The first time I saw petrified dinosaur bone was nearly 19 years ago. It was a red agatized dinosaur bone also known as gembone. Gembone is made when agate fills in all the nooks and crannies of the bone leaving you with a very interesting pattern.
Here is a great picture of the patterning in gembone.
One of my favorite things to do with gembone is to inlay it into a ring. It makes a great ring for both men and women. It so happens that I was making one for a client and had the camera running.
I thought I would walk you through the some of the basics.
Step #1 I start with a sterling silver or a gold cast ring. The ring has a cavity in it for the gembone to be set into. This cavity could be any shape. For this example I am using a rectangle shape.
Step #2 The second thing I do is select my rough dinosaur gembone and cut a piece with a trim saw. This particular piece was a sweet find.
Have you ever wanted to make a shadow band that fits right next to your diamond or gemstone ring? Well, here is a short video on how to use wax and a few tools to create a model ring that can be cast in gold or silver.
I will be using a green wax which melts at around 230 degrees and is one of the harder wax materials for model making. The modeling wax is made by a company called Matt. They make a number of waxes ranging in melting temperature and malleability.
There are three main types of modeling wax that I use to make a model.
The blue wax is soft and melts at a low temperature. (200 degrees)
Thepurple wax is slightly harder and with a slightly higher melting temperature then the blue. (225 degrees)
The green wax is the hardest of the three and melts at around 230 degrees.
I prefer the green for any work that needs exact detail and a shadow band needs to be exactly the same contour as the ring it is shadowing.

Annealing is the term for softening metal so that it is malleable. The process involves heating the metal and then cooling it. Cooling the metal can be achieved through air cooling, quenching and sometimes both.
Sterling silver is heated to a dull red(900F). Let it lose its redness and then quench in cool water. (Presto you have soft metal). There are a few steps before you can heat the baby up.
The metal should be coated in a protective substance called a “Barrier Flux”. It is made up of boric acid and 91% isopropyl alcohol.
Many people use denatured alcohol. I discovered it’s toxic and the human body does not metabolize denatured alcohol. This means it doesn’t leave your body very easily once you have absorbed it. Kind of scary. That is why I recommend 91% isopropyl alcohol because it’s less dangerous.
The 91% isopropyl alcohol burns off nearly as well as denatured alcohol. I do not recommend the 70% isopropyl alcohol.
You can mix the boric and isopropyl solution 50/50 for a thicker solution. This will provide a nice thick coating for your metal. This is good for annealing. If you are soldering you can use 25% boric and 75% isopropyl alcohol.
Use a glass jar with a lid. I use an old pickle jar or you could use
I spent the last week up north in Grand Marais, Minnesota teaching two stone cutting classes back to back at the North House Folk School. What a great couple of groups! I have offered this class a few times and it continues to develop and get better and better. The classes both cut jaspers, agates and petrified dinosaur bone. Here are a few photos of the cabochons they made. I can’t wait to do it again!
This is the most important part of your jewelry wax carving. I will say it again. This is the most important part of your carving. Do not miss these steps!
The most important part of the wax carving process is making sure every thing is square. By square I mean all of our angles are at 90 degree angles. Yup, everything! It doesn’t matter if your design only has curves in it or if you are carving a miniature 2 x 4 piece of lumber. Everything on our wax must be square to start. I will also say this is the most boring of all the steps but necessary.
When picking a piece of wax to carve it should be big enough to hold your design. Make sure if you were to cut out your design that it would fit on the block of wax. If you are lucky enough to
