Another good clue to dating a piece and determining the value of Antique and Vintage Jewelry is to look at the metal content where there might be some underneath wear, usually in back where it would rub against the clothing. During the war years of the 1940s there was a shortage of base metals where it affected the jewelry industry so sterling silver was substituted.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds of premium cut proportions are almost as good as ideal. Most people will not be able to distinguish an idea cut from premium. Less diamond material is lost in the process of cutting thus making the diamonds less expansive then ideally cut ones. In short premium cut reflects almost as much light as the ideal-cut, but for a lower price.
Color E color diamonds are virtually colorless. E color grade is very rare. The naked eye will not detect any presence of color. E color grade is indistinguishable from D without instrumentation.
Clarity The stones of SI2 clarity have inclusions which are fairly easy to see under a loupe with 10X power magnification. Such inclusions may be visible to an unaided eye depending on their location. SI2 clarity diamonds of G or H color look nearly perfect when mounted. For those looking for near perfection these sure come close.
