Knowledge is life | a lack thereof causes suffering
Yes. Grown diamonds are real and are not fake diamonds. Man-made diamonds are 100% carbon and have the exact same chemical properties as mined diamonds. Lab created diamonds are grown by recreating the conditions underneath the Earth that result in diamond growth: pressure, heat, & carbon. Learn more about why lab diamonds are not fake Grown diamonds are not the same thing as diamond simulants such as cubic zirconia or a CZ with a diamond like carbon (DLC) coating.
No. Diamonds are made entirely from carbon, whereas cubic zirconia contains zero carbon! CZs are much weaker than diamonds and have different light performance and patterning. Any jeweler can easily tell the difference between a diamond and an inferior diamond simulant such as CZ.
No. Grown diamonds and natural diamonds of the same quality look the same, even to a trained eye. Traditional jewelers' tools such as microscopes or loupes cannot detect the difference between a laboratory-grown diamond and a natural, mined diamond. It is impossible. Only a certifiably lab can detect growth line differences and even then its hard! The gemological equipment needed to reliably determine if a diamond is mined or grown is quite complicated and costs over R150 000.00 at best. The most accurate detection method, Photoluminescence Spectroscopy, requires deep freezing the diamonds to −320°F (−196°C)! I've never met a jeweler who own one due to the high cost and complexity
By recreating the conditions underneath the Earth that result in diamond growth: pressure, heat, & carbon. Today, there are two methods of growing diamond gemstones: High Pressure-High Temperature (HPHT) & Chemical Vapor Deposition (CVD). Each process is best suited for certain sizes & colors of diamonds.
It takes 14 days to grow a 1 carat diamond. If you try to grow a diamond any faster, the diamond crystal will fracture. Thus, there is a physical speed limit to how fast you can grow diamonds. The slower the better!
No. Because diamonds are grown by recreating the conditions of nature, lab grown diamonds have the same variations of color and clarity that exist in natural diamonds (the 4Cs). Lab diamonds still range across the color and clarity spectrum, just like mined diamonds. Just like mined diamonds, lab diamonds can vary in their quality even within the 4Cs, so it’s imperative that you purchase your grown diamond from a reliable source
Yes. Grown diamonds tend to retail at a 40-50% discount off of equivalent quality natural diamonds. Grown diamonds are priced based on their quality, just like mined diamonds.
Yes. All lab diamonds above 0.50ct are graded and certified by reputable non-profit gemological laboratories such as AGS, DIA, GIA, IGI, NGIC or GCAL. Up until recently most of the diamonds sold had been graded by IGI; however, we have begun having of our diamonds certified by the DIA, which is our local leading authority lab in South Africa in dealing with certification, so that you as the client can have direct access and peace of mind in regard to quality assurance. We always recommend purchasing a lab diamond that has an independent certification.
Yes. Grown diamonds are easily appraised and insured, just like mined diamonds. All our fine jewelry comes with a full appraisal. Progressive jewelry appraisers, will gladly appraise grown diamond jewelry.
Yes. Just like mined diamonds, there is a resale market for grown diamonds, and this market is ever increasing. A purchaser of a lab created diamond can expect to resell their lab diamond at a similar discount to what they would receive for a mined diamond. It is important to note that both grown & mined diamonds do not increase in value over time, relative to inflation, and should not be considered a place to "park" your money. We advise our clients to view their grown diamond purchase as a luxury, discretionary purchase, not an investment. You should never expect to be able to sell your diamond for more or the same of what you originally paid for it at retail, whether natural or lab grown, relative to inflation. This is because retailers who buy your diamond from you have to be able to resell that stone for a profit
No. Laboratory-grown diamonds do not fade, discolor or cloud over time.
Yes, it is sustainable to grow diamonds with abundantly available carbon and renewable energy. Growing diamonds is certainly energy intensive; however, the impact on the earth to grow diamonds is a fraction of the impact of diamond mining. It requires approximately 250 kilowatt hours of electricity to grow a 1 carat diamond. That same amount of electricity could power the average household for 14 days.
Cut, Color, Clarity, & Carat Weight Lab diamonds receive grading reports from independent gemological organizations on the 4Cs: Cut, Color, Clarity, and Carat Weight. Just like in mined diamonds, lab diamonds will exhibit variations across the 4Cs and range from poor to superlative quality. Not all lab diamonds are perfect, colorless, and flawless! Cut The cut of the diamond is a measure of the quality of the shape, geometry, and finish of diamond gemstone. Only round brilliant diamonds receive formal cut grades on a scale from Ideal (the best) to Poor. Color A perfect diamond, with no impurities and no defects, is completely colorless. Impurities such as nitrogen cause undesirable yellow or brown tones in the diamond. Color is graded on a range of letters from D to Z Clarity Clarity is a measurement of how many blemishes or inclusions are present in the diamond, which can be either defects in the diamond crystal or microscopic foreign particles within the diamond. The lower the clarity of a diamond, the more imperfections in the diamond. Clarity is graded on a range from Internally Flawless to Included. Carat The carat weight of a diamond is a measurement of its weight. One carat is exactly one-fifth of a gram (0.20 g). When a diamond is properly cut, the carat weight defines the size of the diamond, and larger diamonds tend to be more expensive. When it comes to smaller diamonds, an Ada Concierge may use the term “points” to discuss diamond weights with you. One point is one-hundredth of a carat (0.01). A “33 point diamond” would be one-third of a carat (0.33 carats).
Its all about the fifth C! CONSCIENCE: THE FIFTH 'C' The two main reasons our clients choose a lab diamond are origin and value. Rest assured that your diamond did not result in the funding of conflict in a war-torn country, nor did it require leaving a mile-wide hole in the ground. Mining diamonds from the earth is energy intensive and ecologically invasive process. Some open-pit diamond mines are more than 3 miles wide. For the prototypical 1 carat diamond, over 5 tonnes of earth must be blasted and extracted by heavy diesel equipment. Every year, millions of tons of greenhouse gasses are emitted to mine diamonds in fragile ecosystems around the world including the Canadian and Siberian arctic tundra, the desert of Western Australia, and rivers of Africa. growth processes are more energy efficient and sustainable. Many of our suppliers are already using renewable energy for their diamond production. Virtually no water is used to grow diamonds, and it only takes about a gram of raw carbon (graphite) to produce every carat of diamond that we sell. All by-products and chemicals used during the diamond growth and jewelry manufacturing processes are either recycled or properly disposed of via chemical processing companies. Then there is the budget and quality factor!
Just like with mined diamonds, lab diamonds can vary significant in quality. That's why it is so vital to purchase certified gems!
