Preta Gil’s Ashes Become Certified Lab Diamonds for Friends and Family

Overview

• Reporters and company representatives say the stones are being handed to named recipients after completion in late November.
• Carbon isolated from her ashes was converted to graphite and grown into diamonds by high‑pressure, high‑temperature synthesis in about 60 hours at up to 3,000 °C.
• Production was split: carbon isolation occurred in São Paulo, friends’ stones were finished in India, and the family diamond was made entirely in Curitiba.
• Each piece carries a laser‑engraved certification number and the honoree’s name, visible under high magnification.
• Providers cite starting prices around R$ 3,800, with recipients including friends Gominho, Duh Marinho, Jude Paulla and Carolina Dieckmann, and family members such as granddaughter Sol de Maria and mother Sandra Gadelha.
