- earcnanstan, eorcanstan, eorclanstan
Compound of eorcnan "special, noble"(?) (more at erchan) and stan "stone". Parallels Old Norse jarknasteinn, which is generally regarded as a loan from Old English. Translates margarita in 9th century biblical glosses but is used generically as "precious stone, gem" in Beowulf (line 1208) and The Ruin (v. 36).
- precious stone, pearl
