Something that always interests me is jewelry combinations and how each individual puts together their jewelry for the day.  Ashley Olsen never ceases to amaze and always comes up with some great mixtures.  From what can be seen, she is wearing her Cartier watch, a large black stone ring, and possibly a crowned diamond heart ring.  Not sure what the other rings are! Take a look at some similar choices if you are wanting to achieve this same jeweled look.

A crowned heart is a known symbol of love and loyalty. This one is priced at $5500 from Fay Cullen. It is a 1 carat heart shaped diamond set in platinum. A definite necessity in anyone's ring collection.

Although Ashley's black stone ring is larger and pear-shaped, this one still gives a similar effect. Designed by Pippa Small, the black stone is actually a Labradorite. I think Ashley's ring is an onyx. The Labradorite is set in 22k yellow gold, found on TWIST for $1685.

This is the exact watch Ashley has and was featured in her book Influence. Found the match at AuthenticWatches.com, not sure how reputable this company is, although they have high ratings under Bizrate. It is called the Cartier Pasha Seatimer Men's Steel Watch and sells for $4975 on their website.
