Imagine two exquisite tiaras, one adorned with dazzling diamonds that twinkle like stars in the night sky and the other adorned with breathtaking sapphires that shimmer with an ethereal blue hue. If you were granted the chance to possess only one, which would you choose?

While some may have a resolute answer, others may find themselves caught in a captivating dilemma. If you find yourself torn between these magnificent treasures, allow me to present a concise comparative analysis, adding a touch of intrigue and excitement to your decision-making process.

What Are The Main Differences Between Sapphire & Diamond?


Diamond, a singular gem, consists solely of carbon, whereas sapphire represents a distinct variety of corundum, an aluminum oxide crystalline form.

Brilliance & Fire

When it comes to brilliance, which refers to the undispersed white light emitted by a gemstone, diamonds surpass sapphires with a refractive index of 2.42, while sapphires range between 1.76 and 1.77. As a result, diamonds exhibit greater brilliance and fire, showcasing a dazzling array of colorful flashes when illuminated by white light, compared to sapphires.

Origin & History

Diamond deposits, believed to be the oldest, emerged approximately 900 million years ago, deep within the Earth's mantle. Historical records indicate that diamonds were initially discovered in India and traded as early as the 4th century B.C. 

Since their unearthing, these precious gemstones have been highly sought after by royalty and the affluent. The ancient Greeks even attributed their formation to the tears of gods. Today, diamonds continue to captivate with their unrivaled brilliance, symbolizing love, fearlessness, and abundance.

Birthstone & Zodiac Sign

Diamonds, the official birthstone for April and the gemstone for the Aries zodiac sign hold a special place in the world of gifting. They are also the traditional choice for celebrating the 60th and 75th wedding anniversaries.

Sapphires, on the other hand, are esteemed as the official birthstone for September and the zodiac stone for the Virgo star sign. They make for a meaningful gift to mark the 5th and 45th wedding anniversaries, symbolizing enduring love and commitment.


Sapphires often contain imperfections, including liquids, gases, and even crystals of other minerals. Inclusions are commonly found in diamonds, with the rarest and highest quality grade being F.L. (flawless).

Gemological Phenomenon

Sapphires possess pleochroism, which means they can showcase varying colors depending on the viewing angle. Additionally, certain sapphires exhibit asterism, resembling a star-like effect, and chatoyancy, resembling the appearance of a cat's eye.

In the case of some diamonds, such as chameleon diamonds, exposure to U.V. lamps can cause a remarkable color change.


The cost of a high-quality sapphire can vary greatly, ranging from $50 to $10,000 per carat. Similarly, the price of a 1-carat diamond can start at $2,500 and climb as high as $30,000, depending on its quality.


The round cut is highly coveted for its ability to maximize the brilliance and fire of diamonds, making it the most sought-after shape. However, modern diamond cuts such as oval, emerald-cut, pear, cushion, and marquise are also popular choices.

Sapphires, on the other hand, offer a variety of shapes to choose from, including round, cushion, oval, emerald-cut, and pear.


Diamonds, known as the hardest mineral to date, achieve a perfect 10/10 rating on the Mohs scale of hardness. In contrast, sapphires receive a different rating.

Good To Know:

When considering affordability, diamonds tend to be more expensive. However, if you prefer a colorless/white diamond without breaking the bank, consider opting for Very Slightly Included (VS) diamonds with a grade of VS1 or VS2. It is advisable not to go below this grade.

In terms of size, sapphires are denser and heavier than diamonds. Consequently, even if they have the same weight, sapphires will appear smaller than a one-carat diamond. 

The price of sapphires also increases significantly once they reach the 5-carat mark. To enjoy the remarkable beauty of this gemstone, it is recommended to choose a sapphire ranging from 1 to 2 carats.
