In the world of jewellery, the phrase fake diamonds called pops up frequently as buyers seek alternatives that match the sparkle of genuine diamonds without the premium price. This guide dives into what those “fake diamonds called” really are, how they’re produced, how they differ from real diamonds, and what to look for when shopping. By the end, you’ll understand the landscape of simulants and lab-grown options, so you can make an informed choice that suits your budget, ethics and style.
Understanding the realm of fake diamonds called: what does the term cover?
The expression fake diamonds called refers to a wide range of stones and materials that mimic the appearance of natural diamonds but are not traditional, untreated natural diamonds. In practice, the category includes:
- Simulants: stones that look like diamonds but have different chemical compositions. Common examples are cubic zirconia and white sapphire.
- Moissanite: a popular lab-created gem that closely resembles diamonds in both fire and brilliance, though it is not a diamond.
- Lab-grown (or lab-created) diamonds: real diamonds formed in laboratories rather than in nature, with identical chemical and physical properties to mined diamonds, but still often grouped under the umbrella of fake by some sellers or buyers depending on context.
- Other diamond simulants and alternative gemstones that appeal for their sparkle or durability but do not claim to be natural diamonds.
The reason the phrase fake diamonds called can be confusing is that it covers both genuine diamonds created in laboratories and stones that are merely imitations. In conversations about value and authenticity, differentiating between simulants and lab-grown stones is essential because their price, durability and societal perception can be very different.
Common types of fake diamonds called and how they differ
Cubic Zirconia: the classic fake diamonds called
Cubic Zirconia (CZ) is among the most well-known fake diamonds called. It is a synthetic gemstone crafted from zirconium dioxide and is celebrated for its dazzling clarity and affordability. CZ can be produced in a near-colourless range and frequently features in cheaper jewellery across the high street. Although it can be cut to mirror facets of a diamond, CZ lacks the natural refractive index and dispersion that give diamonds their distinctive fire. For many buyers, CZ offers excellent value for occasional wear or fashion jewellery, but its hardness and scratch resistance are lower than those of diamond, meaning it may show wear more quickly with daily, long-term use.
Moissanite: the glittering alternative
Moissanite is a popular fake diamonds called option that has gained traction because of its higher refractive index, yielding more sparkle than most CZs. Originally discovered in meteorite material, moissanite is now predominantly lab-made and available in near-colourless to warmer tones. In terms of hardness, moissanite sits well above CZ and approaches the hardness of diamond, making it more durable for everyday wear. The trade-off is that moissanite’s sparkle can appear more colourful with a rainbow-like fire, which some observers interpret as different from classic diamond scintillation. For many buyers, moissanite represents a compelling compromise between price and beauty, earning strong position among fake diamonds called options.
White sapphire and other mineral simulants
White sapphire is another widely available fake diamonds called option. It’s a natural gemstone that can be enhanced or resurfaced to achieve a clean, near-colourless appearance. While white sapphire is considerably harder than other simulants, it still lacks the hardness of diamond. It tends to be more affordable than moissanite and can offer a durable, chic look for those who prioritise value and understated radiance over maximum sparkle.
Lab-grown diamonds: are they real or fake?
Lab-grown diamonds, also called cultivated or cultured diamonds, are chemically and physically identical to mined diamonds. The primary distinction lies in their origin: lab-grown diamonds are manufactured in controlled environments using high-pressure high-temperature (HPHT) or chemical vapour deposition (CVD) processes. Some retailers categorize lab-grown diamonds as real diamonds, while others classify them as fake diamonds called when differentiating them from natural stones. For shoppers prioritising ethics, consistency, or price, lab-grown diamonds offer a compelling option without compromising the intrinsic properties of a true diamond, such as hardness (Mohs 10) and brilliance.
How fake diamonds called are produced: from lab to showroom
Simulants: crafting sparkle without the diamond chemistry
Simulants like cubic zirconia are manufactured through precise chemical processes that produce a stone with similar optical properties to diamond. The aim is to replicate the brilliance and clarity, rather than the exact chemical makeup. CZ is manufactured in large quantities, which makes it affordable. The manufacturing process also allows for consistent cuts and shapes, making it easy for jewelers to set in a range of jewellery designs. The result is a visually convincing option that can be startlingly similar to real diamonds at first glance, especially in the showroom environment.
Moissanite: engineered brilliance and resilience
Moissanite’s journey begins with silicon carbide, grown in a lab, then cut and faceted to diamond-like proportions. The result is a gem with superior fire and a brightness that often outshines many diamonds of comparable size. Because moissanite is engineered, its properties are predictable across batches, which helps jewelers offer consistent quality. The production workflow prioritises crystal quality, uniform dispersion, and long-term durability, making moissanite a popular choice for engagement rings and everyday wear.
White sapphire and other minerals: natural materials, synthetic finishes
White sapphire can be produced using natural material with enhancements, or entirely synthetic white sapphire grown in controlled environments. The outcome is a gem with better hardness and durability than many simulants, but typically less “diamond-like” fire. Some jewellery wearers appreciate the subtler sparkle of white sapphire as a more understated alternative to the high brilliance of diamond or moissanite. The production line is designed for reliability and value rather than extreme optical performance.
What to look for when evaluating fake diamonds called against real diamonds
Hardness and durability: Mohs scale considerations
Diamonds rate a 10 on the Mohs scale, making them incomparably hard among natural gemstones. The fake diamonds called options vary significantly. Moissanite sits around 9.25, cubic zirconia around 8–8.5, and white sapphire roughly 9. The higher the number, the more resistant the stone will be to scratches in daily wear. If you want a long-lasting piece you’ll enjoy for years, prioritise a harder material and ensure a robust setting.
Brilliance, dispersion and fire
One of the most striking differences between fake diamonds called and real diamonds is the way light is dispersed. Diamonds exhibit a unique balance of brightness, fire and scintillation. Moissanite can appear more fiery and colourful, sometimes giving a rainbow effect, whereas cubic zirconia may look crystal-clear but can lack the subtle nuances seen in true diamond facets. This distinction is subtle and highly personal, so carful inspection or a trusted jeweller’s opinion can help you decide which look you prefer.
Colour and clarity
Genuine diamonds come in a range of colours and clarity grades. For the generic consumer, the most common stones chosen in everyday jewellery are near-colourless grades (G–I) or similar, where the visual impact is often minimal to the untrained eye. Fake diamonds called options tend to have fewer natural inclusions than high-quality natural diamonds, but some simulants can display their own distinctive inclusions or translucency. When assessing a piece, look for uniform colour and a consistent appearance, especially in larger stones.
Cuts and proportions: how the stone is finished
A well-cut gem reflects light with precision. In the world of fake diamonds called, the quality of the cut is equally important as the material itself. A good cut maximises brilliance while minimising dark areas. Retailers often emphasise the cut grade as a key selling point, particularly for moissanite and high-quality CZ, where superior cutting can elevate the overall impression of the piece.
How to tell fake diamonds called from real diamonds: practical tests
Professional appraisal and certification
The most reliable way to distinguish between fake diamonds called and real diamonds is to obtain an independent appraisal or certification. Reputable laboratories provide detailed reports on the stone’s identity, origin, and properties. A certificate can confirm whether the stone is a natural diamond, a lab-grown diamond, or a simulant. For any significant purchase, particularly engagement rings or heirlooms, professional validation is worth the cost and peace of mind.
Diamond testers and thermal conductivity
Diamond testers are common tools used by jewelers and consumers alike. They measure thermal conductivity to determine whether a stone is a diamond. While efficient for quick checks, testers may not reliably differentiate between diamond and moissanite, as both can conduct heat at similar rates. For a definitive result, pairing a tester with a visual assessment or an X-ray analysis is advisable.
Refractive index and fire tests
Advanced gemologists may use refractive index measurements to distinguish between stones. Diamonds have a distinct refractive index that affects how light travels through the gem. Simulants tend to display different optical behaviours. A professional appraiser or gemologist can perform precise measurements using specialised equipment to identify the stone with high confidence.
Setting, weight and price cues
Another practical approach is to consider the overall package: cost, the mounting, and the size relative to normal expectations for real diamonds. If a deal seems too good to be true, it probably is. Be wary of vastly cheaper stones set in elaborate jewellery, especially if the seller cannot provide credible certification or a transparent origin story.
Ethics, sustainability and the truth about fake diamonds called
Environmental impact of diamond supply chains
Questions about ethics and sustainability have increasingly shaped consumer decisions. The mining of natural diamonds can entail environmental disruption and labor concerns, which has driven interest in alternatives. Fake diamonds called options, especially lab-grown diamonds and moissanite, are often pitched as more responsible choices, albeit with varying carbon footprints depending on production methods and energy sources. Buyers should consider the full lifecycle of the stone, including mining, processing, transport, and end-of-life recycling when possible.
Economic implications for communities and markets
When people purchase fake diamonds called alternatives, they sometimes influence price signals in markets for natural diamonds. Some argue that a robust market for simulants and lab-grown stones reduces demand for mined stones, while others believe it has little ripple effect on natural diamond values. The reality depends on market trends, consumer preference, and the availability of transparent supply chains. For many, choosing fake diamonds called options aligns with personal values around ethics and economic pragmatism.
Choosing the right option: fake diamonds called versus genuine diamonds
Budget and lifestyle considerations
Budget-conscious buyers may prioritise a beautiful piece without paying premium prices. In this context, fake diamonds called such as CZ or moissanite offers substantial immediate sparkle with a much lower financial commitment. Those who wear jewellery daily may prefer the durability and long-term wear of moissanite, which can be a closer match to diamond in terms of resilience while still remaining affordable.
Occasion and sentiment
The decision often comes down to occasion and personal sentiment. An affordable, high-sparkle CZ ring may be ideal for a temporary engagement or a fashionable piece, while a real diamond is often chosen for long-term symbolism and transfer of worth. Lab-grown diamonds can offer a middle ground, delivering the real diamond identity with a more sustainable backstory and typically lower price than mined stones.
Quality and care expectations
Consider how you want to care for your piece. Simulants such as CZ may require gentler handling to avoid scratching, while moissanite is more durable but still benefits from proper cleaning and care. Lab-grown or natural diamonds can tolerate daily wear well, with proper maintenance and occasional professional inspection. The care routine you adopt should reflect the stone type and setting, regardless of whether the label reads fake diamonds called or something closer to a natural diamond.
Care and maintenance: keeping fake diamonds called looking their best
Cleaning routines for different materials
Regular cleaning helps maintain brilliance. For CZ and moissanite, a gentle warm water bath with mild soap and a soft brush is typically sufficient. Avoid harsh chemicals that might damage coatings or metal settings. For white sapphire and other mineral-based stones, follow manufacturer guidelines and consult a jeweller if you’re unsure. When cleaning any gemstone, use a soft brush and avoid aggressive cleaning methods that could loosen settings or scratch the surface.
Storage and protection
Proper storage protects against scratches and chipping. Use soft pouches or lined jewellery boxes, ideally keeping stones separated to prevent contact with harder materials. Regular checks of settings help ensure stones remain secure, particularly for pieces worn daily or carried in pockets and bags where impact could dislodge a stone.
Insurance and appraisal considerations
If you own a piece with a fake diamonds called component—whether CZ, moissanite, white sapphire, or a lab-grown diamond—it’s wise to insure appropriately. Many insurers base coverage on the replacement value, which should reflect the stone type and setting. Obtain documentation and, if possible, a certificate that clarifies the stone’s identity for future proofing and resale considerations.
Resale value: what to expect from fake diamonds called
Compared with natural diamonds, fake diamonds called—particularly simulants—generally depreciate more quickly, reflecting their lower intrinsic value. Moissanite and lab-grown diamonds may retain a higher resale value when they come with credible documentation and quality branding, but their market performance still varies. If resale value is important, seek stones with solid provenance, a respected certification, and a reputable retailer or jeweller who can facilitate a fair appraisal and trade-in options.
Frequently asked questions about fake diamonds called
Are fake diamonds called truly indistinguishable from real diamonds?
No. While high-quality simulants and lab-grown stones can closely resemble natural diamonds, trained gemologists and sophisticated testing can differentiate them. If you’re unsure, a professional appraisal is the most reliable route to clarity.
Is moissanite a fake diamonds called?
Moissanite is commonly referred to as a fake diamonds called due to its similarity to diamonds in appearance. However, it is a distinct mineral (silicon carbide) with different optical properties and stress patterns. It remains a popular choice for those seeking high sparkle at a lower price point.
Which is more durable: cubic zirconia or moissanite?
Moissanite generally offers greater durability than cubic zirconia due to its higher hardness and resistance to scratching. For everyday wear, moissanite tends to hold up better over time, making it a preferred option for engagement rings and daily jewellery.
