The theft targeting the TV personality, socialite and businesswoman in 2016 was carried out by a group dubbed the “grandpa robbers”.
A six-member jury, led by three judges, reached a verdict on Friday following a four-week trial at Paris’s Palais de Justice.
The court found the ringleader and seven others guilty over the raid.
After the ruling, 44-year-old Kardashian, who was not present for the verdict, issued a statement, saying: “I am deeply grateful to the French authorities for pursuing justice in this case.
“The crime was the most terrifying experience of my life, leaving a lasting impact on me and my family.
“While I’ll never forget what happened, I believe in the power of growth and accountability and pray for healing for all. I remain committed to advocating for justice, and promoting a fair legal system.”
The court in the French capital acquitted two of the 10 suspects.
Five of the defendants, who were all aged between 60 and 72 at the time of the incident, faced armed robbery and kidnapping charges.
The remaining five defendants were charged with complicity in the heist or the unauthorised possession of a weapon.

The group were accused of pulling off one of the most audacious heists against a celebrity in modern French history in the early hours of 3 October 2016, storming Kardashian‘s luxury hotel apartment and stealing jewellery worth an estimated $6m (£4.4m) at gunpoint.
The ringleader Aomar Ait Khedache, 69, was sentenced to eight years in prison, with five of those suspended. Three others who were accused of the most serious charges got seven years in jail, five of them suspended.
During the robbery, Kardashian, who previously told the court she thought she would be raped and killed, was bound with zip-ties and left in the bathtub.
She described the robbery as “terrifying” and said while she felt forgiveness, that in no way altered “the emotion and the feelings and the trauma,” adding “my life is forever changed”.
Two members of the group – Khedache, known as “Old Omar”, and Yunice Abbas – who wrote a book called I Kidnapped Kim Kardashian, admitted some part in the robbery, while the remaining eight denied the charges.
Prosecutors had requested sentences of up to 10 years.
Kardashian, who earlier this week completed her six-year legal apprenticeship in California, was not present to hear the verdict.
The jewellery, which is understood to have been sold in Belgium, was never found.
