Gold fill UV sea glass size 6.5

I find all my sea glass in the central coast of California. Sea glass set in 14k yellow gold fill. This one is super cool UV sea glass, so it will glow in a black light! 

Gold-filled jewelry has 100x more gold alloy than gold plated and because that layer is so much thicker, it means gold-filled jewelry lasts longer and stands up to wear and tear better than gold plated. All it would take is one small scratch on a gold-plated piece to expose the jeweler's brass underneath. As long as the piece is well cared for, gold-filled jewelry can last a lifetime.
