Traditionally, cremated remains were buried in cemeteries; however, due to modern funeral reform, options have expanded significantly. Remains may still be buried in a cemetery or placed in a columbarium for safekeeping; alternatively, they can be interred via tree burial, flower burial, or sea burial.
Beyond these methods, cremated remains can also be transformed into items such as diamonds. My specific inquiry is this: using cremated remains-or extracts derived from them-as raw materials, what other types of keepsakes or jewelry can be created? I am interested in options that possess commemorative significance while also being economical and environmentally friendly. For instance, aside from crafting ceramic (bone china) keepsakes or diamonds from ashes, what other possibilities exist?
