As the diamond is the “star” of this necklace, buyers always seek a trusted retailer that provides a smooth, rewarding, and supportive diamond shopping experience.

Buyers can always expect clear pricing and a wide selection of only certified diamonds, whether they prefer lab-grown or natural diamond necklaces.
Let’s discover how our online shopping experience stands out.
1. Natural vs. Lab: Making the Right Decision is Simple
At first, lab-grown stones gained traction in the diamond jewelry market because they were an excellent, ethical, sustainable, and eco-friendly alternative. However, as more people began to understand that both types share the same physical, chemical, and optical properties, choosing lab-created diamonds for solitaire necklaces has become the norm.
They are now the favorite of most conscious, smart buyers because they are much more affordable than their natural counterparts in the same 4Cs specifications. This means a lab-created diamond in a specific cut, color, clarity, and carat grade will cost ⅓ to ¼ the price of a mined diamond having the same 4Cs specifications. As a result, most buyers can go for a bigger or better option than first intended without overstepping their budget or compromising durability and brilliance.
Here is a general price comparison chart to help illustrate the difference in cost between lab-grown and natural solitaire necklaces, based on commonly selected cut, carat, color, and clarity grades:
| Solitaire Necklace (Round Cut) | Natural Diamond (Est.) | Lab-Grown Diamond (Est.) | Estimated Savings |
|---|---|---|---|
| 0.25 ct Solitaire Necklace | $600 – $1,200 | $200 – $450 | ~60–65% less |
| 0.50 ct Solitaire Necklace | $1,500 – $2,800 | $450 – $900 | ~65–70% less |
| 1.00 ct Solitaire Necklace | $3,500 – $6,000 | $1,200 – $2,200 | ~65–75% less |
| 2.00 ct Solitaire Necklace | $11,000 – $18,000+ | $4,000 – $7,500 | ~70–80% less |
Note: Price estimates represent typical market ranges for comparable diamond quality and metal type. Final prices may vary depending on the diamond’s cut, color, clarity, and the necklace setting.
Rare Carat offers 1,700+ ring styles and 2,500+ fine jewelry designs, each available in multiple precious metals—making it one of the largest collections offered by any jeweler in the U.S. However, with our website’s search filters and recommendation engine, the collection feels extensive without being overwhelming.
Finding exactly the style you want for the solitaire necklace or pendant will be easy from the get-go, as at Rare Carat, you can choose between the two as soon as you start. This will narrow down your search process and make it more tailored to your preferences, requirements, and budget.
Our diamond search filters can further assist with the diamond search process, as they are designed with the diamond shape, 4Cs parameters (Cut, Color, Clarity, and Carat), and price. This ensures that finding and comparing diamonds is always transparent and informative with Rare Carat.
2. Best Quality, Certified Lab Diamonds for Your Solitaire
At Rare Carat, all diamonds (both lab and mined) are certified to offer a transparent pricing and shopping model. To ensure the sourcing process is ethical and successful, we only accept certificates from the very best institutions in the industry, such as GIA, IGI, and GCAL. With our free diamond report and certification checks, buyers can easily evaluate the stone for their solitaire, making the search process further effective and reliable.
Beyond ensuring every diamond is certified, we conduct our very own verification and inspection process to ensure every aspect of the diamond’s quality matches what is provided in its certification. This is also done to prove the diamond’s authenticity for our customers. This two-step verification process includes an inception test of the diamond’s laser inscription using professional 60x-110x magnification.
We understand how important this is, and that’s why Rare Carat performs this for every diamond before it is shipped to our customers or is sent to our advanced workshops in New York and New Jersey for handcrafting the necklace.
If even the slightest issue or discrepancy is found, the diamond will be sent back for correction and again checked following our two-step verification process once it arrives at our facility the second time.
In addition to laser-inspection verification, we conduct an authenticity test using only professional-grade UV fluorescence machines. And for rarer diamonds, a Yehuda test. As far as we know, Rare Carat is the only brand that performs such quality and authenticity checks under a camera for complete transparency.
3. Creating the Vibe with Seamless Customization
When we consider engagement ring designs, the style that comes to mind first is a stunning solitaire ring. The same goes for diamond necklaces.
Solitaire style has been popular for ages, as it is a design that has stood the test of time, thanks to its effortless, timeless beauty. For this reason, when buyers are looking for diamond necklaces, especially first-time buyers, a solitaire design is always the go-to choice or at least the first style they look into.
The beauty of a solitaire lies in its capability of blending with the wearer’s style and personality. This is also why they are considered an essential piece in all jewelry collections. The simple design offers maximum room for customization, ensuring the necklace is truly the best fit for you and aligns with all your requirements and budget.
By Diamond Shape
The round diamond cut is the most popular choice, and finding the perfect one is easy. However, it is not the only choice. Just changing the shape from round to a shape of your choice, you can bring a new twist to this iconic design.
At Rare Carat, you will find that most lab-created diamond solitaire necklaces come with the option to customize the diamond shape. With just a few clicks, you can check out all options and see how that particular solitaire design looks with your preferred shape, or a shape you are interested in.
