The Most Popular Size Pearl Necklaces and Earrings
1. Japanese Akoya pearls are measured in half-mm increments (i.e. 6.0-6.5mm, 7.0-7.5mm, and up) and the most popular size of Akoya pearl necklace is 7.0-7.5mm.
2. Freshwater pearls are measured in 1.0mm increments (i.e. 6.0-7.0mm, 7.0-8.0mm and so on), and the most popular size of Freshwater pearl necklace is 7.0-8.0mm
For a classic pearl stud earring, the same 7.0-8.0mm size range is also our most popular choice. Elegant and versatile, the 7.0-8.0mm pearl stud sits squarely on the earlobe without falling forward or putting too much weight on the ear. This size range can also accommodate second piercings a little higher up without crowding out the next earring, which is a common concern today.
Pearl Necklace Size ComparisonThe photo below shows the most popular Akoya pearl necklace sizes from 6.0-6.5mm through 9.0-9.5mm. Each half-millimeter increase in size may not seem like a lot on paper, but keep in mind that pearls have volume as well as diameter. A single half-millimeter increment increase can mean as much as 20% increase in overall size! Compare the first top two strands (6.0-6.5mm vs 6.5-7.0mm) to get an idea of how that 0.5mm measures up in real life.
Pearl sizes from top to bottom are: 6.0-6.5mm (top strand), 6.5-7.0mm, 7.0-7.5mm, 7.5-8.0mm, 8.0-8.5mm, 8.5-9.0mm and 9.0-9.5mm (bottom strand).

10-11mm Pearls On Model:
The 10.0-11.0mm size range consists of large Freshwater, Tahitian and South Sea Pearls. Freshwater pearls will be fairly uniform in shape and size, graduating from 10.0-11.0mm, while Tahitian and South Sea strands will be graduated (i.e. 10.0-12.0mm, 10.0-14.0mm, etc.). These larger pearl sizes are very luxurious and very glamorous!
Large "Exotic" Strands: Tahitian and South Sea Pearl NecklacesThis category of necklaces features larger pearls in natural shades of black, white and gold. These pearl types are considered "luxury" pearls, and range in size from 9.0mm to 15.0mm and larger: so Big Pearls!
They'll typically be "graduated" in size, so a strand might be labelled as 9.0-12.0mm. What that means is that the pearls progressively get larger from 9.0mm at the clasp to 12.0mm in the center and so on.
Below are pictures of some of our "exotic" strands showing what pearl graduation looks like.
This White South Sea pearl necklace below graduates from 10.0-13.0mm approximately.
