These two stones at first look appear to be the same. But if we take a moment with each, they can be easily distinguished from one another. The important thing as we begin to differentiate crystals with similar physical characteristics is to compare two stones with the same finish.
Take a look at a tumbled sodalite and a tumbled lapis lazuli. Compare a rough sodalite with a rough lapis lazuli. After you've come to be able to tell these apart when compared to the other of the same finish, then see if you can tell them apart when comparing different finishes. Also, once you see the differences you can know what you're looking at without a comparison.
First things first, let's see what these look like.
Both are blue, with white markings or veins. The mineral structure is very similar which is why they appear alike and are often mistaken. In fact, as I perused the internet I saw sodalite advertised as lapis lazuli and lapis lazuli advertised as sodalite. That's how similar they are, even suppliers sell them incorrectly.
As described in the Book of Stones (see below for reference) both of these are a sodium aluminum silicate with an isometric crystalline structure. The white color you see in each photo is white calcite which occurs naturally in both lapis lazuli and sodalite.
So, what's the trick to telling them apart? There are two distinct features to look for.
1. Pyrite. Lapis Lazuli has pyrite inclusions - pyrite is fool's gold. It has a metallic gold like appearance. Some Lapis Lazuli, like the point in the photo above (right), has a lot of pyrite and is easily seen. Others, like the raw stone above (first set of pics, right), have less or the pyrite is less easily seen. To me tumbled and polished stones are easiest to discern.
2. The blue color. Sodalite is often a darker blue, sometimes gray or such a dark blue that it appears nearly black in some places on a stone. Lapis Lazuli typically has a brighter blue color.
So, is your Lapis actually Lapis? Is your sodalite actually sodalite? If you've got both, take a look at the differences, you may be able to help a friend tell them apart one day.

Thanks for this article. Yes, they are sometimes sold as each other, perhaps an honest mistake in some cases. So on the Internet, only buy stones based on the actual picture of the stone(s) you are buying; or else you may get dark blue Sodalite rather than royal blue Lapis Lazuli, or vice versa.
