Flawless Diamonds

When you're looking for a diamond that's truly flawless, look for an IF or FL clarity grade. Internally flawless (IF) diamonds are free of inclusions under 10x magnification, but they may contain some surface blemishes. A flawless (FL) diamond shows no inclusions at 10x, and they’re very rare—fewer than 1% of all diamonds receive an FL clarity rating. Flawless diamonds are incredibly rare, because most diamonds feature naturally occurring inclusions. IF and FL are the top tiers of clarity grade, each accounting for just six percent of diamond sales.

FAQs about Flawless Diamonds

All of the 4Cs contribute to the final price of a diamond. Of these, carat weight plays the biggest role, but choosing a diamond with an IF or FL grade will definitely increase its price, since it’s so rare.

The value of a diamond depends on factors like cut, colour, and carat. While both IF and FL diamonds are valuable, which you choose should depend on your preferences and your budget.

Yes. Not only is the clarity grade included in the report, but there's also a map that will indicate the location of any internal or surface inclusions.

When a diamond is called "eye clean," it means the inclusions are so minor, they can't be seen without magnification.

Yes. Any diamond with a brilliant-cut pattern, such as round, princess, pear, heart, and marquise, will hide blemishes better than the other fancy shapes, such as Asscher and emerald.

Flawless Round Cut Diamond Review

.51 ct flawless diamond 10k ring

I am deployed and want to ask my girlfriend to marry me when I get back home. I thought about purchasing a ring overseas. Then I started doing some research. I found blue Nile. I didn’t use a consultant. Some of me wishes I did, but i think I did pretty good. From what BN says, they say go for a vs or si diamond. There quality photos steered me away cause you could see the flaws that were there. I chose a near colourless diamond and IF clarity and it is amazing. For the price I could have went bigger. But I can’t be any happier.

The ring was absolutely stunning. The diamond was exactly what I ordered; colourless, near flawless; and mesmerizing. The blue and red brilliance are outstanding. She couldn’t have asked for a better diamond nor a better setting. She absolutely loves it!

Exquisite Ring, Perfect Price

After going to numerous jewellers in my area (Kay, Zales, Shane Co., etc.), I found myself disappointed at the quality of the stones and rings in my price range. I researched Blue Nile after hearing about them and being initially suspicious of their lower prices. My research left me satisfied that the company was a high quality establishment and after visiting their showroom I was certain I would be buying from Blue Nile. The ring I purchased is incredible. The diamond they found for me is perfect (flawless actually) and within my price range. They listened to what I wanted and didn’t try to upsell me. None of the sales associates work off of commission so they were there to help me. I loved the buying experience and would 100% recommend this place to anyone no matter what budget they’re working off of. Blue Nile will help you and leave you very satisfied with your purchase.
