I bought three of these rings (my children and husband's birthstones) to wear on a chain.  To that purpose, they are perfect.  I wouldn't recommend them as a ring; even stacked they look ridiculous on any woman not in her pre-teens.

The emerald crystals fully encircle the ring which has a width of nickel.  The silver and craftsmanship is of good quality.  The emerald crystals are darker than pictured, but they do have a slightly blusih tint as pictured.  All in all, the ring is a good value and is great as a pendent or as a gift for a young girl.
