A neat old time Russian classic specimen with greenish crystals of grossular measuring to 0.5 cm are in size across the top of matrix with sharp pseudomorphs of what is known by the old name of achtaragdite. I don't know that if anybody has worked out exactly what the strange pseudomorph specimens are. The specimen comes with an antique label as shown at the end of the video. The specimen dates to the very early 20th century.
