Jennifer Lopez and Ben Affleck marked their engagement with a gorgeous token — a green diamond ring. The music icon once wrote in her On the JLo newsletter that the color is particularly symbolic.

“I always say the color green is my lucky color,” Lopez, 52, previously wrote. “I’ve realized there are many moments in my life where amazing things happened when I was wearing green.”

Two diamond experts talked to PEOPLE about the unique piece of jewelry’s green diamond stone.

“The rarity of a natural green diamond cannot be overstated,” explains Grant Mobley, Diamond Expert at Natural Diamond Council. “Generally speaking, green is the second rarest natural color of a diamond with fancy red being the rarest. Only a small handful of green diamonds come to the market every year and almost never are they in the vivid color and size of this diamond.”

According to Andrew Brown, CEO of New York City-based luxury buying company WP Diamonds: “Green diamonds are indeed extremely rare. Not quite as rare as pink diamonds, but, the intense and vivid greens found to date have been smaller than pinks we have seen.”

While the exact shade of the sparkler isn’t easy to see, Mobley guesses it’s a fancy vivid green. “The exact color grading of the diamond has not been disclosed, but it is clear in the photos that it is exceptional and among the most rare.”

Where would such a unique color diamond come from?

Explains Mobley, “Green diamonds get their unique color from the exposure to natural radiation deep within the Earth after they have formed and this causes them to reflect green light. It is very rare for this to penetrate through the entire rough diamond and therefore is usually just a thin layer on the surface of the rough diamond. This fact makes green diamonds among the most difficult to cut and a diamond like this could have taken a year or more to plan and cut to ensure that it reflects the best cut and color possible.

If pure, Mobley says, “you can expect the value of this green diamond to significantly increase over time. Decades of price data show that all natural diamonds gradually increase in value over time and natural fancy color diamonds increase significantly faster and are therefore a very solid investment.

And both pros agree, this rare gemstone is an “incredible” sight in real life.
