2 Vintage Tourmaline (?) Necklaces Multicolored Pink Green Watermelon Colors

2 Vintage Necklaces. I was told these were Tourmaline Chips when I purchased these a very long time ago but I never had them appraised so I can’t guarantee if they are indeed tourmaline or not. They are very pretty either way. Multicolored. Colors include Pinks and Greens and I believe you can call them watermelon colors when together but I could be incorrect. You can pull them over your head and they don’t have any clasps. I used to wear these a lot at work since they went with anything! I find that I don’t wear them enough anymore so I’m selling. Measurements are rough approximate measurements and colors may be off because of lighting. These have age and I wore them a lot so they have a lot of irregularities and imperfections. Please zoom in on pictures. I feel the imperfections add to their character. Wear them together or wear one and give one to a friend or daughter/ mom.
