What are

Lab Grown Diamonds

Lab-grown diamonds share the same chemical structure as natural, mined diamonds. While mined diamonds are formed in the earth over millions of years through combined heat and pressure, lab diamonds are produced in a lab in a much shorter period, in a simulation of that same environment.

Lab diamonds are graded for the same criteria as mined diamonds, and have the same durability. To the average viewer, mined diamonds and lab diamonds look the same; only a trained gemologist using special equipment can discern the difference.

Diamond Grading Explained

Carat

People often believe that carat refers to the size of a diamond, but it actually refers to the weight. The higher the carat, the more costly the diamond, as diamonds are priced according to their weight and quality.

Colour

A chemically pure diamond consisting of pure carbon would be completely colourless. Colour in diamonds comes from trace elements in the stone (most often nitrogen, which give diamonds a yellowish hue).

Colourless diamonds are graded from D to Z. D, E, and F graded diamonds are considered "colourless", and G, H, I, and J coloured diamonds are considered "near colourless". From there, diamonds start to take on a noticeably yellowish tone (or sometimes brown, or a mix of both). Colour is viewed as the most subjective of the gradings, because sometimes you may prefer the look of a warm coloured stone, or something champagne. When looking for a traditional colourless diamond, we generally would be considering I colour or higher.

Our lab grown diamonds will always be D, E, or F colour, giving them a stunning colourless appearance. We may select down to a G colour for 1.50ct marquise diamonds, as they are rarer lab grown diamonds and can be tricky to source.

Lab grown diamonds are generally very hard or not possible to source in lower colour grades/champagne tones.

Clarity

During their formation, diamonds can form internal characteristics that are called "inclusions," and external characteristics known as "blemishes." The highest quality diamonds have no visible inclusions and no blemishes at all.

Clarity is divided into 6 categories:

  • Flawless (FL): No inclusions and no blemishes visible under 10x magnification
  • Internally Flawless (IF): No inclusions visible under 10x magnification
  • Very, Very Slightly Included (VVS1 and VVS2): Inclusions so slight they are difficult for a skilled grader to see under 10x magnification
  • Very Slightly Included (VS1 and VS2): Inclusions are observed with effort under 10x magnification, but can be characterized as minor
  • Slightly Included (SI1 and SI2): Inclusions are noticeable under 10x magnification
  • Included (I1I2, and I3) Inclusions are obvious under 10x magnification which may affect transparency and brilliance. Inclusions are often dark or black, and usually easily visible to the naked eye.

For the most part, anything over an SI1 grading is considered "eye clean," meaning any inclusions are not visible to the naked eye.

Our lab grown diamonds will be VVS1 - VS1 clarity, meaning they will be perfectly clean to the naked eye, with only very minor inclusions that can only be seen under magnification.

Cut

Cut is a diamond characteristic that is often neglected, but is actually the most important factor in a beautiful stone. This is because the Cut determines how the diamond will sparkle and come to life.

For round brilliant diamonds, cut is usually graded on three aspects:

  • Make: the overall quality of the cut (angles and proportions, etc.)
  • Polish: the quality of the surface finish of the diamond
  • Symmetry: the design and proportions of the diamond

Fancy shapes (ie. emerald cut, oval, marquise, pear, cushion, etc) are traditionally only graded for polish and symmetry and do not have Cut (make) gradings.

The grading for these aspects depends on the laboratory assessing the stone: GIA and GCAL use Excellent > Very Good > Good > Fair > Poor, while IGI uses Ideal > Excellent > Very Good > Good > Fair.

Round brilliant cut diamonds have scientifically designed proportions and facets, to the point that there is a possible "perfect" cut against which all round brilliant diamonds are compared. It's important to keep in mind though that in real life, diamonds will be worn in a variety of lighting situations, which will change the way the diamond sparkles and looks. "Perfect" proportions are always great to aim for, but those designed proportions are also generally measured in specific lab lighting.

For fancy shapes, the polish and symmetry are usually the most important factors, with length to width ratios also being an important factor. We generally try to select stones within 'ideal' ratios for each shape. However, it's important to note that shape is very subjective and can be used creatively for achieving different designs.

Antique cuts also usually fall outside the norms of lab grading, usually receiving Fair or Poor cut grades, despite being visually stunning. They don't fit into modern measurements for Cut grades.

Our round lab grown diamonds will have excellent or ideal cut/polish/symmetry. Other shapes will have excellent to very good cut/polish/symmetry.

Fluorescence

Fluorescence in diamonds refers to how reactive the diamond is to UV light. In slightly yellow-hued diamonds (ie. a K colour), strong blue fluorescence can make them appear whiter than they actually are. About 25-35% of natural diamonds have some degree of fluorescence. It usually does not have any impact on the appearance of the diamond, but if a black light were to shine on it, it may have a faint glow.

Grading Laboratories

Though it is the most well-known, the GIA (Gemological Institute of America) is not the only laboratory that grades diamonds.

For a long time, the GIA didn't grade lab grown diamonds at all (this has changed in recent years as lab grown diamonds have become more common and accepted in the jewellery industry). Because of this, many lab grown diamonds are graded by other institutions:

  • IGI (International Gemological Institute)
  • GCAL (Gem Certification & Assurance Lab)

The centre stones in our lab grown diamond rings will always be accompanied by a report, but depending on availability at the time of purchase, they may be certified by any one of these three labs. Your ring will come with a diamond grading certificate prepared by either the GIA, IGI, or GCAL.

Round - Six Prongs

Beautifully balanced, your round brilliant diamond will have two subtle groups of three prongs on either side of the band.

Oval - Four Prongs

An oval shaped diamond held in four prongs strikes a perfect balance between delicacy and security. The prongs at the four corners create a slight visual "squaring" effect, making the stone appear more rectangular.

Oval - Six Prongs

Like our six prong option for round diamonds, but elongated; your oval diamond will be cradled between three prongs at either end.

Emerald - Four Prongs

Forever a classic, your emerald cut lab grown diamond will be held with a single finely-pointed claw at each corner.

Emerald - Eight Prongs

An LF favourite, with two claw-shaped prongs at each corner of your lab grown emerald cut diamond, uniquely accentuating the stone's shape.

Pear - Five Prongs

With a cluster of three prongs at the pear's pointed tip and two prongs at the pear's rounded base, our five prong option keeps your pear shaped diamond secure. One prong is required on the point of the pear to protect it.

1ct Grey Pear Ilona Ring - OOAK

Pear - Six Prongs

Our six prong option for pear cut diamonds has three prongs at the diamond's pointed tip, and three prongs at the diamond's rounded base. One prong is required on the point of the pear to protect it.

Marquise - Six Prongs

Our marquise diamonds are set with six prongs; three at either end. Prongs are required on the points of the marquise to protect them from breakage. Six is the required minimum amount of prongs.

Cushion - Four Prongs

Cushion cut diamonds are set with four prongs, one at each corner, delicately supported and secured.

Lab Grown Diamond FAQ

What's the difference between natural and lab grown diamonds?

Lab grown diamonds (also known as lab created diamonds, man made diamonds, and lab diamonds) are chemically and physically the same as natural, mined diamonds. Natural diamonds form in the earth over millions of years, while lab grown diamonds are created in a fraction of that time in a lab. Regardless of origin, they are formed in the same way: as carbon atoms that are put under immense heat and pressure until crystals are formed.

Because lab grown diamonds and natural diamonds are physically the same, they are graded with the same criteria (cut, colour, clarity, and carat) on the same scales. They have the same brilliance and durability as natural diamonds, and to the average viewer they are impossible to tell apart visually. Even trained gemologists require advanced technology to tell the difference between natural and lab grown diamonds.

Lab Grown diamonds will always be laser inscribed to indicate that they have been lab grown (only visible under 30x magnification).

Where are your lab grown diamond rings made?

Like all of our jewellery, our lab grown diamond rings are made entirely by hand in Toronto, Canada by our small team of in-house goldsmiths.

Each ring is modified in wax by hand to suit your unique centre stone before being cast in gold. The ring is then polished and the diamonds are set, before receiving its finishing touches and being carefully inspected for quality.

How long will it take to make my lab grown diamond ring?

Our lab grown diamond rings have the same production timeline as the rest of our engagement rings, which can fluctuate throughout the year but is generally 4-8 weeks.

If there is a particular date you need to receive your ring by, please make a note of it at checkout.

Can you make me a ring using a lab grown diamond in a shape or size not listed?

Maybe! Lab grown diamonds are not available in all diamond cuts, so depending on what you are looking for, we may or may not be able to source it for you.

If you want a ring with a diamond option that isn't listed, such as a carat weight between the provided options or a different cut, please submit your request using our bespoke form here.

I have my own lab grown diamond; can you put it in a ring for me?

At this time, we are not able to work with customer supplied stones, metal, or pieces to be disassembled/re-made into something new, including lab grown diamonds.

We also do not sell our rings without the centre stone.

Do you work with fancy coloured lab grown diamonds or other lab grown stones?

At this time, we only work with colourless lab grown diamonds. We do not work with fancy coloured or enhanced lab grown diamonds or other lab grown gemstones (such as sapphires, rubies, emeralds, alexandrites, moissanites, etc).

Can you help me if I need my lab grown diamond ring adjusted after I've received it?

If any sizing or additional adjustments must be made to the design after it's received, we will help you ship the piece back to us (please contact us for shipping details before shipping the piece back). The shipping, sizing and adjustment costs will be the responsibility of the customer.
