Very small pearls for fine details, delicate layering, and seed-pearl work.
4–6mm
Small, lightweight pearls for minimalist jewelry, bracelets, and layered designs.
6–8mm
A balanced everyday range for necklaces, earrings, and broad commercial collections.
8–10mm
A stronger visual scale for premium pieces and statement details.
10mm+
Large focal pearls for pendants, rings, statement earrings, and sculptural designs.
How to Choose
- Start with the intended design and wearing comfort.
- Compare luster, shape, surface, and drilling together with millimeters.
- For pairs or repeat production, confirm the actual lot and matching tolerance.
FAQ
Are larger pearls always more expensive?
When other quality factors are equal, larger pearls usually cost more. Luster, surface, shape, color, and matching can still outweigh size.
