From my father in law's estate. He taught jewelry making from 1960-1980
The owner of a rock shop told me that these pieces are jade
The 6 rounded oval pieces are approx; 3/4" x 1/2" and vary from 3/16"-1/4" in height
The 6 pieces weigh; 0.5 oz or 14 grams
The 2 longer ovals are approx; 1" x 5/16" x 3/16"
I could not get a weight on the 2 pieces
I have tried to include any imperfections in the description or pictures.  Please ask any questions before bidding.
