A lot of brides-to-be are stuck choosing 0.8-carat diamonds lately. A client sent me GIA certificates of four different stones from Blue Nile and asked me which one is worth buying.
Fun fact: all four diamonds are graded 3EX, but their actual fire, clarity and visual performance are super different.
I’m breaking down every detail today so you guys can skip the bad picks and choose the best one easily.
Diamond 1 & 2: Similar specs, just average performance (go with the 0.81ct)
These two Blue Nile diamonds have almost identical parameters and cut proportions. Both have pretty high crown angles, which makes their total depth ratio larger than normal.
Even with a full 3EX lab grading, this kind of cut limits light reflection. Compared with other standard 3EX diamonds, their fire performance is just mid, no outstanding sparkle at all.
Also, both are VS2 clarity, with cloud inclusions as their main flaw. Clouds definitely hurt transparency a little, leaving a slight hazy risk on the stone.
If you really have to pick between the two, the 0.81ct one is better in overall quality and value.
Diamond 3: Hard pass — high milky diamond risk
This one I would never recommend. It’s also VS2, but its only inclusion is cloud. This is a huge red flag for milky diamonds, and the chance of foggy, hazy appearance is extremely high.
Its cut proportions are way off ideal range too. Table ratio, total depth and pavilion angle all exceed premium standards, which really kills the diamond’s fire and brightness.
It’s obvious the cutter sacrificed perfect cut just to keep a bigger carat weight. Totally not worth your money.
Diamond 4: The best pick out of all four
This diamond beats the other three by a lot. It has no cloud inclusions at all, so zero milky or hazy issues, and the transparency is super clean.
Its cut proportions are well balanced, with excellent fire and light performance. It looks bright and sparkly for daily wear all the time.
If you’re choosing a 0.8ct diamond on Blue Nile, just go with this one, you won’t regret it.
The 3 quick diamond takeaways
1. 3EX cut doesn’t mean perfect! Bad proportion still ruin sparkle.
2. For VS2 clarity, always check inclusion type. Single cloud inclusion = high milky risk.
3. Avoid diamonds with high crown angle and oversize depth, they always look dull.
Don’t blindly follow diamond parameters. If you don’t understand your GIA report or need help choosing Blue Nile diamonds, feel free to send me your certs for free consultation!
