Turquoise

Could anyone tell me about this Stone and where it might be from it was in a collection of stuff left to me, 52mm square and approx 15mm thick two holes running through it .Came with some Tibetan and Chinese artifacts that’s all I know.

 

It could be Hubei turquoise,but it looks like it came out of a Chinese factory.

 

Hi thanks for looking it doesn’t sit exactly flat as it’s not perfectly square looks hand carved don’t know about Chinese factory it was purchased in a lot from Sotheby’s or Charterhouse School Museum a number of years ago.

 

I also think I might have some other Turquoise though I’m not familiar with semi precious stones .

 

One on the far left looks to be the oldest with three holes drilled through which I imagine is harder than one or two holes without breaking the stone.The far right pendant is a puzzle haven’t discovered the meaning on the front of it as two are eternal knots and another symbol I’m searching for is on the black stone.If anyone has any info about these piecesI would be grateful I have only found one endless knot pendant with beads.
