This is a hand crafted typical Indian/Sri Lankan style Bangle or Statement Bracelet.
A bangle is typically a rigid bracelet that has no clasp or opening. Instead, you slide the bracelet over your hand and onto your wrist. Because of this, bangles are generally loose and tend to move around.
When wearing a thin bracelet, people tend to layer them, either with similar bracelets or a number of differently styled ones. However, you can also opt to wear a single, large bangle which would work like a statement bracelet.
Bangles are very popular in Asian countries like India or Sri Lanka and are generally seen as a staple part of a person’s outfit.
