Vintage Black Sea Sediment Jasper Snuff Bottle

This beautiful and mysterious stone snuff bottle may not be a black jasper or is it a snowflake obsidian? My stone identifier keeps giving me different identifications.  Nevertheless, it is a bottle of significant size and appearance.  The flattened rectangular body that slightly tapers to a raised oval foot has the most intriguing purple streaks that are fused to the black stone.  The sloping rounded shoulders extends upwards towards a straight round neck with a flat top and a small opening for the spoon.  The snuff bottle cap is a grey/green agate with a cork stopper and bone spoon.
