Perfectly unique jewel encrusted bands are hand fabricated using the highest quality 925 purity Sterling Silver which is completely Nickel free. The solid square stock (8 gauge) band measures 3.25mm wide x 3.25mm thick. The 2.5mm round brilliant sparkling colorless "Swiss" cut Cubic Zirconia are mixed with 2mm round brilliant cut lab created blue Sapphires, red Rubies, green Emeralds or any other color combination you may desire . The gemstones are deeply gypsy (flush) set smooth and secure along the top portion of the band as well as the sides of the band hence creating the "Peek A Boo" accent stones. I wear mine as a thumb ring and receive many compliments! Each one of my eternity bands is hand crafted to your specifications in turn making them as unique and lovely as the special recipient.
