Pearl types compared
Six side-by-side comparisons of the pearl types people ask about most. Each one covers size, color, luster, where the pearls come from and typical price, so you can see which suits your budget and style.
All comparisons
The four main types in brief
| Type | Typical size | Common colors | Price |
|---|---|---|---|
| Freshwater | 2-12 mm | White, pink, lavender | Lowest |
| Akoya | 2-10 mm (most 6-9 mm) | White, cream, silver-blue | Moderate |
| Tahitian | 8-14 mm | Dark gray, green, peacock | Higher |
| South Sea | 9-20 mm | White, silver, gold | Highest |
Sizes and prices overlap, and quality (luster, surface, shape and matching) affects price as much as type does.
Natural vs cultured
Almost all pearls sold today are cultured: a farmer starts the pearl, and the oyster or mussel grows it. Natural pearls form without help, are very rare and are mostly found in antique jewelry.
How to compare two strands
Look at them side by side in daylight. Good luster shows sharp reflections. Check for spots or dents, how round each pearl is and how well they match along the strand. Ask the seller for the pearl type, size range and any treatments in writing.
