This two-part man’s buckle, held together by a central clasp, is of high-grade silver with remnants of gilding (gold plating).
Each of the two parts is of Islamic-inspired boteh-form and has crenulated edges, a scrolling rococo-like border and a central panel depicting an Orthodox Christian basilica.
The reverse is fitted with silver bands to allow the buckle to be fixed to a cloth belt.
A related example is illustrated in Kaplani (1997, p. 142).
The form of buckles such as this originated in Ottoman Turkey.
The example here is in fine condition.
