Usable Gems... and a little opinion.


Iolite Is The Look-Alike Gem



Iolite is a beautiful gem... that look like sapphire or tanzanite, according to many.

Iolite, have you heard of it? The name is pronounced eye-o-lite, or as our madagascar-gems-com partner in Madagascar would say it... e-yo-leete.

Iolite is the gem variety of a mineral named cordetite. All of these "ite" names, while pleasing to the scientific community, can be really tedious. I much prefer the more romantic gem names, such as emerald, sapphire, and topaz.

But I digress, so back to the subject...

Iolite is the official name, so we will use it here. The name comes from the Greek word "ios" which supposedly means "violet."

This beautiful gem is also known as water sapphire. Not a bad name, but neither is it unique, since it borrows the sapphire name.

Blue-violet is the color of this gem. As I mentioned earlier, sapphire and tanzanite also occur in this same color. One of the favorable characteristics of iolite is that it is more affordable.

Iolite has other interesting characteristics as well. The Vikings used it as a polarizing filter to see through the haze at sea.


Iolite is a relatively hard gem, so it is very suitable for use in jewelry to be worn often.

Chemically, it is a magnesium-alumino silicate, with (usually) some ferrous iron (Fe2+) and ferric iron (Fe3+) present. This gets us dangerously close to a discussion of the oxidation state of elements and their influence on colors... but we will not go there today.

Iolite is becoming more popular in manufactured jewelry. This is primarily due to the popularity of the much more expensive and similar colored gem, tanzanite.

Iolite continues to be very affordable from gem dealers (especially this one).

Reasons for this continued affordability can be attributed to its presence in commercial mining quantities on several continents.

Iolite is found in Madagascar, Namibia, Tanzania, Brazil, Sri Lanka, Burma, Australia, and Canada.

All-in-all, this is a very desirable gem.

A Google search for the keyword phrase iolite gems returns a number of internet listings and ads with additional information and photos.
