T.K. Muhammed Haji was born on December 4th, 1966 in Aroor, Malappuram. He had 4 siblings. He has been ambitious from his childhood itself, and was encouraged by his parents, who had a very humble background. They motivated him to chase his dreams. He enrolled in Pocker Sahib Memorial Orphanage College in Tirurangadi but dropped out and joined with his uncles to study business from their small retail businesses & shops. Post that he opened a small grocery store in his hometown, but had to shut it and leave for the Gulf just like any middle class boy who had financial instabilities and lots of responsibilities on his shoulder, back then. Mr. Muhammed worked abroad for more than 20 years before coming back to his homeland to fulfil his dream of building a jewellery group.

In 2012, Muhammed Haji has came back and opened the first showroom of Landmark Gold and Diamonds in Malappuram district, partnering with one of his cousins. In the next 10 years, Landmark has grown into 3 succesful showrooms in Malappuram, Calicut and Kasaragod respectively. The group has also introduced their own Diamond brand, Sierra.
