🐳🎁Necklace: mini multicoloured pieces of semi-precious stones (mainly quartz)

Vintage from the 1990’s A conversation piece for beachcombers... and the rest of us! They are minerals purchased in the New York Natural History Museum gift shop. If you like the sea, it will likely remind you of “seaglass" or the small glass pieces worn out by the sea that you find on the beach. The said museum has an extensive collection of stones very well presented so that was a memento of my visit. The stones are, in fact, cut and polished miniature minerals with a diversity of shades. Like new. Colours include shades of purple, lilac, green, turquoise. Some white and hints of black in some minerals which are generally transparent. Hues will vary with lighting. Lenght is about 14.5 inches ( x 2). Goes over your head (No opening). It is like new. I have included a picture of some stones and their meanings in case you are interested.
