To make sure the gemstone is brilliant and radiance one needs to maintain its precious value, follow these recommendations.       The Shape Select a diamond’s shape that appeals to you or complements the personal style of your partner. Additionally, choose a setting, which provides security to a diamond with a particular shape. The Cut Make it a point that the gemstone has an ideal cut or excellent grading according to the scale by GIA. An exceptionally cut diamond is sure to maximize its fire as well as brilliance. The Clarity It is worth narrowing down your search for three-carat diamond rings to those with VS1 and VS2 clarity grades. They offer the best value while keeping the inclusions to a bare minimum. If you choose diamonds with these grades, inclusions and blemishes will not be easily noticeable. The Color Consider diamonds that fall under the nearly colorless range from G to I. These diamonds appear as clear as the gems in the D to F color scale, but will not cost as much.
