Only 5 Steps to Cut & Polish the Petrified Wood

Petrified wood is a beautiful and fascinating type of fossil that has captured the attention of people for centuries. With its unique patterns and colors, petrified wood can be used for a wide range of purposes, from creating jewelry to building furniture. However, in order to make the most of this natural material, it’s important to know how to cut and polish petrified wood properly. In this article, we’ll explore the steps you need to take to create polished petrified wood pieces.

What You’ll Need

Before we dive into the process of cutting and polishing petrified wood, let’s take a look at the materials and tools you’ll need:

  • Petrified wood
  • Slab saw or diamond blade
  • Lapidary grinder
  • Sanding pads (ranging from coarse to fine grit)
  • Polishing compound
  • Polishing wheel

Step 1: Choose Your Piece of Petrified Wood

The first step in cutting and polishing petrified wood is to choose your piece. Look for a piece that is free from cracks or other damage and that will fit comfortably on your lapidary grinder. Keep in mind that larger pieces may require more time and effort to work with, so if you’re new to the process, it may be best to start with a smaller piece.

Step 2: Cut the Petrified Wood

Once you’ve selected your piece of petrified wood, it’s time to cut it down to size. This can be done using a slab saw or a diamond blade. A slab saw is a specialized tool that is designed specifically for cutting rocks and minerals. However, if you don’t have access to one, a diamond blade can also work well.

When cutting your petrified wood, be sure to wear safety glasses and gloves to protect yourself from flying debris. Make slow, steady cuts to avoid damaging the piece and to ensure that you get the shape and size you want.

Step 3: Grind and Sand the Petrified Wood

Once your petrified wood is cut to the desired size and shape, it’s time to start grinding and sanding it. This will help to smooth out any rough edges and prepare the surface for polishing.

Start by using a lapidary grinder to remove any large bumps or imperfections on the surface of the petrified wood. Once you’ve done that, switch to a series of sanding pads with progressively finer grits to slowly smooth out the surface. Start with a coarse grit and work your way up to a fine grit, making sure to wipe away any dust and debris between each pass.

Step 4: Polish the Petrified Wood

Now that your petrified wood is sanded and smoothed, it’s time to polish it. To do this, you’ll need a polishing wheel and some polishing compound.

Apply a small amount of polishing compound to the wheel and use it to gently buff the surface of the petrified wood. Make sure to work in small sections and to use a gentle touch to avoid damaging the piece. As you polish, periodically check your progress to make sure you’re achieving the level of shine you want.

Step 5: Finish and Protect Your Petrified Wood

Once you’ve polished your petrified wood to your satisfaction, it’s important to finish and protect it to ensure that it stays looking its best. You can do this by applying a coat of wax or mineral oil to the surface of the piece.

When applying the wax or oil, be sure to use a soft cloth and work in small sections, rubbing the material into the wood until it’s fully absorbed. Let the piece dry completely before handling it again.


Cutting and polishing petrified wood can be a time-consuming process, but the end result is worth the effort. With a little patience and the right tools, you can transform a rough piece of petrified wood into a beautiful and polished work of art. Whether you’re using it to create jewelry, decorate your home, or build furniture, polished petrified wood is sure to impress and amaze anyone who sees it. So why not give it a try and see what you can create?
