Size: 12 mm.
One unit / package contains one cabochon (the finished jewel is only an inspiration).
You can find tutorials for this cabochon here.
I do my best to show you the exact colour of the products, however, due to slight differences between batches and due to the settings of your monitor there can be a difference in the exact shade of colour.
Due to technological circumstances I can’t influence, the exact colour you receive can be slightly different then what you see on the monitor.
