Shopping for a fancy shaped diamond other than the classic round cut brilliant stone for your engagement ring is really a hard decision to make. There are a lot of diamond shapes available in the market, which includes radiant cut, oval cut, emerald cut, cushion cut, princess cut, and many other fancy shapes. The thing that is common to all these shapes is that they all have a great range of faceting styles and proportions. From this, you would be able to clearly understand that, taking just a look at the diamond certification would not give you a clear idea about how the diamond actually looks.
Taking into account the table and depth are not the only matter of concern; you would also have to ponder on many other factors of the stone. That is because the characteristics of the diamond would change even with a small change in the clarity and color. In short, the factors differ with each of the individual stone. Below is a compilation of things to consider while searching for beautiful radiant cut engagement rings along with its GIA report.
The date of the GIA report may sound least important to many; however, there is a lot of information hidden in this date. The date mentioned in the GIA report is actually the same date when the GIA laboratory graded the diamond. Even if the diamond, which you have purchased is of good quality, this would not mean that it would have a long shelf life. If the diamond with a date that is under one month means that it is quite new to the market.
This does not mean that you need to get a diamond with a date that is less than one month; it would be fine even if the diamond is certified by the last two years. By considering this factor, you would be able to make sure that the diamond you are purchasing had not been passed down through the hands a series of customers.
The measurements of the diamond are a very important factor, as this would influence the appearance of the stone. Just as carat weight is a crucial part of the diamond, considering other measurements are also likewise important. The first measurement is that from the top to the bottom of the diamond and the second measurement features the diamond width. If you divide these ratios, you would be able to get an idea on the shape of the diamond whether the stone is in a square or rectangular shape.
Assume that the measurement of the diamond is 9.46 x 6.88. This means that the stone would be very large and would weigh over three carats. However, before running into final assumptions, you would also have to check the depth of the diamond and make sure that the diamond is not too thin. The next thing to consider is the length-to-width ratio. If the length-to-width ratio of the diamond is 1.37:1, this means that the diamond is elongated. The most standard and accepted length to width ratio for an elongated radiant cut stone is 1.15:1 which could go as far as 1.40:1. This would be best suited for people who prefer their stone to fully cover their finger or give it an elongated look.
Depth and Table
You could also find the depth/table percentages in the GIA report. This value would vary with each diamond shape. This value is also really important while choosing the perfect radiant cut stone. If the table of the diamond is extremely large, this would mean that the stone would be in short of fire and sparkle. Furthermore, if the depth percentage is very small, this means that the stone is extremely shallow and would not be able to reflect much light. In addition, if the depth percentage of the radiant cut diamond is above 70, this means that there is a hidden weight, which lies within the stone. This could make the stone look smaller.
Carat weight is one of the most important things to decide on while you start your search for diamonds. However, you would also have to keep in your mind that the weight of the stone would only point out the face-up size of the diamond. One of the common procedure followed by most people while shopping for their dream diamond ring is that they would buy the stone only taking carat weight into account and would not consider any other measurements of the stone.
Most of the round cut diamonds come along with a standard value of carat weight. However, fancy diamond shapes come in a wide range of carat weight measurements. The carat weight of the diamond would also directly indicate the rarity of the stone. The GIA would round up the carat weight only if the last thousands place digit of the carat weight is 9.
