Topaz VS Diamonds

White Topaz

It comes from a variety of colorless Topaz. The chemical formula of Topaz is Al₂SiO₄(F, OH)₂ and it is a silicate mineral of Fluorine and Aluminium. Even though Topaz comes in various colors (green, blue, brown, yellow, orange, red, etc.), it is actually transparent in its purest form.

Diamond

With a cubic crystal system, Diamond is a form of carbon that is extremely solid. The carbon atoms that make up a Diamond form a strong covalent bond. Diamond has an attractive transparent appearance and shine that makes it quite unique and captivating.

Properties

Sparkle: Sparkle is one of the most important features of the Diamond where it takes a considerable lead over White Topaz. Diamond is known for maintaining its sparkle forever. White Topaz is good as compared to others but it will lose its sparkle with the passage of time. The reason why White Topaz loses its sparkle is due to the accumulation of scratches.

Durability:

White Topaz is quite a resilient gem with a hardness of impressive 8 on the Mohs scale. On the other hand, a Diamond is known for its toughness and Mohs scale suggests that as well with a hardness level of 10 (almost six times harder as compared to White Topaz). It goes without saying that White Topaz is still harder than most gems out there and would make a great substitute for Diamond. However, it is not as good as a Diamond when it comes to durability.

Diamond goes through

Clarity:

Just like Diamonds, White Topaz is also quite known for their clarity. When in clear form, White Topaz is quite transparent looking. Just like a Diamond, the color of White Topaz is affected by impurities. However, White Topaz is natural and that is why it is deemed as a suitable Diamond substitute.

Diamond is the hardest material and brightest of all gemstones
