I love black spinel, really sparkly
And it seems the lower the lighting, the better the sparkle.
I bought a bracelet at Sam's Club last year.
NCH152 is similar but mine doesn't have the magnetic clasp.
It has a kind of slide clasp, pretty much invisible when fastened
I have no problem getting it on & off and I love wearing it.
During the holidays at the end of the year, my Sam's Club brings in really nice jewelry at a great price.
