This is a handmade necklace with a unique pendant top. The cord is leather-like. Length is adjustable. The glass bead has a beautiful pattern that looks like a flower or the universe. I'm selling it to declutter. The colors are blue and red. The glass type is called "Pyrex glass" or "Borosilicate glass," and it is a heat-resistant material used in kitchenware and other products. It is highly transparent, beautiful, and lightweight, making it ideal for accessories. The glass is created one by one from transparent glass tubes and rods in the flame of an oxygen burner, with captivating patterns and hundreds of colors, making each piece a one-of-a-kind work of art. Item: Single-strand necklace Motif/Shape: Flower/Plant, Star/Moon/Universe/Cloud The cord length is 64cm. You can also enjoy it by changing the chain to a choker or changing the atmosphere.
