Are There Any Differences Between Lab Grown Diamonds and Natural Diamonds?

There are a few things different between lab grown diamonds and natural diamonds, but those differences mainly involve availability and affordability.

Lab grown diamonds can be formed in a month or so, and the nature of their formation means that they are not as rare as natural diamonds.

Lab diamonds are also more affordable because they are easier to find and reproduce.

Lab grown diamonds are also potentially more consistent in terms of quality and color, because their formation is more controlled.

Are Lab Grown Diamonds Real Diamonds?

In terms of formation and composition, lab grown diamonds are 100 percent genuine.

Lab grown diamonds are started with a small ‘crystal seed’ – a small shard or flake of crystallized carbon.

From there, carbon is added, and the seed and additional carbon are subjected to the same high heat and pressure as a natural diamond would face during their creation within the earth.

The resultant gem is identical to a naturally formed diamond. It can not be differentiated from a regular diamond by eye, nor even by a professional appraisal.

The only potential composition difference is when lab grown diamonds are deliberately formed in colors that are rare in nature.

– The blush pink and baby blue diamonds featured by Lightbox are two examples of the type of color that is more likely to be possible with lab grown diamonds than naturally formed diamonds.

Are Lab Graded Diamonds Certified the Same Way As Natural Diamonds?

Naturally formed diamonds are certified and graded according to the 4Cs: Color, Clarity, Carat Weight, and Cut.

Lab grown diamonds are graded and certified according to the exact same standards.

The lab grown diamonds produced by Lightbox and sold by Blue Nile are all produced with the following guaranteed quality:

– A Clarity of VS: Very Small Inclusions (also called VSI)

– A Cut Quality of Very Good

Color and Carat Weight are determined by the specific diamond color and design that you select for your jewelry.

Are There Disadvantages to Purchasing Lab Grown Diamonds Rather Than Natural Diamonds?

Lab grown diamonds, like natural diamonds, will last forever and maintain a high sparkle if cared for properly.

Beyond that, there are advantages and disadvantages to choosing lab grown over natural, according to fashion experts.

Potential Advantages or Selling Points:

In terms of aesthetics, there are no disadvantages to choosing a lab grown diamond over a natural one. The sparkle and quality are the same.

In terms of affordability, lab grown diamonds are much easier on the budget.

Lab grown diamonds don’t come with questions about being responsibly sourced, or conflict free, which can avoid potential ethical considerations.

The quality and color of lab grown diamonds can be controlled, meaning you can guarantee higher quality diamonds, even in colors rarely found in nature.

There’s a minimal environmental impact in growing lab diamonds, whereas mining does come with some concerns.

Lab grown diamonds have the potential to be more sustainable for the industry in the long run.

Lab grown diamonds mean that there is a wider market for diamonds in terms of affordability and production.

Potential Disadvantages:

The inherent value of the lab grown diamond is not yet determined, meaning it has little to no resale or insurance value.

A widespread industry of lab grown diamonds leaves the potential for quality control issues.

The exact details of energy usage and process are not well known, for those who have environmental concerns.

Some feel that the lack of rarity inherent in lab grown diamonds decreases the personal and emotional value.

As lab grown diamonds become more mainstream, the overall value of the diamond may decrease, causing backlash among the gemstone community.

Are Lab Grown Diamonds The Same As Simulated Diamonds?

Unlike lab grown diamonds, simulated diamonds are not real diamonds in any sense of the word. They do not have the same composition, nor are they made of carbon.

There are other differences as well, including:

– Simulated diamonds are actually formed of glass or cubic zirconium, starting with the crystal seeds used at the beginning of the process.

– Simulated diamonds don’t have the luster that lab grown diamonds do or the same refraction.

– Simulated diamonds are generally more brittle and fragile than lab grown diamonds, and more likely to fracture when exposed to heat or pressure.

– Simulated diamonds generally cannot be certified or graded, and therefore cannot be as easily quality guaranteed.

Final Thoughts

Blue diamond sells mostly natural grown diamonds, with plenty of options to choose from in that area.

However, if you’re concerned about budget, or have other concerns about naturally sourced stones, then Blue Nile does offer their Lightbox collection of lab grown diamond jewelry for purchase.

Blue Nile lab grown diamonds are sold with a guaranteed high quality, and the options for colors that are almost impossible to find naturally.

You might not be able to get a custom made, designed from the ground up ring from the Lightbox collection, or loose diamonds, but they’re still made with all the quality Blue Nile is known for, and worth looking at if you think a lab grown diamond is a better choice for you.
