Godsend, having flashy jewellery round eastern ship (8)
I believe the answer is:
blessing
'godsend' is the definition.
(I've seen this before)
'flashy jewellery round eastern ship' is the wordplay.
'flashy jewellery' becomes 'bling' (I've seen this before).
'round' is an insertion indicator.
'eastern' becomes 'e'.
'ship' becomes 'ss'.
'e'+'ss'='ess'
'bling' going around 'ess' is 'BLESSING'.
'having' is the link.
(Other definitions for blessing that I've seen before include "Grace said before a meal" , "Protecting prayer" , "Approval" , "Godsend" , "Asking God to look favourably on" .)
