A One Carat Diamond on a Size 2 or a Size 10 Finger – Review

By Calla Gold

This Beautiful 1ct. Diamond Looks Nicely Gigantic on Her Size 2.5 Finger

Your Finger Size vs. That Center Diamond Size

“My girlfriend said she loves the one carat size of her best friend’s engagement ring. But Trina is like a size four and Becky is an eight and a horsewoman.

Do I just get her a one carat diamond, or do we scale it up for her size?” Bertram was an engineer and he got me to thinking.

Here is a 1.20ct. Round Brilliant Diamond on a Size 8 Finger

I’ve sold one caraters again and again and they’ve always looked a bit different on each woman who wore it. This is based on the finger size, and the design chosen.

I had never looked deeper except to mention that people should contemplate the look they want on their hand not the picture in the magazine.

Then I found!

Diamond Size, Shape and Finger Size Options

Finding was a happy event for me and perfect timing.

I spent time looking for 1ct and similar sized diamonds on different sized fingers on the website. I share them with you to compare.

If you have a larger size finger, it’s a fun reason to go with a larger diamond. But it is not a requirement.

This Size 9 Wedding Set Has a 1.10ct Center Diamond

Compare the picture at the top left of the size 2.5 woman in a 1ct. and this picture. It’s super helpful to be able to compare a style on a hand and know the finger size. A one carat diamond just factually looks bigger on the size 2.5 woman than on the size 9 woman.

It’d be very helpful in choosing favorite details to see how those details look on someone with your skin tone, your finger size and even a similar finger shape. That is the strength and helpfulness of the pictures submitted to

A Halo Makes Your Diamond Look Bigger

If you have a particular size in mind and your budget says, “nope, you need to go a bit smaller than that,” consider adding a halo or even a double halo.

This diamond is under a carat and surrounded by a double halo.

This ring Has a .25ct center diamond with a nice bold halo and intertwined band. She is a size 9.

Size 6 with a 3 carat Morganite with a halo.

Halos can be tiny or bolder depending on the size of the diamond and your finger size.

Comparing Vintage Styles on Different Finger Sizes

Her size 7.5 finger loves the width and engraved detail of this vintage setting for her 1.02ct diamond.

This size 9, ring in the vintage style has a 1.10ct round center with a halo and two side diamonds.

She is size 6 with a 1.37ct. vintage style width ring.

This size 5 vintage ring has a .50ct diamond in the center.

Skin Tones and Your Style

One of the things I love the most about is the fact that there is a skin tone filter. We all look different and it’s super cool seeing examples on different skin tone types. I feel like that is missing from the ads I see.


This size 6, 1.30ct. center diamond engagement ring has a tiny halo.

This Size 5 Ring has a 10.05ct round brilliant diamond in it. No halo needed.

She’s size 4, with a three diamond engagement ring with a 2.70ct. center.

What About Bertram?

He went for a 1.45ct. round brilliant and had me set it in a semi-bezel so she can ride and be at the stables with it. Dude is smart!

I hope you find as helpful as I do.

  1. My engagement ring is a size 6.25 with a .73 round brilliant diamond, no halo. I didn’t want anything bigger and the under a carat is just perfect. I also went with yellow gold as it was much warmer and don’t regret it.

    • Hi Nancy,
      Thanks for telling your size of finger and the diamond that you chose. It sounds beautiful. I took chose yellow gold to go with the diamonds on my wedding ring. The warmth is pleasing to me too.
      Your Personal Jeweler,

  2. Thanks Calla for sharing such a detailed post on sizes of fingers and diamonds. Superb content, keep shining like a diamond! Thanks once again…

  3. I never thought about it, how a one carat diamond looks on different size fingers. It is such a good thing to check out. In trying on my best friend’s engagement ring, her 1.60ct. round diamond looked smaller on me than her as my hands are bigger.
    Guess I’ll need a 2ct. diamond.

    • Hi Tracey,
      That cracked me up. Two carats! I’m glad you enjoyed the article.
      I was really happy to see all the different pictures of diamond sizes and finger sizes. It was like something in the back of my mind that I knew came into focus and made so much sense.
      Enjoy your beautiful diamond when you get it.
      Your Personal Jeweler,
