Stephanie Gottlieb expands minimalist jewelry with lab-grown diamond lines

Stephanie Gottlieb is leaning into lab-grown diamonds with two lines that split the category cleanly between play and polish: Casual Carats, with 14k-gold rings on colorful silicone bands, and Lola, a drilled-diamond collection in 14k yellow or white gold. Gottlieb, who founded Stephanie Gottlieb Fine Jewelry in 2013, called lab-grown diamonds “for right now,” a line that captures how sharply her brand is recalibrating around the way clients actually wear jewelry.

Casual Carats is the more approachable of the two. The collection includes 20 rings, and the prices on Stephanie Gottlieb’s site run from $675 to $1,850. The settings pair lab-grown stones with 14k yellow gold inside silicone bands, which gives the pieces a distinctly less precious feel than a traditional ring mount. That makes sense for buyers who want diamond sparkle without the rigidity of a classic fine-jewelry silhouette. A round diamond version starts at $675, while pear and heart cuts push higher, a small reminder that shape still drives the fantasy even when the material has become more accessible.

Lola moves the same material into a more formal lane. The collection uses drilled lab-grown diamonds in 14k yellow or white gold, which gives it a sleeker, more jewelry-forward profile than the silicone-banded rings. The SG Fine Lola Lab Grown Drilled Diamond Necklace is priced at $4,065 and is made to order with a two- to four-week lead time. The Lola Lab Grown Drilled Diamond Shaker Ring costs $1,065, while the Lola Lab Grown Drilled Diamond Long Necklace reaches $7,750. If Casual Carats reads like an everyday indulgence, Lola is the version for buyers who still want the cleaner line and stronger finish of precious metal.

Gottlieb has said lab-grown diamonds open up “more room to play” and “more ways to wear diamonds,” and the timing fits a market in transition. De Beers’ 2025 Diamond Report examines how natural diamond demand differs from synthetic lab-grown stones, while McKinsey says the diamond industry is at an inflection point and has to adapt to changing customer preferences. One recent industry report put a 1-carat lab-grown diamond at about $1,000 or less in 2025, compared with around $4,200 for a natural 1-carat diamond. Another says two-thirds of Gen Z engagement ring purchasers choose lab-grown stones.

That is why Gottlieb’s new lines matter: Casual Carats suits the buyer who wants a low-stakes, high-visibility ring; Lola suits the customer who wants lab-grown diamonds in a more traditional precious-metal frame; and natural diamonds still belong to the buyer who wants the old language of permanence, rarity, and heirloom formality.
