New, larger stud earrings are great for every day wear. Gray and turquoise are a great combination to wear as a neutral. I made the lampworked glass squares myself by melting glass rods at a torch and layering the shades of molten glass and shaping it into a square. I then set a sterling silver post. The post goes through all the way through the glass so there is no risk of it falling off.
Your earrings will come with large sterling silver backs that will support the earrings in your ears so they will not tilt forward.
The earrings will arrive in an attractive gift box.
