A diamond buyer could find themselves staring at two stones with very similar colour, clarity, cut quality and carat weight but see a vast difference in price between the two. One could have come from underground over a huge amount of time, but the other could have been produced in a laboratory-controlled environment.
That difference in origin is the root of a lot of the confusion surrounding the topic of lab grown diamond vs real diamond. The phrasing can be misleading as a laboratory-grown diamond is still a real diamond. Instead, there is a comparison between a lab diamond and a diamond mined naturally from the earth.
Knowing what does and does not change can make picking out an engagement ring or other fine jewels a whole lot simpler.
Lab-Grown Diamonds Are Diamonds, Not Imitations
Lab-grown diamonds have pretty much the same crystal structure and core physical properties as natural diamonds. They are made of crystallised carbon and can be cut and polished using the same processes as mined diamonds.
They also should not be confused with diamond simulants such as cubic zirconia and moissanite that share visual characteristics but have other chemical and optical differences.
Laboratory-grown diamonds are generally formed using either the Chemical Vapor Deposition method or the High Pressure High Temperature method. These techniques simulate the conditions that enable diamond crystal growth rather than extracting a diamond directly from the earth.
For buyers making a comparison between lab grown diamond vs real diamond, origin is therefore a telling point rather than if one is genuinely a diamond or not.
Can You See a Difference Without Equipment?
Typically, the origin of a diamond can not be told just from looking at a good quality cut stone.
A lab-grown round brilliant diamond and a natural round brilliant diamond that share very similar grades can be visually indistinguishable from one another. Diamond performance is dictated to a large extent by the cut quality and techniques rather than origin.
This is why it is so key to assess what you are getting during an engagement ring shopping trip: higher carat weights with poor cut proportions can look duller compared to smaller stones with sharper angles.
Buyers should look at:
- Cut quality and shape
- Colour grade
- Clarity grade
- Carat weight
- Shape and measurements
- Any certification or grading
Natural and laboratory-grown diamonds can both have various internal characteristics. Their origins are different and trained gemologists can spot them easily with professional equipment.
Where the Trade-Off Becomes Clear
The differences become clearer if a few key buying points are juxtaposed.
- Factor Lab-Grown Diamond Natural Diamond
- Composition Crystallised carbon Crystallised carbon
- Origin Lab-created Formed naturally underground
- Appearance Can visually match natural diamonds Traditional natural diamond appearance
- Grading Can receive independent grading reports Can receive independent grading reports
- Price relationship Often costs less at comparable prices Usually commands a higher price
- Rarity Production can increase Limited by natural supply
- Resale considerations Secondary-market values may be less predictable Established resale market, though retail value is rarely recovered fully
The price difference can impact ring design decisions considerably.
A buyer within a fixed budget can utilise the difference in price to focus on improving carat weight, cut specifications or an elaborated setting when choosing a lab-grown diamond. Someone who values the rarity or geological formation of a natural diamond might prefer a mined diamond despite potentially adjusting size or clarity.
Neither approach is right for everyone.
Certification Deserves More Attention Than the Word “Real”
As opposed to asking if a diamond is real, asking what details are known about the stone is more important.
A grading report can show details like carat weight, colour, clarity, measurements and other identifying information. Reports for laboratory-grown diamonds should also clearly state their origin.
Certification is useful to buyers purchasing jewellery online in Singapore, as they may be comparing several stones without a physical inspection of each.
A grading report does not negate the need to visually assess a diamond. Two stones that share a similar grading report can look visibly different due to proportions, placement of inclusions or cut quality.
Buyers conducting research on lab grown diamonds can utilise the grading information along with diamond measurements and ring-choice preferences rather than assessing a stone based on carat weight on its own.
Price Can Change Which Specifications You Prioritise
One way to look at things incorrectly is utilising the available budget to get the highest carat figure possible.
Visible size is partly dictated by shape and measurements. Two 1-carat diamonds can have different face-up dimensions. An elongated oval, pear or marquise may also appear to spread differently from a round stone of the same weight.
If the choice to utilise a laboratory-grown diamond enables a shift or difference in the budget, consider directing some of that shift to specifications that directly impact the ring more.
You might prioritise:
- Better cutting proportions
- A safer setting
- Platinum instead of another metal
- Unique ring proportions
- A matching wedding band
- Higher quality work in pavé or hidden-halo detail
Carat weight may attract some attention, but there is more to a ring than the centre stone.
Natural Origin Still Matters to Some Buyers
The strongest reason for a natural diamond is not visual superiority. It is natural rarity and origin.
Some buyers appreciate the fact that their stone formed naturally in the earth. This can also be a point of interest for some buyers on a collectible or emotional level.
Lab-grown diamonds serve a purpose as buyers can reach the specifications or appearance of a larger natural stone. This makes the argument of lab grown diamond vs real diamond a choice of what you want your money to get.
If natural rarity matters, natural origin may be a better decision. If visible size, specification flexibility or design budget matter more, a laboratory-grown stone may be a better brief.
Think About the Ring, Not the Diamond
The centre stone is only a part of what will be worn for years.
A high-set solitaire can expose the diamond more than a lower setting. Fine pavé can add more sparkle but it will typically require more maintenance than a plain metal band. A bezel setting provides edge protection, while prongs expose more of the diamond.
When choosing an engagement ring, buyers should look at how a setting would look with a future wedding band. Some decorative baskets, halos or low-set styles can create a gap between the two. For everyday wear, ask a jeweller regarding prong security, setting height, cleaning, resizing limitations and maintenance.
What to Verify Before Ordering in Singapore
Before ordering, know exactly what diamond and finished ring you are buying.
Ask about the grading report, stone measurements, metal type, setting style, ring size, production time, resizing terms, warranty, and delivery terms. If the ring is being customised, ask for specifics for the centre stone and setting rather than relying only on photographs.
Also utilise diamond measurements and grading information rather than carat weight when comparing diamonds. A carefully chosen piece with appropriate proportions and a practical setting can serve for everyday wear better than a larger diamond chosen due to its headline specification.
The most beneficial decision is made using the factors of origin, specifications, design, budget and long-term wear together.
