What type of diamond is good for investment value?
Diamond prices are based on demand and supply and that varies with many factors. In the past, 1+ carat high quality diamonds were sold sooner than bigger stones, today any diamond that is 4 carat upwards with high quality is sold within a day…. so, the bigger the better. In general, I would recommend buying DEF/VVS in 2ct + for the longer term, and the same quality in 1.10+ for the 3-5 year term. All this is based on buying from us at direct from Antwerp prices rather than from designer shops were no matter what diamond you buy you will lose ca. 50-70% as soon as you walk out of the door due to the retail margins.
