After I tool the sterling silver earrings I put a hole in the bezel so the light goes thru the transparent stones. It gives them more color, more character. They actually glow. All the stones are real stones. The only exception is the sapphires are lab created (as real sapphires are more expensive then diamonds!).
All the earrings come with sterling silver lever back wires. These are the very best. They have a secure back. So when you take off your sweater or go for a hike or airplane ride you still have your earrings. This is half the battle of not losing your earrings.
