Pearl Size Guide
Pearls are measured in millimeters and the size significantly affects their overall look.
| Pearl Size | Look & Description |
|---|---|
| 3–4 mm | Very delicate, subtle everyday pearls |
| 5–6 mm | Classic and timeless, ideal for daily wear |
| 6.5–7.5 mm | Refined presence, elegant and balanced |
| 7.5–8.5 mm | More prominent and luxurious |
| 8.5–9.5 mm | High-end, noticeable, premium look |
| 9.5–10 mm+ | Statement pearls, formal and rare |
Akoya pearls commonly range from 6–8 mm and are known for their mirror-like luster.
Pearl Necklace Length Guide
Pure Pearls notes that the Princess (18") is the most popular pearl necklace length and typically sits just below the collarbone.
| Length name | Inches | How it wears |
|---|---|---|
| Choker | 16" | Close-fitting, elegant |
| Princess | 18" | Most popular; sits below collarbone |

| Opera | 28–36" | Long; can be doubled/layered |
Common Pearl Necklace Clasps
A very common visual style in pearl jewelry is the smooth oval / bean silhouette—often done in sterling silver—because it keeps the back of the necklace clean and minimal. You may also see this referred to as a “bean clasp” in pearl hardware.
