Diamond design 9” bottle

It was given to me, so I have no background info. It appears to have been a liquor bottle. I will include a small cork that fits it. But the cork is not original to the bottle. Approximately 9” tall and weighs 13.7 oz without cork. “Made in Spain” is clearly visible on bottom. There is a 3” x 2” smooth space on a seam which likely held a label. It would be quite lovely on a bar. I have not thoroughly cleaned it because there are remnants of a tiny silver label on bottom which might help Identify the bottle to a collector.
