GeoCUBE® necklace in dopamine shades. At COEUR DE LION, we have known for a long time what science has now confirmed: that vibrant, bright colours have a positive influence on our mood. Wearing them - so-called dopamine dressing - automatically puts you in a good mood. The sensational colour spectrum of our dopamine-look models is largely created by natural gemstones: red and blue aventurine and harmonious rose quartz. This design twins all of these with a modern sliding fastener, allowing you to wear the necklace as a choker, mid-length or long to suit your mood. For a layered look, you can also wear it with the delicate Princess Shape Mix dopamine necklace and the small Guardian gold multicoloured pastel necklace.
