The reality TV star was targeted by gunmen in Paris this week as they stormed her apartment, but she is said to be confident that they will be able to find the expensive rock if the criminals try to sell it.
According to TMZ, her police report 'includes the diamonds inscription number' and other marks to help it be identified.
The Gemological Institute of America adds that inscribed diamonds reported to the police as stolen are flagged in the system, which means authorities can be alerted if they are cleaned, graded or put up for sale.
However, the report adds that it's not foolproof, with bigger rocks able to be crushed to make them less traceable, and the thieves could avoid legit jewelers.
Meanwhile, according to TMZ, there was no surveillance video inside or outside the apartment complex where the reality star was bound and gagged.
The site claims police have canvassed areas nearby for CCTV footage, but have so far come up blank.
They also claim Kim only had one mobile phone stolen during the robbery - and that it did not contain "compromising information".
It was previously reported the 35-year-old's two smartphones were stolen in the raid. Kim's mobile is said to have been 'remotely wiped'.
