Online Diamond Store Reviews

Last Updated on 24th March 2025

Nowadays, everybody’s buying all kinds of stuff via the internet. Engagement Rings are no different!

Online shopping

If you want to buy diamonds online, you will find numerous websites offering their services.

Most likely, you’re not diamond-shopping on a regular basis, and so you might have no clue where to find them. Although most online vendors are legit, the question is if you’ll be able to make a good purchase. And this comes down to the quality of the online store and the kind of services they offer.


I have delved into most online diamond stores for you, so you can know what to expect from every single vendor. This post will introduce you to online diamond store reviews and eventually point you in the right direction – where her big “Yes” is!


What to Look Out for in an Online Diamond Store


Looking for the perfect diamond

The most important aspect you should be looking for is how much you get to see the diamond you are about to purchase.

Buying diamonds online offers huge price advantages, but these advantages are quickly set off if you don’t know what kind of gem you’ll be getting. After all, you can see the diamonds in person in a physical store.

For this reason, it is important that you get to view as much of the diamond as possible. Just knowing about the cut, carat weight, clarity, and color of the stone is not enough. It won’t give you an idea of what the diamond looks like. This issue is of particular importance to clarity grades but also, for example, to check whether an oval diamond exhibits a bowtie effect or not.

A superb diamond store shouldn’t just display a generic image or some animated picture of their gems. They should offer high definition photos from different angles or better yet, provide actual videos. This way, you can be sure that the vendor is not hiding anything from you!

You should easily be able to access a grading report; preferably one from either GIA or AGS. And there should be a customer service staff in place who can answer all of your questions instantaneously just as in an offline store.

At the moment, James Allen is the only vendor that offers high definition 360 ° videos of all the diamonds in their inventory, topped with an excellent customer service. See it for yourself!


Advantages of Buying Diamonds Online


Thinker

For one, online diamond stores don’t have to hold their inventory of diamonds. An online store can simply list a diamond from one of its suppliers and still provide you all the information that you need.

Plus, they don’t have to pay for fancy showrooms and sales force. This means massively reduced costs which can then be passed on to you. In fact, when comparing online and offline prices, you’ll see that offline vendors charge around 30% – 70% more for a diamond with the same 4Cs.

An online store can also offer you a greater variety of diamonds than an offline store. For rare fancy colored ones, you get to have some choices which you would hardly see in a regular shop.

For white diamonds, the selection might seem too many because of the phenomenon of the paradox of choice. Meaning, when we’re faced with too many options, we tend to be overwhelmed. However, good online shops exhibit filters, so that you can narrow down your search in a significant way!

Top online stores also display 20x magnified HD videos of their diamonds. This way, you get to see the diamonds even better than in a jewelry store where you would only have a 10x loupe.

Another advantage is that there is no salesperson subtly pressuring you into buying a diamond. I used to be a salesperson in a brick and mortar store, so I should know what I am talking about. 🙂
