Looking for the best places to buy diamond solitaire necklaces? One thing quickly becomes obvious once you start comparing them.
With a solitaire necklace, there’s nowhere for the diamond to hide.
One stone does all the work, so its cut, sparkle, and overall quality naturally draw the most attention. That’s also why two necklaces that look almost identical at first can feel entirely different once you look a little closer.
Meanwhile, the retailer behind the necklace matters just as much. Diamond quality, certifications, pricing, and the guidance you receive all shape the experience long before you place an order.
So, before putting this list together, we looked beyond the product photos. We compared the diamonds, overall value, shopping experience, customer support, and pricing transparency to find the retailers that consistently stood out.
Our List of the Best Places to Buy Diamond Solitaire Necklaces
A solitaire necklace doesn’t leave much to the imagination. Since only one diamond takes center stage, its quality becomes the first thing most buyers notice.
That also changes how you compare retailers. Instead of focusing only on the setting, it’s worth paying close attention to the diamond, the certification, and the value you’re getting.
With that in mind, we compared the best places to buy diamond solitaire necklaces using more than appearance alone.
So, we spent more time looking at the diamond than anything else. With a solitaire necklace, one diamond makes the biggest impression. So we focused on the quality of that stone first.
Of course, the diamond isn’t the only thing that matters. Pricing, certifications, customer support, and the buying experience all played a part as well.
The comparison below gives you a quick snapshot before we look at each retailer in more detail.
A Quick Comparison of the Best Places to Buy Diamond Solitaire Necklaces
| Retailer | Best For | Why It Stands Out |
| Rare Carat | Overall value | Certified diamonds, transparent pricing, expert guidance, and extensive customization |
| 1 Carat Lab Diamonds | Focused shopping | One-carat specialization with a simple, easy-to-browse collection |

1. Rare Carat – Overall Best Place to Buy Diamond Solitaire Necklaces
A solitaire necklace may look simple, but the diamond does almost all the work.
With only one stone taking center stage, its cut, clarity, color, and sparkle become much easier to notice. That’s why the retailer you choose is just as important as the necklace you select.
Rare Carat stands out as one of the best places to buy diamond solitaire necklaces because the experience stays focused on helping buyers make informed decisions from start to finish.
Unlike many retailers, Rare Carat operates as both a direct-to-consumer and a merchant-of-record diamond jewelry retailer. That keeps the buying experience consistent from start to finish. After checkout, buyers stay with the same seller, making the process much more consistent from selection to delivery.
Meanwhile, operating without traditional showrooms helps keep costs lower. As a result, comparable diamond solitaire necklaces are often priced well below what buyers typically find through many local or online jewelers.
If you’re still comparing the best places to buy diamond solitaire necklaces, give this detailed guide a read to see why Rare Carat continues to be one of the most trusted names in diamond jewelry.
More on the Brand
Finding the right solitaire necklace starts with finding the right diamond.
Rare Carat gives buyers access to more than 1.5 million natural and lab-grown diamonds, all certified by GIA, IGI, or GCAL. That makes it much easier to match the right stone with the right solitaire setting instead of settling for a limited selection.
However, choosing a diamond is not always easy. When you’re shopping for a diamond for the first time, it can be confusing to understand the 4Cs, read grading reports, and determine if a diamond is a good value.
Fortunately, that’s where Rare Carat separates itself from many retailers. More than 100 GIA-certified gemologists are available whenever buyers need help. Just as importantly, they work as consumer advocates rather than commissioned salespeople, so the advice stays honest, unbiased, and focused on finding the right diamond instead of making a sale.
Meanwhile, advanced filters, the Rare Carat Report, and quality and price scores do much of the heavy lifting. That leaves buyers with fewer diamonds to sort through and more confidence in the final choice.

Final Thoughts on the Best Places to Buy Diamond Solitaire Necklaces
A solitaire necklace asks more from a diamond than almost any other necklace style. With only one stone on display, every detail becomes part of the finished piece. That’s exactly why taking a little extra time before buying usually pays off.
No two retailers approach that experience the same way. Some give you more designs to browse. Others keep the process simple or focus on traditional craftsmanship. Every buyer approaches the search a little differently, so the right retailer isn’t always the same for everyone.
Still, Rare Carat continues to stand out as the strongest all-around choice for many buyers.
The experience starts with certified natural and lab-grown diamonds. From there, buyers can personalize the necklace without feeling boxed into standard options.
More than 100 GIA-certified gemologists are also available to answer questions whenever guidance is needed. As a result, choosing a single diamond feels much more confident from the very beginning.
A diamond solitaire necklace often becomes something you’ll wear for years, not just for one occasion. Finding the best places to buy diamond solitaire necklaces is really about choosing a retailer that helps you feel just as confident after the purchase as you did before it.
