How to Distinguish Lab-Grown, Mined, or Fake Diamonds

When buying diamond jewellery, is the most apparent question to be asked irrelevant? If you want to buy an eternal piece of diamond jewellery, Alex Bros Jewellers in Oakleigh, Victoria, is your provider. Our Greek family have been serving the jewellery industry since 1951, and our entire diamond stock embodies these values in quality and standards.

The first thing you should know before you purchase a diamond (or before you sell it) is the kind of grade of diamond you wish to sell or buy. This post will help you determine the best way to determine if your diamond is real or fake, or if it is mined or artificial, before you lay your hand on this type of jewellery as an investor, ensuring you have all the knowledge you need.

Identifying Lab-Grown, Mined, or Counterfeit Diamonds

With a well-trained eye capable of recognizing the distinct characteristics of mined diamonds, lab-grown diamonds, and counterfeit stones, an expert can differentiate between each type with precision. With the proper testing, one can determine where your diamonds come from. Looking out for the footprints will help you identify your diamonds.

Identifying Lab-Grown, Mined, or Counterfeit Diamonds

Different Types of Diamonds: Mined vs. Lab-Grown

Diamonds are basically of two kinds: one is natural, and the other is cultivated in the laboratory. Both diamonds are distinguishable in terms of their qualities. The primary differences between them are given below:

  1. Diamonds are found in nature and cultivated by human beings. Mined diamonds are collected from mines, whereas lab-grown diamonds are developed in the laboratory with high-end chemicals and machines.
  2. Natural diamonds take years to form; conversely, lab-grown diamonds develop within a month.
  3. Diamonds are available in different shapes and sizes. Mined diamonds are more significant, whereas lab-grown diamonds are smaller in size.
  4. Diamonds can be used for different purposes. In both cases, they are used for jewellery, but neatly cut diamonds are used for space protection.
Different Types of Diamonds: Mined vs. Lab-Grown

Mined Diamonds

  • Natural Formation: Mined diamonds are part of the geological formation that happens approximately 80 miles (130 kilometres) below the surface due to extreme temperature and pressure conditions via natural occurrence.
  • Supply is finite: Mined diamonds are a finite resource. The supply of mined diamonds is determined by geological factors, such as where the diamond deposits are and under what mining regulations.
  • Sources: Mined diamonds are available in numerous countries, including Africa, Australia, Russia, Canada, etc.
  • Natural imperfections: Mined diamonds contain natural imperfections called inclusions — tiny crystals that form during the crystallisation process.
  • Traditional Certification: Mined diamonds may be approved by a gemological laboratory, such as the International Gemological Institute (IGI), to prove their origins and quality.

Lab-Grown Diamonds

  • Artificial Synthesis: Lab-created diamonds are grown in a lab using technology that perfectly mimics the conditions of natural diamond growth.
  • Environmentally Friendly: Lab-grown diamonds can be considered more environmentally friendly than mined diamonds because their relatively low CO2 footprint does not require mining or cause environmental degradation.
  • Ethically Responsible: Lab-grown diamonds are more ethically regulated because they do not require the mining of natural diamonds, which is often associated with poor and unethical working conditions in other countries.
  • Uniform quality and clarity: very few natural imperfections, meaning the clarity is more uniform.
  • Monopoly-free: Lab-grown diamonds can be created very quickly, which means that more will be available annually.
  • Certification and Grading: Every lab-grown diamond is certified and graded by the same laboratories used for mined diamonds, the institutes that potential buyers rely upon for ensuring the creation of a genuine, natural diamond. You can find more about diamonds here.

A Guide to Differentiating Lab-Grown, Mined, or Fake Diamonds

Armed with nothing more than this simple rule—look at every diamond, just as you would any other gemstone, through the prism of appearance, composition, and certification—most of us can differentiate between a mined diamond and a lab-grown and artificial synthetic (i.e., fake) with a reasonable degree of confidence. The author uses technical and specialist terms proficiently in an accessible, informative manner.

Steps to Determine if Your Diamonds are Lab-Grown, Mined, or Fake

Discerning whether it is mined from culture, cultured from, or simulated is an entirely adventurous and cautious painstaking process. It’s a path through a scientific wonderland – professionally precise – if arduous. How does it work?

  • Visual Inspection: The first is visual: lab-grown diamonds are feats of human engineering and nearly always appear seamless. The colour and clarity are consistent, without the fanciful inclusions that often characterise mined diamonds, which are the sculpts of natural circumstances. Mined diamonds can have a rainbow of colours and irregularities within them, alluding to their earthly origin.
  • Specialised Equipment: If so, digging deeper will require instruments. Gently magnifying a crystal within a gem will give your eyes new, enlarged vision, like applying a jeweller’s loupe or a microscope. Natural growth rings like those of a tree can reveal a stone’s lab origins; inclusions hold tales of how a grower shaped it; even fluorescence can whisper the secret of the elements that a diamond was suspended in as it grew. Alex Bros Jewellers has different equipment to test diamonds and check their authenticity.
  • Grading Reports: Authenticity is also certified via grading reports detailing the diamond’s biography, weight, shape, and cut characteristics. Certificates attest to the diamond’s identity and are issued by well-trusted laboratories, the arbiters of gemological truth. Missing a report entirely or having a dissonant one is typically enough to alert someone of forged goods.
  • Inscriptions: It’s down there, in tiny writings, waiting to be revealed. These are the cryptic signatures of gems, their tiniest ink tattoo, engraved by laser beams inscribed with secret code that speaks of origins. Lab-grown diamonds can typically be inscribed in a particular way, marking them as unique and traceable in the gems’ registry.
  • Professional Advice: If in doubt, seek the opinion of an experienced jeweller. The experts who craft their customers’ finest pieces have sophisticated techniques—spectroscopy and thermal conductivity testing, among many others—at their disposal. With their confirmation, buyers can be assured that their diamonds are precisely what they seem to be.
  • Market Dynamics: Knowing the market is essential. Synthetics have disrupted the diamond industry and the demand for mined diamonds, forcing changes and innovation to ensure a more sustainable, ethical alternative and a product that appeals to a new demographic looking for sustainability and responsible social connections.
  • Ethical Considerations: The ethical dimensions are significant, too. Mined diamonds are slathered in centuries’ worth of environmental devastation and human suffering, frequently tainted with blood, both figuratively and literally. Cultured diamonds offer a lucid story that chimes with the concerns of the modern, informed consumer.
  • Technological Advances: It is extraordinary to create so-called lab-grown or ‘cultured’ diamonds (HPHT or CVD diamonds). These recreate the processes of mineral formation using high-pressure, high-temperature (HPHT), or chemical vapour deposition (CVD) methods, resulting in indistinguishable diamonds from mined diamonds in every physical characteristic.
  • Investment Perspective: From an investment perspective, mined and lab-grown diamonds may still be in the eye of the beholder. Because of the historical perception of the value of mined diamonds, one would expect them to maintain their worth. However, given that lab-grown diamonds are gaining wider acceptance, we may see a shift in how consumers view them and their long-term investment value.

How to Tell the Difference Between Lab-Grown, Mined, or Counterfeit Diamonds

You need a catch-all visual inspection to ensure you are looking at a grown diamond, dug diamond, or fool’s gold. Then, send it to an expert jeweller to analyse the 4Cs — cut, clarity, colour, and carat — plus additional laboratory equipment for definitive results. And voilà! You’re the last portal in the integrity chain that brought the geological requirement from its fathom-deep provenance to your collection.
