Lab-Grown Diamonds and Price Comparison

Retail markups at purchase can exceed 100 percent, meaning immediate resale typically results in a significant loss unless the stone is exceptional or rare. Millennials interested in diamonds as an alternative asset often focus on liquidity, certification from labs such as GIA or IGI, and the reputation of the seller
