CD 164 McLAUGHLIN in a very dark yellow citrine. I say yellow because most citrines have a fair amount of green tint to them. The units with less green and more of a yellow brown color are very tough to find. I have never owned one darker and with less green then this one and I have seen them sell in the close to one thousand range. This one is VVNM with tiny flaking on the very sharp edge of the inner skirt. 625.00 PP
