Burst into 2021 and leave the past year behind you. All you have to do – slip on some of the new year’s trending styles to get you in the mood to totally own the next 12 months.

After the rollercoaster ride that was 2020, jewelry shopper preferences have turned to the classics: pieces that hold a timeless charm. The fine jewelry trends of 2021 are pieces that put diamonds front-and-center and are particularly popular. Why? They’re universally stylish. They won’t ever trend-out. And they make gifts that never fail to delight!
We can say with confidence that 2021 will be the year of the lab grown diamond. 30% more affordable than earth created diamonds, lab-grown diamonds are chemically and optically identical to traditionally mined diamonds. The only difference is that they’ve created, as you may have guessed, in a laboratory! Yes, and they are 100% pure diamonds.
How it’s done: scientists create these cutting-edge diamonds by first placing a tiny carbon “seed” in a specialized diamond-growing chamber. These chambers simulate the intense pressure and high heat conditions that facilitate diamond growth deep underground. As the heat and pressure work their magic, carbon vapor is gradually applied, microscopic layer by layer, onto the slowly growing diamond seed. After a few months, the lab-grown diamond is ready to be cut and polished! Thus the diamond creation process, which normally occurs on a geologic time scale, is sped up to take only a few months.
Growing a diamond in a lab uses minimal time and resources compared to mining an earth-created diamond, which is why it costs so much less to produce. Those savings are passed on to you, allowing you to nab an honest-to-goodness diamond for 30% less than you thought you could.
And now the best news of all: James Allen’s diamond studs and diamond pendants can all be set with lab-grown diamonds! Stick to your budget and still score the carat size of your dreams.
1. Diamond Rings
This just in: rings featuring small, glittering diamonds are trending in 2021. Diamond rings don’t always have to come in the form of wedding or engagement rings.

4. Diamond Earrings
Diamond stud earrings had a meteoric rise this past year. Even as the world hunkered down to weather the COVID pandemic, diamond earrings saw a steady increase in popularity. Why? Well, we have a few theories:
- They’re utterly wearable. They’re so lightweight that you can put them on, forget about them, and look fabulous the entire day without even trying. Even on Zoom.
- They suit any budget. The larger your budget, the more you can scale up your carat size. But even if your budget is relatively small, diamond studs afford you the most sparkle per dollar of any jewelry style.
- They’re excellent self-gifts. Got an important milestone you want to mark? Maybe a graduation, a big promotion at work, or a personal achievement you’re proud of? Celebrate yourself with diamond earrings.
