Ametrine is the trade name given to an unusual variety of quartz that exhibits the colors of amethyst and citrine side by side. However, here the flashes of purple, yellow, and pink, although not side by side are still probably enough to assume the appellation.
The Mouawad Pink diamond is weighing 21.06. having a radiant-cut, fancy pink colour, and a VS-1 clarity. Its cut is a combination of the emerald-cut (on the top) and the brilliant-cut (on the bottom). Although this Mouawad Pink is the smallest Mouawad's collection of diamonds in size, still, its estimate value is over 12 million US dollars.
Rhodochrosite gets its name from the Greek term meaning "rose coloured". The gem is soft and has a grainy structure with a white lace-like banding that it's difficult to cut around. The colour is very desirable, since translucent pink is otherwise uncommon among affordable gemstones.
