Lab-Certified Red Coral (Marjan) مرجان

In short: Marjan is one of the most imitated stones in Pakistani markets, so a lab report confirms natural coral and shows whether its colour is natural or dyed. It also flags wax or resin filling, reconstituted coral and imitations such as glass and plastic. Send any coral's link on WhatsApp and see the report before paying.

Lab-certified listings will appear here as independent reports are added to individual stones. Until then, any stone can be sent for an independent report before you pay — ask on WhatsApp.

What the lab checks on red coral

  • Natural colour or dye: spectroscopy identifies the natural pigment; dyed coral, including dyed sponge coral, is flagged.
  • Filling and coating: wax, resin or polymer used to fill pores and add shine.
  • Reconstituted coral: coral powder bonded with resin, which lacks the natural growth structure.
  • Imitations: glass, plastic and dyed bone or shell.
