bought this to wear to a gala and it was absolutely the right choice. the square onyx chain has such a dramatic and elegant presence under evening lighting. so many people asked about it

the square onyx stone chain is the most original necklace i own. nothing in my collection looks remotely like it and the quality is genuinely impressive. the black and gold contrast is just perfect
Alicia M.
really stunning necklace and the square onyx is so striking against the gold. the quality is excellent. the 39cm length runs a bit snug on my neck and i use the extender almost always but it works great at that length. the design is just beautiful and i wear it all the time
Serena R.
gorgeous necklace and the black onyx and gold combination is really striking. the quality is great and the stones are well set. i wish the chain links between the onyx were slightly longer but the current proportions still look elegant and refined
Crystal H.
really love this necklace. the square onyx design is so unique and the gold is beautiful and warm. the clasp is a tiny bit fiddly but i got used to it quickly. the necklace itself is bold and gorgeous and i wear it all the time
Adriana E.
the square onyx chain is genuinely beautiful and the black and gold contrast is so striking. i expected the onyx stones to be slightly larger from the photos but the actual size is still very elegant and impactful. the quality is excellent overall
Shanice G.
beautiful necklace and the square onyx stones are so well set. the gold is warm and rich. i found one of the onyx stones was very slightly less perfectly aligned than the others but honestly you'd never notice when wearing it. really happy with this purchase
Ebony J.
love the square onyx chain concept and the execution is really good. the gold is beautiful and the onyx is deeply black and striking. i just wish the extender were a touch longer. it works at the current length but more flexibility would be great. still a gorgeous piece
Bianca T.
the necklace design is really pretty and the square onyx concept is cool. mine arrived and the 39cm base length is much shorter than i expected. it sits very high and tight even for a choker. the extender helps somewhat but it's still snugger than i like. the gold and onyx quality are both good though
Camille N.
the square onyx chain is beautiful in photos and the design is genuinely striking. in person the onyx stones were smaller than i imagined from the product images. the gold is nice and the quality is ok. a decent piece but i was expecting something more substantial and dramatic
Destiny O.
the design is really nice and i love the square onyx and gold combination. one of the onyx stones on mine had a small surface chip that was visible up close. the necklace still looks fine from a normal distance and the overall construction is decent. the concept is beautiful and the gold tone is warm and good
