It depends on the type of ring you purchased:

• Ready-to-Ship Items: Yes! If you purchased a pre-made item from our "Ready to Ship" collection, you may exchange it for another item of equal or greater value within 7 days, provided it is unworn and in original condition.
• Made-to-Order Rings: Because these pieces are crafted specifically for you, we cannot offer direct exchanges. If you wish to change styles after receiving your ring, it will be treated as a return (subject to the 30% recovery fee), and a new order would need to be placed.

Don't worry—we want your ring to fit perfectly. While we cannot exchange the ring itself, we offer One Complimentary Resizing within 1 year of purchase.

• We can adjust most rings up or down by 2 sizes.
• You simply cover the insured shipping to and from our studio.

We stand behind our craftsmanship 100%. If your ring arrives with any defect or does not match the specifications of your GIA/IGI certificate, please contact us immediately. We will arrange a repair or return at no cost to you. Your "Lifetime Warranty" covers any manufacturing defects forever.

Engraved or highly customized pieces are created uniquely for your story. Because they cannot be restocked or resold to anyone else, these items are strictly final sale and cannot be returned or exchanged.

Once your return is received and inspected by our gemologist (usually within 3 business days), we will process your refund minus the 30% recovery fee and any shipping costs. You will receive an email confirmation, and funds typically appear in your account within 5–10 business days depending on your bank.

We use solid 18K gold/Platinum and lab-grown diamonds for every LUMEO piece. No plating, no vermeil—just lasting fine jewelry designed for everyday wear.

Plated or vermeil jewelry only has a thin layer of gold over a base metal. Over time, that layer wears off, exposing the metal underneath and dulling its shine.

Solid 18K gold/Platinum, on the other hand, keeps its color, value, and integrity forever—it won’t peel, fade, or tarnish, even with daily wear.

They’re identical in composition and brilliance to mined diamonds but created with a lower environmental impact.

Yes. They’re genuine diamonds made of pure carbon, optically and physically identical to mined ones.

Yes, ​GIA, HRD, and IGI all grade lab-grown diamonds and all four pieces featuring a diamond above 0.5ct come with one of these certificates.

Soak your piece in warm water with mild dish soap for 15 minutes, gently brush with a soft baby toothbrush, rinse, and pat dry with a lint-free cloth.
