Frank Darling Discount Codes in September 2026

Yes. Verified military members, first responders, nurses, teachers, students, and government employees get $100 off. The part to know is that it only applies when you buy a setting and a certified loose diamond together, which is the custom build-your-own path, not a preset ready-to-ship ring. So if you qualify and you were eyeing a preset, building custom instead is what unlocks the $100.

Unlike big retailers, there is no instant ID.me or SheerID check at checkout. You message Frank Darling directly, send proof of your status, and they issue a one-time custom code. That extra step is why the discount is easy to miss, since it never shows up on product pages or coupon sites. Since you are already chatting with their team to design the ring, ask for the status code in that same conversation so it is ready when you check out.

For most shoppers, a wire transfer is the cheapest payment method, taking 1.5% off your total before checkout. The only thing that beats it is a credit card that earns more than 1.5% in cash back or travel points. Compare your card's earning rate against the wire discount before you buy to see which puts more money back in your pocket.

That card only comes out ahead when you pay the balance off that same month. If it earns less than 1.5%, or you would carry the balance and pay interest, the wire is the better call, and the flat 1.5% off is yours with no added fee.

The one limit on a wire is that it cannot be broken into smaller payments, so the full amount goes at once. For shoppers who would rather spread the cost, Affirm or Shop Pay Installments let you pay over time at rates that run from 0 to 36%, and they only save you money at 0%. Check the rate on the approval screen before you commit, since anything above 0% adds interest and quietly raises your total.

Setting up a wire is simple. Email their customer service, and they will send a link with your total after tax, plus the transfer details, and you finish the payment through your own bank with the discount already built in.

Yes. Eligible engagement rings and wedding bands get one free resize within 90 days of delivery, and you just cover shipping. After that, each resize is $100 plus shipping.

The part most people miss is not to rush the free one. Finger size drifts with heat, salt, and the time of day, and a new ring takes a few weeks to settle. Wear it, learn your true size, then spend your single free resize when you actually need it instead of on a guess. And do not book a paid resize just for shine either, since free cleaning and polishing are already yours for life.

One case works differently. A few styles cannot be resized at all, so they never get the 90-day perk, and the only no-cost fix is swapping for a new size inside the 30-day return window. If you are set on a style like that, lock in the size before day 30, because after that a size change means paying.

Both come free with your purchase, and you are covered the day the ring arrives, with nothing to register or activate. They split the work like this:

• Care plan: routine upkeep for the life of the ring

• Lifetime warranty: manufacturing defects only

Most shoppers use the care plan often and touch the warranty almost never.

On the care side, that means polishing, prong-tightening, steam cleaning, and re-dipping white gold when it yellows, which is normal rhodium wear and not a defect. Frank Darling does the labor free once a year, and you only pay insured shipping to send the ring in. Drop it off at a showroom instead, and you pay nothing. Sample-sale pieces and rings serviced elsewhere do not qualify.

On the warranty side, a covered defect means a prong or structural flaw from how the ring was made. The center stone and everyday wear are out, and after about six months most damage gets counted as normal wear, so real defect claims almost always surface early or not at all.

If any outside jeweler touches the ring, even for a free cleaning or inspection, Frank Darling can void the warranty and refuse the care work. So send the ring in or drop it at a showroom for your free annual service, and keep every other jeweler's hands off it. Between trips, clean it at home for free with warm water, a drop of dish soap, and a soft toothbrush
