Citrine Sterling

which gemstone should i get?
im going to get this necklace and you can choose the stone put on the necklace ( stone selection on bottom of page ): http://www.sterlingsilverart.com/p787/EXACT-REPLICA-VERSION-Sterling-Silver-Locket-Pendant-like-a-Merm/product_info.html?osCsid=f3f2dedc9af15e7fb61f748cd2fb8dbd — please help me figure out which one to get —- i kind of like the Black Onyx, citrine, zambian emerald ( +$8.00 ), and the turquoise — which stone do you think looks best — help
I think the turquoise because it looks really genuine because it a very earthy stone and the color is beautiful. also, I thing it would look soo nice with that type of jewelery. it depends on wich hair color too I guess it would look best with dark hair because of the contrast but brunettes can pull it off too.. garnet would look best with blondes. I love this… might buy it myself!!!
