You’re at some fancy, schmancy dinner party, and your friend’s diamond necklace sparkles in an undeniably beautiful way. You ask her what clarity grade her diamond is, thinking she’ll whisper, “It’s a VVS1,” and she smiles and goes, “It’s an SI1 diamond, can you believe it?”
It turns out that you don’t actually need a perfect diamond to dazzle. In fact, SI1 diamonds are the jewelry world’s best-kept secret, offering stunning sparkle at a more affordable price. Shopping for diamond earrings, a head-turning pendant, or an elegant bracelet? SI1 clarity gives you that fancy look without that fancy price tag.
Let’s delve into why these diamonds are the perfect mix of affordable luxury and how you can wear them with confidence.
The first question we should cover is… what does SI1 even stand for?
On its clarity scale, the GIA (Gemological Institute of America, grading authority on diamonds) classifies SI1 to mean “Slightly Included 1.” In everyday language, this means the diamond is slightly included. In even more everyday language, the diamond has tiny imperfections you can’t see without a microscope.
Is SI1 clarity eye-clean? Definitely. In an engagement ring or other piece of jewelry, your SI1 diamond will appear identical to a diamond with a higher clarity grade unless someone inspects it under magnification.
Ideal for fine jewelry: Necklaces, earrings, and bracelets are typically seen from a few feet away, rendering any microscopic inclusions invisible amidst the glimmer.
Lab-grown perk: When you opt for a lab-grown SI1 diamond, you get the same brilliance as mined with a favorable price point and a clear conscience.
When you’re shopping for diamond jewelry, you want maximum sparkle for minimum spend. That’s where SI1 clarity shines, literally.
Why pay for "flawless" when you can’t even see the difference? With SI1 diamonds, you can go bigger! Put your budget toward carat weight instead of overpaying for higher clarity. If not that, you can upgrade your setting and opt for solid gold or a more intricate design since you’re saving on the stone itself.
Fine jewelry should be worn, not kept away in a jewelry box. SI1 diamonds are durable and look just as stunning years later; no need to stress over microscopic imperfections.
High-end jewelers and stylists often use SI1 diamonds in red carpet pieces because they know that sparkle is sparkle. If it looks good, who cares what the clarity grade is?
Not all SI1 diamonds are created equal. Follow these tips to make sure you’re getting the best bang for your buck:
Best for hiding inclusions: Round, oval, and cushion cuts (great for pendants and earrings).
Use caution with step cuts: Emerald cuts and Asschers can reveal inclusions more easily and more prominently, so make sure they face up eye-clean..
Prong settings let in more light = more sparkle.
Halo designs can disguise any tiny inclusions perfectly, so the center stone appears even more flawless.
Ask them for actual 'real' photos/videos, not only the far-out zoomed certificate images.
Verify via the certificate (GIA or IGI) that the diamond is graded SI1.
Let’s dispel some myths that may be preventing you from finding the perfect SI1 diamond for your engagement ring or jewelry:
The tiny inclusions disappear once mounted in a setting. Your diamond will never reveal them, and neither will you!
Truth: Some of the most sought-after high-end designers use SI1 diamonds in their pieces. When it comes to luxury jewelry, it’s the artistry, the sum of all of its elements together, that makes a piece luxe, not an arbitrary clarity grade.
Truth: Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds, but at a much lower price point and with a more ethical supply chain.
Now for the fun stuff, which is how to style your SI1 diamond jewelry like a boss.
A solitaire SI1 diamond pendant is classic and an everyday essential.
Want drama? Try a cluster pendant, the multiple stones make inclusions even less noticeable.
SI1 diamond studs = instant elegance (and they go with everything).
Drop earrings with SI1 accents add movement and sparkle.
A tennis bracelet with SI1 diamonds looks cohesive; when the stones are in motion, no one’s inspecting the clarity.
Mix your SI1 diamond pieces with other jewelry for a luxe, curated look.

Are SI1 diamonds good quality for necklaces and earrings?
Absolutely! For fine jewelry, such as necklaces, earrings, and bracelets, SI1 diamonds are an excellent choice. Because these kinds of jewelry are usually seen from a small distance, the small inclusions that may exist in SI1 diamonds are undetectable to the naked eye. In other words, you achieve the same brilliance and sparkle as a diamond with higher clarity, but at a much better value.
Will SI1 diamonds appear cloudy or flawed in jewelry?
Nope! An SI1 diamond is likely to be “eye-clean,” which means that inclusions are not visible to the naked eye. In a pendant, earrings, or bracelet, an SI1 diamond will likely look just as flawless as a stone of higher clarity. Just be sure to choose “eye-clean,” well-cut diamond shapes (i.e., round or oval) for maximum brilliance.
How do SI1 diamonds compare to VS or VVS diamonds?
While VS and VVS diamonds contain fewer inclusions, SI1 diamonds have basically the same level of brilliance at a much lower cost. In fine jewelry, where diamonds are viewed from a few inches away (at most), there’s no visible difference. Why pay extra for an upgrade you can’t actually see?
Are lab-grown SI1 diamonds a good choice?
Yes! Lab-grown SI1 diamonds have exactly the same physical and chemical properties as mined diamonds, but at a significantly lower price point. They’re also more sustainable than mined diamonds, so they’re a wise choice for the eco-conscious shopper who doesn’t want to compromise on luxury.
What's the best diamond shape for SI1 clarity?
Stick to brilliant cuts (round, oval, cushion) for SI1 diamonds because they do a better job at masking inclusions. Avoid step cuts (like emerald or asscher), which showcase imperfections more than brilliant cuts. If you're interested in step cuts, make sure the SI1 diamond is genuinely eye-clean.
Can I wear SI1 diamond jewelry every day?
Absolutely! SI1 diamonds are just as strong as diamonds with higher clarity. Whether you're buying diamond studs, a pendant, or a tennis bracelet, the jewels will stand the test of time and hold their brilliance under normal wear.
At the end of the day, SI1 diamonds prove that you don’t need to splurge on flawless clarity to get breathtaking jewelry. Whether it’s diamond earrings, a pendant, or a bracelet, these stones deliver serious sparkle without the sticker shock.
