In ancient times red spinel was confused for ruby and pyrope, except perhaps in different hardness. One of its oldest names is "balas ruby" in the name of the historic district of Badakhshan (part of present Afghanistan and Tajikistan), where for centuries this gem was known and mined. Another historical name is "lal" (from the Persian name for Badakhshan) used in the old Russian manuscripts.

"The Ruby of..."

In the former Burma (now Myanmar), where the noble spinel is mined traditionally along with the ruby since 1587 it was considered a separate gem type. In the Europe however the delusion continues until the beginning of the XIX century. Because of this many historical spinels have the name "ruby of ...".

First on the list is "The ruby ​​of the Black Prince" - red spinel irregularly shaped and presumably weighting 140-170 carats. Currently it is a part of the British regalia. It is installed on the royal crown in cross ornament just above the diamond "Cullinan II". The stone is named by the nickname of Edward of Woodstock, Prince of Wales, who received it most likely in 1366 as part of the prize for military assistance given to Spain.

The names of some of its owners are engraved on the stone. Currently 'Timur ruby' is owned by the British royal family. It was presented to Queen Victoria in 1851 by the East India Company. Two years later the jewelry company "Garrard" built it in a necklace along with 3 more spinels and few diamonds.
