What are SI2 diamonds?

We need to know what makes SI2 diamonds different from other clarity grades in order to understand them. A slightly included SI2 diamond is a common clarity diamond. This grade indicates whether the diamond has inclusions or blemishes that affect its appearance.

Cost-wise, SI2 diamonds are usually less expensive than diamonds with higher clarity grades, such as SI1 or VS2. From $2,400 to $3,500 for a 1 carat diamond, SI2 diamonds can be bought. It’s important to remember, though, that the quality of SI2 diamonds depends on how well you can see the inclusions. Before buying a SI2 diamond, it’s important to check to see if the inclusions can be seen.

SI2 Clarity Grade

Between value and noticeable inclusions, SI2 diamonds are a good option. As diamond experts, we can tell you that the SI2 clarity grade is a big deal when buying a diamond. Some important things to know about SI2 diamonds are:

  • Under a magnification of 10X, SI2 diamonds have visible inclusions. These flaws could make the diamond less clear overall.
  • Between 70% and 95% of SI2 diamonds aren’t eye-clean, which means that you can see the flaws in them.
  • With a more affordable diamond and acceptable clarity, these diamonds provide the best value for money.
  • On the diamond clarity scale, SI2 is at the lower end. You can see inclusions when you enlarge a picture, but you can’t see them with the naked eye.

Note that the quality of SI2 diamonds is based on how easily the inclusions can be seen. It’s important to know if the inclusions can be seen in a SI2 diamond before buying it. This will help you figure out if the diamond fits you well.

Types of Inclusions

Let’s learn about SI2 diamond flaws. These include the following:

  1. Small crystals: Tiny mineral deposits get stuck inside diamonds as they form deep in the earth. Crystal inclusions can be tiny, clear, or almost clear specks. A jeweler’s loupe or microscope can reveal them. A less noticeable inclusion in SI2 diamonds is small crystals.
  2. Pinpoints: Pinpoints are tiny inclusions that look like pinheads. Small mineral crystals or other minerals are often mixed in. Light points can appear alone or in groups. These are too small to see without a magnifying glass.
  3. Feathers: Diamond feathers are cracks. Feathers may stand out more than small crystals and pinpoints, especially if they’re larger or closer to the diamond.
  4. Clouds: Tiny inclusions that look like pinpoints make a diamond cloudy. These tiny imperfections may affect the stone’s clarity and are hard to see. Without magnification, clouds are hard to distinguish.
  5. Large dark inclusions: Large dark inclusions are more noticeable than white ones.

Remember that SI2 diamonds have these flaws, but how they affect a diamond’s beauty and value depends on its size, location, and light interaction.

How to Buy SI2 Diamonds

There are some important things to remember when you buy SI2 diamonds.

Look for Eye-Clean Diamonds

When choosing a SI2 diamond, it’s important to make sure it’s clean for your own eyes. You can tell if there are inclusions with the naked eye by looking closely at the diamond and using high-tech images.

Look at the clarity plot.

We should carefully look over the clarity plot on the GIA certificate to make sure the SI2 diamond is good. The clarity plot is a graph that shows where the flaws in the diamond are and how big they are. We can learn more about the diamond’s clarity rating and see if it meets our standards for an eye-clean diamond by looking at the clarity plot.

The clarity plot on the GIA certificate is very important for figuring out the clarity grade of an SI2 diamond. Finding the location and type of inclusions in the diamond is possible with this plot.

Look for a SI2 diamond with inclusions that are dispersed rather than concentrated in a single location. The edges of the diamond should have inclusions because they cover the inclusions better and make them less noticeable. 

Seek expert’s advice.

A skilled grader’s opinion on the diamond’s clarity is also something we want to find. This will help us figure out if the inclusions can be seen without a microscope or only with a 10X lens.

Let’s move on to the next part, which talks about trying to find inclusions on the edges.

Try to get inclusions on the edges.

If we want to buy SI2 diamonds, we should definitely look for inclusions on the edges so that they are better covered and seen. This is because flaws near the edges are less likely to change the way the diamond looks overall, and they are easy to hide with prongs or settings.

Paying attention to inclusions on the edges can be helpful for the following reasons:

  • Appearance pretty: Inclusions on the edges are less noticeable, which can help make the diamond look better.
  • Better value: SI2 diamonds with flaws on the edges tend to be less expensive than those with flaws in the middle.
  • Hit a balance between size and clarity: You might be able to find bigger SI2 diamonds that still look clean if you focus on inclusions on the edges.
  • Help from experts: To find the best SI2 diamonds with inclusions on the edges, use a diamond grading certificate and think about using a diamond concierge service.

Look for spread-out inclusions.

Remember that SI2 diamonds do not all possess equal characteristics. Seek out SI2 diamonds with well-distributed inclusions for improved clarity and added value. You can ensure a more eye-catching, clean appearance by selecting ones with spread-out inclusions. It is very important to keep this in mind when looking at diamond prices, since flawless diamonds cost more.

Consider your Budget

SI2 diamonds may have more noticeable inclusions than higher clarity grades, but they are less expensive, so you can spend more on other things that are more important, like the quality of the cut. Finding an eye-clean diamond that suits your budget and personal preference is the most important factor in determining whether SI2 diamond clarity is good.

Pick the shape you like.

When we buy SI2 diamonds, we should carefully think about what diamond shape we want and look at a number of different options. Here are some ideas to help you decide what to do:

  • Brilliant diamonds: Round brilliant diamonds are a good choice because they hide flaws better than other shapes.
  • Step-cut diamond: If you want a step-cut diamond, like an emerald or Asscher cut, keep in mind that these shapes have more faces, which can make flaws more noticeable.
  • Carat size: Larger diamonds may have more noticeable inclusions, so choose a slightly smaller carat size to reduce visibility.
  • Twinning wisps: Look for SI2 diamonds that have twinning wisps. These are thin, thread-like inclusions that can make the diamond look more beautiful.

Pick out a GIA ID card.

When we choose an SI2 diamond, the first thing we do is look at its GIA certificate to make sure it is real. There is important information about the diamond’s qualities on the GIA certificate, such as its clarity grade, color grade, and carat weight.

Where to Buy SI2 Diamonds

As diamond experts, we know that deciding on SI2 diamond clarity can be a personal choice based on personal preference and financial limitations. Finding a cheap SI2 diamond can be important for buyers who want to get a good stone without spending a lot of money. Here are some of the places you can buy SI2 diamonds and a few important things to remember:

  • Prices at online stores like Blue Nile are lower than in-person stores. This means that you can spend more of your money on other things, like the cut quality, color, and carat weight.
  • Both James Allen and Blue Nile have high-quality pictures and virtual inspection tools that make it easier to check the diamond’s clarity from home.
  • There are more SI2 diamonds in larger sizes and shapes to choose from when you shop online.
  • To ensure the accuracy and reliability of the laboratory report, it is important to look for independent grading labs like GIA.


To conclude, understanding SI2 diamonds helps you buy a diamond wisely and affordably. Microinclusions are visible under 10X magnification, balancing SI2 diamonds’ value and flaws. SI2 diamonds aren’t always eye-clean, but some are. This makes them a good choice for saving money without sacrificing clarity.

To make sure an SI2 diamond has no obvious flaws and looks clean to the naked eye, inspect it before buying. High-tech photos and the GIA certificate’s clarity plot can help. In addition to the diamond’s shape, its inclusions and distribution can affect its appearance and value.

If you are looking for an eye-clean SI2 sparkly diamond that fits your style preference, James Allen offers a large inventory of loose diamonds.

The choice of SI2 diamond clarity depends on personal tastes and budget. With the right information and help, you can find an SI2 diamond that meets your needs and is beautiful and affordable for your next big purchase.
