The NFL star - who was famously acquitted of killing his former wife Nicole Brown Simpson and her friend Ron Goldman in the 1990s - died in April aged 76 following a battle with cancer.
His remains have been transformed into cremation jewellery, according his lawyer Malcolm LaVergne.

According to TMZ, LaVergne "didn't want to say exactly what kind of jewellery pieces the children got" but reported that the selection was mostly made up of necklaces or bracelets with miniature urns as pendants.
LaVergne was keen to stress that he did not get any of the jewellery himself, and that it has all been divided up between Arnelle and Jason - whom he has from his first marriage to Marguerite Whitley - as well as Sydney and Justin Simpson, who were the result of his marriage to Nicole.
The family were the first to announce news of OJ's passing earlier this year.
A post on OJ's account on X read: "On April 10th, our father, Orenthal James Simpson, succumbed to his battle with cancer.
"He was surrounded by his children and grandchildren. During this time of transition, his family asks that you please respect their wishes for privacy and grace."
In February, the former NFL star dismissed reports he had been placed in hospice care after battling prostate cancer.
He said in a video: "Hey X world, hospice? Hospice? You're talking about hospice? No, I'm not even in the hospital. I don't know who put that out there.
"In any event, I'm hosting a ton of friends for the Super Bowl here in Las Vegas, and all is well. So hey guys, take care, and have a good Super Bowl weekend."
