Over the past 10 years, there has been an explosion in cheap lab diamond and moissanite producers in China and India. 10 years ago, it was hard to find quality lab diamonds at a reasonable price, and moissanite was still reasonably expensive at $400-600/ct.
Today, given cutthroat competition and "race to the bottom" pricing strategies, lab diamonds are ubiquitous, extremely high quality, and cheap. Less than $200/ct and sometimes much less: https://detail.1688.com/offer/751071300271.html
Within 10 years of today, I expect diamonds to lose almost all of their value. Moissanites have already become as near-worthless as synthetic rubies. This is going to open up new industrial uses for those gemstones.

Moissanites are now less than $5/carat at retail: https://detail.1688.com/offer/586468555080.html
These are legit. I've bought some.
