Here is a pair of nice AM.TEL.& TEL.CO. tolls, but very likely made by Hemingray. The left is what I'd call "Jade Green Milk" - Jade is basically a pretty much homogeneous color. You may be able to see some small indication of milk swirls, but the overall appearance is of a consistent translucent color.

Note that the jade in this CD 121's is a little more of a transulent color, rather than some of the more darker jade examples in the Hemingray CD 106, CD 113 and the HGCO CD 145.

On the right, is what I'd call "Milky Aqua" - Note the heavy strongly pronounced milk swirling. There are areas that are nearly regular Aqua while areas that are nearly Jade. It is this strong contrast that makes it "Milky Aqua".

In many (but not all...) cases, the Milky Aqua is by far the most desirable piece. One exception would probably be a true Jade CD 162 HGCO.

Here, the insulator on the left is perhaps $20 ... on the right perhaps $200 ... if you even get to see one...
