If you are talking from a diamond mining perspective, that statement is 100% correct. From jewelry shopping perspective, not so much. As they continue to increase in popularity fancy colored diamonds. All green precious stones are emeralds, right? At least that’s what many people think. In fact, however, they are quite wrong if they do. Many pink diamond engagement rings are crafted using diamonds that vary in both color intensity and in secondary hue. Many pink diamond engagement rings that boast a secondary hue are still extremely beautiful and valuable and have a unique appeal all of their own. Colored diamonds have, in terms of fashion at least, started making a comeback in a big way. Whether they are influenced by celebrity trends or are simply looking for something a little bit different an increasing number of women are adding blue diamond engagement rings to those Pinterest inspiration boards (which should serve as hints rather than simple inspiration for their other halves) in increasing numbers.
