Diamonds and crystals are both beautiful and sparkling, but they are not the same thing. Diamonds are a specific type of crystal, but crystals can also be made from a variety of other materials. Understanding the differences between these two types of gems can help you make informed decisions when buying or appreciating them.

Diamonds Vs. Crystals – Key differences


The main difference between diamonds and crystals is in their composition. Diamonds are made of carbon atoms that are tightly packed together in a crystal structure, while crystals can be made from a wide variety of materials, including quartz, salt, and even ice. Diamonds are formed under high pressure and high temperature deep in the earth’s crust, whereas Crystals can be formed through natural process or by artificial means.


Another difference between diamonds and crystals is in their hardness. Diamonds are much harder than most other crystals. They have a Mohs hardness of 10, which is the highest rating on the scale, while most other crystals have a hardness of 7 or lower. This means that diamonds are much more durable and resistant to scratching and chipping than other crystals. This makes diamonds ideal for use in jewelry and other applications that require durability.


Another difference between diamonds and crystals is in their transparency. Diamonds are highly transparent and can be cut and polished to produce a brilliant sparkle, while many crystals are not as transparent and may have a cloudy or opaque appearance. This makes diamonds more appealing for use in jewelry and other decorative applications.


In terms of value, diamonds are generally considered to be more valuable than other crystals. They are often used in jewelry and can be quite expensive, while many other crystals are used for decorative or healing purposes and are not as valuable. This is due to the rarity and uniqueness of diamonds, making it a valuable possession.

How can you tell difference between diamond and crystal?

Diamonds and crystals can be difficult to tell apart, but there are a few key differences between the two.

  1. Hardness: Diamond is the hardest naturally occurring mineral, measuring 10 on the Mohs scale of mineral hardness. Crystals, on the other hand, can vary in hardness depending on the type of crystal, but most are less hard than diamonds.
  2. Sparkle: Diamonds are known for their exceptional sparkle, due to their high refractive index and ability to disperse light. Crystals, while they can be glossy, do not have the same level of sparkle as diamonds.
  3. Clarity: Diamonds are typically more transparent and have fewer inclusions than crystals. Crystals often have internal flaws, which can make them appear cloudy or hazy.
  4. Color: Diamonds are typically colorless, but can come in a variety of other colors. Crystals come in a wide range of colors as well, but the colors are often more vibrant and less consistent than in diamonds.
  5. Price: Diamonds are much more expensive than crystals, due to their rarity and value.

Lastly, Diamonds can be identified by a professional gemologist using a loupe or microscope and also by doing a “Diamond Tester” test which is a device that will indicate if the stone is a diamond or not.

How to care for diamonds and crystals

Diamonds and crystals are both beautiful and unique, but they require different care. Here are some tips on how to care for each:


  • Store diamonds separately from other jewelry to avoid scratches.
  • Clean diamonds with a mild detergent and warm water. Avoid chemicals, steam cleaners, and ultrasonic cleaners.
  • Dry diamonds with a soft cloth.
  • Inspect your diamond jewelry regularly for loose stones or damage.


  • Avoid using harsh chemicals or cleaners on crystals. Stick to mild soap and water.
  • Don’t expose crystals to extreme heat or cold.
  • Keep crystals away from direct sunlight.
  • Store crystals in a soft, padded bag or box.

Which is more valuable diamond or crystal?

While diamonds and crystals both have value, diamonds are generally more valuable. Diamonds are rarer than crystals, and they are also much harder, meaning they can withstand a lot of wear and tear. Additionally, diamonds can be used for a variety of purposes, such as jewelry, while crystals are mainly used for decoration.

What is better than a diamond?

While diamonds are undoubtedly beautiful, there are many other precious stones and minerals that are equally as gorgeous. Crystals, for example, come in a wide variety of colors and shapes, and can be used in a variety of ways.

In terms of hardness, diamonds are the hardest known natural material on Earth. However, crystals can be just as strong – depending on the type of crystal. For example, quartz is one of the toughest minerals out there.

When it comes to light refraction, diamonds rank high with a 2.42 dispersion rating. But again, there are other minerals that can rival diamonds in this department. Opals, for instance, have a higher dispersion rating than diamonds.

So, while diamonds may be considered the “queen of gems,” there are plenty of other precious stones and minerals that are just as stunning – if not more so.

Is Swarovski a diamond or crystal?

Swarovski is a brand that produces crystals. These are not diamonds, but rather, a type of glass that is cut and faceted to mimic diamonds. Swarovski crystals are used in a variety of applications, including jewelry, watches, and other accessories.

What crystal is similar to diamond?

There are a few crystals that have similar properties to diamonds. Cubic zirconia is one of the most popular diamond simulants. It is less expensive than diamonds and has a Mohs hardness of 8.5, which is just slightly lower than diamonds. Another common simulant is moissanite. This crystal has a refractive index that is higher than diamonds, meaning that it sparkles even more than diamonds! However, moissanite is also softer than diamonds, with a Mohs hardness of 9.25.

How are crystals formed?

Crystals are formed when atoms bond together in a repeating, three-dimensional pattern. The word crystal comes from the Greek word for ice, because early people thought crystals were frozen water. The most common type of crystal is quartz.

Which is expensive than diamond?

There are a few things that are more expensive than diamonds, including:

  • Rubies
  • Sapphires
  • Emeralds
  • Gold

This is due to a number of factors, including the rarity of the stone, the demand for the stone, and the difficulty in mining and cutting the stone.

What is the cheapest diamond?

The cheapest diamond is a type of carbon crystal that is found in nature. Diamonds are the hardest known natural material and have a high refractive index, making them valuable for both jewelry and industrial applications.

Which crystal is best for health?

There are many different types of crystals, each with their own unique properties. While some crystals are better suited for certain purposes than others, there is no one “best” crystal for health. However, some popular choices for crystal healing include amethyst, quartz, and tourmaline. These crystals can help to promote relaxation, stress relief, and overall well-being.
