Lab Grown Diamonds
What are lab grown diamonds?
Lab-grown diamonds also referred to as lab-created diamonds, man-made diamonds, manufactured diamonds, or engineered diamonds, consist of carbon, just like natural diamonds. The dissimilarity between a lab-grown diamond and a natural diamond lies not in their appearance but in their growth process. Natural diamonds form deep within the earth over millions or even billions of years. In contrast, lab-grown diamonds are cultivated within a controlled machine environment and take anywhere from a few days to several months to develop, depending on their size.
Generally, it proves challenging for a trained gemologist or jeweler to distinguish between a lab-grown diamond and a natural diamond based solely on visual examination.
Lab Grown Diamonds FAQs
How Are Lab Grown Diamonds Made?
Currently, there are two ways lab-grown diamonds are created – the HPHT (high-pressure high temperature) and CVD (chemical vapor deposition) methods.
- The HPHT process closely mimics the conditions that diamonds need to form naturally, but they do it much quicker.
- CVD diamonds grow from an HPHT-grown diamond seed crystal. Carbon rains down from a plasma cloud and deposits onto the seed crystal, growing diamond in layers.
Both processes produce the same gem-quality lab diamonds. However, the CVD process is becoming more common in the industry because it’s more cost-effective and the machinery is a lot smaller.
At Gittelson Jewelers, our wholesalers list both HPHT and CVD diamonds.
How Are Lab-Grown Diamonds Graded?
Are Lab-Grown Diamonds Flawless?
No, lab-grown diamonds can have inclusions just like natural diamonds, just composed of different materials. They are graded on the same clarity scale as natural diamonds. Grades ranging from Flawless to SI2 are available. There are a myriad of different lab-grown diamond options out there for you to choose from.
What Does it Mean if my Lab-Grown Diamond is Treated?
Sometimes CVD-grown lab-grown diamonds come out of the machine with a brownish tint so they are treated for color post-growth. This is a stable process and will not affect the diamond in any way over time. It can still be put in an ultrasonic machine to be professionally cleaned and take heat from a jeweler’s torch. This is just an added step in the growing process for some diamonds in order to attain a higher color grade with less of a brownish tint. Our lab-grown diamond article has a detailed section about post-growth treatment for more information.
What is the Difference Between lab-Grown Diamonds and Moissanite?
A lab-grown diamond is a real diamond, just created in a machine rather than the earth. It has the same chemical, physical and optical properties and is composed of carbon. Moissanite is a diamond simulant. This means it looks like a diamond, but that’s where the similarities end. Moissanite has a completely different chemical makeup. One quick way to tell the difference between a diamond (lab or natural) and moissanite is to check for doubling in the facets. Diamond is singly refractive and will only show 1 set of facet junctions when looking at the diamond through the bezel facets while moissanite is doubly refractive and will show 2 sets of facet junctions. (Magnification and training is required for this.)
Are Lab-Grown Diamonds a Good Investment?
Lab-grown diamonds are a great alternative to natural diamonds, especially if you are looking for a larger stone within your budget since they usually have a lower price point. Resale value can vary over time just like any other natural or lab-created gemstone. Since lab grown diamonds are a newer product on the market, there is more uncertainty on future pricing when compared to natural diamonds.

Popular Ring Styles
In the end, we ended up choosing a simpler and less expensive ring than I was originally considering. This was their suggestion since they thought the proportions would look better with the diamond I chose as well as the size of my fiancée's hand. I could not ask for a better shopping experience. The selection is top of the line for elegance and design. Never will you find a horrendous item. We will definitely be returning for wedding bands when the time comes for it.
As a nice touch and demonstration of their connection to the industry, Molly, Mike and Gene provided us with recommendations for vendors as we are starting to plan the wedding. This service is not to be missed! Go to Gittelson Jewelers - you will not regret it!
It's also a nice perk they are open M-F downtown in the skyway so we can stop by anytime and get the rings cleaned.
