Mother-of-pearl in new area of land (5)
I believe the answer is:
nacre
'mother-of-pearl' is the definition.
('nacre' can be a synonym of 'mother-of-pearl')
'new area of land' is the wordplay.
'new' becomes 'n'.
'area of land' becomes 'acre' (I've seen this before).
'n'+'acre'='NACRE'
'in' is the link.
(Other definitions for nacre that I've seen before include "valuable material" , "Mother-of-pearl - crane (anag)" , "Mother of pearl" , "inside of shell" , "Constituent of inlay furniture" .)
