The spectacular 'aurora' red-orange stones from Vietnam and Madagascar, even though there are no brown components in those stones, are also excluded by the AGTA definition because of their oranges of high saturation and/or dark tones, this is mainly because Sri Lanka has traditionally never produced such colors. Most dealers and gemologists feel that the Umba stones do not qualify because of their overly dark tones and strong brown (garnet like) component. Unfortunately, the results of that attempt almost entirely excluded the stones produced from the Umba Valley in Tanzania.
One color can be more predominant than the others,īut never without the others. The AGTA Lab recently took a variety of stones that dealers suggested met the criteria of Padparadscha and scientifically defined the color range using an imaging spectrophotometer. Orange with nice Pink-Yellow mixed in, to the darker tones of Orange with Pink-Yellow mixed in. At the other end of the color spectrum Padparadscha can run from a more predominant pastel Padparadscha can run from a more predominant Pink with nice Yellow-Orange mixed in, to the intense pastel tones of predominantly Hot Pink with Yellow-Orange mixed in, this means the Pink would be the more predominant color in the stone but the others are present and visible. Padparadscha is Corundum in the pastel shades of delicate Orange-Yellow-Pink. Padparadscha is the Sinhalese word meaning "lotus blossom". Padparadscha Facts February Birthstone Info
