Diamonds in the Rough launched in 2003 to create jewellery set with rough, unpolished diamonds. They offer a spectacular array of pieces sold through high end retailers (see the list of stockists on their site.)

These are from their Orielle collection and feature 23.37 carats of rough stones, accented with .85 carats of micro pave cut diamonds set in yellow gold. There are no prices on the web site.
