Mix up your look during the festive season with this peridot crystal necklace. Emerald is the popular choice for Christmas but we think the subtle shade of peridot is a pretty alternative. The chain is a classic diamond cut curb and measures 16 inches, with an additional 2 inch extender if you prefer it to hang a little lower. It features 9 identical stones, each one measuring 4mm. Peridot is the birthstone for August, so pair this with a pair of peridot crystal studs to create the perfect birthday gift!
