Sizing & Styling +

Standard ring sizes 4 to 10 available. The pavé band can be resized within two sizes of the original cut, beyond that the integrity of the diamond setting is compromised. Specify your size at checkout. Free first resize within 60 days of delivery if you guessed wrong.

Wears on the ring finger as engagement, anniversary, or right hand statement. The width and visual weight balance best on the dominant hand for right hand wear. Pairs with a plain band stacked above or below as a wedding set, ask us to make one to match.

White gold and platinum keep the focus on the diamonds and the architectural lines. Yellow gold warms the radiant and reads more vintage. Rose gold sits romantic and flatters warm skin. Silver delivers the white gold effect at the lowest price point. Platinum is the most durable for daily wear and recommended for engagement use.

Other jewelry should match the tone of this ring. Worn with simple studs, a thin necklace, or a watch. Skip large rings on the same hand, the radiant is the focal point and needs space around it.

Occasion Guarantee +

Buying this for a specific occasion? Email us your date at info@dracodiamond.com before or after ordering. We confirm in writing whether we can deliver in time. If we confirm and miss the date through our fault, the piece is yours free. Full refund. You keep it. No other lab diamond brand offers this in writing.

Questions
Can this be worn as an engagement ring? + Yes. The 3 carat radiant center, IGI certified diamond, and traditional 4 prong setting meet every standard for an engagement ring. It also functions as a right hand statement ring, an anniversary ring, or a milestone piece. The design intentionally crosses categories so you can wear it on either hand and have it read correctly. A matching plain band can be paired with it as a wedding set on request.
How does a radiant cut differ from emerald or princess? + Radiant combines the silhouette of an emerald cut (elongated rectangular shape with cropped corners) with the brilliant cut faceting of a round or princess. The result is the visual length of an emerald with the fire and sparkle of a round. It is the only step shape that scintillates like a brilliant. Developed in 1977 by Henry Grossbard, it has become a favorite of celebrities including Jennifer Lopez and Megan Fox.
Will the twist band catch on things? + The 2.7mm tapered band sits flush against the finger without protruding ridges. The pavé diamonds are bead set into the band, not raised. The marquise leaf clusters on the shoulders sit angled inward, not outward. Hair, sweaters, and gloves do not catch in normal wear. We do recommend removing it for high impact activities like lifting weights or rock climbing.
Can the center stone be resized or replaced later? + The ring itself can be resized within two sizes either direction. Upsizing or downsizing further would compromise the integrity of the pavé band and is not recommended. The center stone is replaceable at our workshop if you want to upgrade carat weight in future, charged at the difference in diamond cost plus a small reset fee. Email info@dracodiamond.com for the upgrade program.
Which metal should I choose? + White gold and platinum let the radiant and marquise diamonds do the work, the cleanest, most modern look. Yellow gold warms the stones and reads more vintage. Rose gold sits romantic and pairs well with warmer skin tones. Platinum is the most durable for daily wear and never needs replating, ideal for an engagement ring. Silver delivers the white gold effect at the lowest price point. All gold options are solid 10K, 14K, or 18K, never plated.

We are committed to making your entire experience a pleasant one, from ordering to delivery.

Every Draco Diamond piece is built to last. Solid gold settings, not plated. Prongs set to hold. Clasps and links engineered for daily wear, not display. Each stone is IGI certified VS+ clarity minimum, E-F color, individually verified against its grading report before it ships. If a piece does not meet that standard, it does not leave. What arrives at your door is built the way a piece at this price point should be built — and backed by a lifetime authenticity warranty if it ever falls short.

Your piece does not exist until you order it. Every Draco Diamond is made to order in 1 to 2 weeks, then inspected against its IGI certificate before it ships. This is how we guarantee you receive a new piece built to your exact specifications, not something pulled from inventory that has been handled before.

Made to order does not mean harder to return. Our 30-day return window, free prepaid label, and full refund apply regardless of how your piece was produced. If it is not right, the return process is identical to any standard online purchase.

Every order ships free via fully insured carrier with signature-required delivery and real-time tracking. Your piece arrives in 14 to 21 days from order — 1 to 2 weeks production followed by 2 to 7 days shipping depending on your location. All shipments are insured for the full purchase price at no additional cost.

Return shipping is also free. If you need to send a piece back, we provide a prepaid fully insured return label. You pay nothing in either direction.

All shipments arrive in unmarked outer packaging with no external branding or indication of contents. The shipping label shows only our business name. Inside, your piece is presented in full Draco Diamond premium packaging. This protects both security during delivery and the surprise for any gift or proposal.

Return any unworn piece within 30 days of delivery for a full refund. We pay return shipping both ways. We provide a prepaid fully insured return label at no cost to you. No restocking fee. No conditions beyond the piece being unworn and returned with original packaging and IGI documentation.

Made to order does not affect this policy. The return process is the same regardless of how your piece was produced. Email info@dracodiamond.com with your order number and we respond within 24 hours with a return label and clear next steps.

Every Draco Diamond piece is guaranteed to be exactly what its IGI certificate states. Forever. This covers:

  • Diamond specifications — carat weight, color grade, clarity grade, and cut grade match the IGI certificate exactly
  • Metal purity — 10K, 14K, or 18K gold as specified, verified against stated standards
  • Authenticity — every diamond is a genuine IGI certified lab-grown diamond, chemically identical to mined diamonds
  • Manufacturing integrity — settings, prongs, and clasps built to hold

If the piece ever fails to match what is certified, we fix it, replace it, or refund it in full. Your choice. At no cost to you. This guarantee does not expire.

Every diamond is certified by the International Gemological Institute, the world's leading independent grading authority for lab-grown diamonds. Your IGI certificate documents exact carat weight, color grade, clarity grade, cut quality, polish, and symmetry. It is an independent third-party record of exactly what you received.

Every piece is verified against its certificate before it ships. If a piece does not match its IGI specifications, it does not leave. The certificate ships with your order. You can verify any certificate independently at igi.org/verify using the report number on your document.

Every piece arrives in Draco Diamond presentation packaging designed to hold the piece safely and present it well. Engagement rings arrive in a deluxe presentation box ready for a proposal moment. All pieces include the IGI grading report, a Draco Diamond authenticity document, and a care guide. The packaging also serves as long-term storage for your certificate and documentation.
