1.   A sea that was blue as sapphire the day before is turning gunmetal gray.

2.   He allowed as how I looked familiar, excepting a lot less hair turned gray, and maybe a few pounds added to the middle.

3.   White cultured pearls turned gray, pale blue sapphires turned yellowish orange, and pink kunzite turned green.

4.   No one warned them their children and grandchildren would lose their teeth, turn gray in their teens, suffer birth defects or die of cancer.
