How Many Facets Does a Diamond Have? July 26, 2017 – Posted in: Jewelry Blog

When most people think of diamonds, chances are they all picture the same one. But did you know there are more than a few diamond types? Today, we’re going to present you with a crash course on the facets of the most popular diamond types. 

We sort diamonds according to their chemical or physical features. Knowing diamond types in detail probably won’t make a lot of difference to an ordinary shopper. However, if you want to dig deeper and fully understand the ins and outs of diamonds, you’ve come to the right place. 

How Many Facets Does a Diamond Have? 

The gold standard for facets is 58. So round brilliants, cushion, heart, emerald, and oval diamonds all have 58 facets. However, some shapes have less than that.

One of the most significant features of a diamond is its cut. And, the number of diamond facets will depend on their shape and cut.

The cushion-cut diamond was quite common before the use of modern technology. During that period, diamond cutters couldn’t cut circular diamonds, so they went for square or rectangle shapes. So if you’re a fan of vintage jewelry, a cushion-cut diamond ring is the way to go.

However, you are most likely to find them at a lower range. The most common princess-cut diamonds have between 50 and 58 facets. What makes it special is that this cut does a stunning job at hiding inclusions. 

Tip: If you decide to go for the princess cut shape, choose the nearly colorless ones.

Types of Diamonds – Technically Speaking

If you want to dig deeper, here’s a quick overview of the technical diamond classifications. There are two main diamond categories: type I and type II. Type I diamonds have traces of nitrogen, while type II don’t. 

In addition, there are a few sub-categories within these two types: 

  • Type 1a: the most common diamond type. It makes up to 95% of all natural diamonds in the world. Some processes during the formation period show why this diamond type is the most common. As nitrogen is the most abundant element in the atmosphere, it’s easy for it to find its way into the diamond’s structure. These diamonds often vary in color but are usually yellowish due to the nitrogen influence. We can further divide these diamonds into IaA and IaB sub-categories. This classification is due to different nitrogen atoms that affect the diamond color. 
  • Type 1b: These diamonds are very rare. They make up for less than 0.1% of natural diamonds. The nitrogen atoms come in pairs, and they don’t affect the color as much. 
  • Type 1aB: In this sub-category, nitrogen atoms accumulate next to each other. This process gives these diamonds a yellow or brown shade. 
  • Type 2a: Diamonds that belong to this category have almost no traces of other elements (nitrogen or boron). These are the chemically purest diamonds out there. It’s why there’s a high demand for them. They are mostly colorless but can also come in yellow, red, or blue. 
  • Type 2b: These diamonds make up for less than 0.1% of natural diamonds in the world. Therefore, this sets them in competition with 1b type for the rarest diamonds in the world. Type 2b diamonds contain traces of boron instead of nitrogen. That’s why they’re usually blue or gray in hue. 

Diamond Types for Most Shoppers

You can see how understanding diamond types from the gemological perspective can require a bit of technical knowledge. However, most jewelers and shoppers won’t classify them that way. The next time you shop for diamonds, you can ask for some of these types: 

1. Natural Diamonds 

This is probably the most common diamond type that everyone pictures in their head. White natural diamonds are the most common diamond type available across jewelry shops everywhere. Diamond miners mine natural diamonds from the ground and sell them without modifying their properties. 

2. Treated Diamonds 

These are diamonds that have the same origin as natural diamonds. However, due to lack of color or clarity, they undergo an additional enhancement to give them a better look. Some of the most common treatments include hiding the inclusions on the diamond. Modifying their appearance is the only way to sell these diamonds. And it goes without saying that their price is much lower than the natural diamonds. 

3. Lab-Grown Diamonds 

Lab-grown (or man-made) diamonds are becoming more and more popular each year. These are commercial use diamonds that come from laboratories. And as the technology for manufacturing these diamonds improves, their price keeps going down. At first, the man-made diamond’s price was 30% of the price of a regular diamond. Today, you’ll find artificial diamonds that are 50% cheaper. Predictions are that in a few years, they will be 70% cheaper than natural diamonds. 

Just to give you an example, imagine two diamonds of the same physical properties. You can buy one for $6,000, and the other for $2,000. This explains why there has been a massive increase in demand for man-made diamonds over the years. 

Warning: There are a lot of risks to Lab-Grown Diamonds. Read our Lab Diamond Article before making your purchase.

4. Naturally Colored Diamonds 

Some of the rarest diamonds you can find in the world are naturally colored diamonds. And they certainly are the most stunning type. They come in all colors you can imagine, the most popular being pink, blue, red, and orange. These diamonds have become more and more popular because of a recent trend set by celebrities. They like to show their engagement rings made of natural-colored diamonds on social networks, making others want them too. 

Also, note that there are two subsets of these diamonds – natural-colored, treated-colored, and man-made-colored diamonds. That means you can buy a man-made diamond at a more affordable price.
