Despite the modest gains last week according to polishedprices, IDEX research shows that polished diamond prices dropped again in October, continuing a trend seen since August. Overall, prices were down 3.4% compared to September and exhibited a steady slide from the beginning of the month. On a year-over-year basis, 0.5-carat diamonds declined by 15.3%, while on a month-over-month basis they declined by a more moderate 2.9%. "In fact," writes Danielle Max, "diamonds of all sizes – with the exception of 4-carat stones – saw declines, with 3-carat stones dropping by a noticeable 5.5% month-over-month. Four carat stones, on the other hand, increased 4.8% year-over-year and a modest 0.7 percent on a month-over-month basis."
