Polished Diamond Prices Slip in SeptemberOctober 06, 15
The broad market IDEX Index for global polished diamond prices showed a modest decline in September, but this single index does not tell the whole story. Prices were mixed by size. Here’s the underlying detail:
· The IDEX Index of Global Polished Diamond Prices averaged 130.4 during September, down from 132.2, the average for both July and August. The good news: prices held steady during the final two weeks of September.
· On a daily basis, prices drifted slightly lower early in the month. Polished diamond prices reached a daily high of 132.9 on the IDEX Index on the fourth day of September, but drifted lower to the 128-129 range mid-month, and held steady in subsequent days.
· There was a wide variation in price trends by size of stone. Diamonds in the 0.5-carat range dropped significantly in price. Further, 4-carat stones also dropped in price. Stones ranging in size from 1carat to 3 carats posted varying gains on a month-to-month basis.
