(IDEX Online) - Prices for March followed a similar pattern to recent months, with no movement at all in the majority of carat, color and clarity categories and a mix of fluctuations in those which did see change.
Smaller stones, (up to 0.39) both round and fancy, were at a virtual standstill.
The trend among changes that were seen in the 1.00-1.24ct rounds was generally up, by around three per cent, among better colors (D to H) and SI3+ clarities.
Below are some highlights from the April 1st Price Report. IDEX members can see the full IDEX Price Report and changes for all sizes by clicking here.
