Alrosa Sees First Glimmers Of A Turnaround Driven By Growing Scarcity
Supply Crunch In Larger Stones Lifts Rough Diamond Prices
Russian diamond giant Alrosa is detecting the first glimmers of a turnaround in both rough and polished diamond markets after several tough years, driven by growing scarcity as global production heads toward its lowest level in two decades.
The miner reported that prices for its rough diamonds have climbed 6% to 9% since the start of 2026, with the most pronounced gains in the high-value 2- to 10-carat segment. That category accounts for about 80% of Alrosa’s production by value. Prices in these sizes rose across all three of the company’s trading sessions this year, with modest improvement in January followed by stronger advances in February and March. Overall, Alrosa lifted selling prices to varying degrees on nearly half of its regular assortment in the first quarter.
Alrosa forecasts that worldwide diamond output will drop below 100 million carats in 2026—the lowest in 20 years—with risks of even steeper declines as older deposits are exhausted and unprofitable mines are idled.
The company itself has already suspended operations at several smaller sites, including alluvial projects in the Anabar River Valley and the Verkhne Munskoye deposit’s Zapolyarny and Magnitny open pits. Rio Tinto’s Diavik mine in Canada, a long-time supplier of high-quality stones, reached the end of its commercial production this week after more than 23 years and over 150 million carats extracted. Other Canadian deposits are also slated for permanent closure this year.
The tightening supply comes as major producers, including Alrosa, have deliberately curtailed output in recent years to help balance inventories. Alrosa itself plans to mine 25–26 million carats in 2026, down from higher levels, while continuing to sell into key markets such as India and China despite Western sanctions.

Pandora Adds Carbon Footprint Labelling For LGDs
New Level Of Transparency Empowers Consumers To Compare Climate Impact Of Their Diamond Jewellery
For decades, diamonds have been graded by the traditional 4Cs: Cut, Colour, Clarity and Carat. Now Pandora is adding the 5th C, declaring the carbon footprint of every Pandora Lab-Grown Diamond as part of the product information on pandora.net alongside the traditional four grading criteria.
The carbon footprint covers all emissions from the diamond crafting process: from producing the raw materials used to grow the diamond all the way until it is cut and polished, ready to leave the diamond facility.
As an example, a one carat Pandora Lab-Grown Diamond has 12.58 kg of CO2e emissions. This is around 90% lower than a mined diamond of the same size.
By adding carbon footprint to the diamond conversation, Pandora gives customers an extra point of comparison and essential insight into the climate impact of their desired diamond jewellery.
CARBON FOOTPRINT COMPARABLE TO A PAIR OF JEANS
Lab-grown diamonds are chemically, optically, thermally and physically identical to mined diamonds.
Pandora stopped using mined diamonds in 2021 and is now only using lab-grown diamonds made with 100% renewable electricity and set in jewellery crafted from 100% recycled silver and gold.This significantly reduces the carbon footprint of the Pandora Lab-Grown Diamonds collection. For example, a 14k gold Pandora Infinite ring with a 1 carat lab-grown diamond has a comparable carbon footprint to a pair of jeans.
PANDORA TO SHARE FINDINGS
The carbon footprints of Pandora’s lab-grown diamonds have been calculated by external life-cycle assessment experts and published in a study verified by auditing firm EY. The study uses best practice methodology and is available on pandoragroup.com.
Adding a 5th C is a response to increasing consumer expectations to sustainability, and Pandora will share its methodology and findings with other jewellery makers to inspire greater transparency across the sector.
Pandora Lab-Grown Diamonds are currently available in the US, UK, Canada, Australia, New Zealand and Denmark with more countries to be added soon.
