Lazy lazy lazy TJC - there's just no reason to have accent diamonds with natts. That's cheap and unnecessary costcutting.
I've seen a stonking large diamond ring with natts (although when I used that word in the shop the assistant thought I was mad!), lovely diamond until you looked at it through a glass, and priced accordingly so quite a bargain.
I think 'natts' is short for 'naturals'
