Help Needed to Identify This Divided Glass Decorative Dish

This was my Grandmother's and I cannot seem to figure out what it is. It is made of glass and decorated with beautiful silver colored flowers. It is an odd shape and is divided by a heavy piece of glass in the center. It is lined with the same silver color as the flowers. It measures about 7" from one point to the other and about 6" at the widest point across. I cannot find any maker's marks on it. It is heavy and weighs almost 14 oz.
Thanks in advance for any info!
