One of the first things I learnt in jewellery making classes was how to bezel-set a cabochon into a ring. Because of that  I went searching for some interesting semi-precious cabochon stones to set into a ring. That's when I fell in love with gemstones and realised what a fascinating hobby lapidary is.  I have some experience in stained glass work so  cutting, shaping and polishing Rough Stones into cabochons seemed like another interesting hobby.

I started doing of research into Lapidary Equipment. I looked at this site www.rockcraftgems.net and figured out that, to start with I would need a Lapidary Trim Saw and a Cabbing Machine.

A Trim Saw is used to cut down rough rocks into slabs which are the flat pieces from which you cut as close as possible to the shape of the cabochon. A lapidary trim saw is a basic machine that uses a Diamond Saw Blade and  has a water or oil  reservoir to lubricate the diamond Saw blade.

A Cab Machine is used to shape and polish the rough slabs into a cabochon using silicon grinding wheels. One of the most popular cabbing machines on the market is the CabKing

There are two different ways you can use the Cabbing Rough that you buy.  Firstly you can try to cut as many cabochons from one piece of gemstone rough as you can so make the most of the cabochons from your piece of rough.  Alternatively there is the selective Cabochon option where you select the best pattern or colors on the slab to create a more beautiful cabochon. This is usually the approach most hobbyist lapidary take as you will usually end up with a more beautifully piece for your efforts as nowadays you can buy some lovely rough for making cabochons inexpensively from eBay or a rock shop.

Cutting a cabochon from a rough rock can take anything between 1 - 3 hours to cut depending on the size of the original Lapidary Rough and the hardness of the gemstone you are cutting. A Lapidary Slab Saw can  take anything up to 30 minutes to make slice through the rough rock so it is best to try to buy a lapidary trim saw with an auto-feed system, so while you're slicing your rock you can be working on something else. Harder rocks will of course take longer to cut through.  For shaping and polishing the cabochon on a the cabbing machine this can take anything from 30 minutes to 2 hours cabochon depending on the hardness of the stone and your skill level as a lapidary.
