This hackmanite necklace consists of multicolored, smoothly polished hackmanite beads of selected quality. The hackmanite used is a natural gemstone and is rarely available in this variety of colors and purity. The beads are natural, untreated and have an even, high-quality finish.
Hackmanite is known for its so-called tenebrescence effect: the color can change visibly when exposed to sunlight or different light (daylight, artificial light). In a dark environment or under ultraviolet light, the stone returns to its original violet color. This color change is a natural, repeatable effect of the gemstone and makes every wear a special experience.
The pearls have a diameter of approx. 5.9 mm to 5.1 mm and are carefully matched to each other. The total weight of the necklace, including the clasp and silver beads, is approx. 97 ct. This necklace is a unique one-off piece and cannot be reproduced.
Please note:
In order to preserve the natural color effect of the hackmanite in the long term, the necklace should not be exposed to direct, strong sunlight or heat for long periods of time.
