7 common mistakes when purchasing a diamond

Diamonds are a lifetime investment, the grandest of gestures, and most importantly, a girl’s best friend. Purchasing this precious rock is a decision that should not be taken lightly, and you should pay the right care and attention in order to find the perfect stone for you. The Diamond Room team has helped many customers make informed decisions when they are choosing stones or creating their jewelry. Our experts have extensive knowledge concerning the best practices to make when searching for diamonds, and will help you not make these 7 common mistakes when purchasing a diamond.

 

Here are some of the common mistakes you should avoid when deciding on your next purchase:

 

1) Ignoring the fundamental 4 C’s of Diamond Purchasing

One of the biggest mistakes made by our clients is ignoring the essential 4 C’s, also known as Cut, Colour, Clarity, and Carat. This grading system is used globally in the industry, allowing experts to use a diamond’s best-defining features to determine the stone’s value, quality, and rarity, making it a handy tool for customers aiming for quality assurance in their purchase.

 

2) Choosing a poor quality cut

The quality of the cut in your diamond can be the deciding factor in you landing a show-stopping piece or getting stuck with a dull rock. A well-cut diamond is designed to shine, sparkling at every angle upon exposure to light. A poor-to-fair cut will appear dark, losing its glisten to steep crowns and pavilion angles.

3) Using Carat weight as the sole deciding factor

When it comes to sparkles, bigger is not always better. Carat weight is used as a benchmark for measuring the value of a diamond, with higher weights of 1.0-1.9, drawing heftier price tags. This measurement, however, does not always reflect true Diamond quality. Heavier stones may result in higher costs, but they do bring with them a range of poor cutting styles and imperfections. Customers should always remember to use the cutting style as the initial deciding factor in all Diamond purchases, before weight or the other C’s.

4) Purchasing a Diamond before understanding The GIA Colour Scale

When you think of Diamonds, you may be drawn to picturing the glistening glow of a colorless gem. From tranquil blues to passionate reds, Diamonds come in all colors of the rainbow, and this can be a large influencer on price. A fully colored Diamond is an odd rarity found in stones that have faced impurities and structural defects, resulting in coloration. Pure diamonds are still the most popular stone of choice, and with demand comes inflated values.

Diamonds are graded on color using the Gemological Institute of America (GIA) color scale. This scale classifies each stone with a letter between D, and Z. D means the least color, increasing in color to Z, meaning the most color. You can find out more regarding color guidelines and rating on our website:

 

5) Searching for a Diamond with no imperfections

Perfect diamonds are rare to find, and many jewelers can go their entire career without ever discovering one. The majority of stones will come with imperfections, although most are only discoverable under magnification. Unlike the color and weight scaling processes, reviewing clarity requires understanding the entire grading system, leaving customers confused and unable to do this ‘C’ independently. There are four key terms to understanding Diamond clarity: 

 

Inclusion – markings or issues on the inside of a diamond. Inclusions occur due to irregularities in the growing process.

 

Blemish – any imperfections or issues on the outside of a diamond. Blemishes occur due to mistakes during the cutting, mounting, and polishing process. You can also cause blemishes on a diamond while wearing it.

 

Eye Clean – The imperfections of a stone that are too small to see with the naked eye. (Though they can be seen under magnification).

Brilliance – The white light reflected from a diamond. Brilliance is part of what makes a diamond sparkle.

 

Blemishes and inclusions will hurt a diamond’s brilliance and can even affect the overall visual beauty of the stone. Customers are advised to educate themselves on the clarity grading scales to avoid falling for a stone riddled with unforgivable imperfections. Our team explains the diamond clarity scale in a detailed ‘Clarity expert guide’.

 

6) Not examining the setting of a stone

Diamonds can last a lifetime, but the diamond’s setting is key to keep the stone from falling out. Setting a diamond is a delicate and challenging process carried out by professional setters to ensure your precious gem stays firmly in place without interfering with the piece’s overall design. A fine balancing act between structure and style, setters will aim to provide a flawless product with as little material as possible, securing the stone in a complimenting fit. A poorly fit diamond may withstand a few years of general use but will pose a risk of becoming loose in later life. Customers can also test designs before purchase, aiming for good quality materials and reputable stores to avoid expensive troubles arising in the future. 

 

7) How to test a Diamond’s setting

The type of diamond you will purchase will determine how you test the setting of a stone. Four or six-prong settings can be checked by applying your fingernail to the stone’s girdle. If the diamond sits firmly in position, the set is secure. If you can’t access this area of the stone, which is more common in bezel setting practices, use a pin to try to press against the diamond to check for movement.
