VVS2 inclusions are very difficult to locate even at 10x magnification. In a marquise, VVS2 is clarity well beyond what the eye can see; you are paying for rarity rather than a visible difference compared with VS grades.\u003c\/p\u003e\u003ch3\u003eHow F VVS2 compares with nearby grades\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eE VVS2, one color grade higher: a slightly whiter stone, though the difference is only visible side by side.\u003c\/li\u003e\n\u003cli\u003eF VVS1, one clarity grade higher: fewer and smaller inclusions, invisible without magnification either way.\u003c\/li\u003e\n\u003cli\u003eF VS1, one clarity grade lower: slightly more inclusions under magnification, typically still eye-clean.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eHow big is a 4.5 carat marquise?\u003c\/h3\u003e\u003cp\u003eAt 4.5 carats the diamond is unmistakably grand, a true heirloom-size stone. This stone measures about 16.5 x 8.3 mm.  For comparison, a 4 carat marquise measures about 15.7 x 7.9 mm; a 5 carat marquise measures about 16.9 x 8.5 mm. Elongated shapes spread their weight over a longer outline, so a 4.5 carat marquise faces up larger than a round of the same weight. Colorless grades keep the tips icy.\u003c\/p\u003e\u003ch3\u003eQuestions about this diamond\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs a 4.5 carat marquise F VVS2 eye-clean?\u003c\/strong\u003e\u003cbr\u003eIt is eye-clean.
