Topaz jewelry - White Topaz vs Diamond | Which One Is Better?


White topaz is a colorless variety of topaz, a silicate mineral. Topaz comes in other colors, including green, blue, brown, yellow, and orange.

Topaz forms when water from nearby rocks crystallizes magma into a rock known as pegmatite. This rock hides in inactive volcanoes. Topaz exists inside this rock and becomes colorless once the sunlight hits its surface. Jewelry lovers often use white topaz as a diamond alternative.

What are diamonds?



Diamonds are the most valuable gemstones out there. They are rare minerals composed of pure carbon. The arrangement of carbon atoms in the lattice offers the diamond its exceptional properties.

Diamonds form when carbon deposits in the depths of the earth’s crust are subject to pressure and high temperature. Some diamonds take shape in a few days or months, and others materialize after millions of years.

What’s the difference between diamonds and white topaz?

Let’s discuss the factors that differentiate diamonds from white topaz.


Color is the main characteristic that makes white topaz and diamond similar. Both gemstones are colorless in their purest form.

In diamonds, D-F grades are the most expensive ones. As the grades get lower, the price and quality of the diamond also decrease. 

On the other hand, white topaz is transparent or translucent. It may contain inclusions or minor impurities that may affect its color quality. A low-quality stone may appear milky and cloudy.

An inexperienced eye can easily confuse a perfectly colorless white topaz with a diamond.


The cost of white topaz is way less than a diamond. Diamond’s rarity and high popularity contribute to its high price. 

White topaz can be a fantastic alternative to the diamond if you have budget constraints. 


Diamonds are considered one of the most precious and prestigious gemstones worldwide. They are typically passed down as heirlooms from generation to generation. 

On the other hand, white topaz doesn’t belong to the precious gemstone category. Good quality white topaz gemstones are easily accessible, making them less valuable. 


Diamond is the most durable gemstone. It’s famous for its flawless ranking of 10 on the Mohs hardness scale. Diamonds are scratch-resistant and almost indestructible.

Topaz comes close at 8 on the Mohs scale, making it the hardest natural silicate mineral in the world. Topaz is harder than most of the gemstones out there. However, it can crack, chip, or even break with a strong enough hit. Moreover, scratches can build up and make a white topaz lose its luster.


Diamonds don’t require a lot of maintenance. They can stay shiny for a long time without consistent care. However, the gemstone may appear cloudy with dirt or oil on its surface. 

The best way to clean diamond jewelry is by using a soft-bristled brush and warm soapy water. 

On the other hand, white topaz is more prone to scratches which may make the gemstone unattractive over time. Consider getting it re-polished by a professional jeweler to bring back its luster. 

You can use an ultrasonic cleaner for diamond jewelry but not white topaz, as it may get damaged. 

Strong chemicals in house cleaning products can damage diamond and white topaz stones over time. So, we advise you to avoid wearing diamond or white topaz jewelry while doing chores like cleaning, laundry, and washing dishes. 

💡 Take Note: It’s essential to get white topaz and diamond professionally checked frequently to ensure they are in their best shape.

White topaz and diamond appear similar; however, trained eyes can tell the difference. Diamond is more prestigious, more durable, and maintenance. However, when it comes to price, white topaz is more affordable.
