Diamonds are Forever?

Since I wrote about the crematory urn and its return to the man who threw it into the ocean, it made me revisit my wishes to be turned into a diamond after I die. Do I have the courage to actually have my family do it? I need to put it in my will. Both my hubby and son have heard me talk about it. Not that I want anyone to wear me as jewelry. I just want to be put in a little glass case, like the heart shaped one I have of my auntie's who passed away a year and a half ago, and be set on a window sill somewhere. My little diamond, probably far from perfect, would sit soaking up the sun, like a satisfied cat watching the world go by.
I don't think I have an aversion to having a grave site. I had just heard about the ashes to diamond technique and it struck me as unique and interesting. I actually think cemeteries make a nice greenbelt in our crowded cities. I know where my parents, aunts, uncles, cousins and grandparents are buried could be like a serious kind of park where my family members and I could go and spend the day stopping at all our departed ones, spending time pondering their lives. We could bring our lunches and make a sincere effort at connecting to the past. Though I have considered doing it, I never have. We just make brief stops here and there when there is a funeral and we bid farewell to another family member or friend.
I hear now that some of your ashes can be turned into an orb. Not like the Orb in the Woody Allen film, Sleeper. But an orb as in gazing globe. I would be afraid it would break in an earthquake. Of course a diamond could be lost or sucked up by a vacuum cleaner. It's still an intriguing thought.
