Synthetic Diamonds - Breakthrough Gem Material Bests Mined Diamonds And Moissanite Part 2 (synthetic diamond jewelry)

Can a jeweler tell the difference between a mined natural diamond and a synthetic polycrystalline diamond? (synthetic diamond jewelry)

All mined natural diamonds have structural flaws called inclusions. A competent jeweler under magnification can see that polycrystalline gemstones are perfect and void of birthmarks. That distinction alone should signal to a jeweler that synthetic diamonds are not mined natural diamonds. Most jewelry store counter salespeople, who often call themselves "jewelers," are not professional jewelers or gemologists and cannot tell the difference, and it is for that reason that many jewelry stores invest in scientific testing equipment. When a proficient jeweler in a retail store, not an inexperienced sales clerk, sees a synthetic diamond without birthmarks, he/she should be able to tell the difference without further testing. There are no reports from that anyone can tell the difference without close magnified scrutiny and years of expertise, or scientific testing equipment.(synthetic diamond jewelry)

Will polycrystalline synthetic diamonds test positive on a diamond tester, the kind a retail jewelry store would use? (synthetic diamond jewelry)

No, they will not. The heat signature is different and this is reflected when testing by a diamond tester. Diamond testers simply measure heat conductivity; they do not actually detect the presence of carbon. Thus, retail jeweler diamond testers are sometimes fooled by colorless sapphire and Moissanite stones. If you are buying Moissanite at $525 per carat solely because you believe it will test positive on a diamond tester, this is probably an error. You will find that no matter how long or how many times you wear diamond simulant jewelry out in public or out socially, that no one will approach you with scientific testing equipment and ask to test your gemstones.(synthetic diamond jewelry)
