This is a beautiful, handmade promise ring from 55Carat. The centerpiece is a genuine, natural oval-cut gemstone – and you get to choose the stone! They have a huge selection: Amethyst, Black Onyx, Citrine, Blue Topaz, Emerald, Garnet, Iolite, Moonstone, Smoky Quartz, Rose Quartz, Peridot, and many more. The band is made from solid .925 sterling silver, so it's quality metal. The ring is fully customizable. You can choose your size (from 5 to 12, and they can even do half sizes or custom sizes if you message them), and you can select the metal plating (silver, gold, or rose gold). It's a thoughtful, personalized gift for a birthday, Valentine's Day, anniversary, or just because. Since it's handmade, allow a little time for production. A unique piece of jewelry that lets you pick exactly the right stone and fit.
