Frequently Asked Questions

Does Gem & Harmony give new customers a discount for signing up?

Yes. Subscribing to the Gem & Harmony email list unlocks a 20% off code, GEM20G, which gets entered at checkout. The email arrives right after signup, so it's worth doing before browsing rather than after adding items to the cart.

What is Gem & Harmony's return policy?

Orders can be returned for a refund or exchange within 30 days of the shipment date, not the delivery date, so the clock starts as soon as the package leaves the warehouse. A Return Authorization number is required first, and the item has to come back in the same condition it was sent in.

Are engraved or custom sized pieces returnable?

No. Custom orders, including engraving and rings resized outside the standard range, are excluded from the 30 day return policy entirely. Anyone ordering a customized piece should be confident in the sizing and wording before submitting the order, since there's no refund path afterward.

Is shipping free at Gem & Harmony?

Orders over $99 ship free. Below that threshold, standard USPS First Class shipping runs about $1.99 and takes 3 to 7 business days, with faster paid tiers available for anyone who needs a piece sooner.

How fast can I get a ring or necklace from Gem & Harmony?

Expedited USPS Priority runs 2 to 5 business days for $7.99, Express Delivery is 2 to 3 business days for $11.99, and Overnight Delivery arrives in 1 to 2 business days for $24.95. Custom pieces are the exception, since those take a minimum of two weeks to produce before they even ship.

Does Gem & Harmony ship outside the continental United States?

Canadian orders are accepted for a flat $7.95 handling charge in addition to standard shipping, and typically arrive in 6 to 10 business days. Alaska, Hawaii, and APO or FPO addresses ship through USPS with a $12.95 surcharge and should be expected to take a few extra days.

What happens if I return an item without a Return Authorization number?

It gets rejected. Gem & Harmony's warehouse won't process a refund on a package that arrives without an RA number attached, so the first step in any return is contacting customer service to request one rather than mailing the item back directly.

 

Does Gem & Harmony deliver to P.O. boxes?

No. Every order requires a physical address and an adult signature on delivery, since Gem & Harmony insures and registers shipments for their full value as a theft precaution.

Saving Guide

Why Gem & Harmony's coupon page earns a second look:

A lot of jewelry sites reserve their real discounts for holiday weekends. Gem & Harmony leans the other direction, with a standing 20% off newsletter code that applies to nearly any order, which makes the coupon page worth checking even on an ordinary Tuesday shopping trip.

Start with the newsletter code:

Signing up for emails before adding anything to the cart triggers the GEM20G code for 20% off. Because it's tied to email signup rather than a specific sale event, it's available to first time shoppers year round, not just during a promotional window.

Hit the free shipping threshold on purpose:

Orders of $99 or more ship free, while anything under that pays a shipping fee starting around $1.99. A single mid range pendant or a pair of stud earrings often lands right at that line, so it's worth checking the cart total before checkout, since a small add on item can sometimes save more in shipping than it costs.

Factor in customization timing and cost:

Engraving or a ring resized outside the standard range adds a minimum two week production window and removes the piece from the 30 day return policy entirely. For anything time sensitive, like an engagement or anniversary date, that extra lead time is worth building into the order well before checkout, since custom orders can't be canceled once they're in production.

Before you check out:

Confirm the order total against the $99 free shipping line, double check ring size and any engraving text since custom pieces can't be returned, and hold onto the Return Authorization process in mind for standard items in case a piece needs to go back.
