Steps on Cutting Gemstones with Dremel

There is a step-by-step process you have to follow when you want to cut gems using a Dremel.

Step 1: Tool Needs to Be Prepared

The very first thing you will need to do is insert the bits of diamond into the Dremel. These bits will have to be inserted into the very last hole of the tool you are using. Once you slide it back, all you have to do is use screws to shut it tight.

In case, if you’re using an electrical one, make sure you have it turned off before inserting the bits inside.

Step 2: The Gems Have to Be Formed

The gems are formed, but you have to shape it up in a way so that it can be cut. Otherwise, you will have problems working with it. Your main task in this step of the process is to remove all the inclusions in the gemstone. This will give you a much better surface to work on.

With a diamond cutting lap of 20 grit, you have to make a basic shape of the gem. Try to keep water in hand and put some on the lap so that the gem can cool down after being shaped.

Now, if you want the process to go smoother, then you will have to use wax and dop stick. They have to be bonded completely before you start with the lap. This step is not compulsory, do this only if you want to. But it might work in your favor as working with the gemstone will be much easier and more comfortable.

Step 3: The Gemstones Need to Be Cut

At this point, you are done shaping the gem. To shape them to your liking, you will have to take the Dremel out. The first thing you do is turn the tool on if you are using an electrical and automatic one.

Then you have to clamp the gemstone into place to make sure it does not move when you are working on it with the Dremel. Any movement could very easily destroy the whole gemstone.

Now comes the speed setting of the tool, this has to be set to a moderate speed.This is important as a high speed could possibly damage both the gem as well as the motor of the Dremel.

To get a flat table surface, you have to make straight 45° angle cuts at a low speed with the Dremel. Sometimes with tougher stones, you will have to make several passes before you can cut bits of it off.

When you want to make the main crown facets, you will have to change up the angle you are cutting at. There are times when each of the facets will not meet, but that is not a problem as this can easily be dealt with in the next stage of the process.

After you are done cutting the gemstones with the Dremel, you have to remember to take out the diamond bits you put inside at an earlier stage of this process.

Step 4: The Gemstones Need to Be Polished

You are done cutting the gemstone, now you must move on to the very last step, and after that, you will be done. This is when the Dremel is going to be used for the polishing. But now you have to attach the lowest grit. Your job now is to grind till all the rough edges are gone, and you are left with a plain surface.

The tip has to lay flat with the gem so that it can work most efficiently and gets the best result.

When the grinding is done, all you have left to do is polish the gem. Use a cloth for this task as it will give you a good outcome. Use an oxidized solution, and you will be left with some very sparkly gems when you are done. That is all you have to do in order to use a Dremel and cut gemstones to perfection!
