Sterling Silver Blue Sapphire 3.45ct Stud Earrings (925) Oval
This is a beautiful pair of blue sapphires cut in an oval design and set in sterling silver 925 stud earrings. The gemstones measure 7x5 mm and were cut by overseas faceters. Quantity each is one pair of earrings. These sapphires were created in a lab using the same chemical composition and physical properties as natural earth-dug sapphires. The biggest advantage of lab created gemstones is that these do not have the inclusions like most natural gemstones. This results in sparkling beauty from allowing light to pass into the stone and reflect out without imperfections to block the light. In other words, these synthetic sapphires have a flawless internal structure in most cases. A lab-created sapphire is a genuine sapphire, just one made under artificial conditions. Lab Created Blue Sapphire: General properties: Chemistry: Al2O3 Physical properties: Hardness (Mohs scale): 9 Crystal structure: triagonal Purity - 99.99% Identical to the Natural in Every Way.
