5* Company

I purchased the Personalized Name Necklace With Diamond recently as a birthday gift but I needed the chain to be different. The team at Onecklace could not have been more helpful with my request. Their service and quality of product is exceptional and I will definitely be ordering again - Thanks Again x

Cute Necklace; Efficient Service

I love this necklace and the way I could customize details to create a special birthday gift. The company made and shipped the necklace within just a day or two, so I received it only 7-10 days after ordering.
