This item is from my own personal extensive glass collection.  This highly desirable item is a hand-blown glass heart paperweight/sculpture, specifically designed and crafted by glass artist Donna Gordon.  It is signed and dated by Donna in 2011. 
 
Hand-blown art glass utilizing fluid, layered swirls of vibrant cobalt blue and green pigments encased inside a thick, heavy layer of crystal-clear solid glass.
 
The sculpture features a stylized deep-lobed heart silhouette with a balanced organic bottom point that allows it to sit freestanding on flat surfaces.
 
Because each piece is individually sculpted at the blowpipe, the ribbon patterns and exact distribution of the blue and green glass inside vary slightly, making every single heart completely one-of-a-kind.
