This bangle is very similar to the Libertas bangle but is double-layered. It is sterling silver with 38 silicone spines arranged in a "V" pattern from the central rim. This one feels more chaotic than the other bracelet even though it is not so different.
This piece reminds me a lot of a crown of thorns sea star.
The measurements are about the same as the other bangle: 6" across from tip to tip with an inner diameter of about 2.75".
