rhodium .925 Sterling Silver Blue Topaz Cubic Zirconia Ring eternity band  I have only have it a day , so I can not tell you how well it hold up , but it be a very pretty ring ! the stone actually look a little darker in person than they do in the picture -lrb- of course , computer screen vary -rrb- but I really love the color , which be a couple of shades lighter than a royal blue . the ring sparkle nicely , and have a good fit . very comfortable ... Gem Avenue ship the item quickly , and I actually get the ring within 3 business day use only the basic shipping method ! I will definitely purchase from they again ! good buy !
