Solana bangle is made from recycled 925 sterling silver, goldplated in 18k. The cuff is one size but can be adjusted by softly stretching it open. Please note that the stone is centered, so you have to be very careful when putting it on and off. It measures 6cm in diameter. It's adorned with an oval citrine, which is a gemstone of abundance and manifestation. It has a light yellow color and should bring you good energy, like the sun.
