Thank you for viewing my items from among many others. This is a handmade accessory, a resin accessory that encases natural stones in resin. The stone is crystal. I created this piece by placing crystal and aurora-colored glass inside a circle, imagining the blue sea. The glitter sparkles elegantly. Necklace chain Size: Approximately 42 + 5cm If you would like gift wrapping, a keychain, a leather cord, or a change in chain length, I will accommodate your request free of charge, so please comment (o^^o). If there are no comments, it will be sent as is. Also, if you wish to purchase multiple items, I will discount the shipping cost by 200 yen m(_ _)m Because this is a handmade item, there may be some slight imperfections, such as warping or air bubbles. The color may appear different depending on the angle of the photo. The strength and quality of the chain, etc., are not as high as commercially available products, but thank you for your understanding. No. 406
