The primary coloring agent in most blue Spinels is iron (ferrous iron, Fe2+), as it is in Aquamarine Beryl and most blue Tourmalines. Iron is the explanation all organic blue Spinels analyzed in this study showed magnetic attraction. All all-natural Spinels that experienced a ingredient of blue coloration or grey shade, like purple and violet Spinels, had been also magnetic. In addition to iron, cobalt is also current in blue Spinels, largely in trace quantities (<. 1% cobalt oxide by weight). The presence of cobalt in the gems we tested was confirmed by spectrometer analysis.Faceted spinel: Several pretty facet-cut spinels. It is easy to see how spinel can be confused with ruby and sapphire or used as an alternative stone. These spinels are about 4 1/2 millimeters in size and weigh a little less than 1/2 carat each. The top three red and pink stones were cut from material mined in Myanmar. Deep red spinel is rarer than ruby but sells at a fraction of the price. The blue stones below them were cut from material mined in Tanzania.All blue & red Spinels in our study showed some magnetic attraction, and on average, blue Spinels were twice as magnetic as other colors.
