Rio Tinto plans to hold a 'Specials and Colored Rough Tender' in Israel at the Israel Diamond Exchange next month, reports say. The tender, slated between October 11-15, would offer large and fancy colored rough stones varying in size from 10.8 carats and larger.

The company noted that its clients who would be invited to participate would be offered high-value large single stones, parcels and natural colored rough diamonds of varying sizes, shapes, qualities and colors, including pinks and fancy yellows, reports add.
