Grown Brilliance and Shreya Mehta turn lab-grown diamonds into celestial art

Grown Brilliance is asking a simple but pointed question: what happens when a diamond stops being jewelry and becomes art? The answer, in the brand’s new collaboration with multimedia artist Shreya Mehta, is 12 celestial-themed paintings lit with lab-grown diamond dust, works that trade the usual ring-box symbolism for something meant to hang, collect, and live in a home.

The project, called “Diamond Nebula,” leans hard into the emotional language that sells fine jewelry in the first place. Celestial forms and shifting constellations give the paintings a cosmic vocabulary, while the diamond dust ties them back to the material promise at the center of the brand. Grown Brilliance plans to reveal the works at an event with Make-A-Wish New York, and the 12 paintings were slated to be auctioned Wednesday, turning a decorative object into a fundraiser and a collectible at once.

The timing is sharp. WWD noted the collaboration against the backdrop of Artemis II completing its lunar flyby and splashdown, and founder Akshie Jhaveri said she had an “inkling” NASA was preparing for a blast-off. That connection matters because the collection is not just borrowing stars as a motif. It is using space as a shorthand for aspiration, discovery, and the kind of personal meaning buyers often seek when they choose a diamond in the first place. In this case, the symbolism moves beyond the wrist, neck, or finger and into the room itself.

That broader strategy fits Jhaveri’s positioning of Grown Brilliance as a female-founded, ethical lab-grown diamond house. Founded in 2021 by the third-generation jeweler, the brand has previously said its supply chain and packaging are carbon-neutral through offsets purchased from the United Nations carbon offset platform, and that 95% of its diamonds are I+ in color and VS2 or higher in clarity. Those details matter because lab-grown luxury still lives or dies on trust: provenance, grade, and whether sustainability claims are specific or just polished language. Here, the brand is trying to make the ethical case visible as well as verbal.

It is also a business bet on where the category is heading. WWD has previously reported Grown Brilliance’s high-jewelry prices ranging from $12,000 to $270,000, and the wider lab-grown market has momentum, with 53% of U.S. consumers saying they would choose a lab-grown diamond over a mined one in a September 2023 MVI Marketing report. In that light, “Diamond Nebula” is not just decorative crossover. It is a bid to turn diamond symbolism into a lifestyle language that can travel from the body to the wall without losing its charge.
