As you mentally scroll down a list of possible gifts for the one you love you may forget to consider diamonds. So to answer the original question, what is the difference between costume and fashion jewelry, we must draw a very fine line of distinction. But personally, I prefer the term fashion jewelry as I want to be fashionable, not attired in a costume.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Proportions of the premium cut diamonds are very close to ideal cut. Premium cut diamond may be close to the ideal cut proportions and look just identical. By all means such diamonds are considered well cut. In fact, many consumers cannot distinguish between the ideal cut diamond and the premium cut. Appearance of diamond is very subjective and cannot be fully evaluated just by their proportions along.
Color F color diamonds are close to colorless. F color grade is rare and only surpassed by colors D and E. The naked eye will not detect any presence of color. For perfectionists, look for diamonds with low fluorescence.
Clarity VS1 clarity diamonds are very slightly included grade one. VS1 diamonds are less expensive than the VVS1 or VVS2 grades and present an excellent value. They have minor inclusions that are bigger and more noticeable than in higher clarity grades, but they are only visible at 10x magnification. To the naked eye, these diamonds will appear unblemished.
