What the EX3 Diamond Warranty and Resizing Policy Actually Covers

Buying a diamond ring is a significant purchase, and most buyers want to know what happens after the sale - if a prong loosens, if the ring needs to be resized, or if something goes wrong. The EX3 Diamond warranty and service policy covers more than most buyers expect, but the details matter.

This is a plain-language breakdown of exactly what the EX3 Diamond warranty covers, how the resizing process works, what the repair timeline looks like, and what to do if you need to use it.

The 180-Day Warranty: What Is Included

Every piece of jewelry purchased from EX3 Diamond comes with a 180-day warranty. That is six months of coverage starting from your delivery date - not the purchase date.

The warranty covers two categories of issues:

Workmanship defects. If a prong bends or breaks, a clasp fails, a chain develops a weak link, or an earring post cracks, that is a manufacturing defect covered under warranty. EX3 Diamond will repair or address the issue at no charge.

Diamond loss under 1/5 carat. If a melee stone - one of the small accent diamonds in a pave band, halo, or side stone setting - falls out during normal wear, and that stone is under 0.2 carats, the warranty covers its replacement. This is a meaningful protection for buyers choosing rings with lots of small stones, where stone loss is the most common post-purchase concern.

What Specific Services Are Covered

Within the 180-day warranty window, EX3 Diamond covers the following services:

• Ring resizing and re-shanking: Adjusting a ring to fit a different finger size, or replacing a worn or damaged shank.
• Prong repair: Re-tipping or rebuilding prongs that have worn down or been damaged.
• Clasp replacement: Replacing a broken or malfunctioning clasp on a bracelet or necklace.
• Chain repair: Fixing a broken chain link.
• Earring post repair: Repairing or replacing a bent or broken earring post.
• Minor scratch removal: Light polishing to remove surface scratches from the metal.

These are the services that typically come up in the first six months of wearing fine jewelry - the period when fit issues are identified and any manufacturing weaknesses show up.

Ring Resizing: The Full Picture

Ring resizing is one of the most common post-purchase requests. EX3 Diamond allows resizing within the 180-day window from your delivery date - the same timeline as the warranty.

The process is straightforward: contact the EX3 Diamond team to initiate a resize, and they will walk you through what to send and where to send it. Once received, the ring goes through inspection, the resize is performed by their bench jeweler, and the ring is returned to you. The turnaround time for repairs and resizing is up to 10 business days from the time EX3 receives the piece, and they will notify you when it is ready and on its way back.

If you are unsure of your ring size before purchase, EX3 Diamond recommends getting sized by a local jeweler before ordering. Many jewelry stores will measure your finger for free, and it is worth doing - shipping a ring back and forth takes time, and the closer you are to your correct size from the start, the better.

The Warranty Upgrade Option

EX3 Diamond offers an extended warranty upgrade at the time of purchase. This extends the coverage period beyond the standard 180 days, giving buyers additional protection for repairs, resizing, and diamond loss.

If you are buying a ring with a lot of pave work, or if you know you will be wearing your jewelry in demanding conditions (high-contact work environments, frequent outdoor activities), the upgrade is worth evaluating at checkout. It is available only at the time of purchase - it cannot be added after the fact.

The Repair and Warranty Service Process

The EX3 Diamond service process follows three steps:

1. Inspection. When your piece arrives, the EX3 team examines it to assess the issue - what happened, what needs to be done, and whether it falls within warranty coverage.
2. Gemologist examination. A trained gemologist reviews the stone and setting to ensure the repair plan is appropriate and that no other issues need to be addressed.
3. Solution offered. EX3 communicates what they will do and, where relevant, any costs outside warranty scope. For in-warranty repairs, you receive the outcome - repair completed, replacement stone set, or alternative resolution.

The standard service timeline is 2-4 weeks from the time EX3 receives your piece. Most repairs take up to 10 business days once in hand, with return shipping adding time on either end. Plan for the full range when deciding whether to send a piece in.

Returns and Exchanges

Separate from the warranty, EX3 Diamond allows returns within 30 days of delivery. The piece must be unused and unaltered - returned in the same condition it was received. If you have already had the ring resized or worn it significantly, a return is generally not available.

Exchanges are also available. If you want to swap for a different diamond, setting, or ring style, contact the EX3 Diamond team to understand the process for your specific situation.

Every shipment from EX3 Diamond goes out insured with signature required on delivery - so the piece is protected in transit and properly documented as received.

Appraisal for Insurance

EX3 Diamond offers a jewelry appraisal for $39.99, recognized by all American insurance companies. A written appraisal is what your homeowners or renters insurance policy needs to add your ring as a scheduled item - which means it is covered against loss, theft, or damage beyond what a standard personal property policy covers.

For most engagement ring purchases, getting an appraisal and adding the ring to your insurance policy within the first few weeks is worth doing. The $39.99 is a one-time cost; the annual insurance premium on a $5,000-$10,000 ring is typically $50-$150 per year - and you are covered if the ring is ever lost or stolen, which the manufacturer warranty does not address.

You can explore EX3 Diamond IGI-certified lab-grown diamonds and pair any stone with a setting to build a custom engagement ring backed by this warranty from the moment it ships.

Frequently Asked Questions

Does the warranty cover accidental damage?

The standard 180-day warranty covers workmanship defects - issues that arise from how the piece was made. Accidental damage from drops, impacts, or unusual wear is generally not covered under the standard warranty. The warranty upgrade option at time of purchase may offer broader coverage; contact EX3 Diamond for specifics on what the upgrade includes.

What if a diamond larger than 0.2 carats falls out?

The standard warranty covers diamond loss for stones under 1/5 carat (0.2 ct). If a larger center stone or significant side stone comes loose, contact EX3 Diamond immediately - they will inspect the piece and determine what happened. Prong failure (a manufacturing defect) would be covered even for larger stones; loss due to impact or damage would be evaluated case by case.

How do I know if my ring can be resized?

Most rings can be resized, but some designs are more difficult than others. Rings with continuous pave or eternity-style stone settings around the full band are harder to resize because the stones may need to be repositioned. Rings with simple metal shanks - solitaires, most three-stone styles - are straightforward. The EX3 Diamond team can advise on your specific ring before you initiate a resize.

Can I get an appraisal after I have already purchased?

Yes. The $39.99 appraisal service from EX3 Diamond is available independently of the purchase. Contact their team to initiate one. Alternatively, local jewelers and independent appraisers can also provide appraisals for insurance purposes - typically for $50-$150 - if you prefer an in-person evaluation.

What happens if I miss the 180-day warranty window?

EX3 Diamond can still provide repair and service after the warranty period, but these would be at standard service rates rather than covered at no charge. Regular maintenance - having prongs checked, stones inspected, and metal polished - every 12-18 months keeps jewelry in better condition and can catch small issues before they become larger ones. Visit EX3 Diamond engagement rings to learn more about their ongoing care recommendations.

Does the warranty transfer if I give the ring as a gift?

The warranty is tied to the original order, not a specific person. If you purchased the ring and it was given as a gift, the 180-day warranty from the delivery date still applies - the recipient can initiate service using the original order information. Contact the EX3 Diamond team if there is any question about coverage for a gifted piece.

The Bottom Line

The EX3 Diamond 180-day warranty is a substantive policy: it covers workmanship defects, melee diamond loss, resizing, prong repair, clasp replacement, chain repair, earring post repair, and scratch removal - the full range of issues that typically come up in the first six months of wearing fine jewelry. The service process is structured, with inspection and gemologist review before any resolution, and the turnaround time is up to 10 business days once the piece is in hand.

The additions worth knowing about: the warranty upgrade at checkout for extended coverage, the $39.99 appraisal for insurance purposes, and the 30-day return window for unused pieces. Together, these give buyers a clear picture of what they are protected against and what steps to take if something goes wrong.

If you have questions about coverage for a specific ring or diamond before you buy, the EX3 Diamond team is available by phone and email during business hours - and they are the right people to ask before making a purchase decision, not after.
