Man Made Diamonds
&
Created Diamond Rings



Man made diamonds are perfect for couples looking for affordable, 100% conflict free and environmentally friendly diamond wedding rings or engagement rings.

Here you will find how lab diamonds measure up to real diamonds, different types of lab created diamonds, and pros and cons which may help you to decide which diamond might be right for you (*if you want to see how man made diamonds compare to real diamonds scroll down to the table below).

Affordable Engagement Rings With Top Quality Man Made Diamonds


There are two types of diamonds which are man made: synthetic diamonds and diamond simulants.

Simulant diamonds look similar to real diamonds, but they are chemically and physically different from diamonds. The top diamond simulants include Nexus diamonds, moissanite and cubic zirconia.

Synthetic diamonds, also known as cultured or created diamonds, HPHT diamonds, and CVD diamonds, are 'grown' in a laboratory and they have physical and chemical characteristics which are practically identical to real diamonds. (Laboratories which produce these diamonds microscopically inscribe them with a number so they cannot be identified as 'real' diamonds for insurance or reselling purposes).

Check out Lab Created Diamonds to learn more about synthetic diamonds and created diamond rings.

  • HPHT (high pressure high temperature) synthetic diamonds mimic conditions in a laboratory which are needed to form real diamonds in nature; CVD (carbon vapor deposition) creates conditions which cause hydrocarbon gas to crystallize and form diamonds.
  • Synthetic lab diamonds are new to the market, and became widely available in the last five years. Simulant diamonds have been available since the 1970's in the form of cubic zirconia, and in the past decade in the form of moissanite and Nexus simulants.

Eco-Friendly Lab-Grown Diamonds


Comparing Synthetic Diamonds to Real Diamonds:
  • From the table, you can see that synthetic lab diamonds are extremely similar to real diamonds. The only difference: most synthetic diamonds are less expensive than real diamonds, and they are nearly flawless whereas most diamonds have some inclusions and blemishes.
  • The only major con towards synthetic diamonds is the price; you can save thousands of dollars with the purchase of fancy color synthetic diamonds, but they are still priced much higher than simulant diamonds.

Comparing Simulant Diamonds to Real Diamonds:

  • Simulant diamonds are not as hard as a real diamond, their brilliance and fire is not exactly like a real diamond, and unlike most real diamonds they are flawless.
  • The biggest pro towards simulant diamonds is their cost. A one carat colorless loose cubic zirconia is around $40.00, a one carat colorless loose Nexus diamond is around $100.00, and a loose one carat moissanite diamond is around $320.00.
  • The biggest con towards a simulant diamond is their difference in brilliance and fire. The Nexus simulant comes close to looking like a real diamond, a moissanite diamond has the highest brilliance and fire which can create a 'disco ball' effect that is undesirable to some consumers, and the cubic zirconia has a lower brilliance, but higher fire, than real diamonds.
  • Another con: While Nexus and moissanite diamonds are so hard they cannot be scratched under most circumstances, the cubic zirconia diamond can scratch with long term wear and it has a tendency to absorb oils. As a result, a cubic zirconia diamond may appear cloudy if scratches accumulate on the surface and if it is not regularly cleaned.
  • The moissanite diamond, like most real diamonds, is not colorless. These diamonds have a very light tint of yellow or brown which may or may not be visible to the naked eye.

Buying Tips for Man Made Diamonds:

  • Before you purchase a man made diamond, always check to see if the company offers a guarantee or warranty in case the diamond becomes damaged or lost.
  • Just like real diamonds, artificial diamonds should be graded and certified (an exception is cubic zirconia diamonds).
  • If you are looking for an affordable diamond ring, try purchasing a loose diamond and then have it set in an affordable material such as stainless steel, tungsten, palladium, or titanium.
