The jadeite is natural Burmese jade. It is well known in the trade as 墨翠. It looks black, however, it is green when light shines through.Despite that, there is also a difference in quality. For a jadeite which is very translucent with even green seen under the light, it can be in thousands and above, depending on the size. Whereas for those that are less translucent, with mainly black or little green seen under the light (in photo above), they can be in hundreds and below for a big piece of pendant. These two pieces are of good quality. Totally black with good lustre, yet green throughout when light shines through. They can be set into ring and pendant.Dimensions of small clover: 6mm x 6mm x 2.4mmDimensions of big clover: 7mm x 7mm x 2.3mmFeel free to customise them and we will set them at cost for you! * The small clover is sold.
