A diamond with a ratio of 1.30 would be 1.30 times wider than it is long when viewed from above. This would mean that the diamond is slightly wider than it is long. Diamonds with ratios in this range may appear slightly more oval in shape when viewed from above, as the width is more pronounced compared to the length. 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. 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 slightly wider or more oval shape, in which case a ratio of 1.30 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.
