What’s Synthetic Spinel?

Synthetic spinel, was first produced accidentally during an attempt to make a satisfactory blue synthetic sapphire by the Verneuil process. Instead of the blue sapphire they discovered synthetic spinels like Synthetic Aquamarine. These lab created Blue London Blue Color Gemstones are exact copy of their Natural counterparts. The real London Blue Topaz is expensive but the good quality synthetic Blue Zirconia London Blue spinel is very cheap in comparison.

Synthetic spinel is widely used because it is slightly softer than synthetic corundum, it can be fashioned more rapidly and less expensively. Secondly, several of the colors in which it is made are better imitation for a number of natural stones than those made in Synthetic corundum.
