Independent deals guide
See current Ritani offers and promo codes, plus our advice on loose-diamond prices, setting discounts and when a Ritani sale is worth using.
Ritani is one of our favorite places to compare lab-grown diamond prices. Its appeal starts with the price of the stone, not only the promotion. We also value being able to get help choosing a diamond without being pushed toward a more expensive purchase.
This page shows Ritani offers only. The overview highlights one promotion, while the full list includes the others so you can find the offer that suits your purchase.
Some retailer links may be affiliate links, and LabGrownCarats may earn a commission if you buy through them. Source links may be untracked. Compensation does not determine our verdicts, test results, or the evidence we report.
Check the offer's spending requirement and exclusions before choosing your jewelry. One highlighted offer; see the full list below for any others.

Begin with the loose diamond and add the setting before judging a ring discount. A setting promotion may cover only part of the order. Our Ritani review explains why we rate its diamond pricing highly and what to consider when buying.
For earrings or a pendant, compare the complete piece: diamond weight, metal, dimensions and any included chain. If an offer gives you a gift rather than a lower price, choose the main purchase first and treat the gift as an extra.

Ritani can run several promotions at the same time, with different eligible products and spending requirements. Check the current list above rather than assuming one code covers the whole store. Holiday names and dates from an earlier year do not establish this year's sale schedule.
For a specific occasion, our Ritani Mother's Day guide includes earring and pendant ideas. You can also compare the wider market in our Black Friday guide.
Narrow the shape and budget first, then compare diamonds with similar grades and grading reports. Look at available videos and dimensions, and ask for help if two stones look similar on paper. The cheapest result is a starting point for comparison, not an automatic winner.
Our diamond price guides compare defined groups of stones so you can judge the price without mixing very different specifications.
Check the offer's eligible products, any minimum spend and the final discount. Confirm the delivery estimate for your chosen setting or jewelry, especially if it is needed for a proposal or gift.
Our jeweler ratings and recommendations come from the research and purchases described in the linked reviews. Offers are checked separately: we show the spending requirement and end time when available, and link to the seller's full terms. An advertised saving is not proof of a historical low. We do not reuse expired codes or assume future holiday promotions have been announced.
