Awesome Tungsten Carbide band ring in beautiful brush finish ion plated black tungsten with beautiful anodized aluminum purple inner band and matching recessed purple stripe. Comfort fit band - slightly domed inner band. Beveled edges - style and shine. Natural unplated tungsten carbide is bright silver when polished. The black in this ring is created via an advanced ion-plating process. Outer band of superior quality tungsten carbide. Inner purple band of superior quality anodized aluminum (tungsten carbide cannot be plated violet purple). Colors are added to aluminum via a dying process immediately after anodizing. Because tungsten carbide rings cannot be resized and returned engraved rings are all destroyed, please choose your ring size carefully. If you are unsure of your ring size, we recommend going to at least two local jewelry shops to have your finger measured. Please specify you are looking to purchase a "comfort fit" ring. If going to a jewelry shop is difficult, please use a ring sizing guide available all over the internet including the famous jewelry brands. There are also many YouTube videos that demonstrate the proper way to measure a finger. Comes with a deluxe gift box. As always, thank you for looking at our listing.
