the stone, however, be mindful of the fact that oiling this does make it brighter and shinier, but it’s regarded as devaluing the stone. That’s because it does make this reactive, and it does wear over a period of time.
With that said, there are a lot of different aspects of faceting that can really stand out.
