Vintage necklace with gemstone "Regalite in light authentic blue-silver"

This beautiful vintage necklace consists of a gemstone cabochon, a regalite in light blue-silver, which I have integrated into a simple but noble setting.
The stone has the dimensions 25 x 18 mm. authentic Each stone looks slightly different in its pattern.
The chain has a circumference of 50 cm and is closed with a carabiner.
In my assortment I also offer the necklace with other gemstones.
Gift!
