The size is a guess
A proposal buyer can't ask for a ring size without giving the game away. Whether you resize for free, how many sizes a band can move and which styles can't be resized at all decide whether a guess feels safe.
Jewelry and engagement rings
AI voice agents for jewelry brands that answer ring size, stone and delivery questions
An engagement ring buyer may not know the ring size, may not have seen the stone in person and may need the ring before a set date. A Loop Voice agent reaches them after they leave checkout, answers from your listings and policies, says "lab-grown" every time it describes a lab-grown stone and quotes ship times without promising a carrier's delivery day.
The short answer
A jewelry brand's AI voice agent phones buyers who left checkout and settles what a listing can't: ring size and resizing, lab-grown or mined, what the grading report says, and whether the piece ships before a date. It calls every lab-grown stone lab-grown, as the FTC's Jewelry Guides expect, and quotes ship times without promising delivery. No jewelry store's Loop Voice results are published yet, so measure answer rate, attributed orders and how many calls turn on a deadline.
Why a ring order stalls
Lab-grown or mined
The two can look the same to a buyer and be priced very differently. Shoppers want the difference explained without a pitch for either, and the FTC's Jewelry Guides spell out which words mislead.
The report has to match the stone
Carat, color, clarity and cut grades, the grading lab and the report number. A buyer spending this much wants to know the stone in the box is the one on the report, read back in plain words.
There's a date on the calendar
An anniversary, a birthday, a dinner reservation with a question attached. Made-to-order settings, engraving and signature-required delivery all stretch the timeline, and a buyer unsure it arrives in time may not risk the order.
Where calls earn their place in a jewelry store
Call the ring buyer who left checkout
The agent calls about stone, size and date, texts the checkout link and stops once the order is placed. For buyers who research for weeks, you can also follow up on abandoned carts from up to 30 days back.
See the use caseCall back custom design requests
A shopper who fills in a custom ring form and agrees to calls can hear back within minutes. HubSpot CRM events and form tools connected through Zapier can start the flow, and the agent gathers budget, stone preference and timeline before a designer takes over.
See the use caseFollow up a missed consultation
Calendly bookings, cancellations and no-shows can each start a flow. A buyer who agreed to calls when booking, then missed a video consultation, gets a call while the ring is still on their mind and hears how to book a new time from what you've loaded.
See the use caseAnswer the will-it-arrive call
Inbound, the agent handles order status, resizing terms and care questions, and during support hours it can put a high-value caller through to your jeweler.

AI agent
Hi, it's Casey, an AI assistant calling from [Store]. If you'd rather not get these calls, just say stop. Am I speaking with Chris?
Shopper
Yes, that's me.
AI agent
Thanks, Chris. The oval solitaire is still in your cart. Any questions I can answer before you decide?
Shopper
Is the diamond real? And I don't know her ring size.
AI agent
It's a lab-grown diamond, not a mined one, and the listing shows its IGI grading report number. We resize once for free within 60 days, and an unengraved ring can come back within 30 days.
Shopper
I'm proposing on the 14th. Will it get here?
AI agent
The listing says it ships in 5 to 7 business days, insured, and someone has to sign for it. I can't promise the day the carrier delivers, so count back from the 14th with that in mind. Should I text you the checkout link?
Shopper
Do that. Thanks.
What ring buyers ask, and what the agent says
What shoppers say
“Is a lab-grown diamond a real diamond?”
How the agent answers
It answers without "real", "genuine" or "natural", which the FTC's Jewelry Guides treat as deceptive for anything made artificially. It says the stone is a lab-grown diamond, not a mined one, and reads the grading details from your listing.
What shoppers say
“If I engrave it, can I still return it?”
How the agent answers
It reads your return exclusions as written. If engraved rings are final sale, it says so before checkout, along with the days engraving adds before the ring ships.
What shoppers say
“Will it arrive before the 14th?”
How the agent answers
It quotes the ship time and shipping method on the product page and won't promise a delivery day it can't control, however close the date is.
What shoppers say
“How do I know it's the stone on the certificate?”
How the agent answers
It reads the grading lab, report number and grades listed for that stone, plus any laser inscription your listing mentions. Anything the listing doesn't cover, it won't confirm; the question lands on the answer gaps list, and you can call or text the buyer again from their profile once you know.
What shoppers say
“Is there a payment plan?”
How the agent answers
It names the payment options your checkout shows, if they're in the knowledge base, and stops there; comparing plans or rates is off limits under the no financial advice guardrail.
Setting up a jewelry agent
Connect the store in Settings, Integrations, whether it runs on Shopify, WooCommerce or Checkout Champ. If custom work starts with an inquiry form, connect HubSpot or Zapier; if it starts with a booked consultation, connect Calendly with OAuth. Those events can then start flows.
Give the knowledge base every stone's details: lab-grown or mined, grading lab, report number and grades, metal and karat, sizes and resizing rules, made-to-order lead times, shipping and signature rules, and return exclusions.
Add custom guardrails for the FTC wording: "lab-grown" goes right before "diamond" for every lab-grown stone, and the words real, genuine and natural never describe one.
In the abandoned checkout flow, choose what the second call carries: a code you've allowed, capped at your maximum value, or just your resizing and return terms.
Under Settings, Support, Transfer to your team, set your support hours so a buyer with a custom-setting question reaches your jeweler. Outside those hours, the question becomes a ticket for the jeweler.
Call only buyers who gave prior express written consent to AI-voiced marketing calls, and read the calling rules guide for what that consent has to include. Loop Voice dials only within your store's hours, in each buyer's time zone.
Test the wording rules in the simulator with a one-off customer who insists lab-grown means fake, and check that the agent never answers "is it real?" with a yes.
Jewelry rules the agent follows
- Say lab-grown, right before the stone's name. In April 2019, FTC staff warned eight jewelry marketers that a lab-created diamond's name must be immediately preceded by a clear and conspicuous disclosure that it isn't a mined stone, and the Jewelry Guides list "laboratory-created", "laboratory-grown" and "[manufacturer name]-created" as wording that conveys a diamond isn't mined.
- No "real", "genuine" or "natural" for lab-grown stones. Section 23.27 of the Guides treats those words, along with "precious" and "semi-precious", as unfair or deceptive for any product made artificially. A shopper who asks "is it real?" hears "it's a lab-grown diamond" instead.
- The FTC's Mail Order Rule is about when you ship, not when the ring arrives: its business guide defines shipment as placing the merchandise in the carrier's hands. Any ship time you state needs a reasonable basis, setting and engraving time included, and if a ring can't go out on time, the buyer chooses between accepting the delay and canceling for a prompt refund. Have counsel check your delay process.
Questions
How should an AI agent describe a lab-grown diamond?
As a lab-grown diamond, every time, and never as "diamond" alone. If you also sell simulants, the Guides want "imitation" or "simulated" right before the gem name, so load the exact name each listing uses and the agent repeats it.
Can the agent help a buyer who doesn't know the ring size?
Within your policy, yes. It reads out your sizing guide, how many free resizes you offer and for how long, and any styles you don't resize, so the buyer knows what a wrong guess costs before checkout. It won't guess a size for someone it can't see.
What if the ring is a surprise and someone else answers?
Add the verify identity objective, and write into the prompt that the agent confirms it's speaking with the buyer before it mentions an order and says nothing about a ring to anyone else, as the call above does. Texts can carry a product merge field, so leave the product name out of the text template if a partner might see the phone.
Which jewelry shoppers should get a call?
Buyers who agreed to calls and then left checkout on a ring or another high-value piece, asked for a custom design or missed a booked consultation. For low-priced fashion pieces, a cart-value branch sends a text instead of a call.
Can the agent transfer a caller to a jeweler?
Yes, during the support hours you set. It briefs your teammate before connecting, and if nobody picks up before the ring time runs out, it opens a ticket with the call summary.
What should a jewelry store track before judging the calls?
How often buyers pick up, orders credited to each flow, and which of size, stone origin or a deadline comes up most. As a reference across all stores, 16.5% of shoppers called after abandoning checkout picked up at least once in Loop Voice's September 2026 benchmark, which has no jewelry cut yet.
