What is the most realistic fake diamond?

Diamonds have long been cherished for their beauty and rarity. However, the high cost of natural diamonds has led many to seek alternatives. Enter fake diamonds, which have become increasingly sophisticated and realistic. This article explores the most realistic fake diamonds, providing a thorough understanding of the different types, how they compare to real diamonds, their costs, visual similarities, care and maintenance, and tips for purchasing.


Explanation of Fake Diamonds

Fake diamonds, also known as diamond simulants, are materials that mimic the appearance of real diamonds. They can be natural or synthetic and vary widely in terms of composition, quality, and price. The key distinction between fake diamonds and real diamonds lies in their chemical and physical properties. While real diamonds are composed of pure carbon arranged in a crystalline structure, fake diamonds are made from different substances designed to look like diamonds.


The development of fake diamonds has evolved significantly, with modern technology producing simulants that are almost indistinguishable from real diamonds to the naked eye. These advancements have made diamond simulants a popular choice for those seeking the allure of diamonds without the high price tag.

Types of Fake Diamonds

Cubic Zirconia (CZ): Cubic zirconia is one of the most common and affordable diamond simulants. Made from zirconium dioxide, CZ is colorless, hard, and optically flawless. It closely resembles a diamond but lacks the brilliance and fire due to its lower refractive index and dispersion.

Moissanite: Moissanite is a silicon carbide crystal with a higher refractive index than diamonds, giving it more brilliance and fire. Discovered in a meteorite, natural moissanite is extremely rare, so it is typically produced synthetically. Moissanite is more expensive than CZ but is also more durable and visually striking.

White Sapphire: White sapphire is a natural gemstone composed of aluminum oxide. It is less brilliant than diamonds and can appear slightly milky or cloudy. However, it is a good option for those seeking a natural stone at a lower cost than diamonds.

Glass: While not a high-quality simulant, glass can be cut and polished to resemble diamonds. It is much softer and less durable, making it unsuitable for everyday wear.

Synthetic Diamonds: Also known as lab-grown diamonds, these are real diamonds created through high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) methods. They have the same physical and chemical properties as natural diamonds but are more affordable and ethically produced.

Comparison with Real Diamonds

When comparing fake diamonds to real diamonds, several factors come into play: appearance, durability, and value.

Appearance: To the untrained eye, high-quality fake diamonds like moissanite and synthetic diamonds can look nearly identical to real diamonds. However, experts can distinguish them based on specific characteristics. For example, moissanite’s higher refractive index gives it more fire, which can be a giveaway. Synthetic diamonds, being real diamonds, are virtually indistinguishable from natural ones without specialized equipment.

Durability: Real diamonds are the hardest known natural material, rated 10 on the Mohs scale of hardness. This makes them incredibly resistant to scratching and damage. Moissanite is the second hardest (9.25), followed by white sapphire (9), and cubic zirconia (8). Glass, being much softer, is the least durable.

Value: Real diamonds hold significant value and can be a good investment, while fake diamonds generally do not appreciate over time. Synthetic diamonds, however, can retain some value as they are real diamonds, though typically less than their natural counterparts.

Cost Comparison

The cost of fake diamonds varies widely depending on the type and quality. Here’s a breakdown of average costs:

Cubic Zirconia: CZ is the most affordable, with prices ranging from $10 to $50 per carat.

Moissanite: Moissanite is more expensive than CZ but still significantly cheaper than diamonds, costing around $300 to $600 per carat.

White Sapphire: Prices for white sapphires can range from $50 to $500 per carat, depending on quality.

Glass: Glass simulants are the cheapest, often costing less than $10 per carat.

Synthetic Diamonds: Lab-grown diamonds cost about 20-30% less than natural diamonds, with prices starting around $1,000 per carat.

In comparison, natural diamonds can cost anywhere from $2,000 to over $25,000 per carat, depending on factors like size, cut, color, and clarity.

Visual Similarity

Visual similarity to real diamonds is a crucial factor for many buyers of diamond simulants. Here’s a closer look at how each type stacks up:

Cubic Zirconia: CZ can look very similar to diamonds, especially when new. However, it tends to become cloudy and lose its sparkle over time.

Moissanite: Moissanite’s brilliance and fire often exceed those of real diamonds, making them incredibly striking. However, the difference in sparkle can be noticeable to trained eyes.

White Sapphire: White sapphires lack the diamond’s brilliance and can appear cloudy or milky. They also exhibit different light patterns due to their lower refractive index.

Glass: Glass lacks the sparkle and fire of diamonds and can appear dull and scratched over time.

Synthetic Diamonds: As they are real diamonds, lab-grown diamonds have the same visual properties as natural diamonds, making them the most visually similar simulants.

Care and Maintenance

Caring for fake diamonds requires understanding the specific needs of each type to maintain their appearance and longevity.

Cubic Zirconia: CZ should be cleaned regularly with warm soapy water and a soft brush. Avoid exposure to harsh chemicals and extreme heat, as this can cause clouding.

Moissanite: Moissanite is durable and can be cleaned with a mild soap solution or specialized jewelry cleaner. It resists scratching and can be worn daily.

White Sapphire: White sapphires should be cleaned with warm soapy water and a soft brush. Avoid ultrasonic cleaners and harsh chemicals, which can damage the stone.

Glass: Glass should be cleaned with a gentle soap solution. It is prone to scratching and chipping, so it should be handled with care.

Synthetic Diamonds: Lab-grown diamonds are as durable as natural diamonds and can be cleaned using traditional methods, including ultrasonic cleaners and steamers.

Purchasing Tips

When purchasing fake diamonds, consider the following tips to ensure you get the best quality and value:

Know Your Priorities: Determine what aspects are most important to you—appearance, durability, cost, or ethical considerations. This will guide your choice of simulant.

Research Reputable Sellers: Buy from reputable jewelers who provide detailed information about the stones, including their origin and any treatments applied.

Request Certification: For synthetic diamonds, ask for certification from a recognized gemological lab to confirm their authenticity and quality.

Compare Options: Look at several stones and compare their appearance and prices. High-quality simulants can vary widely in terms of brilliance and fire.

Check Return Policies: Ensure the seller has a good return policy in case the stone doesn’t meet your expectations.

Consider the Setting: The setting can enhance or detract from the appearance of the fake diamond. Choose a setting that complements the stone and enhances its visual appeal.

Understand the Warranty: Some stones, especially synthetic diamonds and moissanite, come with warranties that cover defects and damage. Be sure to understand the terms and conditions.

Try Before You Buy: If possible, see the stone in person before purchasing. This allows you to assess its visual qualities under different lighting conditions.

Be Aware of Treatments: Some simulants are treated to enhance their appearance. Understand what treatments, if any, have been applied and how they might affect the stone’s long-term appearance and durability.

Budget Wisely: Set a budget that aligns with your priorities and stick to it. While it’s tempting to go for the highest quality, remember that all fake diamonds offer significant cost savings compared to natural diamonds.


In conclusion, the search for the most realistic fake diamond involves considering several factors, including the type of simulant, its visual similarity to real diamonds, cost, durability, and maintenance needs.
