The price of a ring-size single-carat stone has fallen by 37 per cent. To survive, luxury jewellers will have to persuade their clientele that a natural diamond is still worth the outlay.

Chinese scientists have created a ‘super diamond’ 40% harder and far more durable than natural ones. Experts say the creation could lead to breakthroughs across several key industries that rely on diamonds,

Sonny Jogia, managing director of Sonny's Jewellers and JQ Diamonds in Birmingham, said there was a "big demand" for affordable lab-grown fashion jewellery. "There was massive reluctance from a lot of businesses around here initially," he said.

Chinese scientists make ‘super diamond’ 40% harder than real thing - Material may find applications in machining, drilling, or even in engagement rings, scientists say

Lab-grown diamonds offer the same brilliance, durability, and beauty as natural diamonds while being more affordable, ethical, and eco-friendly. As the demand for sustainable luxury grows, India’s lab-grown diamond market is projected to see significant growth,

A group of scientists from two universities in China have created an ultra-hard, high-quality ‘super diamond’ in the lab that is many times stronger than naturally occurring diamonds. The team responsible for the breakthrough believes their creation could have applications in key sectors,

Scientists have struggled to recreate lonsdaleite in the laboratory but now, a team of Chinese researchers have engineered a way to synthesise “well-crystallised, nearly pure” hexagonal diamonds from graphite.
