Laboratory-grown diamonds are booming in popularity as newlyweds opt for a more sustainable alternative to mined gems.
Some jewellers say interest has grown by more than 2,000% in five years, as people look for more affordable options.
They are physically and chemically identical to their natural counterparts but cost up to 85% less.
Lab-grown diamonds are increasingly being seen as the better-value alternative.
And a study of 1,500 would-be husbands and wives in the UK found 70% would be willing to opt for them.
Value for money (55%) and sustainability (43%) are the main reasons they’d make the switch to lab diamonds.
While 69% admitted they wouldn’t be able to tell the difference between the two types of gems.
Following the findings, passers-by were challenged in a video test to tell the diamonds apart.
It comes as diamond retailer Queensmith revealed the market for lab-grown diamonds has increased by 2,860 % in five years.
In 2019 its lab-grown sales were 1% of overall sales but this year they account for 81% of overall sales.
A spokesperson for the brand said: “It’s no surprise to see people willing to move away from mined diamonds.
“Lab-grown diamonds provide a great alternative.
Over half of engaged people would choose cheaper rings if it meant they could spend more on their nuptials.
The venue (53%) and the wedding outfit (34%) are the main priorities – with wedding rings (31%) in third place.
The changing attitude towards gems is highlighted by 71% feeling lab-grown diamonds will be the new normal in the future.
For some, that future is already here, as 27% already owned jewellery with a lab-grown diamond in it.
While 32% knew of others who had bought lab diamond jewellery.
Away from weddings, the top containing non-mined diamond gifts people would buy include necklaces (52%), earrings (50%) and bracelets (44%).
When it comes to knowledge of lab alternatives, 26% felt they had a good grasp of what they were.
During HPHT, pure carbon is pressed within a metal cube and exposed to immense heat and pressure through electric pulses.
The carbon breaks down and crystallizes into a diamond.
Any metal traces within an HPHT diamond will be minuscule and usually not visible to the naked eye.
Most experts consider HPHT diamonds to be better quality than CVD diamonds.
