That’s where this guide comes in. Read on to discover the seven best places to buy diamond jewelry in 2025.
1. RareCarat: The Best All-Round Brand.
Rare Carat is widely regarded as America’s leading diamond jewelry brand. As a result, it is no surprise whatsoever that it has earned the number one spot on this list!
If you aren’t already familiar with this leading brand, it is essentially an online marketplace where shoppers can buy a range of diamond pieces from trusted wholesalers. This includes engagement rings, wedding bands, necklaces, and earrings, alongside loose diamonds. Their biggest selling point is that they can help shoppers save up to 40% on diamonds, thanks to their AI price and quality scores. Not only that, but all diamonds are reviewed by experts ahead of time, so you know that what you are getting is the real deal.
The brand is also worth raving about due to its commitment to customer satisfaction across the board. Currently, it boasts over 2,900 5-star reviews on Trustpilot and more than 3,400 on Google. This distinguishes it from other diamond brands on the market, especially when it comes to keeping their customers happy!
2. Blue Nile: The Best for Engagement Rings.
Getting ready to pop the question? Finding the right diamond (or ring, more generally) is no easy task. But it is one that is made a little easier by purchasing a product from Blue Nile. Considered to be the leader in artisan engagement rings, shoppers can browse a wide range of engagement rings on their site or stop by in person at one of their showrooms.
If you’re not a fan of any of the products that are already available, they also allow you to design your own engagement ring from scratch. This way, you can ensure you’re designing a ring that your partner will love, as their personality is reflected in every design feature, including the diamond itself.
3. Grown Brilliance: The Best For Lab-Grown Diamonds.
For several years now, lab-grown diamonds have been growing in popularity. As such, you do have a wide range of options to choose from if you are looking for diamond jewelry that is sustainably and ethically produced. One of the most popular bands operating within this niche is Grown Brilliance.
According to their website, Grown Brilliance diamonds are crafted by ‘skilled scientists and artisans who mimic the Earth's processes, creating the same carbon structure found in natural diamonds.’ This means that you’d find it difficult to differentiate between a lab-grown diamond and the ‘real’ thing (unless you’re an expert appraiser yourself).
4. Quince: The Best For Affordable Jewelry.
If you are shopping on a budget, then you may be able to find everything you need at Quince. While the online retailer stocks a wide variety of products, including clothing and homeware, they’re also known for their affordable jewelry range. For example, their diamond pieces start from as little as $75.
Their range is somewhat smaller than some of the other brands listed here, but there’s still a decent mix of traditional and modern designs to choose from. This means that finding a piece you like is relatively straightforward. Not only that, but they stock both traditional and lab-made diamond products.
5. Ritani: Best For Unique Pieces.
Whether you’re not a fan of the latest trends or find more traditional pieces to be a little boring, you’ll be pleased to hear that there are plenty of retailers that specialize in unique pieces, too. One of the leading retailers in this niche is Ritani.
Not only are their designs known for being a little quirkier than the average jewelry retailer's, but they also offer excellent customization services. This means that you can design your own ring, earrings, necklace, or bracelet through their online platform. They also allow customers to split the price of the jewelry over several smaller payments, making it much more affordable overall.
6. James Allen: Best For Pendants.
If you are in the market for a diamond pendant, then James Allen is a great retailer of choice. While it may seem as though their range is somewhat limited, with just 47 pendants available, they can be highly customized, meaning that the actual number of products available is far higher. For example, in addition to picking out the diamond itself, you also get to choose a complementary gemstone to wear alongside it.
7. Edge of Ember: Best For Day-to-Day Jewelry.
Diamond jewelry tends to be the kind of thing that we only pull out on special occasions. However, it does not have to be that way. The products available at Edge of Ember are simple and chic, meaning that they can be easily incorporated into your day-to-day outfits without looking out of place.
Another major selling point of this brand is the fact that they run regular discounts, which means that you don’t have to break the bank when discovering your next jewelry staples - whether that’s earrings or necklaces.
