'Rubies' in the Bible

She is more precious than rubies, and all your desires shall not compare with her.

Her princes were purer than snow, they were whiter than milk; [their] bodies were more ruddy than rubies, sapphire their appearance.

Edom [was] trading [with] you because of the abundance of your products, [trading] with malachite, purple wool yarn and colorful weaving, and fine white fabric and black corals and rubies; [all these] they exchange for your merchandise.
