Solitaire Earring Size Guide: How 0.5, 1, 1.5 and 2 Carat Look on Real Ears
When you are buying a solitaire earring online, the first question you have is: what size will actually look good on me? You can read every millimetre chart on the internet and still feel uncertain — because what matters is how the stone looks on a real ear, not on a white background.
So we filmed it. In the video above, Vai Ra's founder compares 0.5, 1, 1.5 and 2 carat round brilliant solitaire studs side by side, worn on an actual ear, so you can see exactly what you are choosing between before you buy.
What the size comparison shows
0.5 carat vs 1 carat
The jump from 0.5 to 1 carat is the most dramatic size difference in the range. A 0.5 carat round brilliant measures approximately 5 mm in diameter — delicate, minimal, and ideal for everyday wear. A 1 carat sits at around 6.5 mm — noticeably larger, still classic, and the most popular size for a solitaire stud that works for both daily wear and occasions.
1 carat vs 1.5 carat
The difference between 1 and 1.5 carat is subtler than most people expect. A 1.5 carat round brilliant measures approximately 7.4 mm — you will notice the extra presence on the ear, particularly in photographs and in light, but it does not read as dramatically different in person the way 0.5 to 1 does. If you want a stud that photographs beautifully and has clear presence without being statement jewellery, 1.5 carat is the sweet spot.
1.5 carat vs 2 carat
At 2 carats, the round brilliant sits at approximately 8.1 mm. This is unambiguously a statement earring — high visibility, strong presence, and the kind of size that gets noticed in a room. The difference from 1.5 is clearly visible both in person and in photographs.
Solitaire earring size comparison — at a glance
| Carat weight | Approx. diameter | Best for |
|---|---|---|
| 0.5 ct | 5.0 mm | Everyday wear, minimalist style, first solitaire |
| 1 ct | 6.5 mm | Classic everyday-to-occasion stud, most popular size |
| 1.5 ct | 7.4 mm | Elevated everyday, photographs beautifully, sweet spot |
| 2 ct | 8.1 mm | Statement earring, occasions, high visibility |
All measurements above are for round brilliant cut stones. Actual appearance on the ear also depends on your earlobe size and the setting style — which is why the video is more useful than any chart.

What size should you choose?
If you are buying your first solitaire stud and want something you will wear every day without thinking about it — start at 1 carat. It is the size that works in every context, reads as clearly intentional jewellery, and does not feel excessive for daily wear.
If you already own a 1 carat and want to upgrade, or you are buying for a specific occasion — go to 1.5. The difference is meaningful without crossing into statement territory.
If you want to be noticed — 2 carat is exactly what it looks like in the video.
