"Swiss topaz" is a term often used in the gem trade, but it can be misleading. Here's what you need to know:

### 1. Swiss Topaz vs. Blue Topaz

The term Swiss topaz typically refers to Swiss Blue Topaz, a vivid, bright blue variety of treated topaz. It is not naturally that color—instead:

Most blue topaz, including Swiss Blue, starts as *colorless or pale blue topaz**.

It is then treated using *irradiation** followed by heat treatment to produce its vibrant blue color.

There are three main commercial types of blue topaz:

* Sky Blue – pale blue

* Swiss Blue – bright, vivid blue

* London Blue – deep, inky blue

### 2. Origin Misconception

"Swiss" in the name does not indicate origin. The topaz is not necessarily from Switzerland. Most topaz comes from countries like Brazil, Nigeria, Sri Lanka, and Pakistan.

### 3. Is It Real Topaz?

Yes—**Swiss Blue Topaz is genuine topaz**, just enhanced to improve its color. It's a popular and affordable alternative to natural blue gemstones like aquamarine or sapphire.
