Best Black Friday Diamond Deals For 2025

Finding the best deal on Black Friday is now a major trend — and for good reason. But when it comes to buying diamonds during Black Friday sales, shoppers need more than just discounts. They need trust, quality, and confidence in what they’re purchasing. After all, diamond jewelry isn’t just another item to purchase; it’s a statement piece of lasting value, timeless appeal, and often tied to life’s most meaningful moments.

Rare Carat blends competitive Black Friday pricing with uncompromising standards of authenticity and quality, making it the go-to destination for all things diamond. From certified natural and lab grown diamonds to handcrafted settings and fine jewelry, every purchase is backed by transparency, expert guidance, and customer-first policies.

In this guide, you’ll discover everything you need to shop smart this Black Friday — from finding the perfect diamond using Rare Carat’s filters and gemologist advice, to understanding reviews, warranties, and why Rare Carat continues to be the most trusted place to buy diamond jewelry in 2025.

1. Rare Carat's Diamonds: What to Know Before Buying

Natural diamonds are rare treasures, formed over billions of years. Each carries a piece of history and tradition. However, mining natural diamonds is placing a strain on the planet, which is why the industry has seen a significant shift with the rise of lab grown diamonds — a sustainable and equally stunning alternative.

An understanding of the difference between natural and lab grown diamonds will explain why both the diamonds share the same physical, chemical, and optical properties.

Lab grown diamonds are especially popular among modern, conscious buyers because they not only provide an ethical choice but also come at a fraction of the price — often 1/3 to 1/4 of the cost of a natural diamond with the same specifications.

This price advantage becomes even more appealing during Black Friday, when Rare Carat’s exclusive deals can help you maximize value. For instance, the price comparison chart below showcases diamonds with identical 4Cs specifications — G color, round shape, excellent cut, and VS2 clarity — across both natural and lab grown options, highlighting how much more you can save when shopping smart this season:

With Rare Carat, you can easily choose between natural and lab grown diamonds right from the outset, ensuring you find the perfect match for your jewelry — and lock in the best possible Black Friday deal.

Whether natural or lab grown, Rare Carat ensures every diamond is authentic and certified by one of the industry’s top grading labs: GIA, IGI, or GCAL. All certified diamonds are sourced exclusively from a carefully vetted network of trusted suppliers — the very same suppliers used by some of the largest and most respected diamond jewelry brands in the United States.

2. Commitment to Quality & Authenticity

Once a diamond is sourced and sent to the Rare Carat facility, it undergoes a diligent two-step verification process as part of Rare Carat’s strict quality framework.

To ensure a fully transparent and trustworthy shopping experience, these inspections — focused on both quality and authenticity — are conducted entirely under camera. To our knowledge, Rare Carat is the only online jewelry brand that documents this entire process on video, offering customers a rare glimpse into the rigorous standards behind every diamond of their choosing.

3. How to Find the Perfect Deal on Black Friday

At Rare Carat, you can enjoy discounts of up to 40% off this Black Friday (only on lab grown diamonds and jewelry). But whether you shop during the holiday sale or not, Rare Carat ensures you find a diamond that aligns with your budget, preferences, and requirements — all without compromising on quality.

If you’re planning to buy a diamond this holiday season, you already know how crucial it is to understand the 4Cs (Cut, Color, Clarity, and Carat weight). The 4Cs are not only essential for identifying your ideal diamond but also form the basis of every diamond’s certification. To help shoppers apply their preferred specifications with ease, Rare Carat’s advanced diamond search filters are designed around these exact criteria. Here’s what you can expect when browsing for the perfect loose diamond:
