This holds especially true for those looking for the best Black Friday diamond necklace deals. A diamond necklace is not just a statement piece — it’s designed to be the star of your jewelry collection, one that effortlessly elevates your look and wraps your neckline in elegance and sophistication.

From handcrafted stunners like diamond tennis necklaces to intricately detailed small diamond necklaces, each piece carries more than just beauty — every purchase is backed by transparency, customer-focused policies, and expert guidance.

In this guide, you’ll find everything you need to shop smart this Black Friday and make the most of every dollar spent — from choosing the right diamond type to exploring the trending diamond necklace styles of the season. So, read on to discover how to make your Black Friday diamond necklace purchase both meaningful and rewarding.

1. Selecting The Perfect Diamond For Your Necklace

Whether you are buying a classic yet minimal 0.25-carat diamond solitaire necklace for everyday wear or a show-stopping platinum diamond necklace for special occasions, you need to choose a high-quality diamond so it can shine beautifully as it is meant to. This means you should invest only in certified diamonds that come with proof of quality and authenticity.

Here, we would like you to note that all our diamonds are sourced from the same trusted suppliers used by the biggest diamond jewelry brands in the United States and are certified by the industry’s top grading labs — GIA, IGI, or GCAL. Additionally, before a diamond is listed for sale, it undergoes a detailed two-step verification process, conducted entirely under camera, to confirm its origin, quality, and authenticity.

While certified natural diamonds remain the traditional choice, you can maximize your Black Friday savings by opting for certified lab grown diamonds. Chemically, physically, and optically identical to their natural counterparts, these sustainable and ethical alternatives are popular among conscious buyers for their affordability — typically priced at 1/3 to 1/4 of the cost of natural diamonds with the same 4Cs specifications.

Lab grown diamonds allow you to enjoy a rewarding and confident shopping experience without compromising on quality or exceeding your budget. With Rare Carat, your next lab diamond necklace purchase is guaranteed to be a value-for-money deal — and with up to 40% off on lab grown diamonds this Black Friday, there’s never been a better time to finally own your dream diamond necklace.

2. How To Choose The Right Setting Metal

While the diamond is the heart of a diamond necklace, the setting metal brings the entire design and aesthetic of the piece to life.

14K yellow gold diamond necklaces have long been the go-to choice for most buyers because of their timeless appeal and warm sophistication. However, this is not your only option.

Exploring all the popular metal types based on your lifestyle, budget, and personal preferences is highly recommended to ensure you’re choosing a diamond necklace that truly reflects your unique requirements, personality and style.

Take 14K white gold diamond necklaces, for example. They are a highly sought-after and affordable alternative to platinum settings, known for their ability to transform a traditional design into a sleek, modern look. Similarly, 14K rose gold diamond necklaces — often regarded as a symbol of love — are the perfect choice for those seeking a setting metal that feels both edgy and elegant.

3. Trending Diamond Necklaces To Shop For This Black Friday

Confused about which diamond necklace style will be the perfect choice for you? Or have you already decided and are simply looking for a bit more inspiration? Then take a look at the following trending diamond necklace styles that will never go out of fashion — admired for their beauty, versatility, and timeless practicality:

Solitaire Diamond Pendant Necklace:

In this minimalist style, the design is elevated by the presence of a single lab grown diamond — the true soul of the piece. That’s why choosing the right setting style and a compatible 14K gold metal is crucial to ensure the diamond is beautifully highlighted. For instance, a bezel set diamond necklace setting creates clean, modern lines that frame the diamond elegantly, while a hidden halo diamond necklace setting enhances the brilliance of the center stone. Similarly, a heart cut diamond brings a romantic touch, whereas an oval or cushion cut diamond adds a timeless, vintage charm to the solitaire pendant’s overall design.
