Product Detail:

The distinguishing features of natural and Synthetic
Green sapphires cut dark blue protolith to show the multidirectional color of green or blue-green on the front, then natural green sapphires can be formed. yellow-green and Gray-green sapphires can also be found on the market, but their value is relatively low. Most of the properties of synthetic green sapphires are the same as those of natural products. The refractive index ranges from 1.76 to 1.77, and the refractive index difference is 0.008. Both should be distinguished by magnification, ultraviolet (UV) light and spectrograph. At the end of the 19th century, the flame synthesis of Corundum has entered the jewelry market. By means of magnifying equipment inspection, it is possible to see bubbles in the flame synthesis of Green Sapphire Natural Green sapphires do not react under ultraviolet light, but green sapphires synthesized by flame method may react weakly orange under long wave ultraviolet light and dark brown-red under short wave. The Spectra of Flame Synthesis of green sapphires show characteristic absorption lines or bands at 670ー680 nm, and sometimes at 530 nm, and natural green sapphires have absorption bands at 450,460 and 471 nm. Different Spectral absorption modes are due to different chromophoric elements: Synthetic Green Sapphire is cobalt, natural iron and titanium. Hydrothermal Synthetic corundum is made in Russia. Unlike Flame Synthetic Sapphires, hydrothermal sapphires may have straight or angular growth lines, including mountain lines. Nickel is a typical chromogenic element in the hydrothermal synthesis of green sapphires from Russia. Green Corundum was synthesized by hydrothermal method using nickel to produce different polychromatic properties. Natural Green Sapphire is yellow-green, green or blue-green parallel to C axis, and blue-green to blue perpendicular to C axis Sapphire synthesized by Green Hydrothermal method is red-orange to yellow-orange parallel to the C axis and blue-green to yellow-green perpendicular to the C axis. Under magnification, it is possible to see filaments in natural green sapphires, rutile needles usually arranged in three 60 degree rows, other features found in natural products include: Boehmite needles with an angle of 90 ° , Zircon crystals with deep circular cracks, fingerprint-like inclusions, hexagonal growth lines, and color gamut.
