Kroma has been making decorative glass products for many years. We specialize by using Dichroic glass exclusively. It's mostly been our pleasure The Dichroic Process Dichroic coatings are produced on a variety of glass materials. Originally developed as interference filters in scientific measuring and correction applications, they are a product of the technology called "thin film physics". The coatings are quite thin, about 700 angstroms thick, and are generally constructed of silicon and titanium oxides evenly shuffled into multiple layers. These layers are applied by vacuum deposition and cause the glass to become a partial mirror by allowing only a select narrow band of light to transmit; other rays are rejected through reflection and absorption. As the light rays transmit through the glass at a right angle they are less effected by refraction than when passing at an extreme off axis angle where they have to travel a greater distance through the coated material. This greater distance causes a shift of color and when dichroic glass is viewed at even slightly different angles, you will see differing colors. *** Nine New Designer Pendants, Rings, Earrings & Necklaces *** *** Click On Thumb below For Larger Picture *** Parabola Dichroic Pendant Kroma Jewelry Designers...unique Parabola Dichroic Pendant, set in sterling silver...approximately 1.40"w x 1.50"h...18.0", 92.5 fine silver chain included. $ 175.00 Gemstone Pendant Kroma Jewelry Designers...exquisite gemstone pendant with iolite and amethyst, set in sterling silver...approximately .58"w x 1.40"h...15.0", 92.5 fine silver chain included. $ 185.00 Seven Gemstone Silver Collar Pendant Kroma Jewelry Designers...exquisite seven gemstone pendant, set in 92.5 fine sterling silver on 16" omega collar chain...gemstones measure approximately 2.10" wide across. $ 450.00 Seven Stone Snake Chain Necklace Kroma Jewelry Designers...exquisite seven gemstone pendant, set in 92.5 fine sterling silver on 18.5" snake chain...gemstones measure approximately 6.0" across. $ 295.00 Textured Dangle Earrings Kroma Jewelry Designers...fashion inspired Textured Dangle Glass Earrings set in sterling silver...approximately .70"w x .70"h. $ 250.00 Parabola Dichroic Glass Earrings Kroma Jewelry Designers...fashion inspired Parabola Dichroic Glass Earrings set in sterling silver...approximately .92"w x .78"h. $ 150.00 Three Bar Glass Ring Kroma Jewelry Designers...fashion inspired Three Bar Ring set in sterling silver...approximately 1.0"w x .72"h...size six. $ 225.00 Rectangular Dichroic Ring Kroma Jewelry Designers...unique rectangular dichroic ring, set in sterling silver...approximately .90"w x .25"h...size 8.25. $ 110.00
