This is slightly off the topic of the thread, but I have a question
someone may be able to answer for me.
I have a long, old string of tortoise shell beads, about 10 mm in
diameter. I wore them often. They were extremely beautiful, with the
characteristic variety of color. They had a lovely glow, and when
you looked into them, you felt you were looking below the surface.
They needed to be restrung, and I took them to a local bead shop who
promised to do a good job. (They didn’t). When I got them back they
were extremely dull, no glow, no depth of view, boring. I infer
that these idiots washed them in ammonia and strong detergent (although
I had stressed that they were real tortoise shell and rather
delicate.) Looking back, I think they had no idea that tortoise
shell is rare, and probably failed to notice their subtle beauty. I
was so upset I didn’t return to the shop for years. Does anyone know
how I should treat them to try to get back some semblance of their
former beauty? Beeswax, anything??
