These beautiful handmade red drop earrings have sterling silver hooks and a handmade silver knot above each piece of red recycled sea glass. Each piece of recycled sea glass is slightly unique in size, color, and opacity; nevertheless, very much what you see in the product shots. When held up to the light, the color of the glass is light red. When against skin or clothing, it appears dark red. Each purchase includes an inspirational pop-open card within each box, making your purchase or gift even more special. These natural, nautical, earrings are perfect for yourself or given as a gift. Sea glass may have tiny bubbles within the stone. This is normal and adds to the beachy charm of the necklace. Please do not wear in pool or hot tub as harsh chemicals may harm jewelry.
