Aurora Borealis

Learning New Words

I'm just starting to learn the correct jewelry terms. Still unsure about crystal and stones!

Lead glass is so-called because the glass contains lead - as much a 50% of the weight of the glass is due to lead.

The presence of the lead increases the index of refraction - a high refractive index, means it bends the light more. By cutting the glass in just the right way, internal reflection from inside the shiny surfaces of the glass cause the light to reflect internally. This internal reflection results in sparkle as the glass is tilted, adding to its beauty.

This stone was created by Swarovski® in 1955 in collaboration with Christian Dior. It shimmers in every imaginable color. The effect is achieved by vapor blasting the facets of the lower part of the crystals with an invisible, micro thin metal sheet. 

 Also known as AB, the term now refers to any highly iridescent surface.

The term is most commonly used in reference to crystals, rhinestone, or synthetic stones that are iridescent.

I just listed these heavy earrings which I'm calling  Aurora Borealis for now...
