![]() ![]() Its possible that they radiate around an accumulation of volatiles. The exact reason for the formation is hypothesized to be the consequence of rapid mineral growth after nucleation. They are especially common in Silica-rich Rhyolites (think rainforest jasper). Spherulite is a term for the radiating structures we call orbs. ![]() This stone is in fact a spherulitic variety of chalcedony. Ocean Jasper is not unlike most of the other gems in the mainstream market in that it has been given a simple trade name. The location found by Paul Obenich has been “Mined Out" since 2006, which means miners have exhausted its supply and what is on the market currently for the location Maravato, Madagascar, is all there will ever be. The location is only visible during low tide, which made efforts to search quite challenging! Ocean Jasper was then brought to the Tucson Gem Show in 2000 and was an instant sensation. Again, this was followed with the disappointment of not knowing where exactly it had been found.įast forward to 1997 when an ambitious Paul Obenich of Madagascar Minerals spent 45 days searching the coast of Madagascar and finally found the location of the mysterious stone. In 1950 a piece of Ocean Jasper was brought to the Museum of Sciences in Paris, France. Ocean Jasper was first discovered in 1922, but there was no information as to the locality (other than somewhere in Madagascar). The reason for this is that new veins within existing mines have been exposed periodically causing waves of new ocean jasper to hit the gem market. ![]() My friends out there who have collected for more than a few years will notice that it has changed in looks over time. Ocean Jasper, or Orbicular Jasper, comes (almost) exclusively from Madagascar. Today we are going to talk about a common stone that has changed in looks over time. I have enjoyed making you youtube videos, but I have no intention of abandoning this format anytime soon. It feels like too long since I've delivered some scientific factoids in literary form. ![]()
