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.

Cute but Wrong Color

Style: July - Ruby

These earrings are really dainty and pretty, and my daughter loved the style. Unfortunately, the color wasn’t quite right for her birthstone—her ruby birthstone is a deeper red, but these leaned more toward red-orange. They still look nice and could work for other occasions, but we were a bit disappointed since we were hoping for a true ruby match.
