This forever blooming Calla Lily is about 2.5 niches in size. I created murrine to mimic the fresh bloom captured in time. I surround the bloom with a circular pattern of glass murrine and shape the sphere into a perfect form with a graphite mold.
You can watch a video of a similar marble being made:
