When shopping for diamonds—whether for a ring, earrings, or other jewelry—it’s common to come across various carat weights. One popular and affordable choice is the 1/4 carat diamond, offering subtle sparkle without the premium price of larger stones.

But how much is a 1/4 carat diamond worth? And how does it compare to other sizes like 1/10, 1/3, or 1.5 carats?

Let’s dive into the details.

What Is a 1/4 Carat Diamond?

A 1/4 carat diamond (also written as 0.25 carats) weighs 0.05 grams or 25 points. In the jewelry world, this is considered a small yet noticeable size—perfect for solitaire studs, petite engagement rings, or minimalist pendant necklaces.

How Big Is a 1/4 Carat Diamond?

The size of a diamond depends on its cut and shape, but in general:

A round-cut 1/4 carat diamond measures about 4.1mm in diameter.
In contrast, 1/10 carat diamonds are about 3.0mm, making 1/4 carat significantly larger.
1/3 carat diamonds are typically around 4.4mm, slightly bigger than 1/4.
A 1.5 carat diamond measures closer to 7.4mm, much larger by comparison.

Which Is Bigger: 1/10 or 1/4 Carat Diamond?

1/4 carat is bigger.
1/4 carat = 0.25 ct
1/10 carat = 0.10 ct

That means a 1/4 carat diamond is 2.5 times heavier than a 1/10 carat stone and looks significantly larger.

Which Is Bigger: 1/3 or 1/4 Carat Diamond?

1/3 carat is bigger.
1/3 carat = 0.33 ct
1/4 carat = 0.25 ct

While the size difference may not seem huge, a 1/3 carat diamond has a larger diameter and slightly more visual presence than a 1/4 carat stone.

Which Is Bigger: 1/4 or 1.5 Carat Diamond?

There’s no contest here. 1.5 carats is six times larger in weight than a 1/4 carat diamond, and it appears much larger visually.
