natural amertrine 9ct YG ring

this ring has a magnificent amertrine. the main feature of this stone is that it is a bi color of amethyst and citrine, depending on the angle of the stone & the light it will display different colors, weather it being purples for amethyst or yellows of citrine or it will show 2 distinct colors. the rough material was brought in a preform state which we then faceted ourselves. we brought the preform as natural untreated stones in good faith.
