An oval is the shape that flatters the hand before it flatters the stone. Four carats, elongated, on a band that never stops catching light. A 4.00 carat oval cut lab grown diamond, E color, VS1 clarity, IGI certified. The shoulders carry 1.10 carats of round accents at 2.70 millimetres each, pave set and running well past the halfway point of the band rather than stopping at the head. 5.10 carats in total. An oval reads longer than a round of the same weight, which is why a 4 carat oval wears larger than a 4 carat round on the same finger.

How to Size It +

Not sure of your size? Message [email protected] before ordering and a ring sizer ships to you free. One complimentary resize is included within 60 days of delivery.

A 4 carat oval measures roughly 12 by 8 millimetres. Set lengthwise along the finger it reads longer than a round of the same weight, and it suits a size 5 through 8 without looking crowded.

White metals keep the stone reading cool and bright. Yellow gold warms it. Platinum is the heaviest and the most hypoallergenic. All options come in solid 10K, 14K, 18K.

Care is simple. Warm water and a soft brush. Remove before lifting weights or working with harsh chemicals. The setting is designed for daily wear.

Questions
How big does a 4 carat oval look on the hand? + An oval is elongated, so it covers more of the finger than a round of the same weight. A 4 carat oval measures roughly 12 by 8 millimetres and its length spans about two thirds of the width of an average ring finger.
What does VS1 clarity mean? + Very Slightly Included, first tier. Inclusions are difficult to find at 10x magnification and invisible to the eye. It sits a grade above the VS2 that most retailers stock at this carat weight.
Do the accents run all the way around the band? + No. The pave runs along both shoulders and past the halfway point, then the band finishes plain underneath. That keeps the ring comfortable and makes resizing simple.
Are lab grown diamonds real diamonds? + Yes. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds. A gemologist cannot tell the difference without specialized equipment. The FTC confirmed their equivalence in 2018.
Can the ring be resized? + Yes. One complimentary resize is included within 60 days of delivery. After that a small jeweler fee applies. Message [email protected] to arrange.
Which metal should I choose? + White metals keep an oval reading bright and cool. Yellow gold warms the stone and softens its edges. Platinum is dense, hypoallergenic and never needs re plating. All options come in solid 10K, 14K and 18K.

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 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.

If you need to send a piece back within 30 days, contact us for return instructions.

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. 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 [email protected] with your order number and we respond within 24 hours with return instructions 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.
