Choosing the best shape for you
When it comes to shape, it is simply comes down to personal preferences,, and what looks best on your hand. Longer and shorter stones can visually affect the appearance of your hands, making them look longer or shorter in return. Also, your taste may guide you toward more traditional shapes, like the classic round brilliant, or toward less conventional shapes like pear, marquise or heart.
While the shape of the diamond you choose is ultimately a matter of personal preference, there are differences in the various shapes that affect their brilliance, apparent size and value:

Its design allows it to hide flaws and yellow tints better than diamonds of other shapes. In emerald cuts and baguettes, which have long, flat facets, flaws become the most obvious
Emerald cuts, while sleek and attractive, are not quite as brilliant. If you like the square or rectangular shapes of an emerald cut, you may want to consider a radiant, princess or quadrillion, which have more facets and therefore more brilliance.
If you want a diamond that looks as big as possible, even if it doesn’t weigh much, consider a fancy shape like a marquise or pear, which appear bigger and longer than round diamonds of the same carat weight.
