Ruby

“Coral and quartz are unworthy of mention; the price of wisdom is beyond rubies.”

“There is an abundance of gold and rubies, but lips of knowledge are a rare treasure.”

“A wife of noble character, who can find? She is far more precious than rubies.”

“Her dignitaries were brighter than snow, whiter than milk; their bodies were more ruddy than rubies, their appearance like sapphires.”
