Bobbi Kristina’s is just a teeny bit smaller. Kate’s sapphire, which once belonged to Princess Diana, is 18 carats. The teen’s version could be worth anywhere from $50,000 to $100,000, depending on its oval-cut center stone. Sarkissian explains that some sapphires are heated in order to give them a more brilliant blue color, yet it’s impossible to judge Bobbi Kristina’s based solely on a photo of the gem. He adds that the round-cut diamonds surrounding the sapphire add approximately another $10,000 to the ring’s worth. It’s unclear how Gordon, who ostensibly does not work, could afford such a pricey rock.
Colored stones like sapphires, emeralds, and rubies have become very popular in recent years, thanks to Middleton, Jessica Simpson, and Halle Berry – although “generally it’s done on a smaller scale, like a 3-5 carat sapphire and a half a carat of diamonds around it,” says Sarkissian. Still, given Bobbi Kristina’s age, “to have one of this size is a bit ridiculous, but I guess in today’s era anything is possible.”
Bobbi Kristina and Gordon, who began dating immediately after Houston’s February death, announced their engagement to her family in a new clip to promote their E! reality show, “The Houston’s On Our Own,” which premieres on October 24. In the preview, Houston’s brother Gary confronts Gordon, saying, “No one knew that from a godson you would turn into a boyfriend,” to which Gordon retorts, "Nobody has to be in my business."After Houston’s death, Bobbi Kristina was spotted wearing her mother’s diamond ring, which initially sparked rumors that she and Gordon were engaged. In recent photos posted on Bobbi Kristina’s Twitter page, she wears the sapphire on her left hand and her late mother’s diamond on her right.
