Exploring the best places to buy lab diamond solitaire necklaces often comes down to more than finding a beautiful diamond. The retailer you choose can shape the entire experience, from comparing settings to feeling confident about the final purchase.
Most solitaire necklaces catch your eye for the same reason at first. However, the differences become much clearer once you start browsing a few retailers side by side. Some keep the process simple, while others require much more digging before the right piece appears.
Then there’s the question of value. A well-made solitaire necklace should pair a certified diamond with a secure setting and fair pricing. Just as importantly, the buying process should feel clear from start to finish.
To make that search easier, we’ve selected five retailers that stand out for different reasons. Whether you’re celebrating a milestone or buying an everyday piece, these are the best places to begin your search.
Our List of the Best Places to Buy Lab Diamond Solitaire Necklaces
A lab diamond solitaire necklace may look simple, but that’s exactly why every detail matters. With a solitaire necklace, there’s nowhere for the diamond to hide. A great stone stands out immediately, while a mediocre one does too. That’s why clear certification, strong cut quality, and realistic product images matter so much when comparing retailers.
It doesn’t take long to notice that some retailers simply make better use of your time. Finding the right diamond feels quick, the information is easy to trust, and getting answers never feels like a chore. Others ask you to do much more of the work yourself. Those differences shaped this list just as much as the necklaces did.

2. 1 Carat Lab Diamonds
Not every shopping trip needs thousands of options. Not everyone wants to sort through thousands of listings. 1 Carat Lab Diamonds, one of the best places to buy lab diamond solitaire necklaces, takes a more focused approach instead.
Lab-grown diamonds take center stage across the site, so browsing feels much more focused from the start. As a result, you’ll spend less time sorting through unrelated designs and more time comparing details like diamond quality, chain length, and metal.
You’ll come across plenty of classic solitaire necklaces without digging through page after page of products. Meanwhile, the smaller catalog keeps the search moving, especially when you already know the style you want.
Pros
- First of all, less time goes into scrolling, leaving more room to compare the solitaire necklaces that actually catch your eye.
- Meanwhile, the focus stays on lab-grown diamonds, so the collection feels consistent as you move from one necklace to the next.
- Additionally, classic solitaire styles are easy to spot throughout the collection, so finding an everyday design doesn’t require much searching.
- For someone making their first diamond purchase, the website feels simple to move through. The layout keeps the important choices clear without making the process feel complicated.
- Beyond the designs themselves, pricing stays competitive across many popular solitaire necklace styles, which adds another reason for shoppers to consider the collection.
Cons
- However, once you move beyond classic solitaire designs, the number of available options starts to shrink.
- At the same time, those searching for something outside the usual styles may run into fewer options to consider.
- As a result, anyone still deciding on a specific look may prefer a retailer with a wider range of designs.
3. Mark Broumand
Some solitaire necklaces are picked for everyday wear. Others are chosen because they feel like a special luxury purchase from the start. Mark Broumand shows up in this list of the best places to buy lab diamond solitaire necklaces. The pieces lean toward classic luxury, with carefully finished details and a style that feels more traditional than trend-driven.
Browsing Mark Broumand feels less like searching through a database and more like looking through a carefully chosen jewelry lineup. Each piece has a polished presentation, without the endless scrolling found on larger jewelry sites. The pieces stay centered on classic designs, refined finishes, and a polished overall look.
Because of that, Mark Broumand works best for shoppers who already have a clear idea of what they want. However, the luxury approach comes with a higher price point, and the collection offers fewer options compared with retailers built around larger inventories.
Pros
- These are the kind of necklaces that feel suited for a celebration, whether it’s a milestone gift or a special event.
- The craftsmanship becomes easier to appreciate when you look closer at the finishing and overall design.
- Because the selection stays smaller, browsing feels less crowded and keeps the attention on classic necklace styles.
Cons
- The main thing to keep in mind is the pricing. These pieces sit at a higher range, which may not fit every budget.
- That smaller selection also has a downside. Shoppers won’t find the same variety of designs available from larger online retailers.
- However, shoppers who like comparing many lab diamond options may reach the end of the collection faster than expected.
4. James Allen
Some shoppers enjoy taking their time before making a decision. That’s one reason James Allen remains one of the best places to buy lab diamond solitaire necklaces for anyone who likes comparing plenty of options.
The collection stretches across a wide range of solitaire necklace styles, diamond shapes, and price points. Meanwhile, detailed search filters make it easier to narrow the results once you know exactly what you’re after. You can also customize many necklaces by pairing different diamonds with your preferred setting and metal.
However, having more choices also means more comparing. After a while, many of the solitaire necklaces start looking very similar, which can slow the decision down.
Pros
- Meanwhile, the large inventory gives you plenty of solitaire necklaces to compare in one place.
- A few filters are usually enough to narrow the search by diamond shape, carat weight, metal, and budget instead of scrolling through endless results.
- If you decide to personalize the necklace, switching the diamond, setting, or metal feels straightforward, giving you plenty of flexibility before placing an order.
Cons
- However, browsing can become time-consuming once similar solitaire necklaces begin filling the search results.
- Meanwhile, shoppers who want expert guidance throughout the process may find themselves doing much of the research on their own.
- Without a clear plan, the sheer number of options can make the final decision harder.
5. Leibish & Co
Not every solitaire necklace follows the traditional white diamond route. Leibish & Co, one of the best places to buy lab diamond solitaire necklaces, takes a different direction by placing much of its attention on colored diamonds and fine jewelry.
From the first few pages, the collection heads in a different direction. Rather than filling the site with classic white solitaire necklaces, Leibish & Co gives far more space to colored diamond jewelry.
However, that distinctive approach won’t suit every shopper. Prices sit toward the higher end, and the selection of classic lab diamond solitaire necklaces feels more limited than retailers built around everyday diamond jewelry.
Pros
- Meanwhile, the collection stands out with distinctive colored diamond jewelry that isn’t easy to find elsewhere.
- The smaller collection gives each necklace a chance to stand out instead of getting lost among hundreds of similar designs.
- If you’re after something different, the designs offer an alternative to more traditional solitaire necklaces.

- At the same time, higher pricing can put many designs beyond everyday budgets.
- As a result, shoppers hoping to compare many white lab diamond necklaces may find fewer options than expected.
