Absolutely. Every ring can be customized. We offer Silver (925), Gold (white/yellow/rose), and Platinum metals. We offer all diamond shapes and carat sizes. For color and clarity we work with the best grades only: D, E, F color and VS/VVS clarity. If you want to explore other grades, reach out before ordering and we can talk through the options. We also allow specific design tweaks. At Diamo, we truly believe that your ring should be how you like it. Just reach out before ordering, and we will work with you.

Yes. If you have a design in mind that's not in our collection, we can create it. Email us at concierge@diamo.co with your idea and budget, and we will provide a quote within 2 business days.

For three reasons.

We are a made-to-order shop with direct ties to manufacturing. No showrooms, no middlemen. That 30-50% savings go to you and better craft, better quality, and optimized logistics. We still save funds.

We heavily use technology to optimize every part of our operation. We refrain from unnecessary costs and deliver what people want, not what we want to sell.

We do not believe in inflated markups. Our markup is just enough to give back to the people who make your products and to help us operate and grow at a steady pace.

We accept all major credit cards, debit cards, and PayPal. Payment is processed securely through Shopify.

Not yet, but it's coming soon. For now, many customers use services like Affirm or Klarna at checkout if available.

No. The price you see at checkout includes the ring design, the diamond you select, and shipping to your US address. The only additional cost might be sales tax, depending on your state.

Absolutely not. We never have access to this information. It is the company Stripe that deals with it. Your data is completely safe.

Yes. They're physically, chemically, and optically identical to mined diamonds. The only difference is where they're created. One is made in a lab, the other is made in the ground.

Here are a couple of simple explanations: By Zack Emigh Jewelry, By a fellow Redditor

Yes. Every stone is certified by IGI (International Gemological Institute). Diamonds 1ct and above receive an IGI lab grown diamond certificate, and stones under 1ct receive an IGI jewelry certificate. All gold pieces carry a BIS hallmark, and all platinum pieces carry a PT950 purity mark. Certification is included in your purchase. GIA no longer grades lab grown diamonds, so we do not provide GIA certificates.

We recommend D, E, or F color grades for the best value and appearance. For clarity, VS1, VS2, and VVS2 offer excellent quality without paying for perfection you can't see.

We ship within the United States. If you are outside the US, write to us at concierge@diamo.co and we will see what we can do.

We offer complimentary, fully insured shipping on all US orders. All items ship fully insured

Yes. Once your ring is shipped, you'll receive a tracking number via email.

We want you to love what you ordered. If a gold or platinum piece isn't quite right, you have 14 days from delivery to return it for a full refund.

Email concierge@diamo.co and we'll send you a return code, then send the ring back to us within 7 days. It should arrive unworn and in its original condition, with the tags, packaging, and certificate. The return label is on us.

Your refund is processed within 5 to 10 business days of the piece reaching us, and your bank may take another 2 to 10 to post it.

Silver pieces are exchange-only, so they are not eligible for return unless there is a manufacturing defect, which our 1-year warranty covers. Custom, engraved, and personalized pieces follow the same rule: not returnable except for a defect.

Not quite the right fit? We can resize most designs, though a few settings cannot be altered, and we will let you know right away if yours is one of them.

Email concierge@diamo.co within 14 days of delivery for a confirmation code, then send the ring back within 7 days. Your first resize is entirely free, including the return label. Additional resizes are $100. Silver pieces are included as well.

If you would like a different size or a different style, we are glad to help. Gold and platinum pieces can be exchanged within 14 days of delivery for the same piece in another size or color, or for a higher-value piece with a top-up, and the return label is on us.

Silver pieces can be exchanged within 14 days for the same or a higher-value item, with the return label covered by you. Custom, engraved, and personalized pieces are not eligible for exchange.

To begin, email concierge@diamo.co for a code and send your piece back within 7 days.

Yes. Every piece is covered for 1 year from delivery against manufacturing defects.

A manufacturing defect means a fault in how the piece was made, such as a loose or poorly set stone, a setting or prong that fails under normal wear, a plating or finish issue, or a diamond that does not match its certificate. Normal wear and tear, scratches, accidental damage, loss, and theft are not covered.

Clean it with warm water, mild soap, and a soft brush. Avoid harsh chemicals. We recommend professional cleaning once a year.

Contact us immediately. If it's within warranty, we'll repair or replace it at only the return shipping cost. Out of warranty? We'll provide a quote for repairs.
