She is more precious than rubies - מפנינים mippeninim. The word principally means pearls, but may be taken for precious stones in general. The root is פנה panah, he looked, beheld; and as it gives the idea of the eye always being turned towards the observer, Mr. Parkhurst thinks that it means the loadstone; see the note on Job 28:18 (note), where this subject is considered at large.

Sometimes my faith is called upon to take a very unattractive road, and nothing welcomes me of fascination and delight. But here is a law of the spiritual life. The exercised faith intensifies my spiritual senses, and hidden things become manifest to my soul--hidden beauties, hidden sounds, hidden scents! …
