What is this mark? Is it silver mark?

Hello
I got this pendant, and there is 3 marks as on photos , nothing else.
Could you help me with this? I have mo idea, never seen before.






It is 800 in Arabic numerals. This probably signifies the 800/1000 silver standard but without any other marks it is difficult to say for sure.

Thanks a million.
Wow, I would never figure it out myself.
No other marks unfortunately.

that is no meaning, maybe just only a general logo

See the answer above , its arabic silver mark
