Price and Value of a Natural Polished Diamond

March 13, 2024


Diamond value

 We all know that diamonds are highly valuable, whether they are white diamonds or colored diamonds, it’s not like buying something on Ali Baba, but what makes them so expensive? The rarity of diamond colors has a direct effect on the price, and so does the clarity cut and polish grades which affect a real diamond in sunlight, real diamond vs fake diamond affects price as well. So let’s dive into what makes the most expensive diamond, but also the prettiest diamond. We will talk about what makes diamonds reflect or shine.

 What affects the “bottom price” of a natural diamond, most of all a direct result is the size or carats in this case. The cartage of a diamond ultimately reflects the price of the diamond taking into account all other criteria; this is what we want to tell you about.

How diamond is polished

 First I'd like to talk about how a natural diamond is "built", so let me try to simplify it as much as we can. Rough diamonds come in different shapes, the shape of the rough determines what cut/shape the rough will produce, this is done by highly professional cutters, however, these days there is also technology that helps diamond polishers determine what shape will be polished from the rough, here is where it gets interesting. Polishers want to get the most out of the rough, meaning they would want to get the highest return on investment, the polishers lose rough in the polishing process, say they have a 1ct rough natural colored diamond, when the polishing of the natural diamond is complete they be left with 0.50ct natural diamond, so they've "lost" half the carat weight during the process. This leads polishers to try and minimize the "loss" by producing a natural diamond as close as possible in size to the original rough. It's at this point that money and art collide. We all know the joke that when bankers get together all they talk about is art, but when artists get together all they talk about is money. I like this analogy because same as the artists when they are making art they are not thinking about how much paint, canvas, film or clay they are using, they are only thinking of making a masterpiece, and the bankers are only thinking of the bottom line, how much money will they make at the end of a business endeavor.

Art of polishing

 Polishing a natural colored diamonds is an art, but these days I feel the polishers are more like bankers than artists, now we don't mean to offend anyone, making money is an art all on its own, but I've seen plenty of diamonds that were polished with more money in mind than art, let me explain.

 To explain ourselves we want to go back to how a natural diamond is "built" and the size/carat of diamonds, in short, a rough diamond is polished down to its girdle, crown, pavilion, table, and more but these are what we want to elaborate on.

 These criteria determine the carat weight of the natural diamond. The thicker the girdle the more carat weight it “holds”, in pavilion and crown it’s the angle that determines how much carat weight the natural diamond or colored diamond will be, the shallower the angle the more carat it can “cram” into the natural diamond. Now that we have learned how the diamond is built we can understand the depth of a natural diamond, given the girdle thickness crown plus pavilion angle and diameter of the natural diamond we can determine the depth of the diamond. This is the key factor we would like to come to, now we all want a big diamond, not a thick one. Of course, the beauty of a natural colored diamond or a colorless diamond is somewhere in between not being too “shallow” which gives a fisheye effect that decreases the sparkle – which directly affects the beauty - and not being too thick which makes the diamond weigh more in carat – which directly affects the price of the natural colored diamonds and white diamonds alike.

Here are two examples, one is a “heavy” make, common with natural colored diamonds, and the second is a dazzling work of art, somewhat rare in colored diamonds;

 So when we see a natural colored or colorless diamond we like to see the total depth of the diamond compared to the table percentage, if a diamond has higher table percentage than total depth that means the diamond’s carat weight is spread well, but we must make sure that the diamond is still sparkly, because if a diamond is too “shallow” it loses its sparkle, the magic is finding a diamond that is just thick enough to give maximum sparkle without causing it to be too heavy therefore a valuable diamond. If we see a natural colored or colorless diamond that has a higher total depth percentage than the table, we call this a heavy diamond; for instance, a 3ct natural diamond could have the diameter of a 2.5ct natural diamond, and so forth, however, this is not the case in rectangular shaped diamonds, as in these the depth is usually greater than the table due to the mathematical way of calculating.

 This is why our specialist handpicked these diamonds, they are full of sparkle and life, and they have been polished with art in mind and in such a way to keep the diamonds sparkle at the maximum yet making sure they look very big.

Art comes to life

 The first natural diamond you see is a Cushion cut 4.23ct L color, with total depth of 55% and table of 64%, our diamond looks so big with measurements reaching 11.60mm, some 5 and 6 carat diamonds don’t reach these measurements. Large natural L color diamond with a hint of brown and a haze of pink, GIA certified diamond, with top clarity and full of luster. Our specialist handpicked this diamond due to its unique appearance; it is a spready diamond making a 4.23ct look like a 5ct. you won't find another like it, clean fiery and big. When a diamond has low depth that means all the diamond weight is concentrated in the table, which means the diamond looks bigger for its category.

 The second diamonds you see are round brilliant-cut diamonds that were chosen due to their rare size and colorless appetence. Finding diamonds between the sizes of 0.95-0.99 is rare. Furthermore, unlike most diamonds of this size, our diamonds have the proportion of a 1ct diamond (over 6mm).  1ct diamond will have a 30% jump in price. So you are buying a 0.96ct diamond that actually looks like a 1ct - that's value and art together.

Rest assured that by buying these natural colored diamonds and colorless diamonds you are getting the most for your investment, it’s like getting a diamond for cheap plus you get to enjoy it forever, it never loses its sparkle, and always looks like the day it was just polished, and after you take it to a jewelry cleaner machine even more and most of all will always be the center of attention for generations to come.
