Very nice gift necklace
Color: 10-Oct-Lab Grown Pink Sapphire, Style: L
Honestly - I found this to be of equal quality to the well known brand necklace of the same type (birthstone and initial) that I also bought - and this one cost less. It looks lovely. It made a great gift for my niece. The chain is quite delicate - but most of them are, these days. I definitely recommend for the younger ones in your life - teens on down. It was a big hit.

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.
