A diamond with a ratio of 1.40 would be 1.40 times wider than it is long when viewed from above. This would mean that the diamond is significantly wider than it is long, and may appear more oval or oblong in shape. The ideal ratio for a diamond is generally considered to be between 1.00 and 1.05, as this allows for the most light to be reflected and refracted within the stone, creating the greatest amount of sparkle and brilliance. Diamonds with ratios outside of this range may not have as much sparkle and brilliance, as the light may not be reflected and refracted as efficiently within the stone. However, the ideal ratio can vary depending on personal preference and the specific characteristics of the diamond. Some people may prefer a diamond with a wider or more oval shape, in which case a ratio of 1.40 could be considered attractive. It's important to keep in mind that the overall cut quality of the diamond, as well as its other characteristics such as clarity and color, also play a significant role in its appearance and value.
