This delicate, sparkly 3 stone ring looks great alone or added to your daily stack! 14K Gold Filled Double Band is 2mm, CZ stones are 3mm Sizes 5-8 Gold Filled has 100 times more gold than gold plated jewelry and will not chip or fade with wear! You can swim/shower, etc just like you would with solid gold. Gold filled wire is created by taking a sheet of 14 karat gold and bonding it through extreme heat and pressure to a core of semi-precious metal (brass). This is a very sophisticated process and only a few mills in the world do it. You should not mistake this process for gold plating as there is a very big difference.
