American Diamonds vs Natural Diamonds: Understanding the Difference

Shopping for diamond jewellery can feel confusing once you hear the term "American Diamond." Many buyers assume it refers to diamonds mined in America. 

In reality, it means something entirely different. If you have ever compared American diamonds vs natural diamonds and wondered which is right for you, this guide breaks down exactly what sets them apart.

What Are American Diamonds?

American diamonds are not diamonds at all. Instead, they are cubic zirconia, a lab-created stone designed to mimic a diamond's brilliance. Because cubic zirconia is manufactured rather than mined, it costs a fraction of the price. The name "American Diamond" is largely a marketing term used across South Asia, and it has no real connection to American-mined stones.

This synthetic stone offers impressive sparkle for the price. However, its shine tends to fade slightly with everyday wear. Jewellers often use American diamonds in fashion jewellery, statement pieces, and occasion wear, where affordability matters more than permanence.

What Are Natural Diamonds?

Natural diamonds form deep within the earth over billions of years, under intense heat and pressure. Carbon atoms crystallize slowly, creating a stone with genuine rarity and enduring hardness. Each natural diamond carries unique inclusions, almost like a fingerprint, because no two stones form in exactly the same way.

Because natural diamonds take so long to form and are difficult to mine, they command a significantly higher price. Their durability, brilliance, and rarity make them a popular choice for engagement rings and heirloom jewellery. Unlike cubic zirconia, a natural diamond's sparkle does not diminish over time.

American Diamonds vs Natural Diamonds: Key Differences

When comparing American diamonds vs natural diamonds, several factors stand out clearly.

• Composition: American diamonds are cubic zirconia, a synthetic compound. Natural diamonds, on the other hand, are pure crystallized carbon formed underground.
• Price: American diamonds cost significantly less, making them accessible for everyday and occasion wear. Natural diamonds, in contrast, carry a premium price reflecting their rarity.
• Durability: Natural diamonds rank as the hardest known natural material, scoring a perfect 10 on the Mohs scale. American diamonds, meanwhile, sit around 8 to 8.5, so they scratch and dull more easily over time. 
• Sparkle: Both stones sparkle brightly when new. However, natural diamonds refract light with more depth and fire, while American diamonds tend to produce a flatter, more uniform shine.
• Value retention: Natural diamonds hold long-term value and can even appreciate. American diamonds, by comparison, hold little resale value since they are mass-produced.

Which One Should You Choose?

Choosing between American diamonds and natural diamonds depends largely on your purpose and budget.

If you want a statement piece for a single event, an American diamond makes practical sense. You get maximum visual impact without a heavy investment. For example, a bold cocktail ring or a pair of chandelier earrings works beautifully in cubic zirconia.

If you are searching for a piece meant to last generations, like an engagement ring or a wedding gift, a natural diamond is worth the investment. Its durability and lasting brilliance justify the higher cost, especially for daily wear.

Therefore, think about how often you will wear the piece. Also consider whether it needs to withstand years of use. These two questions guide the decision more than price alone, especially when weighing American diamonds vs natural diamonds for a lifetime piece.

How to Tell Them Apart?

Distinguishing American diamonds from natural diamonds is not always easy with the naked eye. That said, a few simple tests can help:

• The fog test: Breathe on the stone. A natural diamond disperses heat instantly and clears within a second or two, while cubic zirconia stays fogged for several seconds longer.
• Weight: Cubic zirconia weighs more than a natural diamond of the same size, since it is denser.
• Sparkle colour: Natural diamonds reflect a mix of white and coloured light. American diamonds often throw more rainbow-coloured flashes, appearing slightly "disco-like" under bright light.
• Certification: A natural diamond typically comes with a grading certificate from a recognised gemological lab. Cubic zirconia never does, since it holds no comparable market value.

How To Care for Each Stone?

Both stones need gentle handling, although natural diamonds tolerate daily wear far better.

Clean American diamond jewellery with a soft, dry cloth to avoid clouding. Store each piece separately to prevent scratches from other jewellery. Avoid exposing it to harsh chemicals, since the coating on some settings can wear off over time.

Natural diamonds, meanwhile, can be cleaned with mild soap and warm water. Because of their hardness, they resist everyday scratches well. Still, regular professional cleaning keeps their brilliance at its best.

Final Thoughts

Both American diamonds and natural diamonds have a place in modern jewellery collections. American diamonds offer affordable glamour for fashion-forward pieces. Natural diamonds offer permanence, rarity, and lasting value for life's biggest milestones.

Frequently Asked Questions

Is an American diamond a real diamond? 

No. It is cubic zirconia, a lab-made stone designed to resemble a diamond.

Do American diamonds turn yellow over time? 

They can lose their shine and appear duller with prolonged wear, though quality plating slows this process.

Are natural diamonds a good investment? 

Yes, especially larger, well-graded stones, since they tend to hold or grow in value over time.

Can jewellers tell the difference instantly? 

Experienced jewellers can usually spot the difference using simple tests or specialised tools, even without lab equipment.
