Where Does Ametrine Come From ?
It will come as a surprise to many , but the Anahi Mine in Southeastern Bolivia is the single source of commercial ametrine production . Also found here are amethyst , citrine , and other bicolor stones . These are a combination of citrine and clear quartz ( bicolor citrine ) or amethyst and clear quartz ( bicolor amethyst ).
The Fascinating Color of Ametrine
Ametrine occurs in a band of yellow and purple . However , neither of these colors are intense and attain only medium luster . It is for this very reason that ametrine does not exhibit intense shimmer . Synthetic ametrine , however , is known to appear intense and vivid . Natural ametrine is renowned for showing the color transition from yellow to purple . Ametrine with 50 / 50 color splits enjoys maximum popularity , and is often the most preferred .
Why is the Cut and Shape of Ametrine Important ?
As there is not much choice for ametrine colors , the cutting and shaping of this gemstone become very important . Ametrine , in most cases , appears faceted . There are not many instances when the gemstone is found to be as a cabochon . Mostly , it is octagonal or rectangular cut with the stone reflecting both amethyst and citrine colors on an equal basis .
Step-style cuts are common in ametrine . Following are traditional oval and round faceted stones . Checkerboard facets are also not uncommon in the case of ametrine . However , it will be worth recounting here that Portuguese , as well as the scissor cut , have become very popular among jewelry lovers as they increase brilliance and light reflection of the stone .
