Very cute
Color: 06-June-Lab Grown Alexandrite, Style: E
These are very nice quality and durable. I purchased this for my daughter's friend. it is really nice with birth stone and initial, perfect for gift. Perfect chain length and clasp nicely. It does not look cheap, but also affordable. It came with small card you can write, which is really nice touch. It also came with beautiful box. Again, it is super nice gift for any occasion. It is suitable for all ages. I highly recommend.
