This hummingbird ring is by IMOOI. The bird is red, and the background shows green and beige plants. Or you can get the version with the blue bird with blue and orange plants. So it just depends on what your favorite colors are, or what you like to wear more of that would match. I prefer the blues, but I think the red one catches the eye more easily. The ring is made of stainless steel and rubber. This is because a ring made of enamel or glass would break easily. “Designed by 2 New York artists, IMOOI products are all original works.” More.
