Pak Ade, Maaf sedikit menyimpang. Ngomong-ngomong soal 'diamond' saya pernah baca berita, bahwasanya telah ditemukan bahan baku terbaik untuk 'artificial diamond' yaitu.....tubuh manusia, tepatnya abu hasil pembakaran tubuh manusia. Saat ini bahkan telah dikomersilkan dan di AS ada perusahaan yang telah melakukannya. Katanya, mutu 'artificial diamond' ini hampir sebanding dengan yang asli.
Bagaimana menurut Pak Ade? Jika benar demikian, berarti bahan bakunya masih sangat berlimpah (?!)
