It’s the most unique of the entertainer’s engagement rings yet.
Jennifer Lopez has debuted her rarest diamond engagement ring yet.
News broke over the weekend of the actress-singer-entrepreneur’s engagement to rekindled flame Ben Affleck, with Lopez sharing a video engagement announcement via her newsletter.
In the video, she sported a large green diamond, estimated to weigh 8.5 carats, on a platinum or white gold band, flanked by two white diamond side stones.
A clip from the video shared by a J. Lo fan account can be seen below.
According to the Gemological Institute of America, green diamonds are extremely rare. They are found in South America and Africa.
From 2008 to 2018, diamonds with a “pure” green, blue, or red color comprised less than 0.07 percent of all diamonds the GIA received for grading worldwide.
In an article published in “Gems & Gemology” in 2018, Christopher M. Breeding, Sally Eaton-Magaña, and James E. Shigley wrote that green diamonds are the result of structural defects from radiation exposure, or nitrogen, hydrogen, or nickel impurities.
Since the 1940s, people have used laboratory irradiation treatments to achieve a green color in diamonds, mimicking the process that happens as a result of radiation exposure.
Therefore, the authors wrote, it can be difficult to ascertain if a diamond’s green color is naturally occurring or man-made.
There is record of large, naturally occurring green diamonds, however. The largest is the 41-carat “Dresden Green” recovered in India from the famed Golconda mines sometime prior to 1722.
In the modern era, natural green diamonds have fetched millions per carat at auction.
The 5.03-carat “Aurora Green” sold for $16.8 million, or more than $3 million per carat, at auction in 2016, while the 5.5-carat “Ocean Dream” blue-green diamond earned $7.8 million, or $1.4 million per carat, in 2014.
Experts underscore how rare and unexpected Lopez’s green diamond is.
“A green diamond is a bold and unique choice, appropriate for J. Lo,” said Ben Bridge Jeweler President and CEO Lisa Bridge. “A ring like this may cost upwards of a few million dollars.”
Colored diamond expert Brian Denney of Gems of Note said from the photos he’s seen, he would guess Lopez’s rock is a fancy intense green-yellow diamond.
“I think it’s one of those unique stones that has almost a neon appearance due to strong green fluorescence,” Denney told National Jeweler.
Fluorescence can create a glowing effect. Certain colored fluorescent diamonds “almost look like a highlighter,” Denney explained. “It’s a really unique characteristic and one of my favorite color features in diamonds. They just glow.”
Denney estimated Lopez’s rare green-yellow diamond to cost $1 million per carat, for a total price tag of $8.5 million.
Brittany Wyeno, Shane Co.’s director of stone inventory, has a more conservative price in mind.
“In comparing it to similar natural fancy diamonds currently on the market, our guess is that the retail price of this 8.5-carat ring falls anywhere from $1 million to upwards of $5 million,” she said, noting the stone is “incredibly rare.”
Lopez’s newest ring continues the colored diamond trend for the celeb. Of Lopez’s six known engagements, three have featured colored diamond center stones.
