I have some brown freshwater pearl studs and necklace. I wanted a ring to match, but actual brown pearls are too costly for only occasional wear.  When I stumbled across the brown pearl shell, with a 20% off coupon, I couldn't resist.  The "pearl" is huge!  I wouldn't wear this on a ring finger, but on my middle or index the large size is not too much.  The color is rich; the silver is bright.  The pearl is also very securely attached - it is not simply sitting in the setting.  Under one side, the pearl is drilled and a pin is soldered to the ring.

Overall, this was definitely worth the $16 I paid, and I would have paid $20 (the current price as of this writing).  Please see my pictures of the actual ring I received.  Highly recommended!
