It's tribal bage of the ansien Crimean Herai dynasty that ruled the Crimean Khanate.
Now it is used by the Crimean Tatars as a national symbol.
The founder of the Crimean Khanate Haji I Gerai was the first person who use this sign.
The name tarak-tamga means in translation from the Crimean Tatar "sign - crest" (Crimean Tatar. Taraq - comb, comb; tamğa - sign, stigma).
The plot of the bage is an interpretation of the image from the famous portal of the Khan's palace "Demir-Kapa" in Bakhchisarai
