Finwe - more unusual, I think, but certainly not an anomaly. There's indication in the family trees that jewel-names were used for girls, just not quite as often. For example, Pippin has a sister named Pearl and an aunt named Esmeralda, and one of Sam's daughters is named Ruby. Basically, hobbits went for very pretty names - and besides, jewels and flowers are similar in some non-financial ways; both very bright colored and used for decoration. Like the fairy-tale of the girl who whenever she spoke, a jewel or a blossom would fall out of her mouth. Obviously they're not of equal value, but they're both attractive in their own way.
