Birthstone and Anniversary Gems Combined for Gift

Dear Dr. Dave and Dr. Dee,

My wife and I will be celebrating our 15th wedding anniversary in April, and her birthday is also in the same month. In the past, she has stated that she would like jewelry, but as I don't know what to get, I usually give her a gift certificate to a nice department store where she often shops. This year, however, she has told me that she wants a necklace since it's an important anniversary date. What do you think would be appropriate? I've asked her, but she says she wants me to surprise her. Any suggestions would be helpful.

Signed,

Perplexed

Dear Perplexed,

For a 15th wedding anniversary, the gem would be ruby. Since her birthday is in April, the birthstone would be diamonds. A 17-18" necklace combining both diamonds and rubies in 14K yellow gold would be lovely. There are many styles and prices, so go to a reputable jewelry store and see what's there.
