Sapphire - Madagascar/ Tanzania. Total weight 79.42 cts. Ref. UM/7
A mixed parcel of heat treated and glass filled 'pink' Sapphires from Madagascar and Umba Sapphires from Tanzania. The Umba stones are unique in the range of colours shown, usually in the blue to purple range sometimes pink and green. They not only show a strong dichroism - that is, they show two distinct colours - many, but not all, of the Umba Sapphires also show a strong to medium 'colour-change' depending whether they are observed in daylight or incandescent light. It is this phenomena which makes they extremely difficult to photograph as usually the camera picks up the color-change shown in incandescent light.
The Umba stones are all graded AA+ in clarity, the Madagascar stones are closer to AA grade.
Photographs show the parcel in strong daylight, in shade, and under LED light.
The parcel consists of 20 stones, with a combined weight of 79.42 80 cts and is priced at $1760.00 for the parcel.
That is a cost of just $22.00 per ct!
Now beat that for value!!
