Lovely glass paperweight by Mats Jonasson of Sweden, I believe this would originally have had a label describing it as "full lead". The weight is signed to the base with the initials NJ / Sweden and the number 9177. There are scuff marks to the base where the weight will have been moved around for cleaning. The weight is approximately 75 mm tall x 75 mm wide. Please see photos for assessment / appraisal. Any given dimensions are approximate.
