Holiday forecasts from Bain, Mastercard and others predicted holiday sales would grow this year but didn\u2019t include jewelry in that assessment. However, a survey<\/a> of independent jewelers showed festive sales, and especially those of natural diamonds, were going well.<\/p>\n\n\n\n There was a lot of talk surrounding De Beers, as the company extended its sightholder contracts by six months and both Botswana and Angola announced<\/a> they were seeking a stake in the mining giant. Meanwhile, lab-grown was a popular subject. The World Jewellery Confederation (CIBJO) said it wanted to remove the term lab-grown from its Blue Book, and Signet Jewelers raised its full-year forecast following strong sales, in large part thanks to lab-grown fashion jewelry.<\/p>\n\n\n\n In September, the price for the 1-carat RAPI softened to $4,437 by month’s end, down 0.9% from the previous month, when the index had fallen 1.1%. Better clarity diamonds in the D-H IF-VVS category led the decline in the index, falling an average of 1.1%, while the mid-tier VS quality diamonds fell only an average of 0.5%.<\/p>\n\n\n\n D-F and G-J SI categories saw a decline of an average of 2%, while in August they fell an average of 3%. Low-quality diamonds in the K-M VS-SI category saw an average decline of 1.8%, compared to August when they fell an average of 0.9%.
