The uniformity and beauty of the color of whether precious, semi-precious stones and diamonds is a primary determinate of quality and value. Color is graded on the strength of tone, with a stronger tone commanding a higher price. Color can vary sharply depending on the origins of the stone, and in turn affects its value.
Gem laboratories, jewelers, and manufacturers coined words to describe color of stones and diamonds. Such in the case of yellowish and brown diamonds, words like champagne, cinnamon, chocolate, honey, cognac, caramel, nutmeg, butterscotch, espresso, clove, gold, etc. sounded far better than “faint-color”, “yellowish” or “brown”.
Words and the color they denote are as follows: Ginger denoting yellow brown, Champagne is a golden yellow brown color, Cognac refers to yellowish brown, Gold refers to intense yellowish brown, Canary is just like a canary bird whose color is brown and yellow, Chocolates denotes dark brown, Chocolate orange is a dark orangy brown, and Olive which refers to brownish green.
Other words denoting colors include Cherry for red, Snow for opaque white (not clear), Bottle green denotes dark green, usually used to describe tourmaline, Grass green for green garnet or tsavorite, Ice blue which is a very light blue sapphire, Sky blue which is a bit darker than ice blue, Cornflower blue which is a deeper blue than sky blue, and so much more.
The term fancy is a deeply saturated stones and diamonds. True natural fancies are rare and expensive. The color of fancies are more deeply saturated colors, rather than faint or pastel shades. They derive their value from the quality of their color. GIA grades fancies using specific gemological language to describe tone, saturation and hue. It is possible to have a fancy diamond, but not every diamond has the color of a fancy. The GIA grading system ensures a precise color description.

Brown diamonds are an acquired taste. Nevertheless, soon, they will become a required taste. Aesthetics has nothing to do with it. Fancy brown diamonds are the most competativly priced stone left in the diamond world. This colour diamond is about the same price as commercial-grade, 1-carat colourless diamond. Even though brown diamonds are so very rare, the consumer would fair far better financially and profit more by choosing a brown diamond over a very commercial white diamond.
It is important to note, however, that the one carat, fancy brown, round cut, with the clarity grading of VS1 has gone up in value by 20% over the past three years. It may even reach a 30% increase this year! That is one of the main reasons why this magnificent diamond has such an impact in the market recently. Not only that, but De Beers, the diamond giant, is mindful of the fact that fine browns have been attracting more attention, since they control most of the world’s diamond supply. This is another reason this diamond is definitely making its importance known.
The diamond industry in the recent times has become one of the largest and most profitable industrial sectors in the world investment market. Hence, diamond trading has become a profitable profession these days.
Diamonds are not as liquid as other kinds of investments, but in tough economic times, it is important to focus more on the preservation of capital and less on increasing financial gains. Fancy coloured diamonds offer a unique source of value for those who chose to invest in them.
Brown stones are categorized in three fancy colour designations: “fancy” (the colour of milk chocolate), “fancy light” (the colour of ginger ale), or “fancy dark” (the colour of dark coffee).
Brown diamonds are gaining popularity amongst women although they still have a preference for traditional whites and the beautifully elegant pink diamonds in today’s market. However browns have become more appealing to men, making them feel more comfortable about wearing diamonds. The colour guarantees a man can keep his ‘masculine image’, according to one dealer. He also states that browns are ideal for men.
The term “fancy” before “brown” helps to place the brown diamond in the fancy diamond league. The presence of a secondary colour, namely yellow or olighten only serves to increase their desirability.
Keep in mind that profitability of brown diamonds is on the increase today. This holds their importance in the market.

In recent decades, gemstones sales have been heavily tilted toward colourless diamonds. This phenomenon has created consumers and dealers who do not wholly understand the underlying points of value between different kinds of colours in stones. Understanding how coloured stones and colourless diamonds should be valued lead to effective marketing and eventually remarkable sale of coloured gemstones and natural coloured diamonds.
The basic framework for judging the value of colourless stones is known as the 4C’s. The 4C’s are Carat, Cut, Colour and Clarity, which the latter refers to the stone’s brilliance. Taken to consideration this basic framework, a novice consumer can understand that the larger the carat, better the cut, cleaner the stone and more intense the colour, the more the stone is worth.
A carat is a type of measurement use to describe the mass or weight of a gem. As a general rule, the bigger the stones the more valuable it is than smaller ones.
The complexity of the cut does not affect the refractive beauty of colored stone in the same way that it will for a colourless diamond. In other words, a simple cut can showcase the high points of a coloured stone just as well as a complex cut as colored stones have their own natural glow known as luster or fire. In diamonds however, a higher number of facets will not influence the values of the stone, but may be a contributing factor for selling.
The uniformity and beauty of the colour is a primary factor of quality and value. Colour is graded on strength of tone, with a stronger tone commanding a higher price. An important factor of origin on color however affects the stone’s value. This criterion of origin is more important in rubies and sapphires than in natural coloured diamonds. Nevertheless, to be able to quickly and concisely explain the value points of a given colour and regional source is another contributing factor in influencing sales.
Clarity refers to the purity of the stone and the lack of inclusions. It is worth noting however, that inclusions in coloured stones can be measured by the naked eye, unlike with colourless diamonds which is measured at 10x magnification. In some stones however, inclusions may actually be highly valued depending on their shape and placement. A perfect example is a star shaped inclusion, known as asteria. This can actually enhance the value of some stones, especially sapphires and emeralds. These stones almost always have inclusions, especially in their larger form, that do not essentially devalue the stone.

Due to marketing and trade patterns, there is a bit of competition between traditional gemstones and coloured diamonds.
Supply is definitely a factor. In one of the estimates, it is said that less than 2% of all gemstones are can be considered fancy coloured diamonds, while white and colourless diamonds are so common that they are considered mass market consumer goods. This is especially true among smaller carat sizes.
The rarity of fancy coloured diamonds allows for some of them to go for more than £100,000 per carat. In fact, at private invitation on auctions by some of the mines, bids of more than £200,000 have been reported for fancy pink and reddish coloured diamonds. It has been a passionate fight among connoisseurs for such stones as they are widely regarded as the non plus ultra of status symbols.
Top gemstones are sold at equally high amounts as well. Like in the case of rare rubies, especially Burmese stones of three carats and above will only be made available at specialty auction events with prices rivaling that of the pink diamonds.
As in the case of rare and truly real Kashmir sapphires, pegged at £100,000 per carat when they are available in the market at all. Tiffany and Christie auctions continue to push the mark higher for these stones whenever they appear. Even in the 2 – 10 carat range of brown and chocolate diamonds compete fiercely for the market share against emeralds and sapphires.
In the end, the ultimate winner is the consumer who has a unique piece of jewellery and the retailer who keeps a healthy mark up on the stones due to the lack of price list for direct comparison. Since coloured diamonds can’t be as exactly graded as expensive colourless diamonds, their value is more volatile.
