Diamonds are currently the most valuable 'white' gemstone and are valued based on their colour, clarity, size and brilliance.
Diamonds are shaped and cut in various ways which determine their brilliance. One of the most popular diamond cuts is the 'modern round brilliant-cut', introduced in the early 20th century. Modern round brilliant-cut diamonds are uniformly faceted as opposed to 'old brilliant-cut' diamonds, which are less uniform in proportion, have a polished culet point and are deeper.
Old brilliant-cut diamonds were most prevalent during the Georgian and Victorian eras. The illustrated late 19th century riviere necklace is a fine example comprising graduated, old brilliant-cut diamonds set within open backed, cut down collect settings that allows light into the stones, resulting in a magnificent piece of timeless jewellery.
