Black Agate Crystal Necklace by Xander Kostroma – Style, Meaning & Review
AD // PR Sample
When it comes to statement jewellery, finding a piece that combines style with intention and integrity can feel like searching for a needle in a haystack. However, the Black Agate Crystal Long Length Statement Necklace by Xander Kostroma ticks all the boxes and then some. Ethically handmade and spiritually inspired, this necklace brings a bold energy to your look, alongside calming vibes to your day.
Black Agate Crystal Necklace – A Statement Piece with Meaning

This Black Agate Crystal Necklace makes a lasting first impression thanks to its striking design. Hanging on a gold tone chain of approximately 68cm in length, it features a large black agate pendant (around 5×3 cm) which matches the chain thanks to it being edged in a soft gold tone. Due to the fact that each stone is different, thanks to their natural shape and markings, no two necklaces will ever quite be the same, making each one a unique piece.
If you would like to know more about the stone, black agate is particularly known for its grounding and protective properties. It is also said to absorb negative energy as well as promote inner strength. So if you believe in the power of crystals, this could be the perfect necklace to wear when you need a little emotional boost or simply want to feel more balanced.
Handmade and Ethically Produced

Xander Kostroma is a brand that truly cares about how its pieces are made. The necklace is hand-finished, nickel-free, and created in small batches with an emphasis on sustainability and ethically sourced crystals. Each of these pendants is smoothed and polished before being edged with gold detail and being sealed, so what you’re wearing is a little work of art, not just another mass-produced accessory.
It’s that attention to detail and ethical ethos that really sets Xander Kostroma apart in the world of crystal jewellery.
An Accessory Which Is Versatile and Easy to Style
Whether you’re dressing up a simple blouse or layering it over knitwear, this long necklace is incredibly versatile. The edging of gold gives it that luxe look, while the polished crystal allows it to be styled for evening or everyday wear.
Personally, I love pairing it with a plain t-shirt and a pair of jeans and allowing the necklace to shine, after all, sometimes it really can be all about the accessories. However, it also layers beautifully with other gold jewellery for a more boho-inspired look.
The Perfect Crystal Jewellery for Gifting (or Treating Yourself)

Arriving in beautiful branded packaging, this necklace makes a gorgeous gift for any crystal or jewellery lover. At £28, it also feels like a bit of a bargain for something that is both handmade and unique. So no matter if you’re shopping for a friend, a loved one, or just fancy a little treat for yourself, this necklace feels special the moment you open the box.
