These Jobs Tears have been grown in my garden and included with old blue glass beads to add some color. These botanical seeds are made into jewelry, rattles, sculpture and even rosaries. I grow and sell the seed and make jewelry with them. I string them on tiger tail for long lasting strength. The blue glass beads I used with my jobs tears on this necklace are 50 years old. The seeds will start to look like stone as they pick up your skin oils.
