bdellium

Concise Bible Dictionary:

The word bedolach has been interpreted to signify both a white transparent oily gum, and a white pearl. Its color is referred to in the description of the manna (Num. 11:77And the manna was as coriander seed, and the color thereof as the color of bdellium. (Numbers 11:7)), and in Genesis 2:1212And the gold of that land is good: there is bdellium and the onyx stone. (Genesis 2:12) it is mentioned with gold and onyx stones as characterizing the land of Havilah. The white pearl seems the more probable allusion, for the manna is in Exodus 16:1414And when the dew that lay was gone up, behold, upon the face of the wilderness there lay a small round thing, as small as the hoar frost on the ground. (Exodus 16:14) compared also to the hoar frost.
