Apparently Mahabharata mentions Lord Krishna giving importance of shaligram to yudhisthra in bhisma parva-

I chant this saligram strotra matra in front of Lord Narayan Hrishi
O Lord of lords Purushotama, I request you to tell me the saligram significance
Himalaya is situated on the bank of river Gandaki. To the south of this Himalaya a big and beautiful land is situated where you can find saligrams sila. This is the place where Devi Dwarabati begins. This place is called Mukti Kshetra.
Saligram Silas found here are very precious and significant. These silas represent Lord Vishnu and the person who worship or keeps them in house or washes them and drinks the water or sprinkles it on his head becaomes free from all sins and is protected from untimely death. That person becomes free from all sains and diseases. The most feared sin Bramahatya ( Killing a Brahmin) is also washed away by worshiping Saligram.
The person who washes saligram with chakra everyday get rid of sins like Bramahatya and if he drinks the water daily, gets the boon equal to a thousand yagyas of Lord Vishnu.
The person, who worships saligram with Tulsi leaves daily, gets the boon of million Yagya.
Except damaged and broken Sila all silas are good to worship
Without worship, without offering any sweets or without any pilgrimages only chanting this saligram mantra is enough to wash away the sins and for the fulfillment of all desires.
There are various sizes and shapes of saligrams in which Lord Vishnu is situated in different incarnations.
Good Luck increases and gets satisfaction from children in every aspect by worshipping saligram black in color with little chakras
Person who gets the chance to look at the Vahudev sila becomes free from sins. Shreedhar, Sukar,Vam, Harivarna, Varaha, Kurma and lots of other type of saligram are available. some Saligramas have the marks of cow feet and Narshimha Avtar.
Yellowish Saligram is very auspicious as Lord himself but reddish saligram is consider fearful and dangerous. Sankha, Cakra, Gada, Kurma are printed on saligram. Saligram with Sankha (conch) sign is considering Vamrup of lord Vishnu, where chakra in the middle is consider as Damodar saligram. Saligrams of different shapes – round, umbrella shape which has white lines are available; worshiping this kind of saligrams gives wealth and reputation in society. Flat shape saligrams create sorrow in family and saligram with sharp front side create war and tension in family
Saligram which have chakra around the head or on forehead and rest parts and clean and smooth are very auspicious and considered as Vamdeva sila. Yellowish or black in left side with chakra is consider as Laxmi Narshimha sila.
Worshipping long shape sila create poverty, and saligram having lagna chakra creat measures diseases even death.
Person who offers Tulsi leaves while worshipping saligram gets salvation and can stay at Vaikuntha (Place where Vishnu live) for a million years.
Therefore always worship saligram, chant saligram stotra which is very beneficial for mankind. We can get higher post on Vishnu Lok for doing so. All sins will be destroyed and one gets Vishnulok from worshiping the saligram.
There are various types of description available for Lord Vishnu’s ten incarnation therefore Lord’s incarnation Shree Saligram’s worship, Prayer and drinking the water washes away sins of a million lives and gives prosperity, wealth and reputation so Saligram should be worshiped.
Garuda purana too mentions about shaligram, but the story of vrinda-tulsi is not found in itihasas and vaishnava puranas.
The story of vrinda and tulsi is only found in shaiva puranas, which well most vaishnavas would reject, also the story is clearly shruti virodhi as Vishnu is described as fully celibate in Vedas and satwik puranas, so this story doesn't gel out with the character.
