This is a special pen made from Blackwood-Dalbergia melanoxylon. This is a very special pen that looks almost black acrylic because the finish is so sharp and smooth. If you look very close you see some grain. The componets are 24 ct gold and make the finish pop. 
 
African blackwood has a mild—though distinctive—scent while being worked.
 
African blackwood is listed on CITES appendix. It’s also reported by the IUCN as being near threatened. Technically it doesn’t meet the Red List criteria of a vulnerable or endangered species, but is close to qualifying in the near future.
