Dichroic glass necklaces catch the light and look different at each moment! A classy and charming gift that all the women love! Great conversation pieces, these gems are made from multiple layers of art glass with a dichroic layer in between. Dichroic glass is fired in a kiln for several hours and then cooled in a controlled environment for several more hours. The whole process takes about seven hours and the product is simply gorgeous! These make great gift items and sell for 40.00-100.00 in specialty shops.
