Valentine’s Day is February 14th, 2024, and jewelry is a popular Valentine’s Day gift, with Americans spending more than $5.5 billion on it each year. Popular options include heart-shaped jewelry, diamond necklaces, and diamond earrings.

Lab-grown diamond jewelry is perfect as a Valentine’s Day gift. Diamonds are ever-lasting and the most romantic of all jewelry. Lab-grown diamonds are much cheaper than mined diamonds, and you’ll save at least 60-80%. In addition, lab-grown diamonds are better for the environment and do not carry the negative impact that often follows the mining of diamonds, such as corruption and conflict.

Lab-grown diamond jewelry is the perfect gift for anyone you want to give something special for Valentine’s Day. And now, diamond jewelry is more affordable than ever before. Scroll down for our top picks for a stunning heart-shaped lab-grown diamond piece, just in time for Valentine’s Day. Whether it’s a dazzling pendant, elegant earrings, or a stunning ring, lab-grown diamonds are ethically crafted and offer a sustainable touch to your Valentine.

A solitaire diamond pendant is a great way to move focus to what matters – the diamond. This heart-shaped and stunning pink lab-grown diamond set in a pendant necklace from Clean Origin is all about romantic appeal.

And it comes at a very affordable price too. The 0.25 version costs $540, and the half-carat pendant is $760. The low prices are only possibly due to the significantly more affordable fancy-colored lab-grown diamonds (a mined equivalent would be 10-20x more expensive!)
