The color on these anodized Titanium earrings is created by an electrolytic oxidation process. With regular wear the color will dull slightly when skin oils come into contact with the metal. You need only to gently wipe the surface with Windex and magically the brilliance of the colors comes right back!!! Be a little extra careful with the earrings as the metal can scratch, thereby losing the color. The colors that you see are kind of illusory as they result from the interference of reflected light from thin transparent oxide layers (not dyes). Ear wires are are hypo allergenic Niobium. The fringe measures approximately 1" x 2" and they dangle about 2.5" from the top of the triangle:) Enjoy!
