Tina Knowles is calling out critics who bashed her daughter, Beyoncé, for recently wearing an extravagant Tiffany Diamond necklace for the jewelry company's new campaign, according to Page Six. The diamond is believed to have come from the colonial Kimberley Mines of South Africa in 1877 and has been nicknamed a "blood diamond."

"When you guys get engaged you won’t have a diamond you gonna put on a sterling silver band And you better check out where it came from and the origin of where came from and why you add it check out the calls for the Leather that you weird because they made it came from another country to to ban and not buy diamonds right because your righteous [sic]!!” Knowles wrote in response to a post from theGrio which highlighted one of the critics.

Beyoncé, who was featured for Tiffany & Co.'s new "About Love" campaign with JAY-Z, became the first Black woman to wear the 128.54-carat gem. She is also the fourth woman in history to wear the precious stone. But many social media users were apparently more concerned about the controversial history of the jewelry.

"This is not just 'a necklace.' It’s a blood diamond that was mined off the blood of South Africans. If they didn’t meet their quota, their hands and feet were mutilated or were just killed," a Twitter user wrote. "Nobody should wear the diamond."

this is not just “a necklace” it’s a blood diamond that was mined off the blood of south africans, if they didn’t meet their quota their hands and feet were mutilated or were just killed. beyoncé doesn’t have the timeline “up in arms”, nobody should wear the diamond https://t.co/YgsxDtvnTv

There were many more with similar sentiments.

“Beyoncé doing a Tiffany’s campaign wearing a blood diamond doesn’t sit well for her brand ESPECIALLY given her African influenced work in the past few years,” another person said.

Some social media users came to defend Beyoncé. The singer's supporters said Lady Gaga and Audrey Hepburn, who also wore the necklace, never faced backlash.

Knowles proudly highlighted her daughter's historic ad campaign in an Instagram post on Wednesday.

As Blavity previously reported, JAY-Z and Beyoncé also faced backlash for shooting the Tiffany ad in front of a painting by Jean-Michel Basquiat, a Black artist from Brooklyn who rose to fame in the 1980s. The critics said the late artist was an anti-capitalist who would have hated to see two billionaires posing in front of his art to sell diamonds.
