Now, let's see how we make this happen:

1. Natural vs. Lab Diamond Pendants: What’s the Difference?

Just a few years ago, diamond shopping meant only natural diamonds created by the earth over a billion years ago, known for their rarity and beauty. But things are different now. Modern buyers have shifted their interest towards lab-created stunners as their go-to diamond choice.

Even though lab diamonds are created artificially, they possess the same physical, chemical, and optical properties, making them virtually indistinguishable from mined stones.

A glance at the differences between the two types reveals that, other than their origin, the price is the major difference. Due to its high-tech production process and excess availability, lab stones will be ⅓ to ¼ the price of their natural counterpart with the same 4Cs specifications.

Here’s how natural and lab-grown diamond pendants typically compare in price:

Pendant Type (Solitaire) Natural Diamond (Est.) Lab-Grown Diamond (Est.) Estimated Savings
0.50 ct. Solitaire Pendant $900 – $1,800 $300 – $650 ~60–70% less
1.00 ct. Solitaire Pendant $3,000 – $5,500 $1,000 – $2,000 ~65–75% less
2.00 ct. Solitaire Pendant $10,000 – $18,000+ $3,500 – $7,000 ~70–80% less

Note: Price estimates reflect common market ranges for comparable diamond quality and metal type. Final pricing varies based on cut, color, clarity, and setting style.

Because of this obvious price difference and similarity in look and durability, lab stones are becoming the popular choice, and buyers are looking for an extensive collection that can satisfy their search for the perfect diamond for the pendant.

Whether you are interested in pendants or engagement rings, at Rare Carat, you will find the choice to shop between the two diamond types from the get-go. This is done to ensure a quick and seamless shopping experience when browsing our collection—the largest of any jeweler in the USA—with over 2,500 fine jewelry designs.

2. The Right Diamond for Your Pendant

From our powerful recommendation engine to our detailed educational blogs and high-resolution diamond imagery and 360° videos, the Rare Carat website is the place to shop confidently for lab-created diamond pendants. Irrespective of the diamond or style you pick from our vast collection, all diamonds, whether natural or lab, will come with a grading certificate from only distinguished institutions, such as GIA, IGI, or GCAL.

We know that nowadays offering only certified diamonds doesn't prove the stone's ethical origin, authenticity, or overall worth. And for this reason, we conduct an additional two-step verification process free of charge for each diamond before it is shipped to the customer or to our advanced workshops in New York and New Jersey for excellent handcrafted pendants. This process includes:

  • A laser inscription inspection process using 60x to 110x magnification. For maximum transparency and accuracy, if something doesn’t meet any one of our strict standards, the stone is sent back for the required correction or resolution before customers can view it on our site.

  • An authenticity testing process using professional-grade UV fluorescence machines. Even if you choose a rare diamond (for example, Type IIa), we will take extra steps (Yehuda machine test) to ensure you are getting a stone that is exactly what it claims to be.

As the 4Cs are considered the parameters for successful diamond buying and certification checks, our diamond search filters are designed accordingly to ensure that finding and comparing diamonds is as straightforward and informative as possible. You can search for a lab stone for your pendant by setting trade-offs, such as the diamond’s:

This ensures you can select a diamond that truly aligns with all your preferences and requirements every time.
