Description

These April diamond birthstone necklaces celebrate purity, strength, and light. The radiant stone reflects brilliance with striking clarity, elevating even the simplest moments. A true essential, designed with enduring elegance in mind.

Diamond, the birthstone of April, is a symbol of strength, purity and enduring love. Its name comes from the Greek adamas — unconquerable — and for thousands of years it has been worn to mark commitments meant to last. Whether it's carrying a personal vow or simply celebrating a birthday in April, a diamond catches light in a way no other stone does, turning even the smallest movement into something luminous.

Wear it solo above a crewneck or an open collar to let the stone take centre stage, or layer it with a longer pendant for an easy stacked look. The adjustable chain sits naturally at the collarbone and works just as well with tailoring as it does with knitwear or a plain white tee.

The Luminary Heirloom collection pairs plated stainless steel — 18K gold plating on the Yellow Gold and Rose Gold colourways and rhodium plating on White Gold — with lab-grown synthetic gemstones. Responsibly sourced and REACH, RoHS 2.0 and CA65 certified, the metal resists tarnish and keeps its colour long after other plated pieces have started to dull. It's hypoallergenic, nickel-safe and designed to be worn every day — not tucked away for occasions that never seem to come.

To keep its shine, slip it off before showering, swimming or applying perfumes and lotions, and store it flat in the pouch provided. A gentle wipe with a soft cloth after wear is usually all it needs. Full care details — including what to do if it ever needs a refresh — are in the care guide linked below.

Everything was great!

Patrycja Matyszewska-Luty

I love my new necklace! It was packed super well. The main box is made with nice material and it has an added gift bag. It's made with attention to every detail. It has an extension so you can adjust the length. The connecting rings are closed, which proves the high quality of the product. It's very stylish; you can wear it casually or elegantly.
