Expert notes:
In every auction, there is a remarkable stone. If there only had to be one, it would be this stone! A padparadscha of a color so vivid, so intense, so saturated; it is rare. In a gemologist’s lifetime, sapphires of this quality are less than the number of fingers on one hand. This padparadscha appears red, then a tender pink color adds itself to this primary red, to finally unveil an expression of bloody orange. Nature has decided. This color will be unique and well above all others. What a pleasure to be able to share this beautiful stone with Millon Belgique’s clients. It is very rare and it is really beautiful.

Expert notes :
From D to Z, no less than 23 colors define diamonds known as colorless. From very white to yellow, going from grey to pinkish, diamonds are actually rarely colorless. And yet, when they are D colored, we consider them colorless. A lower color, E, and we would write ‘nearly white’ on the certificates. Here, a round cut diamond of impressionable size and ideal color. No need for more to be a part of this 50 precious stones’ collection!

GRS Report nr. GRS2014-0412313 of 29 May 2014. This stone is so exceptional that the GRS Laboratory added an appendix to the orignal report and to mention that it is a GRS-type pigeon blood ruby (without strong fluorescence). No indication of thermal treatment.

Expert notes :
The very thin needles of rutiles are in 3D. They occupy the stone throughout its depth and cover the space alongside the suspended tiny crystals. There is no need to look through the microscope, the magnifying glass x10 will place you at the forefront of the stone’s performance.

ALGT Report nr. 61201533 of 28 April 2021.
Lees verder helvetica="" style="font-family: Roboto, " /> Dimensions : 10.14 x 7.46 x 4.74 mm.
Expert notes:
Close to the table, we can identify small inclusions conveying a black color on an inclined surface. It may probably be small (non-tested) protogenetic zircons surrounded by halos. The gemologic vocabulary seems hermetic, yet the explanation is simple. A spinel has formed itself in a conducive environment while small zircons were already present for several hundreds of millions of years. Two very distant geological eras are reunited in this stone, offering the result of an atypical and sought-after spinel.

Fancy vivid yellow natural diamond of 1,63 ct., clarity VVS1, round modified brilliant cut. Even distribution of the color. Very good proportions. Fluorescence : medium blue.
GIA colored diamond report nr. 2165637874, 27 October 2014.
Lees verder Roboto, " /> Dimensions : 6,89 - 6,91 x 4,53 mm.
Expert notes:
The cut, quite flat, is entirely astonishing because when we face the stone, we find ourselves confronted to a central pattern similar to a tunnel. We dive into the stone that is, in fact, not so deep. It is the paradox of this mysterious stone. The spring-like color gives the stone a great deal of light.
