Interesting anomaly.
Obviously Sergei Konstantinovich is wearing early privately-comissioned 2nd class St.Saint Stanislaus order with swords made with flat black enamel and small eagles of pre-1856 type...

It is often wrongly believed that the fashion for Russian privately-comissioned orders with black enamel came to naught by the end of the 19th century.
In reality, orders with "black" enamel were manufacturing even during 1908-1917 time period (although in substantially smaller numbers).
