This Family Tree Glass original design is inspired by that special bond between a mother and her precious child, each one sculpted in a different color symbolizing their individuality, & spiraling together in unity. A wonderful heirloom keepsake gift for any mother! Each one is unique, handblown individually using borosilicate (Pyrex) glass, sculpted in the flame, then kiln-annealed to ensure durability. Appx. 1.", comes lovingly wrapped in a gift box with a free adjustable cotton necklace cord.
