Diamonds are the girls best friend. There has to be at least one in an engagement ring. It’s up to the future groom to impress the woman he plans to propose with the shape and the size of the stone identified as a diamond in 1967. We can’t count how many engagement rings were produced. But we know that we can show how these rings were changing over the last 100 years. You will see in the video how different cuts like emerald, art deco, solitaire, princess cuts and round cuts were combined with white and yellow gold and platinum or more simple metals during the WWII. If you are trying to get inspiration for a perfect diamond ring, just to remind you that Lady Gaga has heart shaped diamond in the center of her engagement ring and the setting is a simple solitaire with pavé diamonds down the side.
