This is for a beautiful Lalique "ECLAT" collection pendant or enhancer in yellow gold plated mounting with a lilac purple Lalique crystal.

The retail price was about $350 but it is a retired collection and not available in store.  Actually, Lalique does not sell gold plated jewelry any more which makes this pendant even more collectible.
The pendant/enhancer measures about 1.75 inches (4.5 cm) tall and 1 cm wide.

It is on a 33 inches purple color necklace cord.   

Marking is "LALIQUE" and its emblem on the back side.
The pendant necklace is brand new and never been worn as shown!
Since this is an enhancer, you can wear this pendant on a gold chain, beaded necklace or pearl necklace also.  You can unlock the clasp or snap close the clasp of the pendant easily.

Here is the description of the "ECLAT" collection:
