Blue Zircon vs. Blue Topaz: Key Differences You Must Know

Blue gemstones have long been sought after in astrology and the world of jewelry. The cool color of blue is associated with calmness, clarity, and emotional balance. Of all the blue gemstones, Blue Zircon and Blue Topaz are two of the top contenders, but are often mistaken for one another due to their similar color. While both stones have beautiful shades of blue, they are different in regard to brilliance, origin, durability, price, metaphysical benefits, and their astrological uses. It is important to know the differences because you want to make sure you choose a gemstone that accurately aligns with your purpose. 

In this blo,g we will explore Blue Zircon vs. Blue Topaz in more depth—what sets them apart, how they're similar, and which one is a better fit for you. 

What Is Blue Zircon?

Blue Zircon is a natural gem recognized for its remarkable brilliance and fiery sparkle. Zircon is not to be confused with cubic zirconia, although both have similar spellings. Zircon is a rare and ancient gem (one of the oldest Earth minerals) that formed over billions of years. Zircon has a high refractive index, which means it can shine even more than a diamond. 

Blue Zircon is heated to get its vivid color, meaning brown or dull Zircon crystals turn into beautiful blue, such as sky blue or electric blue, in blue Zircon jewelry. Its fiery brilliance, rarity, and clarity are what made buyers fall in love with blue zircon.

What Is Blue Topaz?

Conversely, Blue Topaz is a fairly plentiful gemstone that occurs in light shades but is usually treated with irradiation and heating to produce deeper blue colors like Swiss Blue, London Blue and Sky Blue. Though common and priced within range, it is appreciated for its appearance, durability and dexterity. 

Blue Topaz has a consistent glass-like luster and is commonly used in contemporary, everyday type jewelry due to the favorable price point and variety in cuts and sizes.
