If you want the ring to be an investment, to grow in value, and to be later passed to the next generations, then your choice should be the engagement ring with a natural diamond or diamonds. For the last 100 years, the price of natural diamonds only grew. And in the future, their cost will continue growing because of the limited supply. The more diamonds are dug out, the fewer are left.
Natural diamonds can be easily re-sold, and the price is high enough. Often, you can even get a trade-in for 100% of the value, while lab grown diamonds usually aren’t eligible for trade-in at all or the price is very low.
