This ring is amazing for the price.  It doesn't turn my finger green, and the sizing is great.  It's just a little bling that isn't too flashy.  I wear it as a thumb ring.  I think it's really pretty, and very sparkly.

UPDATE #2:  About 2 years since I bought the ring, it started to tarnish.  The silver began coming off and (apparently) I am allergic to whatever metal is underneath.

However, I am still very pleased with my purchase.  For $20, two years of heavy use is a great deal!  Highly recommended for anyone who needs a ring to use regularly for a period of time (i.e. pregnancy, weight gain, special occasion).  This was a great purchase.
