This amazingly vibrant Ingido Blue Victoria Stone cabochon. It has a brilliant polish on the top, and is backed with basinite to add height proportionate to its generous size. This stone is phenomenal and absolutely gorgeous. It has large, wonderfully chatoyant formations that shimmer with any movement; the largest formation is shaped similar to a ginko leaf. The cab is a slender triangle with gently rounded sides and corners, tapering to a point at one end. It would make a stunning focal stone for a necklace, or enhance a gem collection.
Victoria Stone Factoids:
Victoria Stone is also known as “Imori Stone”, named after it’s Japanese creator, Dr. Imori. It is not an artificial or fake stone. What Dr. Imori was able to accomplish was to actually blend several different minerals using a special process known only to him to come up with an Imori Stone,commonly called Victoria Stone. This beautiful reconstructed gem is mineralogically similar to Nephrite Jade. It has a harness of 6.
It was laboratory produced from natural raw materials such as quartz, feldspar, magnesite, calcite, fluorspar, etc. for a total of seven different minerals-fused together under high pressure and a high temperature and again mineralized to make this gem by adding special crystallizers and habit regulators.
This is not an imitation or synthetic but is a reconstructed natural stone. The boule of Victoria stone was slowly cooled down for 35 to 40 days to make it crystallize into the pretty fan shapes.
Victoria Stone is minerlogically similar to nephrite jade, but the arrangement of the actinolite crystals is different. Instead of the crystals interlocking and
tying together as they do with jade, they have crystallized in fan shapes to provide the beauty of the stone.
Victoria Stone could be bought by the boule or in slices when it was produced in 15 different colors from 1960 to the 1980’s –green, sky blue, reddish purple, yellow green, blue green, sky indigo, chocolate, yellow, deep indigo, white, quiet green,quiet yellow, quiet blue, grey and black.
The hardness is 5.5 to 6, specific gravity of 3.02 and a refractive index of 1.12.
Dr. Imori died without confiding in anyone how the process worked and no one has been able to duplicate it. There is only a limited and nonreplenishable supply of Victoria Stone in existence, when this material is used up to make jewelry and cabochons, it will become scarcer and about
impossible to find.
Since there is only a limited and non-replenishable supply of Victoria Stone in existence as this material is used up making jewelry and cabochons, it is steadily decreasing in availability, with a corresponding increase in price and value.
