The 5 Types of Diamonds You Should 100% Avoid
What types of diamonds should you avoid? What about bad diamond inclusions and good diamond cuts? Education and engagement rings, all in one place.
By Stephanie Dore
Our worst nightmare? You, getting engaged, with a terrible diamond. We just wonât stand for it. We see it all too often these daysâgood, well-meaning folks paying too much, or buying something they donât understand, or settling for something they donât love just because itâs what was in front of them. Well, weâre here to change all that. After all, a lil education never hurt anyone. So while everyoneâs out here telling you to âdo thisâ and âbuy thatâ, we thought weâd take a more frank approach (itâs in our name, darling) and just come right out with the 5 types of diamonds you should avoid, which will hopefully help you land a little softer on the one you should snag!

The âDirt Under Their Fingernailsâ Type of Diamond
Thereâs no denying that some of us just like a partner who isnât afraid to get their hands dirty. So much, in fact, that weâll ignore those little traces of gunk that are just never coming out. Ew. I know. Anyway, moving on. Just know that when it comes to diamonds, that gunk really isnât going anywhere. Weâre talking about eye-visible inclusions here. And honestly, unless youâre going full salt-and-pepper on us (which is a choice), just avoid them. Now, weâre not saying you have to go all the way flawless, or even internally so. Just keep it eye-clean and youâll be a happy camper.
The One With âA Little Extraâ
Curves? Yes please. Weâre all for that. But when it comes to diamonds, having lots of junk in the trunk is really not such a good thing. And it all comes down to cut. To make this more fun, imagine the diamond in your ring is a hamburger. Now, when youâre looking at it from the top, youâre looking down a boring old bun, right? But when you look at it from the side, you can see all the good stuff.
But what happens when you squish the burger (to fit it in your mouth, obvs)? The good stuff inside starts to spread out so you can see it from the top, yeah? Yeah! Well, you donât want it to get too wide, because all the good stuff will fall out (in a diamond, this looks like light leakage (instead of that brilliance coming back to your eye, it goes elsewhere…no fun at all).
You want to find a burger…I mean diamond…thatâs just right. Too much spread and you have a dull diamond, too much weight hidden in the middle and you have a heavy, dull rock thatâs costing you more in carat weight. Just remember, no two 1-carat diamonds are alike. You want to find balance so you donât break the bank on a major bummer. This is one of five types of diamond you definitely want to pass on.

The Edgy One
Okay, okay, weâll admit we kinda have a thing for all of yâall who are a little rough around the edges. Youâve got that mysterious, maybe a little dangerous, vibe, and weâre not complaining. But trust us, that is NOT what you want in a diamond. What weâre talking about here are inclusions around the edges (or at the surface) of your diamond, and how you should probably avoid them.
That means feathers that break the surface, chips, knots, and the like. See, diamonds are haaaaaard. Itâs one of the reasons we love them so. But that also means they are at risk of chipping and breaking if hit in just the right way. I.e. they donât bounce back into shape, like, at all. So, when you have a feather thatâs on the sharp little girdle edge (the outer perimeter of your diamond) or a crystal that breaks the surface (called a knot), that just makes the diamond all the more prone to breakage at that point. Like a windshield with a crack that just keeps spreadingâŠ. Check the clarity plot on your diamond cert or have an expert look at it just to be sure youâre good to go.
The One Thatâs Too Good To Be True
This is a basic rule of life, folks. Common sense that can be readily applied to both your love life and your diamond shopping. If someone is out there trying to sell you a ânaturalâ 3-carat diamond for a 1-carat price⊠run! Fast! Make sure your diamond is certified by a trusted lab, buy it from a reputable source with authentic customer reviews, and if you have a gut, check how itâs feeling.

The One You Donât Love
When it comes to love, they say youâll know when you know, right? Guess what, same with diamonds! While at first they might all seem pretty and sparkly and somewhat interchangeable, once you get to know them, youâll start to really see their unique sides. And thereâs something for everyone. Some of you want flawless, some of you want big (and some small), some of you want fancy colors, some of you want heart shapes. Thereâs no judgement here. Just promise us, right here, right now…promise yourself…that you wonât buy a diamond you donât absolutely, positively love. After all, it will be on that finger forever. Youâre the one who has to look at it every day.
This Isnât A Test
Ultimately, buying a diamond engagement ring is a very personal choice, and thatâs the way it should be. Forget the brand names (unless thatâs super duper important to you), forget what the bridal magazines tell you, forget what your mom thinks. This is likely going to be one of the biggest purchases of your life, when it comes to both money and meaning, so you have to go with your gut.
