I've had a dark gray pearl necklace for years and decided to make it part of a set: necklace, ring, and earrings.  I purchased a ring and it's a lighter mid-gray, than the necklace which is a dark gray.  OK, I didn't really expect success without special ordering through a jeweler who could see the necklace..  Then I ordered these earrings and to my surprise while they didn't match the necklace either they are a perfect match for the ring!  I decided it just didn't matter if the necklace was made of dark gray pearls and the other two pieces of mid-gray pearls because they each have their own beauty.  These are just simple button earrings, they have good luster and size and are most appealing and pretty in their simplicity.  I'm happy and would recommend them to anyone.
