The Amethyst-class corvettes were a class of the last wooden warships to be built for the British Royal Navy; each was built at a Royal Dockyard.

She served alongside HMS Shah in the action against the Peruvian warship Huascar on 29th May 1877.

Unlike earlier wooden corvettes in the Navy, they had clipper bows (like the earlier Amazon Class sloops), while the last two had frigate sterns.

All were initially ship-rigged (except for Encounter, which was barque-rigged), but after their first commission the Modeste, Diamond and Sapphire (but not Amethyst) were re-rigged as barques.

They were completed with fourteen 64-pdr guns, of which twelve were truck-mounted on the broadsides and two were on rotating slides as bow and stern chasers.
