What Makes Blue Topaz Different from Other Topaz Varieties?

Blue topaz is different from other topaz varieties in several ways. Here are some of the main differences:

• Color: Blue topaz is the most popular color of topaz, but it is not natural. Most blue topaz is clear topaz that has been irradiated and heat-treated to produce the blue hue. Natural blue topaz is very rare and usually has a pale blue color. Other topaz colors include white, yellow, orange, pink, brown, and green. Some of these colors are also enhanced by treatments, while others are natural.
• Price: Blue topaz is one of the most affordable gemstones, especially the lighter shades of blue. The darker and more intense the blue, the higher the price. Natural blue topaz is more expensive than treated blue topaz, but still cheaper than other topaz colors. White topaz is also very inexpensive, while yellow, orange, pink, and green topaz are more costly. The most valuable topaz color is the rare imperial topaz, which has a reddish-orange hue.
• Availability: Blue topaz is widely available in various shapes and sizes, thanks to the abundance of clear topaz and the ease of treatment. Natural blue topaz is scarce and hard to find. Other topaz colors have varying degrees of availability, depending on the source and demand. Imperial topaz is the most rare and sought-after topaz variety.
