When you purchase from The Diamond Channel, you're not just buying jewelry — you're investing in a piece that's backed by our complete, unconditional guarantee. We stand behind every piece we create, forever.
Lifetime Craftsmanship Guarantee
Every piece we make is built to last a lifetime — and we guarantee it. If any piece ever breaks, bends, or shows a manufacturing defect, we will repair or replace it at no cost to you. This guarantee never expires.
Free Lifetime Resizing
Fingers change over time. If your ring no longer fits, bring it in (or ship it to us) and we'll resize it for free — as many times as you need, for the life of the ring. No fees, no fine print.
30-Day Returns — No Questions Asked
Not in love with your purchase? Return it within 30 days for a full refund. No restocking fees, no hassle. We want you to be completely happy with your jewelry — or your money back.
Free Shipping Both Ways
We cover shipping on every order — and on every return. You'll never pay a delivery fee when buying from us, and if you need to send something back, we'll provide a prepaid shipping label.
Certified Quality — Always
Every diamond we sell is independently certified by IGI or GIA — the world's most trusted gemological laboratories. You'll receive your certificate with every purchase, so you always know exactly what you're getting.
Expert Repair Service
Our NYC craftsmen are available for repairs, cleaning, and restoration on any piece purchased from us. Prong re-tipping, stone tightening, rhodium plating — we handle it all, often at no charge for covered repairs.
