Diamond Bowl

2 quart clear glass bowl with no manufacturing information. There is a faint blue tint to the glass. The design feels and looks like a thumbprint within the diamond shape. The bottom is a starburst rimmed with diamonds. I am not sure of the manufacturer or if it is old enough to be considered vintage. I've had it for about 9 years, but it was used, when I bought it. No chips, cracks, breaks or rough rims, but light interior usage marks. Photos soon. I need your zip code to calculate the postage.
