FAQs about Size 3 Engagement Rings

A size 3 engagement ring measures 14.1mm in diameter. A size 3.5 engagement ring measures 14.5 mm in diameter. Blue Nile's ring size chart breaks down the dimensions of each size.

As you shop for an engagement ring, consider that wider bands can feel more snug on the finger than a smaller band. If the band is wide, consider going up by half a size.

Sneak a ring she already owns, and place it on top of our printable ring size chart. Measure the inside of the band against the different size options. When the ring falls between two sizes, opt for the larger of the two.

Most engagement ring designs can be resized. Resizing is free for the first year at Blue Nile—as long as the design permits.

Size 3 Engagement Rings Review

Perfect for small hands/ring sizes

Best Value Diamond! I got recommendation for engagement ring from the jewelry expert at the showroom. Jeanie at Garden City chose the best diamond out of the options that I had. It looks gorgeous on the ring as well. We had a little problem because my fiancee's finger was wayyy smaller than the smallest option (size 3) that were available on the website. The Blue Nile customer service took only less than 2 weeks to make the ring smaller than 3. What a service to a customer with a uncommon request. I had best experience there. I will definitely come back for our wedding rings) not found.! Thank you Jeanie!! and Thank you Blue Nile customer service!!

Perfect for small hands/ring sizes

First off, Petite band means it's about 1/3 the width of a regular band. This ring would look puny on large hands and ring sizes. My fiance is a size 3 3/4 and the ring is a perfect width for her. I was worried that getting a regular width, when paired with a wedding band, would take up her whole knuckle, so Petite was the way to go for us. I was also worried that what you see online isn't what you get. It's much better looking in person. The side diamonds sparkle so much it's kind of annoying (to me, but she loves it). Because the band is so narrow, you might have to get a smaller size than what your regular width band would be. We did have to get the original ring resized down to 3 3/4 and that process was relatively easy. Only had to pay for shipping to Blue Nile, they shipped it back free.

Beautiful elegant emerald cut ring

I have been looking everywhere for a beautiful emerald cut 1c diamond. Every ring I’ve looked at either had little diamonds all around or the diamond was too big or too expensive. This ring is elegant and just perfect. My fiancé has small hands and she didn’t want diamond all Read more about review stating Beautiful elegant emerald cut ring
