Because the bi-coloured ametrine comes from only one mine in the world, it is sometimes collected if the depth of colour and the division of colour is strong, or if it has been skillfully or cleverly carved.
Ametrine, just like most crystalline quartzes is often eye-clean
In ametrine, a unique form of quartz mined from a single locality in Bolivia, the colours are both yellow and purple in areas of zoning
Ametrine can also be cut to blend the two colors so that the resulting stone is a mix of yellow, purple, and peach tones throughout the stone
Ametrine is most typically faceted in a rectangular shape with a 50/50 pairing of the two colors
Sometimes a checkerboard pattern of facets is added to the top to increase light reflection
Ametrine is also popular among artistic cutters and carvers
