Consumers have a couple options now for diamond jewelry, either natural diamonds or diamonds grown in a laboratory. Both are real diamonds. They both have the same optical, physical, and chemical properties. The only difference is where and how they are grown. This article will give you information to help make an informed decision on purchasing natural versus lab grown diamonds.
Diamonds are popular for many reasons beyond their durability and brilliance. They are a symbol of eternal love, trust, and faith. They can promote creativity and imagination. Additionally, they symbolize wealth and the ability to manifest abundance.
Most natural diamonds are 1-3 billion years old and found in the upper mantle. They are brought to the earth’s crust via ancient volcanic eruptions. Natural diamonds are made by earth’s forces of high pressure and high temperature on the element of carbon. Lab grown diamonds (also referred to as lab created, man-made, or synthetic) are made using one of two different methods in a laboratory. High temperature/high pressure flux growth method uses a molten metal alloy with a diamond seed crystal to initiate growth. The metal alloy is often iron-nickel or iron-cobalt. The second method is called Chemical Vapor Deposition (CVD) where high temperature and low pressure is produced in a vacuum chamber. The resulting crystal structure is the same as a natural diamond thereby making a hard and durable diamond in both cases.
Lab grown diamonds are more environmentally sustainable than natural diamonds. Some of the differences are as follows:
• Natural diamonds require large earth moving equipment that run on fossil fuels to find the gems, whereas lab growns use electricity and sophisticated equipment for several days to form the diamond.
• Natural diamonds support jobs for millions of people across the globe and the money supports families, local economies, and invest in public healthcare, education, roads, electricity, sanitation, and public goods (https://members.americangemsociety.org/page/naturalvslaboratorygrown, found on June 9, 2021). The humanitarian outreach for lab grown is much smaller.
• When dealing with smaller lab grown diamonds, where it was formed is harder to detect, creating an element of deception. But does it matter in the end? It does to the value, since diamond to diamond, lab growns are less expensive.
• Distinguishing between natural and lab grown diamonds requires being able to microscopically and atomically see distinctive features that a really experienced gemologist understands. If a gemologist isn’t dedicated to education or have the right equipment for the determination, the diamond can be sent to a credible lab such as GIA or AGS laboratories. Gemologists need to see or detect the evidence of ancient, prolonged growth in natural diamonds versus recent, rapid lab growth.
• There isn’t a difference to the naked eye, and all diamonds, natural or lab grown, still need grading to determine the carat, cut, clarity, and color (4-C’s) before assigning a value to them. In most cases laser inscriptions on the girdle (waistband) of the diamond will identify lab grown as such.
• Financially, you can get a 30% larger lab grown diamond over a like (4 C’s) natural diamond, dollar for dollar.
While there is something almost romantic about having the earth create your diamond over a billion years ago, lab grown diamonds can be a great alternative for many reasons. In the end, customers should buy what will make them happy. In conclusion, whether natural or man-made, a diamond is durable and tough-a descriptive value for marriages that should have the same values. Either way, we have and can get in lab grown diamonds if that is your choice. Olufson Designs will support your decision and do our best to exceed your expectations.
