Susan, I ordered the sterling with no diamonique.
Pros: I love the texture and color -- they go with all my other JR pieces. They are substantial and weighty. Very wearable for every day.
Cons: They are a bit jangly and noisy, noticeably so. And I thought they were pricey.
Draw: I don't like that they are hollowed out inside and wish they were more finished; it looks funny to me. But I'd rather have that than lightweight hollow bracelets that could dent. And solid bangles would be very heavy and very costly.
I'll probably keep them because they are just good basic JR, good when you don't want bling but want substance, and good as a foundation layered with other cuffs and bangles. If they were a little less expensive they'd be a no-brainer for me. It's the price that makes me hem and haw. But I think I'll be reaching for them often and I also think that if I send them back I'll be kicking myself later.
Hope that's helpful.
