What is a checkerboard cut gem?
In a checkerboard cut, a faceter cuts the gem with square facets, so its crown and table resemble a checkerboard. This cut is often used on translucent stones. Gem cutters craft varying facet shapes to manipulate a diamond’s sparkle. For a checkerboard-cut diamond, artisans use square or kite-shaped facets to produce a defined pattern much like the one you’d find on a chessboard or checkerboard (hence the name!).
113# blue color stones usually used as the simulated color of Sapphire blue stones. when you're looking for a cheaper alternative blue sapphire gemstones, Spinel 113# blue color is one of best choice.
What's Synthetic Spinel?
A: Although not as widely used today as synthetic Corundum, synthetic Spinel is still one of the most common man-made gem materials, particularly blue synthetic Spinel. It appears frequently in class rings and costume jewelry. Blue, green and other colors of synthetic Spinel are mostly manufactured using the inexpensive flame-fusion method by which the Spinel develops around an elongated boule. These flame-fusion Spinels can be distinguished from natural Spinels by a slightly elevated refractive index due to a chemical variation involving higher aluminum content.
Blue Synthetic Spinels of the flame-fusion type are typically colored only by cobalt. No iron is added, and therefore they are diamagnetic, another property that distinguishes blue flame-fusion Spinels from blue natural Spinels. When viewed under the Chelsea filter and also under long wave UV light, the light blue and medium blue gems pictured below left and center show a pale pink reaction due to low cobalt content, while the dark blue gem on the right appears bright red due to much higher cobalt content. None of the synthetic Spinels shown below contain enough cobalt to cause magnetic attraction.
