Dichroic jewelry is formed by heating combinations of glass in a kiln, under extreme temperature, which creates an extravagant piece that can never be exactly replicated. The jewelry absorbs some light, reflects other wavelengths and changes or "shimmers" when turned at different angles. Photos simply don't do it justice, you have to see it to believe it! You can rest assured that your selection will truly be unique and join the quickly growing number of women (and men) wearing this new trend in fashion jewelry.
