Oh sry ive been cracking periodically, you all must have posted while I was asleep. No, there are no stones missing some are just darker then others and its about 2 inches tall, and no its not silver.
On, further inspection I noticed one of the stones is slightly chiped I hadnt noticed because I've never worn it. Its still there and hard to see but I got it as a gift and only looked at it a few times.
