Luna Mother of Pearl Pendant Necklace


Availability: In stock

The Luna pendant necklace is a stacking favourite and presents a gleaming mother of pearl slice set in 18 carat gold-plated sterling silver and surrounded by white sapphires. This gold necklace projects iridescent flashes of colour and is inspired by images of the early morning moon and the hypnotic waves it conducts. Its gemstone pendant is softly scalloped in spirit of rhythmically lapping tides.

  • Mother of pearl is the inner lining material of the pearl shell
  • Add a free engraving to the back of the pendant to personalise
  • Includes the Astley Clarke star-set white sapphire tag
  • Styled here with the Mother of Pearl Locket and White Pearl Choker
  • Also available as part of a necklace stack
  • All of our gemstones are cut and polished by hand

"Beautifully discrete, while still looking dazzling."

The story behind the stone…

Amongst one of the first materials used by ancient craftsmen for decorative purposes, mother of pearl has been used for millennia for utensils and ornamentation. Fine mother of pearl artefacts have been found in Turkey dating back to the early Bronze Age, and in the Egyptian pyramids from around 4,500BC.

I bought this for my mother’s 50th and she loved it! Wonderful quality and incredibly beautiful.

My daughter gave me Lace Agate Luna earrings in rose gold as a gift, and I was impressed with their delicate beauty. As a result, I wanted to purchase the matching necklace which is just as lovely. Though I had never heard of Astley Clarke jewellery before, I will be buying more. The designs are unique, eye-catching, and made with quality materials. Furthermore, Astley Clarke's speed of delivery and excellent customer service provide hassle-free shopping online.
