The blue stone is bigger than what is shown in the model photo. I did not bother with the cm measurement (0.9cm or .4") as I went with the photo of the model wearing the earrings as my size indicator. Not the seller's fault, but my own. The photo in the listing showing the earrings against a hand are a truer representation of size. I was looking for a very petite and small stone half the size of these, so these are twice the stone size of what I wanted. Take the time to verify the measurements that are provided (0.9 cm, or .4"). The color is beautiful, but if the size of the blue teardrop matters, do your homework. I plan to gift them as they are not my style at this size. They come in a nice gift-able blue box, blue storage bag, and cleaning cloth.
