The 10 Best Online Diamond Stores

The number of online diamond stores has increased exponentially over the past few years. However, knowing which one is the best option for what you are looking for can take a lot of browsing. To save time, we have assembled a list of the 10 best diamond stores online to help you decide which one fits your needs and style without having to visit each one.

The Best Online Diamond Store

Blue NileBlue Nile

Blue Nile is acknowledged for being pioneers in the online diamond business since 1999. They were the first company in the world to sell diamonds on the internet. Over the years, they’ve built the largest selection of diamonds of all the sites, and it’s the company with the most sizable turnover. However, Blue Nile has been decreasing in power, and it’s losing rising market shares because most customers are not willing to purchase diamonds blindly anymore.

For people who live in the UK or Europe, Blue Nile offers an unmatched level of service and the best territorial outreach compared to other stores. They ship to almost every nation in the European Union (even to the smaller countries like Luxembourg). If you are based in the UK or Europe and don’t want to deal with the hassle of paying (VAT) Value Added Tax when buying from a US-based store, Blue Nile would be ideal for you. However, if you’re elsewhere in the world, then you might be better served by another online diamond store.

James AllenJames Allen

This one has to be included without question. James Allen has been beloved for years by costumers, and naturally, they are one of the industry leaders. The customer service they provide is fantastic, and they give you all the fundamental tools to buy a diamond online.

The key to their success has been bringing high-quality videos to the online consumer to show exactly what they’ll get. This is an excellent way to make you feel safer and more confident about your purchase. Apart from their video technology and outstanding customer service, they also have a broad selection of masterfully crafted settings and exceptional prices. This is why we consider this store deserving of being at the top of our list. Many people purchase from James Allen every month and give them rave reviews after their experience.

Despite their competitors catching up a little in terms of the technology side, James Allen still leads with the best videos out there. This is especially useful when you want to study the different cuts available to you. Given James Allen’s growth in stature, they’ve managed to partner with some fanciful designers, too. That has allowed them to add some really beautiful rings from designers like Verragio and Danhov. Thanks to this, you can be assured that no matter how fancy your style is, you’ll find something that you like here.

Brian GavinBrian Gavin

Brian Gavin, who founded Brian Gavin Diamonds, comes from a family of diamond cutters from South Africa. He was one of the most notable and major influencers in developing Hearts and Arrows Diamonds. The diamond cutter has fully committed himself to marketing only diamonds with the best and most memorable cuts that you can imagine. Brian Gavin has lived up to his commitment by producing Black lines, which have been quite popular for a while. If you are mega-focused on cut and searching for a truly spectacular diamond in terms of brilliance, Brian Gavin Diamonds is the way to go.

Their customer service equals the quality of their products. This is a premium store reputed for remarkably high-quality craftsmanship, which is 100% justified. However, as it’s a premium store, it’s not for everyone. Most people prefer to go for bigger diamonds, which means sacrificing a bit on cut. But if you value brilliance over size, Brian Gavin is the store you should visit.

Color diamonds are not an easy thing to get right, but this company has a certified legacy on this front. Leibish is the best at this. Period.

People who have purchased diamonds and jewelry from Leibish have been ecstatic with the result. They have an amazing selection of diamonds.
