Step 1: Selecting the rough opal
The first step in cutting opals is to select the rough opal that you want to work with. Look for opals with vibrant colors and interesting patterns. It's important to choose a piece that is free from cracks or fractures, as these can affect the stability of the stone during the cutting process.
Step 2: Cutting the rough opal

Step 3: Shaping the opal
After cutting the rough opal, the next step is to shape it using diamond grinding wheels. This process involves carefully grinding away the excess material to create the desired shape and form. It's important to work slowly and patiently to avoid damaging the opal.
Step 4: Smoothing and polishing the opal
Once the opal is shaped, it's time to smooth and polish the surface using diamond sanding pads. This step helps to remove any scratches or imperfections and brings out the natural shine of the opal. It's important to use a gentle touch and work in small increments to achieve the best results. The final polish is done with Cerium Oxide. Please see Cerium Blog
