The Ultimate Guide to Diamonds: Unveiling the Beauty Within

At Powells Jewellery, we understand that choosing the perfect diamond is a deeply personal and meaningful experience. To assist you on this sparkling journey, we present our ultimate guide to diamonds, exploring the renowned "Four Cs" and sharing our expert insights to help you make an informed and confident choice.


The cut of a diamond is very important for its sparkle and brilliance. Our curated selection showcases diamonds with exquisite precision and craftsmanship. From the classic round brilliant to fancy shapes like cushion, emerald, or pear, each cut has its own unique allure. We prioritize diamonds with excellent or ideal cuts, ensuring maximum light reflection and captivating beauty.


Diamonds are formed deep within the earth, and their journey leaves behind nature's unique imprints. Clarity refers to the presence of internal or external characteristics known as inclusions or blemishes. Our selection features diamonds with exceptional clarity, offering unparalleled transparency and captivating beauty. Whether you seek a flawless diamond or prefer the character and charm of a slightly included stone, we guide you to find the perfect match.

Carat Weight

Carat weight is literally the weight of the diamond, measured in Carats (ct), 1ct is broken down as 100 points. Our collection presents a range of carat weights to suit every preference and price range. We believe that the true beauty of a diamond lies not only in its size but also in the craftsmanship and quality that Powells Jewellery upholds. Our team is dedicated to helping you discover the perfect diamond that embodies both size and quality.


Diamonds come in a spectrum of captivating hues, ranging from pure white to fancy colours like yellow, pink, or blue. At Powells Jewellery, we offer a variety of diamonds across the colour spectrum, allowing you to select the shade that best reflects your personal style. Our expert team meticulously grades each diamond, ensuring transparency and authenticity in our collection.

The colour of a classic white diamond, graded on a scale from D to Z, reveals a rich spectrum of enchanting hues and nuances. Let us take you on a journey through the various shades of white diamonds, each with its own unique charm and allure.

Dazzling White Diamonds (D-F)

In the realm of white diamonds, the D-F range is where pure brilliance resides. These diamonds showcase an immaculate and colourless beauty, reminiscent of glistening ice.

Near-Colourless Diamonds (G-J)

Moving along the colour spectrum, we enter the realm of near-colourless diamonds. Within this range, G-J diamonds exhibit a delicate balance between subtle warmth and exquisite brilliance. These diamonds boast a soft, romantic glow that beautifully complements a variety of settings. Their understated elegance and versatility make them a popular choice for those seeking a refined yet affordable option.

Warmth and Character (K-Z)

As we explore the latter half of the colour spectrum, often more common in vintage and antique jewellery, we encounter diamonds with captivating warmth and character. Diamonds in the K-Z range display subtle hints of yellow or brown tones, creating a unique and distinctive appeal. These diamonds possess a warm and alluring charm, offering a touch of individuality and personality. With their distinctive character, these diamonds make a statement of their own, celebrating the beauty in their inherent uniqueness.

In the realm of diamond selection, there is a fifth C that reigns supreme: Choice.

At Powells Jewellery, we understand that each individual possesses their own set of preferences and desires when it comes to their perfect diamond. We celebrate the power of choice, empowering you to curate your own extraordinary diamond experience.

With Choice, you have the freedom to prioritise the aspects of the four Cs that hold the most significance to you. Whether you prioritise a larger carat weight, an impeccable cut for maximum brilliance, a specific colour grade to suit your style, or flawless clarity to capture the purest essence of light, your choices create a symphony of possibilities.

We source our diamonds responsibly, prioritising ethical and sustainable practices, including adherence to the Kimberley Process.
