Jade is really two different minerals. One is called “jadeite,” which is about as hard as quartz and can be found in a variety of colors including lavender, pink and emerald green; and the other is called “nephrite,” which is a tad softer than quartz and is found in shades of either white or green.
Agate is a microcrystalline variety of silica that comes in a variety of different types and colors. A piece of jade this size (approximately one foot long) would be very unusual and the color and striations we see in the photo looks more like agate than jade; but to be sure which of these substances it is, B. L. P. will have to have it tested by a gemologist or mineralogist.
The real problem we have is that the quality of the work does not seem to be all that phenomenal. The piece is certainly very attractive, but we think it is what we would call “tourist” quality — meaning that it was never intended to be an art object, but was a souvenir of a trip to the Orient or imported into Germany for decorative purposes.
Let us say that whether this piece is jade or agate (and we lean heavily toward agate), there is a market for this item. If it is agate we think this piece from the first quarter of the 20th century would sell at auction for between $800 and $1,200 (or perhaps a bit more) and should be insured for twice that amount.
