FANTASTIC!
Style: November - Citrine
I have received a fair amount of crap earrings from Amazon, but these earrings are wonderful! Arrived very nicely packaged and are of great quality and even more beautiful than online! These are so nice I would actually give them as a gift! I will try to order more earrings from this specific vendor!

love the color and true color of these earrings!
Style: January - Garnet
I am lucky to have a red birthstone because red is my favorite color! These earrings did not disappoint me, the red stone is not huge but I wanted small earrings that would still show up and give me a little sparkle. These earrings match the necklace I got first with the same design. I am happy with these pretty earrings. I also appreciated the good price and quick delivery and will buy from this vendor again.

Rapunzel earrings
Style: June - Alexandrite
I got these earrings as a gift because we were going to Disney and I wanted to dress up like Rapunzel and these were perfect for the look. They are also small and comfortable.
