Brief History of Both Diamonds and Moissanite

Diamonds, formed deep within the Earth’s mantle, have been treasured for centuries as symbols of wealth, power, and love.

Their sparkle and hardness make them the perfect choice for engagement rings and other jewelry pieces. On the other hand, moissanite is a gemstone first discovered in a meteor crater in 1893.

It’s a rare mineral, and most of the moissanite used in jewelry today is lab-created.

Why the Comparison is Relevant Today

With growing concerns over the ethical implications of diamond mining and the environmental impact it carries, many consumers are looking for alternatives.

Moissanite, being almost as hard as diamonds and exhibiting a similar sparkle, has emerged as a popular choice. Moreover, its lab-grown nature ensures it’s a more sustainable option.

Faceoff: Diamonds vs. Moissanite


When it comes to cost, moissanite generally offers more bang for the buck. Diamonds are priced based on the four Cs – carat, clarity, color, and cut.

Their rarity, especially in higher grades, drives up their price. Moissanite, being lab-created, doesn’t have the same scarcity factor, making it a more affordable option.

Market Trends Influencing Price

The diamond industry has seen fluctuations in pricing due to geopolitical issues, market demands, and shifts in consumer preferences.

Lab-grown diamonds and alternatives like moissanite challenge the traditional diamond market, influencing pricing structures.

Future Price Predictions

As lab-growing techniques improve and become more widespread, the price of moissanite may further decrease.

Conversely, as the demand for ethically sourced diamonds grows, we might see a rise in their prices due to increased production costs.


Both diamonds and moissanite are hard substances, with diamonds being the hardest known mineral. This durability ensures that both stones can withstand daily wear, making them ideal for jewelry that’s worn regularly, like engagement rings.

How to Test and Compare Durability

There are several tests jewelers use to determine a gemstone’s durability. The scratch test, where a gemstone is used to scratch another surface, is one common method.

However, it’s essential to note that while diamonds can scratch other substances, they can also be chipped if hit with enough force.

Factors Affecting Durability

Environmental factors, daily wear and tear, and even the setting of the jewelry can influence a stone’s durability.

For instance, prong settings might leave the gemstone more exposed to potential damage than bezel settings.

Sparkle & Fire

The sparkle of a gemstone is often its most captivating feature. While diamonds are known for their brilliant sparkle, moissanite is renowned for its fiery rainbow flashes.

Scientific Explanation of Sparkle and Fire

The sparkle in gemstones, also known as brilliance, is the result of light reflecting off its internal and external surfaces.

Fire refers to the dispersion of light into the colors of the rainbow. Moissanite tends to have higher dispersion than diamonds, resulting in more fire.

Practical Implications for Jewelry

The choice between diamonds and moissanite can depend on individual preferences regarding sparkle and fire.

Some might prefer the classic brilliance of diamonds, while others might be drawn to the colorful fire of moissanite.

Overall Appearance Broken Down By Shape


Round is the most popular shape for both diamonds and moissanite, prized for its classic look and maximum brilliance.

The facets in round cut stones are designed to reflect the most light, making them the sparkliest of all cuts.


Oval cuts are elongated, offering a larger surface area, making the stone appear bigger than round stones of the same carat weight. This shape has gained popularity in recent years for its modern yet timeless appeal.


Cushion cuts combine the best of round and oval shapes, with rounded corners and larger facets. These increase the stone’s brilliance and highlight its clarity.



Clarity refers to the internal and external imperfections, known as inclusions and blemishes. While diamonds can have various inclusions affecting their clarity grade, moissanite is typically more consistent in clarity due to its lab-grown nature.

How Clarity is Graded for Both Stones

Diamond clarity is graded on a scale from Included to Flawless, based on the visibility and number of inclusions. Moissanite, being lab-created, typically falls on the higher end of the clarity scale.


Diamonds come in a range of colors, from colorless to yellow or brown, with colorless being the most valuable.

Moissanite, on the other hand, can exhibit a yellow or greenish hue under certain lights, especially in larger stones.

Color Grading Scales

Diamond color is graded on a scale from D (colorless) to Z (light yellow or brown). Moissanite color grades are generally categorized as Colorless, Near Colorless, and Faint Color.
