According to most descriptions of Sarah in the Bible (or Sarai as she was first known), it is usually in reference to her relationships, her shaky faith, and characteristics of her personality. Most of these are mostly in the Book of Genesis. The only physical description of her says that Sarah was a beautiful woman. This is mentioned in Genesis chapter 12, verse 11. "As he was about to enter Egypt, he said to his wife Sarai, 'I know what a beautiful woman you are,'" the passage reads (via Bible Gateway).

Sarah was so beautiful that even though she was already married to Abraham, King Abimelech had taken her as one of his wives. God did not approve and vowed his death if he did not return her to Abraham, which he eventually did.

Sarah apparently had the luck of retaining her youth despite her old age. Some Bible experts use that to explain how King Abimelich would've been attracted to her. Genesis 23 described her death at 127 years old. Some researchers have taken other descriptions of her age to mean that when she reached her centenarian years, she looked like she was in her 20s, and when she was in her 20s, she looked as though she was 7 years old, per Chabad. Art depictions of her vary, but almost all references say she still maintained her beauty.
