I wish I could give Ritani 5 stars, but I have received only half of the diamonds I've ordered from them and while their prices can be excellent, that doesn't matter if the stone you want is not available. My first order of a lab created diamond went well and the price was fantastic. A second order also went well and the price was incredible. I always research the diamond by certificate # and it was clearly hundreds cheaper on Ritani. But a third order I was told the diamond had been sold. They tried to sell me on some other diamonds that were all inferior to the one I ordered, but to their credit they immediately credited my card when I said I did not want another stone. Following day the stone I was told was not available was back on their site at a higher price. I questioned them about this and they had no good answer. They did say the prices can fluctuate but this did not explain how it showed up back on their site. I did continue to buy from them, 2 more diamonds, but I also had 3 more orders where I was told the diamond I ordered was not available. In 2 of those instances the diamond reappeared on their site. For it to happen once I could believe their excuses, but not 4 times. To understand this fully, you have to understand that most of the online diamond sites are only brokers, the stones are overseas and will be sent to the store when you buy it. These stones are many times available on several sites at once with prices all over the place. At times, thousands of dollars in difference. The store loses nothing if your stone is not available because they're just going to try to sell you something else. In every case what Ritani tried to sell me was never the great deal like the stone I paid for. They never hesitated to credit my card back though. All 4 stones I did receive were fantastic prices, one of the best being a 3 carat cushion, before tax, for $787. All orders were sent within a reasonable time and well packaged with IGI certificate and appraisals. All sent by free FedEx shipping. It's a shame that in some cases they chose to do what seems to be a bait and switch, which might work on some guy looking to buy an engagement ring diamond but not on me. I started using another store with better prices, that is not as well known and when I check Ritani's prices overall they seem to have less deals. The last diamond I purchased, a 6.25 carat Pear, was more than $1000 less on the site I purchased it from than Ritani and I also noticed that after I bought it from the other broker, it still remained on Ritani's site as "available" for at least a week, when I knew it was not. Lately (August/September 2023) their prices have become much higher than their competition. Overall Ritani is worth checking out for their lab diamonds and if you see a great deal on a diamond your chance is about 50/50 that you'll actually receive it.
