What Do the GIA Gem Clarity Grading Codes Mean? Gem Society
You might encounter stones with clarity grades of Dcl on the market. Dcl (d#233;class#233;) means a stone doesnt have the transparency or durability for faceting. However, Dcl stones may be used for cabochons, beads, or carvings if theyre structurally intact. Diamonds (and only diamonds) can have clarity grades of F and IF.
