To riff on Leo Tolstoy’s timeless adage: Happy women on holidays are all alike; each unhappy woman is disappointed you didn’t give her diamonds. Really. She may say she’s happy with that turquoise bauble or those silver hoops. Deep down, she’s disappointed diamonds aren’t involved.

Mined diamonds, however, aren’t exactly the most sustainable, ethical, or affordable piece of jewelry. Enter lab-grown diamonds from Clean Origin which, as company co-founder Alexander Weindling puts it, prioritizes people and the planet before profits.

“Our lab-grown diamonds are 100 percent diamond, but without the human tragedies or environmental destruction and pollution associated with mining,” says Weindling. “This also make them far less expensive than mined ones. A lot of marketers will tell you about their conflict-free mined diamonds, but the only 100 percent, conflict-free diamond is a lab-grown diamond.”

Clean Origin is the only major brand that sells exclusively lab-grown diamonds. Founded, owned, and run by jewelers, “the quality of our craftsmanship is unsurpassed,” Weindling adds. Here are our favorite, sparkling holiday gifts from the lab-grown diamond connoisseurs.

Classic Tapered Baguette Ring

Proposing? You can’t go wrong with a Clean Origin engagement ring. “Every Clean Origin diamond engagement ring is crafted one at a time to exacting standards,” says Weindling. “People, the planet, and quality are non-negotiable for Clean Origin.” This three-stone, tapered baguette ring dazzles in a classic, elegant display. Clean Origin’s selection of engagement rings may be customized according to your desired metal (14K white gold, 18K white gold, 14K yellow gold, 18K yellow gold, 14K rose gold, or platinum) and shape (round, cushion, pear, princess, oval, radiant, emerald, marquise, or asscher).
