Fake diamonds, or diamond look-alikes, are called diamond simulants, imitation diamonds, or diamond accents, and common examples include Cubic Zirconia (CZ), Moissanite, and white sapphire, which mimic diamonds' appearance but have different chemical and physical properties, unlike synthetic (lab-grown) diamonds that are real diamond but made in a lab.
Simulated diamonds are also known as diamond simulants and include things like cubic zirconia (CZ), moissanite, and YAG.
A lab diamond, also known as a cultured diamond, a synthetic diamond, or a man-made diamond, is a diamond that is created in a laboratory setting using advanced technology. Lab diamonds are made using one of two methods: High-Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD).
cubic zirconia. Cubic zirconia is a type of simulated diamond that is not a natural stone but a man-made replica. It's the cheapest alternative to a diamond but does not compare in quality to the real thing. A cubic zirconia stone costs $30 or less on average and is often used in costume jewelry.
Fugazi was popularized by its use (referring to a fake diamond) in the 1997 mobster film Donnie Brasco and the 1988 book it was based on, Donnie Brasco: My Undercover Life in the Mafia.
The Aquamarine name comes from the Latin word for seawater and is said to calm waves and keep sailors safe at sea. It is sometimes referred to as a poor man's diamond because of the pale color.
Moissanite is harder, more durable, and offers greater brilliance, making it suitable for long-term wear. Cubic zirconia, while less durable, provides a more subdued sparkle and is an economical choice for short-term use or decorative jewelry.
I Clarity diamonds are the diamonds in the Imperfect clarity category. As you can see from this simulation, I1, I2 and I3 diamonds sit at the low end of the grading scale. The GIA states that I clarity diamonds possess: 'Inclusions that are obvious under 10× magnification and may affect transparency and brilliance'.
Ans. The best fake diamonds are cubic zirconia (CZ), moissanite, and lab-grown diamonds. CZ is affordable and looks similar to real diamonds. Moissanite offers great brilliance and durability.
Cubic Zirconia (CZ) Vs.
Cubic zirconia is probably the most commonly known diamond alternative. CZ is often found in children's and costume jewelry, but it is sometimes used in placeholder and lower quality engagement rings. It is an artificially produced version of the element zircon.
A diamond simulant, diamond imitation or imitation diamond is an object or material with gemological characteristics similar to those of a diamond. Simulants are distinct from synthetic diamonds, which are actual diamonds exhibiting the same material properties as natural diamonds.
Currently, all types of moissanite are created in labs, significantly affecting their pricing. As opposed to diamonds, moissanite does not require the expensive and energy-demanding processes of mining and accessing the resource, hence leading to much lower prices for customers.
Cubic zirconia (CZ) is a man-made stone, developed in the 1970s as a cost-effective diamond simulant. It is composed of zirconium dioxide and is created in a controlled lab environment. Cubic zirconia is known for its ability to mimic the look of a diamond while being available at a much lower cost.
Simulants are also called imitations, faux, and fakes. While a garnet simulating a ruby may be a real garnet, it's a fake ruby. Some vendors may be honest about selling simulants. Others may not disclose what the gem truly is.
7 Popular Diamond Alternatives
A “Lab Diamond,” also known as a “Synthetic Diamond,” or “Man-Made Diamond” is a diamond gemstone that was made in a laboratory instead of the Earth's crust.
Fake diamonds are variously called diamond simulants, diamond imitations or diamond accents. Some simulants occur naturally, while others are created artificially. Examples of popular created diamond simulants include cubic zirconia, moissanite, rhinestone and crystal.
A diamond simulant mimics the look of a diamond but lacks a diamond's molecular structure. For instance, glass or cubic zirconia (CZ) can be cut to resemble diamonds, but they are not durable enough for engagement rings.
Moissanite. If you want a quality synthetic diamond ring, chances are you'll run into jewelers who sell Moissanite. This can be a natural mineral, but nearly all of it is made in a lab. Chemically, Moissanite is made up of crystalline silicon carbide.
Taylor Swift's engagement ring features a large, antique Old Mine Brilliant Cut diamond, which is a vintage style with rounded corners, a high crown, and large facets, giving it a soft, candlelit sparkle rather than sharp modern flashes, often described as an elongated cushion shape with a small, open culet. This historical cut, popular in the 18th and 19th centuries, was chosen for its romantic, nostalgic character, perfectly suiting the ring's yellow gold setting with hand-engraved details.
Top 10 Diamond Cuts
For a $5,000 budget, you can typically get a natural diamond engagement ring with a center stone around 0.75 to 1.0 carat, possibly slightly larger (up to 1.2 ct) in elongated shapes like pear or oval, depending on cut, color, clarity, and the setting's cost, with lab-grown options allowing for much larger (3-4+ carat) stones or alternatives like moissanite offering bigger stones within budget.
The Cons: It's just not a traditional diamond
If you're set on tradition, or you want a stone that holds resale value, moissanite might not be your first choice. While it's beautiful and durable, it doesn't carry the same prestige as diamonds, and some jewelers or jewelry lovers may not see it as a true equal.
Zirconia is considered the best diamond imitation in the market. Zirconia can withstand very high temperatures (2750°C) and can therefore be set like a diamond. Zirconia can be applied to jewelry without the need for adhesives, making it extremely durable and ideal for everyday wear.
Most moissanite stones will pass a traditional diamond tester due to their high thermal conductivity. However, slight variations in quality or size may affect the accuracy of the test. Advanced testing methods are necessary for reliable results across all moissanite samples.
