How Le Fling works

How it works

01

Set your standards

Browse the safe and bag whatever you love. No commitment yet: the bag adds up the retail value and tells you which Fling fits.

02

Pick your first date

Check out with your invite code. Your pieces leave the Diamond District safe within 2 days, protected and tracked both ways.

03

Have a fling

Wear it constantly; that is the point of it. When you want something new, swap. A free swap every 3 months, and every dollar of credit rides along.

04

💍 Lock it down

Fall for one? Keep it. Everything you've paid comes off the member price, 20% under retail on pieces over $1,000. No interest, no fees, no down payment. The membership was the payment plan all along.

The house behind the safe

Since 1959, on 47th Street

Ultimate Diamond has made fine jewelry in New York's Diamond District for three generations: one family, one bench, one safe, and more than 1,400 public reviews averaging 4.8 stars. Every Le Fling piece is made and inspected by that house before it ships to you: real hands, a real bench, a real safe with a street address.

The idea in the safe

A diamond does not wear out, fade, or go out of style; it will look the same in a thousand years. A piece that permanent can make more than one person happy. That is the whole idea: open the safe to members, let the jewelry live on wrists instead of waiting in velvet, and let every dollar you pay build credit toward keeping the piece you fall for.

Built together

Le Fling is a partnership: Bill, who runs the house his family built, and Andrew, a longtime family friend who came in as a customer and co-founded Le Fling with him. Bill brings the house's sixty-plus years at the bench; Andrew built the membership and the site. Questions land with a person, not a bot: hello@lefling.com.

Before you join

Are the diamonds real?

Yes. Every piece features real lab-grown diamonds set in 14k or 18k solid gold, inspected by our in-house gemologists. Select pieces include an independent IGI or GIA lab report, noted on the piece. Lab-grown diamonds are chemically, optically, and physically identical to mined diamonds. The only differences are origin and price.

How does swapping work?

Each membership includes one free swap every 3 months. When you want something new, request a swap and queue your next piece. Send the current one back with its return label; your next piece ships the day it checks in at our safe. Need something new sooner than your free swap? Extra swaps are $15.

How does owning a piece work?

Every dollar you pay as a member goes toward owning. 100% of your monthly payment accumulates as ownership credit. That credit stays with you, not the piece, so you never lose progress when you swap. When your total payments reach the buyout price of the piece you are wearing, it is yours. For pieces over $1,000 retail, the member buyout price is 20% off retail. The longer you wear a piece, the less it costs to keep, and you can buy out whenever you are ready. No down payment, no interest, no buyout fee. Your membership is your payment plan.

Is there a minimum commitment?

Yes: memberships run a 3-month minimum, then continue month to month until you cancel. You can cancel anytime from your account; within the first 3 months it takes effect when the minimum term ends, and after that at the end of the month you've paid for. Just here for one occasion? The One-Night Stand is a 7-day rental, from $199, on any piece $1,000 and up, and its fee becomes credit if you join or buy within 60 days.

How does billing work?

You are billed monthly on your saved card, starting today and automatically each month until you cancel. Your bank may ask you to confirm the first charge (3-D Secure). 100% of every payment accrues as ownership credit.

What if I damage a piece?

Everyday wear is on us. A loose prong, a worn clasp, the normal life of a piece that gets worn: we made it, so we fix it, free. Shipping is insured and tracked both ways. And if a piece is lost or stolen, you are never on the hook for the retail sticker: the most you can ever be charged is the piece's member price, the same 20%-off price any member could buy it for, and your credit counts against even that. The worst case is that you accidentally bought it. We verify identity and payment before any piece ships.

Can I take jewelry on vacation?

Pieces must stay within the continental United States. No international travel, no freight forwarders. This is an insurance requirement.

Who makes the jewelry?

Le Fling is backed by Ultimate Diamond, a family-owned jewelry manufacturer in New York's Diamond District since 1959. Every piece is manufactured in-house and inspected by master jewelers before it ships, with independent IGI or GIA certification on select pieces. Straight from their safe to your door.

How is this so affordable?

Because the jewelry is made in-house and ships straight from the safe, there are no extra layers between the bench and your wrist. And since 100% of every payment comes back to you as ownership credit, membership is less a cost than a layaway you get to wear.

What happens when I cancel?

Cancel anytime from your account, online, in two clicks. Within your first 3 months it takes effect when the minimum term ends; after that, at the end of the period you've paid for. Return any pieces within 7 days of that date. No cancellation fee. The ownership credit you've built stays on your account, ready to put toward buying any piece you love whenever you come back. It is for keeping jewelry, not cashing out, and it does not disappear because you took a break.

What about shipping and insurance?

Free 2-day FedEx shipping both ways with signature required, and every shipment is insured in transit. While a piece is in your possession, everyday wear is covered free. If a piece is lost or stolen, report it within 24 hours (with a police report for theft), and the most you can ever be charged is the piece's member price minus your credit. Never retail.

Already own jewelry you want to trade?

We accept trade-ins. Send us your existing fine jewelry for a professional appraisal by our in-house gemologists. If we make an offer, you can take it as account credit toward your membership or a buyout, or we ship your piece back at no cost. No obligation, no risk.

Ready for your
first date?

Le Fling is invite-only while it is small, on purpose: founding members get a human on the other end and a safe that never runs thin. Leave your email and we will send your invite as spots open. Already holding a code? Skip the line: browse the safe and check out whenever you are ready.
