What to Consider when Choosing a Yellow Diamond for Your Jewellery?

22 Sep 2020 7:13:00 pm

Yellow diamonds are a popular option even amongst coloured diamonds. The bright yellow tint gives it a distinctive look and makes it coveted, even more than clear diamonds. 

Just like clear diamonds, yellow diamonds are also formed over millions of years. They are also subjected to pressure under the earth’s crust. However, their clarity is affected by nitrogen molecules and this is what gives it the yellow tint. 

Yellow diamonds are the most common type of coloured diamonds. They make 60% of the total coloured diamonds in the world. Nonetheless, coloured diamonds are anyway found seldom while mining. Therefore, yellow diamonds are pretty rare.

When it comes to selecting yellow diamonds there are several things that need to be taken into consideration in order to make the right investment. These are as follows:

Color Grading

  • D-Z Range for Natural Diamonds

When it comes to diamonds, the general colour grade used for colourless varieties is D-Z. Here, D stands for the most colourless and Z stands for the one with most colour. Often colourless diamonds get a slight yellow hue and start shifting towards the Z grading. In such cases, the Z graded diamond costs less than the colourless D graded diamond. Nevertheless, it's important to remember that Z graded colourless diamonds usually have a very light yellow tint. This is what is called a natural yellow diamond. Diamonds with colours that fall beyond the Z range are categorised as fancy diamonds.

  • Range for Fancy Diamonds

Fancy diamonds is the term used to describe coloured diamonds with a hue that falls beyond the Z range. It usually falls between eight grading categories. These are: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Dark, Fancy Deep and Fancy Vivid. When it comes to yellow diamonds, the first three categories are generally invalid. A yellow fancy diamond grading starts from Fancy Light and goes on to Fancy Vivid. The price increases as the colour intensifies, unlike natural yellow diamonds. 

Four Cs

All diamonds are usually evaluated on the basis of 4 main things. These are colour, carat, cut and clarity. When it comes to yellow diamonds, these 4 elements apply as follows. 

  • Colour: 

As discussed earlier, a yellow diamond that is graded as a fancy diamond will cost much more than the natural ones that usually have a very faint yellow undertone. Among fancy yellow diamonds, the fancy intense variety will cost less than the fancy vivid one. A fancy vivid diamond will also be graded higher. Although, before grading, GIA also looks at aspects like hues, saturation and tone when determining the price of coloured diamonds. Hue refers to the primary colour of the diamond, the rarer this is the more the diamond is priced. Saturation determines the intensity of the coloured diamonds. A fancy vivid yellow diamond is more intense in colour than a fancy dark one. Therefore, the former will be priced higher. A tone determines how dark the hue of a diamond is. Sometimes a diamond may appear patchy due to an imbalance of colour distribution. In such cases it will be priced much lower. A tone that isn’t too dark or too light and underscores the main hue of the diamond is generally preferred amongst fancy yellow diamonds. 

Yellow diamonds may also be affected greatly by fluorescence. Fluorescence is the glow that a diamond emits. When seen under a source of ultraviolet light such as the sun, certain yellow diamonds may fluoresce. They may emit a bluish light. In such cases, very faint coloured yellow diamonds in the category of I to M may start looking more colourless. These will be priced higher. Although, fluorescence may sometimes affect D to H diamonds in a negative manner by making them look oily or hazy. In such cases they will be priced lower. In fancy yellow diamonds, fluorescence usually enhances and compliments the colour, giving it a distinctive tone. Therefore, fancy yellow diamonds that fluoresce more will be priced higher like with natural yellow diamonds with a higher grading than H. 

  • Carat: 

Usually, when it comes to colourless diamonds, the higher the carat the more is the price of a diamond. In coloured diamonds, this difference between price might be exorbitantly high. Therefore, a yellow diamond of 1 carat will cost much less than a yellow diamond of 2 carat weight. This is generally due to the fact that coloured diamonds of a higher carat are quite rare. 

  • Cut:

Cut has a very less significance when it comes to yellow diamonds. The thing to consider is what cut makes its colours the most visible. A cut that helps the hue of the yellow diamond come out the best should hence be chosen. 

Normally, amongst yellow diamonds, a round cut is less preferred. This is because the yellow diamond will show more face up colour when cut in another shape than round. Fancy shapes such as oval, pear, marquise, heart, emerald and so on are more preferred amongst yellow diamonds. 

  • Clarity:

Clarity is of least important consideration when it comes to yellow diamonds. This is because the colour in the fancy yellow diamonds usually hides impurities underneath. These cannot be detected unless seen under a magnifying lens. A yellow diamond that isn’t at par in clarity with a colourless one will thereby cost the same, or more depending on the colour intensity, despite being graded differently. 

Certification 

If you are set out to buy a yellow diamond, checking if it has been graded by the GIA is important. This is because GIA is trustworthy and will also specify if the coloured diamond has gone through high pressure, high temperature annealing to artificially increase its colour intensity. It will price these lower than naturally available fancy yellow diamonds. Similarly, a yellow diamond coated with colour or grown in the lab will also be graded differently by the GIA. Other certifiers and luxury groups can dupe you into buying a lower quality yellow diamond for higher prices.

Choice of Metal

When it comes to coloured diamonds, the choice of metal is very important. It determines how your diamond will look in a jewellery setting. Usually, if your diamond is vibrant, a contrasting platinum setting would make it shine out. On the other hand, if it is light, a gold setting will enhance its vibrance. For medium range fancy yellow diamonds, a rose gold setting works perfectly. Determine the colour range of your diamond and choose a metal accordingly.
