Product Details & Shipping Details

Maximum Detailed Images Taken From Macro 85 mm Lens. Most inclusion visible in image not visible to naked eye. Cobalt Spinels are rare, and most blue Spinels that are marketed as Cobalt Spinels or “cobalt blue” Spinels are actually colored primarily by iron. When cobalt ions replace magnesium ions in Spinel, they produce only pure blue color rather than gray-blue or green-blue. Depending on the concentration of cobalt, color saturation can theoretically range from light blue to vivid blue. No ratio of iron to cobalt has been established to define what makes a true Cobalt Spinel, but logically, cobalt must either be the dominant cause of color or an equal contributor to color. This Cobalt Spinel is 3.64 Cts and its has a Beautiful Violetish Blue and its also has a Top luster, Its 100% eye clean. With CGJ Sri Lanka Cert.
