Hi Gav
the Ottomans, or peoples of Ottoman culture had to love especially the precious materials, like;
gold, silver, ivory etc. and semi-precious to precious stones
not rare to find it on the hilt and scabbard's daggers, and even swords,
what should be the brake, was certainly the price to pay ...
like ... every where, at any time
the Janissaries, and more specially the Mamelukes
were to be of great "
coquet"
(French word to said; love to dress handsome)

ps/ the blade need some elbow oil and the leather of the scabbard some wax 
and it will be a very nice "ya" ... I like it
