What's more? Rubies are typically found in Myanmar and Afghanistan, amongst other places, and are considered to be one of the most valuable and sought-after gemstones.

What is Diamond?

Did you know a diamond is a precious gemstone made of carbon atoms? Also, it has been compressed under extreme pressure and heat deep underground within the Earth's mantle. Diamonds are highly valued for their hardness, brilliance, and luster, and are often used to make jewelry and other decorative items.

Comparison of Ruby and Diamond

Both of these precious stones have been around for centuries and have been treasured and celebrated by many cultures. But what really sets them apart? Let's take a look at the comparison of ruby vs diamond.


Diamonds come in a variety of colors, from dull yellowish color to blue and beyond. Rubies, on the other hand, are primarily found in the exceptional natural color of red hue. While some rubies can have a slight orange or pink hue, they’re generally known for their deep red color.


Both diamonds and rubies can vary in terms of clarity. However, diamonds are often more expensive due to the fact that they’re more transparent, have fewer inclusions and are graded at magnification of 10x. Rubies, on the other hand, have few apparent inclusions, but they can be just as beautiful and worthy as diamonds.


Both stones can be cut into different shapes and sizes. Diamonds are usually cut into the traditional round brilliant cut or princess cut, while rubies can be cut into many different shapes and sizes.

Carat Weight

Diamonds weigh more than rubies. A 1 carat diamond will be bigger than a 1 carat ruby. In addition, diamonds are typically more expensive than rubies since they’re larger and heavier.


Most obvious difference is diamonds are more expensive than rubies, due to their greater rarity and value. However, both incredible gems can be found at a variety of different price points depending on the quality of the stone.

Frequently Asked Questions

I hope I may have cleared all the confusion and you would have made your decision by now. But if you haven't, read on while I answer some of the frequently asked questions. They might help further.

Which is better: diamond or ruby?

It really depends on what fits your style and preferences. Both ruby and diamond are beautiful stones, and it really comes down to personal choice. If you want something unique and fiery, a ruby might be the right choice for you. However, if you want something timeless and classic, a diamond is the way to go!

What is more rare: diamond or ruby?

Both rubies and diamonds are rare gems, but diamonds are generally more rare than rubies. The rarity of each stone can depend on the size, quality, and carat weight, so it is important to evaluate each stone’s individual characteristics in order to make the best decision for you.

Is Ruby as strong as diamond?

I would say that ruby gemstones are not as strong as diamonds. Rubies are a type of corundum, which is an extremely hard mineral, but it is still not as hard as diamonds. In terms of hardness, diamonds rank a 10 on the Mohs scale, while rubies rank a 9. That being said, rubies are still a beautiful and durable gemstone.

What is the Chemical Composition of Rubies vs Diamonds?

Rubies are composed of a mineral called corundum (aluminum oxide). The red color that's so eye-catching in rubies comes from the presence of chromium. This is what sets rubies apart from other stones in the same family, such as pink sapphires. While rubies can naturally occur in different shades of red, the most valuable ones have a rich and intense color.

Pure diamonds have a different chemical composition. Diamonds are made of pure carbon that's been compressed over millions of years. This is why most diamonds are known for their hardness, optimum sparkle and brilliance—they can withstand the toughest of wear and tear. Diamonds also come in a wide range of colors, from red diamond to yellow, pink, blue, and even black. In ruby vs diamond, there is the difference of mineral hardness of only 1 point on the Mohs scale but that makes rubies more than 30% softer than diamonds.
