Excellent vintage Lagos, rarely worn, sterling silver chain and framed large mother of pearl oval pendant enhancer doubled with a high domed rose cut rock crystal over top, which is called a doublet stone.

The pendant has a click open and closed bale, total length of pendant not including the bale is 32.8mm X 28.5mm wide.

Total length of chain is 17.75", adjustable shorter by hooking into any link below, each link is about 5mm wide X 7mm long, the last link is teardrop shaped, total weight of 35.7 grams.

  

This white mother of pearl doublet pendant reflects beautiful rainbow iridescent colors through it's crystal clear high dome, and my camera and lighting did not do justice.

This gorgeous piece is hallmarked in 4 places both on the chain and pendant:

Chain-At the clasp Lagos/925, on double sided embellished triangular chain ornament with an L, and between the clasp and double sided ornament is a solid oval link marked LAGOS.

The pendant itself is marked LAGOS/925 on the inside area of the bale, I have included these in the photos.
