Hello Dear Steemian,
If you remember Kim Kadarshiyan the Famous actress and model who had lost her precious ornament in theft in Paris in 2016.
At that time she had given an interview and suggested that if my Diamond might have kept in block chain based ledger then I would have tracked it easily.
Lot of people have taken this very seriously and noticed the importance of Block chain.
Now one Hong Kong Based Diamond Jewelry shoo has started to maintain the ledger of Diamond holder through the Block chain based ledger and it has got great response during 24 hour of his announcement.
