Frequently Asked Questions.

Every Luck Xiour diamond arrives with an independent grading report from a recognised gemmological laboratory. The report states the cut, colour, clarity, and carat weight of the stone, along with its measurements and any treatments. We do not set a diamond that cannot be documented this way.

Our jewellery is crafted through a combination of in-house craftsmanship and trusted partners in the USA and India, often made to our own designs and specifications. Every piece is carefully quality-checked to meet Luck Xiour’s standards.

Clean diamond jewellery with warm water, a drop of mild dish soap, and a soft toothbrush, then dry with a lint-free cloth. Remove pieces before swimming, exercise, or applying lotion. Store each item separately in a soft pouch, and have settings checked once a year.

Yes. We source only from suppliers who comply with the Kimberley Process and can trace their stones through a documented chain of custody. Metals are refined from recycled and responsibly mined sources. Sourcing documentation is available on request for any piece we sell.

Luck Xiour sells exclusively through authorised marketplace partners rather than a direct checkout. Our Where to Buy page lists each official storefront, including Etsy, Amazon, Shopify, Walmart Marketplace, eBay, TikTok Shop, Facebook Shop, and Instagram Shop, with launch status for each.

Our pieces are made in 14k and 18k yellow gold, 14k and 18k white gold, and platinum. White gold is finished with rhodium plating for a bright, even surface. Metal type is stated for every design so you can match new pieces to what you already wear.

Start with cut, which governs how much light a diamond returns, then balance colour, clarity, and carat to your preference. Our Diamond Guide explains the 4Cs in plain language and shows the grading ranges Luck Xiour works within for each collection.

Yes. The Wedding Collection includes engagement rings, eternity bands, and matching bridal companions, all set with certified diamonds. Pieces are produced in limited editions, so availability varies by marketplace partner and by season.
