When Jenny King-Modlin acquired engaged two years in the past, her companion slipped a 1.3-carat diamond ring on to her finger to indicate his love for her.
However in contrast to the bridal rings which have dominated the worldwide marketplace for many years, hers was manufactured in a manufacturing facility reasonably than dug out of the bottom — and one-third cheaper.
“To me, it appears like a diamond, it sparkles like a diamond and makes me really feel like I’m sporting a diamond,” says the 36-year-old author and actor, who lives in New York. “It wasn’t simply an moral resolution, it was monetary, and we fell in love with that actual ring.”
She will not be alone. Thousands and thousands are opting to purchase jewelry encrusted with artificial diamonds, which not solely have the same composition to pure diamonds but additionally typically have fewer defects, making them seem extra radiant.
The increase in demand for synthetics is starting to radically reshape the $89bn world diamond jewelry market.
The market share held by these man-made stones has surged from 3.5 per cent in 2018 to a forecast 16.5 per cent — equal to $14.6bn — in 2023, in line with Paul Zimnisky, an impartial analyst who collates diamond transaction knowledge from retail market costs. As compared, pure diamond gross sales in greenback phrases have been flat since 2015.
“The function of a mined diamond will likely be a distinct segment product. Why pay an element [more] for an atomically similar product?” mentioned Martin Roscheisen, chief govt of Diamond Foundry, whose output of synthetics makes it the equal to one of many world’s prime 5 largest diamond mines.
Costs for a refined 1-carat pure stone have slumped by greater than 1 / 4 since their 2022 peak to $5,185, in line with Ziminsky, the bottom stage in eight years as they face a recent supply of competitors.
However costs for synthetics have fallen even additional, from greater than $5,000 per 1-carat polished stone in 2016 to $1,425, Ziminsky has discovered. That has been pushed by suppliers’ rush into the booming market, outstripping jewelry consumers’ wishes, and by economies of scale bringing down prices.

The diverging reputation of pure and so-called “lab-grown” stones has been laid naked this month.
Pandora, the world’s largest jewelry retailer by gadgets offered, raised full-year steering and mentioned it could develop additional in its fastest-growing phase — lab-grown diamonds.
“In 2010, I might’ve been hesitant to enter this market resulting from a scarcity of shopper consciousness,” Pandora chief govt Alexander Lacik advised the Monetary Instances. “Quick-forward 10-plus years and 60 to 70 per cent of all shoppers are conscious that there are lab-grown diamonds.”
Canadian miner Lucara Diamond, in the meantime, mentioned it could substitute chief govt Eira Thomas. That got here after it mentioned there was “doubt relating to [its] means to fulfill its commitments”, as price overruns for an underground growth at its Karowe mine in Botswana have been compounded by macroeconomic gloom and the rising reputation of artificial stones.
The primary non-natural diamonds had been made by Basic Electrical in 1954 for business makes use of reminiscent of scalpels, however lately expertise has made mass manufacturing cheaper. On the identical time shoppers have turn into extra aware of the perceived monetary and moral price of mining pure stones.
Some within the trade hope the burgeoning demand for lab-grown diamonds will stimulate a want for the unique variations, solid by intense strain and warmth billions of years in the past.
“The optimistic for the pure enterprise is that there’s an entry-level merchandise that many extra can afford,” mentioned Edahn Golan, managing companion of Tenoris, a diamonds analytics firm. The hope is that buyers “graduate” to pure diamonds, he added.
However shoppers like King-Modlin fear about working circumstances at mines and tout the decrease carbon emissions that accompany lab-grown diamonds. Miners refute each factors, saying they make use of hundreds of individuals in impoverished areas whereas artificial stone manufacturing in India and China is powered by coal.
There seems to be no let up in lab-grown diamond gross sales. Exports of polished synthetics from India, the world’s largest diamond cutter and polisher, rocketed to $1.7bn between April 2022 and March 2023, up 28 per cent in contrast with the earlier monetary yr, in line with India’s Gem and Jewelry Export Promotion Council (GJEPC).
Diamond Foundry is planning to double manufacturing within the subsequent three years. Even diamond mining trade chief De Beers launched its personal artificial gem engagement ring in June.
Against this, India’s far bigger reduce and polished pure diamond exports dipped eight per cent in the identical interval, to $22bn.
“The unhealthy information for the diamond trade is there’s a sure factor of cannibalisation. It’s happening in engagement rings,” mentioned Golan.

However fears are additionally rising that the worth crash in synthetics will unleash bankruptcies throughout artificial producers and jewelry retailers.
“The underlying concern is that we’re strolling in direction of a massacre in lab-grown diamonds,” mentioned Richard Chetwode, managing director of RCC Diamond Consultants.
Al Cook dinner, chief govt of De Beers, the world’s largest diamond producer by worth, mentioned there can be short-term ache, when it comes to decrease profitability, from the push to artificial diamonds however the aggressive menace would abate.
“The stronger the forest hearth burns, the sooner it burns itself out. The method of burning feels highly regarded,” he mentioned.
Some within the diamond trade argue {that a} turning level has already been reached as retailers not see man-made stones as a high-margin enterprise however as a lossmaking one, as a result of the inventory is depreciating too quickly to make a return.
David Kellie, chief govt of the Pure Diamond Council, a foyer group, says that buyers see mined diamonds in the same technique to how Swiss watches got here to be considered when confronted with the specter of Apple Watches and Fitbits.
“Folks don’t purchase Swiss watches to inform the time,” he mentioned. “Apple most likely sells extra watches than the complete Swiss watch trade however does that matter in the event that they’ve grown throughout that interval?”
With seemingly unstoppable momentum on the availability of artificial diamonds, Zimnisky says that there will likely be a “shakeout” amongst lab-grown producers.
“By and huge, I believe the market went from new, novel and thrilling to grossly oversupplied,” he mentioned.
Vipul Shah, GJEPC’s chair, believes that each gem sorts can coexist however competitors, he mentioned, is fiercest between the lab-grown diamond makers themselves.
“Whoever will not be in a position to be aggressive within the value [ . . . ] they are going to be out of the enterprise. That’s what’s occurring presently.”
Some lab-grown gamers are sanguine concerning the shakeout. Vishal Mehta, founder and chief govt of Dubai-headquartered lab-grown diamond dealer Lumex, agrees there’s a important overstock of the gems, with the low costs hurting producers who’re debt-financed. However he forecasts that the market will regulate.
“You’re discovering the environment friendly value that may work for the shoppers, retailers and growers,” Mehta mentioned. “I believe we’ll overshoot it a bit, which is what occurs with new applied sciences.”
In the meantime the posh finish of the market is making an attempt to remain optimistic.
One jeweller consumer of Mehta’s lately crafted a necklace for a Gulf royal utilizing $8mn-worth of mined diamonds, however set the uncommon gems amongst $100,000 price of lab-grown sparklers. The jeweller advised him: “I take a look at lab-grown diamonds just like the body on an Andy Warhol.”
