I am looking online at a ring that has a center stone that is 3/8 of a carat…it is a preloved ring…

What is the equivalent of a center stone that is 3/8 of a carat? Please help, I am bad at math…

Thank you!

3/8 in inches is equal to .375 when you want to know what 'hundredths are. I think I have given you correct info.

3/8 carat is less than half a carat.

It would be just a tad below a half ct. What shape stone?

I have a .50ct loose round that I could take a pic of on my finger if that would help.

This is correct
.375 so less than a half carat.

Yes, but 3/8 refers to weight, correct? It would depend on how well-cut the diamond is? Also, ct weights are different for different gemstones. I'm asking, not telling. I'm wondering myself.

I'm sorry, I didn't make my comment very clear. I just meant that the ct weight would differ in size due to the shape and how well the stone is cut and if it is a diamond, sapphire, etc. Haha! I've had a crazy day!

3/8 = 0.375 which means it is just under 0.4ct

But the carat does not necessarily tell you the actual size of the diamond in mm. For example you could have a "1ct" diamond that is either smaller or larger than a perfectly cut 1 carat diamond.

Diamdb.com is a great website which you can use to compare diamond sizes:

0.37ct Round (4.67×4.67×2.82) vs 0.5ct Round (5.16×5.16×3.11)

Compare 0.37 carat Round (4.67×4.67×2.82mm) vs 0.5 carat Round (5.16×5.16×3.11mm) on actual diamond size and finger coverage (17.13mm² vs 20.91mm²)

From what I can look up, 3/8 ct. will be between 4.5 mm and 5 mm. This probably won't translate to fancy shapes. Are you looking for an actual size or just an idea of how it will look?

Both. The stone is a round brilliant cut.

Ask the seller to fire up the calipers and measure it.
Some vendor, Brilliant Earth maybe? shows their rings in various carat sizes on a size 6 hand. It's helpful to get an idea. What is your ring size and what kind of ring are you considering?

@sugarcloud, Your first paragraph is what I was trying to say in my uneducated way.
