About DiamondCodes

What we do

DiamondCodes tracks prices and coupon codes across many online jewelry retailers, so it's easier to find the right ring at a fair price — and to know whether a discount code actually works before you reach checkout.

Some rings — classic solitaires, for example — are sold by many stores in nearly identical form, and those compare cleanly side by side. Plenty of others are exclusive to a single retailer, or differ in small details from one store to the next. In those cases we surface the closest matches we can find, so you can weigh similar rings rather than guess at how they stack up.

Why we exist

Online diamond shopping is fragmented. There are many reputable retailers, each with its own inventory and its own way of presenting prices, and no easy way to look at them side by side. For most shoppers that means opening a dozen tabs and trying to remember which ring is which.

Lab-grown diamonds have changed the market quickly over the past few years, and prices for similar rings can vary by hundreds — or sometimes thousands — of dollars between stores. Seeing the range in one place, alongside whatever discount codes are currently floating around, makes the decision a lot simpler.

That's what DiamondCodes is for: a single place to look at similar rings across many stores, with coupon codes collected alongside them, and guides that explain the tradeoffs that actually matter.

What's on the site

• Prices from many retailers, kept reasonably current. We re-check prices on a regular cadence, so when a store puts a ring on sale or changes the price, the listings here move with it. It isn't a real-time feed and there can be a short lag.
• Coupon codes we try to keep working. Codes come from retailer promotional pages and reader tips. We check them where we can and clear out ones we know have expired, but a code can still stop working between check and checkout. If one doesn't apply at the cart, let us know and we'll pull it.
• Side-by-side comparison for finished rings. We match rings with the same shape, metal, carat, and setting across stores so you can see who's priced competitively on the kind of ring you're looking at. For one-of-a-kind designs, the closest we can do is "similar," and we say so.
• Editorial guides with sourced facts. Our buying guides cite primary sources — GIA, IGI, named studies, retailer documentation — rather than recycling other blogs.

What we're not

A few honest limits. We're not a retailer — we don't sell rings, hold inventory, or take orders. Every purchase happens on the retailer's own site; our job ends at sending you to the right page.

We don't appraise diamonds and we don't offer gemological consulting. When we talk about cut grades or fluorescence or the difference between GIA and IGI, we're summarizing publicly documented standards from the grading labs themselves, not issuing opinions as certified gemologists.

For factual claims about diamonds — the science, the grading scales, the market data — we cite primary sources in every guide we publish (GIA, IGI, named studies, retailer documentation). When a guide expresses a view on a tradeoff, it's the site's editorial view, informed by what the data shows and what we'd tell a friend who asked.

How we make money
