Stephanie Gottlieb debuts lab-grown diamond collections for everyday wear
Stephanie Gottlieb's new lab-grown capsules, Casual Carats and Lola, turn a once-rejected category into silicone-band rings, drilled necklaces and a clear price ladder.
Stephanie Gottlieb has launched two lab-grown diamond capsule collections, Casual Carats and Lola, after previously saying she would never sell the stones. The move lands as lab-grown prices have fallen sharply, giving her a way to sell everything from a $675 ring to a $7,750 necklace for buyers who want diamond jewelry without the milestone-only rigidity of the natural category.
Casual Carats is the more playful of the two. The line pairs lab-grown diamonds with 14-karat yellow gold on silicone bands in black, pink, red, green, white, coffee, neon orange, orchid, regal blue, powder blue, cerulean and Sakura pink. Styles currently listed on Gottlieb’s site include a round ring at $675, a heart ring at $895, a pear-cut ring at $975 and an emerald-cut ring at $1,850. The silhouette is low-commitment and easy to wear, closer to fashion jewelry than engagement-ring theater.
Lola moves the idea into drilled diamond jewelry, with a shaker ring priced at $1,065, a double-wrap necklace at $7,750, plus linear and graduated drop earrings, a tennis necklace, a pear-and-round station necklace and threader earrings. These are pieces built for layering and repeat wear, not just for a proposal box or a safe deposit drawer. The collection also shows how lab-grown diamonds are being used to expand the product mix, not simply to offer a cheaper version of the same thing.
Gottlieb’s change of course is notable because her earlier position was the opposite. In 2024, she was still being described as loyal to natural diamonds while navigating the rise of lab-grown options. Now she says lab-grown has “earned its place,” while natural diamonds remain the “forever investment.” She has also said lab-grown is a strong fit for travel jewelry, everyday diamonds and “the fun in-between moments.”
That shift tracks with the market. Recent reporting has put wholesale lab-grown diamond prices down 90% to 95% from 2015 levels, while retail prices fell roughly 60% to 70% between 2020 and 2024. McKinsey has described the diamond business as being at an inflection point as lab-grown stones gain share. Gottlieb’s two capsules show where the category is finding traction: casual, fashion-led, lower-commitment luxury, with price points and styling that suggest lab-grown is being repositioned as a wear-every-day material rather than only a substitute for bridal buying.
