These simple, dainty stud earrings are so versatile, and will compliment just about any outfit! The genuine 10mm Iolite stones are hand wrapped with your choice of 22 gauge sterling silver, stainless steel or gold filled wire. The earrings will come on an earring card with sterling silver, stainless steel or 14k gold filled earring backs, and packaged in a charming box, perfect for easy gifting! Iolite, also known as Cordierite, is a Gemstone that displays an optical phenomenon when observed at different angels, causing it to display shades of blue, violet and gray. Iolite is also often called Water Sapphire. All my jewelry is handmade and made with patience, care and love.
