Once I was asked to make a set of my favorite "Rainbow snails" (www.livemaster.ru/item/146386-ukrasheniya-sergi-latunnye-vitrazhnye), but in other colors. A girl friend wanted to keep the benefits of the shape, material, favorite design, but it was all in other colors matching to the dress. Needed green, blue, brown. And there were "Other snails". I've done over the last years, several sets. They differ from each other in color, design pendants are also different. On the pictures there are a few examples.
Earrings are very lightweight for its size when compared, say, with stained glass earrings with glass inserts. Them comfortable to wear, they are quite resistant to fall, over time, plastics have small cracks, which, however, do not affect the strength, add more light. If you do not put earrings in mechanical breakdown, their "service life is not limited".
If you want to order a set of earrings, pendant, make, please order, I will need at least a week to do for you pendant.
