Choosing the perfect diamond, be it for an engagement, special occasion, or simply as a high-quality accessory for your own look, can be daunting. Finding the gem of the right quality that you can trust is important, given the significance that diamonds tend to have.
As such, where you buy your stones is just as important as the stones themselves. As online marketplaces continue to grow, more and more buyers are looking to digital platforms to help them find their ideal diamonds.
One such platform getting more attention is Rare Carat. Here, we’re going to review Rare Diamond, looking at what it is, how it works, and whether it’s a reliable and valuable option for those looking to buy diamonds in 2025.
Introducing Rare Carat
Rare Carat was founded in 2016 by Ajay Anand, inspired by his own challenges when trying to purchase an engagement ring online. Against the backdrop of opaque price ranges and overwhelming options, he opened a marketplace that aimed to simplify the process, combining advanced technology with expert advice.
As a marketplace, not a traditional store, Rare Carat combines listings from a range of wholesalers and retailers, all having gone through a stringent vetting process to maintain a certain high standard. Powered by IBM Watson AI tools and GIA-certified gemologists, Rare Carat provides accurate and fair assessments for its shoppers, as well.
Why Choose an Online Marketplace for Diamonds?
Purchasing diamonds traditionally would see you visiting brick-and-mortar stores, but like everything else, they have gone online. Marketplaces are beginning to stand out from retailers for a host of reasons, as well, including:
- Broader Selection: These marketplaces pool diamonds from a wide range of vendors, offering more variety to buyers.
- Price Competition: Multiple vendors competing in the same place often leads to prices more reflective of real market value rather than overinflation.
- Transparency and Education: Detailed filters and educational resources help demystify the diamond buying process, helping buyers be more informed with their choices.
- Consumer Protection: Reputable marketplaces vet their sellers and offer policies to protect the customers.
This shift towards online buying reflects changing consumer habits and a desire for greater convenience and clarity in what has historically been a complicated purchasing process.
What Rare Carat Offers to Buyers
As a marketplace, Rare Carat is not just a listing site; it’s a full-service diamond and jewelry platform. It offers a selection of both natural and lab-grown diamonds, as well as Moissanite, a popular diamond alternative known for its brilliance and affordability. Their selection also includes engagement rings, wedding bands, earrings, necklaces, and bracelets.
The platform runs alongside an AI-driven search engine, which sifts through over a million diamonds to present options that match the buyer’s specific criteria. This also contributes to a Deal Score, a metric that evaluates each diamond’s price relative to quality and market value.
Rare Carat also offers free access to GIA-trained gemologists through chat or phone consultations, providing personalized advice and answering any questions about the diamond buying process. Those seeking more guidance can also look to their Diamond Concierge Service, which walks buyers through the whole process with tailored support to suit their needs.
Benefits of Shopping with Rare Carat
There is a whole range of advantages that stand out when using Rare Carat as your shopping platform of choice, especially for those who want to make confident and informed diamond purchases. These include the following:
- Data-Driven Shopping Experience: The AI that powers the site helps customers filter their choices, with options to choose based on cut, clarity, color, and carat. The Deal Score offers an immediate and objective value of whether or not the diamond is a good value buy at the price it’s offered, too.
- Expert Advice: A team of independent gemologists helps customers get unbiased information about the diamonds they’re looking at, including any potential issues like treatments or fluorescence that might affect their appearance or durability.
- Customer-Friendly Policies: Rare Carat stands out for its focus on customer satisfaction beyond the products themselves, including a 30-day money-back guarantee that means buyers can return their purchases if they don’t meet expectations, as well as 90-day resizing options to adjust rings if their size fit isn’t perfect.
- Secure Shipping: Orders are shipped insured and require a signature on delivery, providing security and peace of mind. Packaging is elegant, creating a memorable unboxing experience.
Add all of this to their wide selection of diamonds from vendors across the globe, and buyers can easily find the stone that matches their preferences and budget.
Drawbacks to Consider
Although there are plenty of benefits, Rare Carat also has a few limitations to be mindful of, including the following:
- No Physical Store: Since they operate entirely online, Rare Carat shoppers can’t see or try on jewelry in person before buying. Though their 360-degree views help, some customers still prefer the more hands-on experience.
- Dependent on Partners: As Rare Carat aggregates listings from third-party sellers, the availability and shipping times of products can sometimes vary. Changes in inventory or delays are outside Rare Carat’s direct control.
- Information Overload: Understanding diamond grading, certification reports, and the other technical aspects of diamonds can be intimidating for first-time buyers. Rare Carat does offer more educational and support resources to make it easier, but if you want to get a detailed understanding, you have to put in a little effort..
- US-Focused: Many of the perks, like free shipping, returns, and resizing, may not be available depending on where you are.

If your priority is finding a trustworthy platform that makes buying diamonds more accessible across multiple sellers with expert advice, Rare Carat is a standout option. Its combination of AI-powered pricing analysis and human gemologist expertise offers a rare blend of convenience, transparency, and confidence in online diamond shopping.
