The 18 Most Popular Stories of 2018
Lab-grown diamonds, engagement ring trends and a financial scandal that rocked the industry were among the most-clicked-upon by our readers.

Lab-grown diamonds, engagement ring trends and a $1.8 billion bank scandal in India that rocked the diamond industry nationwide were among the most popular stories published on NationalJeweler.com this year.
While there are a few important stories that did not make the cut—I was surprised, for example, that the article announcing De Beers would begin selling gem-quality lab-grown diamonds did not land in the top 18—I would say this year’s list is a fair representation of what’s important to the industry right now.
The increasing prevalence of man-made diamonds. The decreasing availability of financing. What kind of engagement rings consumers want. Beautiful and unusual gemstones.
I am currently on vacation, visiting my parents in the land of alligators and golf over the Christmas holiday, returning Dec. 27 to finish out the last few days of the year.
In the meantime, enjoy this blog post as well as Senior Editor Brecken Branstrator’s annual tribute to those to whom we’ve said goodbye over the past year.
Happy holidays to all.
