What are SI Diamonds?

An SI diamond's clarity is based on a grade from the diamond clarity scale. SI stands for a diamond that is "slightly included." Slightly included stones are divided into SI1 and SI2 diamonds. An SI1 diamond is a higher clarity grade than SI2 diamonds. SI diamonds can take any diamond shape, color, cut, and carat weight.

SI clarity diamonds have noticeable inclusions to the naked eye. Inclusions are imperfections that have been captured in the diamond crystal as it formed. Any diamonds can have inclusions and blemishes, whether they're natural diamonds or lab grown.

Inclusions may be bits of other minerals, gas, or air that have been trapped in the crystal. A diamond forms under immense pressure and heat, which is why the inclusions happen.

What are the best diamond shapes for an SI diamond?

There is no best diamond shape for SI diamonds. But some SI diamond shapes show their inclusions more than others.

Emerald cut diamonds, Asscher cut diamonds, and other step-cut diamonds may show inclusions to the naked eye more than other diamond cuts. Even if they're of the same diamond quality, two diamonds may have inclusions that make them look different.

Are SI diamonds real?

SI diamonds are real diamonds. The slightly included clarity grades are official diamond grades on a grading report. However, not all grading labs grade the same. Our diamonds may come with a GIA certificate, IGI certificate, GCAL certificate, or GSI diamond certificate.

Are Lab Grown SI Diamonds Real?

Lab grown diamonds with SI diamond grades are also real diamonds. Lab grown diamonds are often confused with other colorless diamond alternatives like cubic zirconia. Lab grown diamonds have the same general properties as a natural diamond. They follow the same clarity scale too.

That being said, a lab grown diamond with an SI clarity grade is more likely to be free of inclusions to the naked eye than a natural diamond would be. Though all diamonds can have visible inclusions and clarity characteristics, the types of inclusions are limited.

The isolated environment of a lab grown diamond minimizes the number of dark mineral inclusions. A lab diamond with an SI clarity diamond may have small inclusions shaped like skinny needles or white pinpoints. These types of inclusions are harder to see with the naked eye, unless you're looking at the diamond up close.

Are SI1 Diamonds Good Quality?

Buying SI clarity diamonds is up to personal preference. They're less expensive than many other diamond clarity grades. On the flip side, slightly included diamonds have more inclusions than many other clarity grades.

A high quality diamond is not based on clarity grade alone. SI clarity grades only tell us the diamond is slightly included. Diamond clarity grades are related to its light performance and can also impact its diamond structure. Too many internal inclusions and surface blemishes in a diamond.

Besides those two factors, clarity can't tell us if the diamond has a good color grade or cut quality for its carat weight. These are all individual pillars that contribute to the overall quality of a diamond.

It is possible to have a good SI clarity diamond and it's also possible to possess a low-quality SI clarity diamond. Finding the perfect diamond for your diamond engagement ring setting is all about balancing other details.

What's Better, SI Diamonds or VVS Diamonds?

According to the Gemological Institute of America (GIA), VVS diamond clarity is better than SI diamond clarity. Very very slightly included diamonds are two tiers higher than SI diamonds. They have very very small inclusions that are barely noticeable, even under magnification.

A VVS diamond is not the highest clarity grade available. Next comes an internally flawless diamond and the rarest clarity grade of all, flawless diamonds.

An SI diamond isn't considered an eye clean diamond clarity grade. A diamond is considered eye-clean when it has no visible imperfections to the naked eye. SI1 diamonds are less likely to have as many or as obvious inclusions as SI2 diamonds.

In fact, there's only one clarity grade tier below slightly included diamonds: included diamonds, or I clarity diamonds. Clean Origin doesn't carry I clarity grade diamonds.

Though SI1 and si2 diamonds aren't considered eye-clean, that doesn't mean there aren't eye-clean SI1 and si2 diamonds available. They're just harder to find ones with fewer inclusions.

While a VVS diamond clarity grade may technically be "better" by clarity standards, it might not be better for your wallet if you're on a tight budget. Sometimes a less expensive SI clarity diamond ca be better than a VVS diamond. However, a larger diamond with a higher carat weight may require higher grades than SI clarity.

But if you're looking for a stone for your one-carat diamond ring, an SI clarity could be a good diamond for you, provided the other qualities are good as well.

What Are SI Diamonds Worth?

The resale value of diamonds as a whole isn't worth investing in. Only the rarest and most valuable stones within the diamond industry have high dollar values. Fancy colored diamonds are also worth quite a lot, more if they receive no treatment.

As a provider of ethical lab grown diamonds, the overall monetary worth of our SI diamonds is not a lot. It would be the same standard as other resale shops, pawnshops, or marketplaces.

Are SI Diamonds Worth Buying?

Yes, an SI diamond is well worth buying if you like it. An SI clarity diamond is only worth what it means to you. When people buy SI clarity diamonds, they're not usually thinking about the monetary worth, but rather the person they're going to give it to. It's not about how much it costs or how large the carat weight is.

The SI diamond you pick today is the one that will represent your eternal commitment and love captured in an engagement ring setting made of luxurious recycled metals. Every diamond, whether it's an SI clarity diamond or not, is worth so much more in an engagement ring presented with love.

Do SI Diamonds Pass Diamond Testers?

Yes, SI diamonds pass diamond testers because they are real--they're just not one of the higher clarity grades.
