The Hebrew that is translated into a wide and often differing variety of gemstones on Aaron’s breastpiece in English and other translations, was translated with a focus on their colors in a West African language:

Row One: a red stone, a stone the color of the yellow fruit inside the pod of the African locust bean (parkia biglobosa ), and a blue colored stone mixed with the color of fresh growth on trees (green)

Row Two: deep red stone, a blue colored stone, diamond

Row Three: a stone the color of an orange, a stone with many colored stripes, a stone the color of a local purple fruit

Row Four: a stone of deep green color, a stone with splotches of color, and a green stone.
