Gemologists have long used machines in diamond grading but technology has made it possible for them to “learn” how to do it on their own.
September Birthstone Baubles
Senior Editor Brecken Branstrator rounds up 10 pieces of jewelry set with sapphires, a gemstone that’s been selling very well lately.

I know that sapphires are hardly an obscure, up-and-coming gemstone but even so, I feel like I’ve been hearing a lot about the gem for a while now.
Every time within the past year that I’ve been at a show or working on a story that involves talking to dealers and suppliers about which gemstones have been selling well, sapphire was sure to get a mention.
And not just the classic blues, which of course continue to top many best-seller lists, but also the fancy-colored sapphires--the pinks, lavenders and peaches especially that offer great colors and appeal to the Rose Quartz/pastel gem trend.
It’s amazing to see a stone that’s been worn for thousands of years to have something of a resurgence.
Sapphires always have had a prominent place in history. Medieval clergy wore the gems to symbolize heaven, while commoners thought that they might attract “heavenly blessings,” according to the American Gem Society.
The lore swirling around the stones today says that they can be used to protect loved ones from envy and harm, or even to encourage loyalty.
Here are 10 pieces of jewelry to showcase the month’s birthstone.
