How to Choose a Blue Diamond: Rare, Natural and Expensive

How to Choose a Blue Diamond: Rare, Natural and Expensive

You might think that colourless diamonds are the most expensive and sought after stones available on the market, but some coloured diamonds are much more expensive and even harder to find. Such is the case with blue diamonds which are beyond the reach of most of our budgets. Let’s take a detailed look and find out how to choose a blue diamond.

HOW TO CHOOSE THE COLOUR OF BLUE DIAMONDS

Natural blue diamonds owe their colour to the rare chemical element boron, which makes up only about 0.001% of the earth’s crust.

The diamond gets blue colour if the nitrogen content is low and there is boron present in its chemical structure. The higher the concentration of boron, the more intense the blue colour. The darker the blue, the more expensive the stone.

According to the GIA blue diamonds are classified using the following colour grades: Faint Blue, Very Light Blue, Light Blue, Fancy Light Blue, Fancy Blue, Fancy Intense Blue, Fancy Vivid Blue, Fancy Dark Blue, and Fancy Deep Blue. The secondary hue is also included in the grade if it is present, for example, Fancy Greenish-Blue.

Blue Diamond Colour Grades

The colour evaluation of blue diamonds has three main components: hue, saturation and tone.

HUE

Hue is the visible colour of a diamond and the primary hue of blue diamonds is blue.

There can also be secondary hues which greatly affect the value of stones. The most common secondary hues present in blue diamonds are green and grey.

Secondary hues that enhance the primary hue or do not detract from it add the value as a rule. Natural blue diamonds with no secondary hues are extremely rare and pricy.

SATURATION

This characteristic refers to the intensity of the colour.

As a general rule, the more saturated the colour of a diamond, the more valuable it is. That is why the diamonds that have pale or faint blue colour are less valuable than those with deep and vivid blue colour.

TONE

This characteristic refers to how light or dark the colour is.

The choice of the tone depends on your personal preference, however, the stones that are somewhere in the middle are the most sought-after.

The colour grade of blue diamonds is assigned based on saturation and tone.

HOW TO CHOOSE THE CLARITY OF BLUE DIAMONDS

The clarity of blue diamonds is graded the same way as that of colourless stones. The fewer inclusions, the higher its clarity grade.

Of course, high clarity blue diamonds are more valuable, but this characteristic is not crucial for fancy coloured diamonds. The blue colour tends to hide imperfections, so the appearance of blue diamonds is less affected by flaws compared to white diamonds.

When choosing the clarity of blue diamonds, look for a stone that is eye clean, meaning the diamond should not have inclusions visible to the naked eye.

Blue diamonds in the SI1-SI2 clarity range may look stunning and do not differ significantly from diamonds in VS or even VVS range.

HOW TO CHOOSE THE CUT OF BLUE DIAMONDS

Unlike colourless diamonds, blue diamonds are not cut to maximize brilliance and sparkle. Blue diamonds are cut to achieve the best colour possible. In other words, the proportions that are considered ideal for colourless diamonds will not always be the best to bring out the colour of blue diamonds.

So when choosing a blue diamond, you should focus more on the stone’s colour intensity and hues, rather than judge the diamond using traditional cut grades.

BLUE DIAMONDS AND CARAT WEIGHT

Blue diamonds are extremely rare and they are among the most expensive coloured diamonds on the market. A good quality 1-carat blue diamond can cost up to $100,000.

Bigger blue diamonds are even harder to find, which is why they cost disproportionally more per carat.

As you increase in colour intensity, blue diamond prices extend beyond $200,000 per carat. Certain colour combinations such as blue diamonds with grey secondary hue are more affordable, they cost in $30,000 – $40,000 range.

Managing Coronavirus (COVID-19) Anxiety

Quarantining yourself at home can play an important role in preventing the spread of infectious diseases. But this doesn’t mean that coping with the disruption in your normal routine is easy. Taking care of your mental health is essential, even if your time in quarantine is relatively brief in the grand scheme of things.

For you:
- Avoid excessive exposure to media coverage
- Connect through calls / text / internet
- Add extra time for daily stress relief
- Practice self-care
- Focus on your mental health

For kids:
- Reassure them that they're safe
- Let them talk about their worries
- Share your own coping skills
- Limit their news exposure
- Create a routine & structure

For quarantine / isolation:
- Keep in contact with your loved ones via social media, texts, and phone calls
- Create a daily self-care routine
- Keep yourself busy: games, books, movies
- Focus on new relaxation techniques

For responders:
Responding to COVID-19 can take an emotional toll on you, and you may experience secondary traumatic stress.
- Acknowledge that secondary traumatic stress can impact anyone helping families after a traumatic event.
- Learn the symptoms including physical (fatigue, illness) and mental (fear, withdrawal, guilt).
- Allow time for you and your family to recover from responding to the pandemic.
- Create a menu of personal self-care activities that you enjoy, such as spending time with friends and family, exercising, or reading a book.
- Take a break from media coverage of COVID-19.
- Ask for help if you feel overwhelmed or concerned that COVID-19 is affecting your ability to care for your family and patients as you did before the outbreak.

Taking care of yourself, your friends, and your family can help you cope with anxiety. Helping others cope with their anxiety can also make your community stronger.
