Halle Berry engagment ring is a 4-carat emerald that comes from "closed-down mines in Muzo, Colombia and the color is perfect," a source claimed.

Halle Berry's engagement ring has hidden code and symbols as well, a jeweler has revealed.

She was given the ring by fiancé Olivier Martinez and details about the ring he presented to his "Dark Tide" co-star were told to People Magazine.

According to an earlier report:

Jewelry house Mazlo told the US celebrity and entertainment magazine that the engagement bauble hides meaning in codes and symbols that only the twosome can decipher.

"The ring is textured and contains codes and symbols which you cannot see," spilled the jeweler, "only the person wearing it can." Further pointing the uniqueness of the ring designed by Robert Mazlo, the jeweler added, "It's very uncommon. The symbols and codes represent [the couple's] story and only they can interpret it."

The design house also noted that the ring is "a one-of-a-kind piece and cannot be replaced." Its 4-carat emerald comes from "closed-down mines in Muzo, Colombia and the color is perfect." The jeweler continued on gushing, "The balance between the blue and the yellow in the green in that stone is perfect."

More on Halle Berry, the ex wants more money before that wedding...

Gabriel Aubry wants to "substantially increase" the monthly payments he receives from Halle Berry.

In an earlier court case, he did not get the chance to have his case heard as the judge granted a continuance, but he will press for more money.

Halle wants to move to France with Nahla and her fiance Olivier Martinez because of concerns about the paparazzi and the child's safety, but her ex is trying to stop her from re-locating because he believes he won't get to see his daughter.

It was previously revealed Gabriel – who split from Halle in 2010 after five years together - was worried Oliver is planning to adopt Nahla.

A source said: “Gabriel fears that Halle's ultimate plan is to get him out of his daughter's life, permanently.

"He believes the plan is for Halle to move to France with Nahla and then have Olivier adopt her as his own. She wants a ‘fresh start’ apparently."

"Gabe will fight tooth and nail to retain custody of Nahla. He loves that little girl and is determined to always be a part of her life and always be her father.

"Just because Halle is through with him doesn't mean she can shut him out of her daughter's life too. Gabe may not have Halle's money or power but he will not just lie down and take it."
