My husband bought this for me for Christmas, and I love it.  The stone is a dark glittery blue, but often looks black or even purple depending on the light. The marcasite setting really stands out.  The picture provided by Amazon is very accurate - what you see is what you get.  And, it looks great with sapphire jewelry.

Thankfully, Amazon's "recommended also" feature popped up matching earrings for my husband - and he duly bought them for me.&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Sterling-Silver-Marcasite-and-Blue-Gold-Stone-Drop-Earrings/dp/B000SMPOCE/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Sterling Silver Marcasite and Blue Gold Stone Drop Earrings</a>.  The set is fantastic, and definitely worth the price.  Please see my pictures.  Highly recommended.
