Greetings. What you have is something called melanonychia.. This is common in people of Indian or African origin / or in brown and darker skin types. However if it's very dark and only in a single nail, just see a qualified dermatologist for reassurance or you could alternatively send pics on follow up messaging. Hope this helps. Warm regards.
