Kolt
Kolt or kolty was a part of a female headgear, hanging on a ryasna at both temples as a sign of family's wealth, common in 11th-13th centuries in Old Rus'. It comprised a pair of metal pieces, joined to form a hollow medallion or star that, presumably, contained a piece of cloth, impregnated with fragrances. Origin 
The origin of the word “kolt” is obscure. As a term, it was introduced in the late 19th century in the course of ethnographic surveys. According to a version it derived from the  meaning (earrings), also in West-Ukrainian dialects “колток”. In a Novgorod dialect the word “колтки” means pendants of earrings, it was also mentioned in birch bark document No. 644, found in Novgorod, dating back to Novgorod Republic. References
