I got this square pendant necklace for my wife.  The necklace arrived in a nondescript package which contained a small black presentation box.  The pendant looks pretty much like what you see in the picture.  There are citrine and peridot stones complemented by a tiny 0.01 carat center diamond.

The chain is a very thin, 18" chain with a spring ring clasp.  I thought it was too thin but my wife thought maybe it is thin on purpose so it won't distract from the pendant.  Even so, we both agree it would probably be easy to break, and/or tangle.  The gold, 18K plate over sterling silver, looks fairly good.

The drawback to the pendant for me is the center set stone.  It is too tiny to add any real sparkle  However, if you like citrine or peridot, this is a nice, relatively inexpensive necklace.  Be aware there is also a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/ring/dp/B009EK3NF6/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">ring</a>&nbsp;that complements the necklace.
