A cabochon is a gemstone which has been shaped and polished as opposed to facetted. The resulting form is usually a convex top with a flat bottom. Cutting "en cabochon" is usually applied to opaque gems, while facetting is usually applied to transparent stones. Hardness is also taken into account as softer gemstones with a hardness lower than 7 on the Mohs hardness scale are easily scratched, mainly by silicon dioxide in dust and grit. There are five basic styles of cabochon cuts: single, double, lentil, hollow, and reverse. The general outline, or shape is circular, oval, rectangular, heart-shaped, or irregular.
We have mentoring instructors who will be able to assist beginners and new members to our club on Tuesday, Wednesday, Thursday nights, Friday and Saturday's. You are given three stones to work on in the lapidary room with a mentoring instructor to assist you along the way from start to finish.
We also run from time-to-time courses in making a cabochon and well as competitions in our clubhouse.
