Hi
@eletons!
This is for you and any others who are interested in akoya pearls and want to better understand how size and grading affect price.
I just remembered JRDunn, a jeweler in South Florida, carries a lot of Mikimoto on their website (most websites only carry a few pieces). Here are pearl stud earrings which you can select grade and size to get an idea of pricing.

As a recap on akoya pearls...
Akoya pearl sizes vary from 5.5mm to 9.5mm, the largest akoya is 9.5mm.
Pearl grades vary from A to AAA. The highest pricing will be 9.5mm, AAA. Pearl overtone does not affect pricing.
You can click on the website to price out some pearl studs to see pricing.
I've listed three examples of pearl earring stud for a quick summary.
- Pearl size of 7.5mm - For Grade A, price is $670.00. For Grade AAA, price is $1,590.00.
- Pearl size of 8.5mm (8.5mm begins the jump in price). For Grade A, price is $1,730.00. For Grade AAA, price is $4,250.00. Notice how for only 1mm increase, from 7.5mm to 8.5mm, the price increase is over 2.5 times.
- Pearl size of 9.5mm (largest akoya size and the rarest). For Grade A, price is $6,060. For Grade AAA, price is $21,740. Notice how for another 1mm increase, from 8.5mm to 9.5mm, the price increase is much more significant, over 3-5 times. This is due to the rarity of the pearl.

You can see how pricing varies greatly. Therefore, I highly recommend getting a certificate if you plan to purchase Mikimoto. By the way, JRDunn is a reputable jeweler. They are based in Ft. Lauderdale, Florida, which is a city north of Miami (I grew up in Miami

). I checked for you, and they ship to Europe! I also noticed on their website it's 15% off the first purchase.
I wanted to share this as it might help you decide what strand/earrings you want. I also thought this might be helpful to any others interested in purchasing Mikimotos.
I recall you were looking at a long strand. Here is the link to a 32." You can play with pearl size and grade. There are other shorter lengths too on the website, 18", 20", etc... You can have fun surfing and playing!

Hope this helps. Good luck to you on your Mikimoto hunt!
