I would give this about 3 1/2 stars.  The product is pretty and dainty.  The measurements are there.  Take a peak and get a sense for how big it is. It's sterling silver and very reasonably priced. It'll be a great gift.

However, there are a few thing to know...

1-The product says it ships in 48 hours, but it is coming from Israel -- not in any fine print I saw.  I often just expect that an amazon order will be coming from the US.  With USPS, you can often expect something in 3-6 days, but the fastest you will get this necklace is 10 business days after shipping and quite possibly longer so plan in advance and buy early.  They have quick shipping, but it's price prohibitive.

2-The seller requires a signature for delivery.  My post office is open the same hours I work so it's difficult to get to the post office and may take a couple extra days if you need to wait until weekend hours or such.

It worked out for me, and I am happy with the purchase.  I wish I had a few of these details up front.  I may have ordered earlier for my niece's birthday.
