U+2666 Black Diamond Suit

U+2666 was added in Unicode version 1.1 in 1993. It belongs to the block U+2600 to U+26FF Miscellaneous Symbols in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Symbol and is commonly used, that is, in no specific script.

The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is not mirrored. The word that U+2666 forms with similar adjacent characters prevents a line break inside it.

The CLDR project calls this character “diamond suit” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: card, diamond, game, suit.

This character is designated as an emoji. It will be rendered as monochrome character on conforming platforms. To enable colorful emoji display, you can combine it with Variation Selector-16: ♦️ See the Emojipedia for more details on this character’s emoji properties.

The Wikipedia has the following information about this codepoint:

Diamonds () (French: Carreau) is one of the four playing card suits in the standard French-suited playing cards. Diamonds along with the other French suits were invented in around 1480. It is the only French suit to not have been adapted from the German deck, taking the place of the suit of Bells. There was one early French pack that used crescents instead of diamonds, which may explain this anomaly. Rough coloring techniques on the red stripe on the German bells may have caused the circles to appear as irregularly shaped dots, and French cardmakers may have decided to drop the details and straighten out the sides.
