This Sterling Silver and Larimar ring is from Marahlago's Atlantic collection and it has sparkling Blue Topaz on each side of the Larimar stone. Marahlago is the top designer in Larimar and warranties all pieces for 3 yrs, and they always use an abundance of Sterling Silver in all their. Please note that I have already reduced most items from their original selling price and because most of my listings, unless otherwise stated, are New Never Worn, I can not reduce them much more. Thank you
