These are Triangle Labradorite studs with White Topaz Halo set in Gold Plated Sterling Silver, made by hand in Chicago, IL, by Stella Blue Design.
Labradorite is named after the Labrador Peninsula in Canada that hosts this unique kind of feldspar stone. When light hits the hard crystalline mineral, it displays spectral colors that ignite from the inside. This phenomenon is called “labradorescence”. Its colors vary from off-white to black, blue to green, and sometimes orange to red. And the softer blue shades to subtle green are what’s usually made into precious jewelries.
Of all the mystic and magic about this stone, of the most impressive is that it’s said to dispel anxiety and depression.
