Absolutely love this pendant. This is the third one I’ve bought as a gift and the engraving is beautiful (it’s so nice to be able to choose the type of font you want too!) I also selected the gift wrap option and the wrapping was lovely!

We were pleased with the necklace which arrived in good order and very quickly. The inscription on the back was also most delicately done. In view of its small size the packaging was perhaps rather excessive, but no complaints at all about the product.

Reply from Astley Clarke

Hi Howard, thank you for your review. We have taken on board your concerns about our packaging and this is something we will take into consideration for the future. In the meantime, we hope you enjoy your new necklace. Best wishes, The AC Team.

Absolutely beautiful necklace, simple classic design that won't go out of fashion. I got the necklace personalised and it was perfectly done no flaws. The order came through in great time too.

I ordered this for my Daughter. She loved it so pretty and dainty for everyday and her name engraved on the back made it extra special. Will definitely be ordering more to make a personal stack for going out.

I could not be happier with my purchase! It's a gift for my sister's 30th birthday, I had it engraved with an initial and it came out looking amazing. The whole process, from ordering to delivery, was quick and smooth, and I am super happy with the product.
