Damaged Amber and MOP necklaces

I’m presuming it’s damage not deliberate anyway. Looks like someone left a ballpoint pen in a bag of jewellery
The toffee coloured bead necklace is long-77cm long doubled. I think they are amber beads ( pressed?) as they fluoresce nicely but the white beads appear to have ink on them. Its on the inside of every bead so I thought maybe ink had wicked it’s way along the thread but the thread is clean . There is another what I think is mother of pearl necklace too again with ink on it. Craft project gone wrong?
Any idea what the white beads may be ( worth saving or not?)
I’ll give them a scrub but I don’t hold out much hope as it looks like it’s soaked in. The amber ones are fine.
Would you unstring the white/ amber ones and try (*whispers*) bleaching the white? .Then restring?. Or ditch the white ones and find some new ones to go with the amber? The MOP is probably beyond changing but I’ll give them a bath and see.
Thanks

 

The purple might be there deliberately, to mimic shell. The other looks like dyed shell for sure.

 

Maybe. I thought that to begin with but then thought it was too much of a coincidence that both totally different necklaces from the same shop had the same dye?. I really don’t know!

 

Never mind the inky ones, those butterscotch beads will make you some nice money.

 

Do you think?. They look rather edible.....nom nom.....there are 37 of them,would you sell as is or loose?

Edit-
OMG, they go for lots of money on eBay!. I just had a look

 

Oh yes. Eight times the price of gold, gramme for gramme.

 

I agree, pressed amber, but mixed with other 'stuff'. They probably won't float in salt water, due to the high compression of the amber, and the additional substance, although some do.

They were made in the late 19th-early 20th century in Germany. I suspect that was on the Amber Coast in Königsberg, East Prussia, which is now Russian and named Kaliningrad.
Most amber in East Prussia isn't collected along the seashore, but it is mined just inland from the coast. It has been a real industry for a long time, and I imagine they could manufacture pressed beads on an industrial scale.

Most of these beads were traded to the Middle East (Yemen!) and North Africa, but they were used in fashionable European necklaces as well.
They are very collectible, especially among ethnic jewellery collectors.

 

I went digging through my
‘I don’t know what they are, bead hoard’
and these get my curiosity.
Some look like pressed amber but don’t fluoresce or have any seams.
Some look like pressed amber and fluoresce orange ( is that right for amber?)
Some swirly ones are clearly plastic with seams. Strung on linen thread with a plastic screw clasp. Don’t think they have much age to them but I’m wondering about the orange under UV?. The arrowed ones fluoresce.

 

Thankyou for all this information. Really useful. What tells you they are turn of the century?. Is it the amber beads themselves or the rest of the necklace?

 

These are easy - side seams = plastic. Those darker ones might be something else, but I wouldn't put money on it.

 

The wear and patina on the beads (lovely) and the production period.

Although amber fluorescence is usually in the pink-lilac to green-blue range, some amber can fluoresce yellowish orange.
The beads with the arrows don't look like amber composite to me, but other materials fluoresce as well.
