Lab Grown Diamond VS Moissanite: What Are The Differences? | with LeCaine Gems

July 26, 2022

Lab Grown Diamonds and Moissanite, what are the difference?

Lab-made diamonds and Moissanite are two of the most popular alternatives to the natural diamond. While they no doubt each possess compelling traits that make them the ideal stone, there are a few factors that set them apart. This article compares these two diamond substitutes by sharing with you their key characteristics.

What are Moissanite and Lab Grown Diamonds?

Lab grown diamonds are essentially real diamonds that are developed in the laboratory, created through technology that is capable of replicating the formulation process of natural diamonds. Due to this controlled high temperatures and high pressure process, lab made diamonds are composed of the same chemical properties as the natural diamond: made from 100% carbon. On the other hand, Moissanite is a natural mineral that was first discovered by Henry Moissan in 1893. As natural moissanite is incredibly rare, lab-created moissanite is used in jewellery instead. Moissanite is composed of 50% carbon and 50% silicate. 

Defining Characteristics of Moissanite and Lab Grown Diamonds: 

1. Conflict-free, Ethically Sourced & Sustainable

As both gemstones are created in a lab environment, they exert a substantially lower impact on the environment as compared to the natural diamonds, which are derived through the means of mining. 

2. Stone Cut and Shape

Lab created gemstones allow for a greater versatility when it comes to the cuts and shapes as compared to natural diamonds which are constrained by its intrinsic shape. As such, these two diamond alternatives certainly provide a greater flexibility in terms of stone cut and shape, to accommodate your jewellery preferences. Likewise, you may obtain them in the classic round brilliant cut, or in fancy cuts.

3. Colour and Clarity

Both Moissanite and Lab Grown Diamond abide by a colour grading scheme that is similar to that of the Natural Diamond.

Generally, the ‘D’ ‘E’ ‘F’ grades, being closer to white diamonds, command higher prices. As you go down the alphabetical order towards ‘G’ or ‘J’, the colour of the diamond is seen to be slightly more yellow. 

As the two gemstones are created in a lab setting, the colour of the gemstones can be controlled. This explains why coloured moissanite and lab-grown diamonds are increasingly popular options to natural gemstones.

At LeCaine Gems, we deliver the quality you deserve by using the best stone cuts, colour and clarity for our gemstones. Adhering to the highest standards, our Moissanite and Lab Grown Diamonds are available in the best colour and clarity grades, ‘D’ and ‘VVS’ respectively. Based on individual preference, customers may also obtain them in ‘E’ and ‘F’ grades.

 4. Hardness and Durability 

As Lab Grown diamonds are made 100% the same in terms of its physical composition, it bears the same hardness index as the natural diamond, scoring 10/10 on the Mohs hardness scale. On the other hand, Moissanite ranks as the second hardest gemstone after the diamond, with a slightly lower hardness index of 9.25/10. 

With that said, both moissanite and the lab-made diamond are incredibly durable, capable of withstanding the test of time. It is extremely rare that breakages or scratches will occur for both gemstones. 

5. Sparkle and Brilliance

Due to a difference in their refractive index, the moissanite and lab-grown diamond exhibit a different sparkle. The Moissanite has a refractive index of 2.65, which enables it to emit a rainbow-like glow which is accentuated when viewed under the light. This allows it to radiate a sparkle and glow that is even more brilliant than the natural and lab-made diamonds.

At the same time, the lustre and brilliance of both moissanite and lab-made diamond remains intense and persists throughout the years without traces of dulling or cloudiness. Similar to the natural diamond, they do not lose their shine and sparkle over time.Lab Grown Diamond and Moissanite

How Lab Grown Diamond and Moissanite are created at LeCaine Gems:  

As compared to the traditional way of obtaining the natural diamond, which takes years to be formed and cultivated deep in the earth’s core, the process of creating moissanite and lab-grown diamonds under lab conditions generates a lower degree of carbon footprint and requires a lesser period of time. 

Lab Grown Diamonds: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD) are two ways to create a lab-grown diamond, with both methods yielding the same results over the span of a few weeks.These processes ensure that the lab-grown diamond is made a hundred percent the same in terms of its physical properties to that of the natural diamond. 

Moissanite: Through the use of technology, a block is created exactly like a stone. It is a highly electrolyte process, where the moissanite is formed with the components of carbon and carbon silicate. Once the polishing process is complete, the gemstone cutting sets in to attain the different facets and cuts. 

Price comparison of Lab Grown Diamond and Moissanite: 

Moissanite is a more affordable option as compared to Lab Grown Diamonds. Currently, the market price of the lab-grown diamond is estimated to be about 40-50% of the price of the natural diamond. While the moissanite costs a fraction of that at a significantly lower price, estimated to be about 10% of the natural diamond price. 

While both of these diamond substitutes have been available for decades, the technology to create moissanite has been around a longer time, therefore accounting for its lower price. On the other hand, while the lab-grown diamond has seen an increase in popularity and demand in the last few years, the process of creating the lab-grown diamond is known to be costlier. Furthermore, given that lab-grown diamonds are perceived as identical to the diamond, this association likely spurs a marketing exception that draws a close link to the value of the natural diamond. As such, the lab-grown diamond has a price range that is closer to the diamond as compared to moissanite. 

Given their similar physical traits, the amount of financial savings is a determining factor when choosing between the two. With moissanite, one can obtain a larger carat size stone at a significantly lower price as compared to the lab-grown and natural diamond.

Some commonly asked questions regarding Moissanite and Lab-grown Diamonds answered: 

1. Can you tell Moissanite and Lab Grown Diamonds from Natural Diamonds?

Moissanite and lab grown diamonds bear an identical appearance to the natural diamond, making it difficult to differentiate between them for the layman.

Depending on personal preference, a few key characteristics may make one more favourable than the other. 

Choose Moissanite If: 

- You want to maximise financial savings

- As Moissanite are priced more affordably than lab-grown diamonds, one will be able to acquire a larger carat size at a lower price as compared to the natural or the lab-grown diamond. This translates to the ability to opt for more elaborate designs composed of more gemstone details when one chooses the Moissanite.
