This glass heart pendant has a lot going for it.  The Singapore chain is sturdy, and the pendant is a substantial size, about the size of a quarter.  It's a deep red, so deep it almost seems Goth, but this is not a Goth pendant.  The chain and marcasite are highly faceted, and it really sparkles, yet it isn't gaudy.  This is made in China, but still, it's one of the sturdiest pieces of jewelry I've received from Amazon.

Yes, it would make a nice gift, as long as you don't forget that it's glass, not a gemstone.  I think it's very pretty, and plan to buy at least one as a gift.
