MOROCCO

During the year 2020, images, videos and many rumors began to circulate about the discovery of high-quality Golds in the Southwest of Morocco. With the Covid situation it was difficult to go to or to leave Morocco, so it was quite a long time until the first pieces arrived in Europe. Once here, very reliable analyses had to be done to ensure that these new Golds were natural. They were so perfect and, some of them so different from the Golds that had been known before from Southwestern Morocco that to avoid suspicions it was best to have the analytical data prior to putting them on sale. Between one thing and another we have had to wait a bit but at the end of 2020 we can finally offer these specimens of great beauty and very different from what has been known so far.
We attach here the analysis, which as you can see is very complete, to avoid doubts about it.

ML16AM4: From a very recent find in the area of Western Sahara in Morocco, with the specific location yet to be determined, this specimen of Gold, very well crystallized and with brilliant luster, displays a sharply defined morphology, with the dominant forms of the octahedron, twinned according to the spinel law, with curious hooked ends and with minor Quartz.
We will see what the future of the locality holds for these high quality absolute novelties.
This material has been carefully analyzed, and we will send a copy of the analysis to the buyer.
