What Is a Lab Grown Diamond?
As clear from its name “Lab Grown Diamonds” are types of diamonds created in laboratories, in controlled machinery, in a special environment. These diamonds are similar to real diamonds, but lab created. Real diamonds are rare, and taken from the earth beneath. Both have similar qualities, chemical and physical properties. Real diamonds are purely made of Carbon, so manufacturers arrange Carbon atoms through high pressure and high temperature which is called HPHT to create diamond crystalline structure.
So, this complete process creates diamond crystalline structure and makes the lab grown diamonds same as real diamonds, with similar physical, chemical and optical properties, which can shock anyone. Remember, lab grown diamonds are not moissanite, or Cubic Zirconia, they are different diamonds, stimulant or diamond alternatives. That is why FTC mentions for American shoppers, only purchase from those sellers, who tell the difference not to hide its different qualities.
What Is Moissanite?
Moissnaite is a separate thing, actually it is a diamond alternative not a real diamond. It is very rare on earth but very famous in the diamond market. That is why manufactures created these alternative diamonds in laboratories to fill the market cap. It is not a pure carbon but created with the mixture of Silicon and carbon called silicon carbide. But why do people call it a lab-grown diamond? Lab grown diamond and lab-grown diamond alternatives are two different things. One is created with pure carbon which are real diamonds, the other is created with silicon carbide which is a diamond alternative not a real one.
But why are moissanite diamonds more famous than any other diamond alternatives like Zubic Zerconica? This all is because of its sparkle, shine, rainbow fire, larger size then real diamonds and affordable price. It has 9.2 hardness on Mohs scale, very near to the real diamonds which is 10. That is the reason moissanite bends the light strongly and creates heavy flashes and rainbow fire, and this is the reason it catches american shoppers eyes in the diamond market.
Is Moissanite a Lab Grown Diamond?
No, but a lab-grown diamond alternative. I was in the same confusion a week ago, but then I searched throughout the internet, and watching different videos and realized that these both stones are created in laboratories but one called lab grown diamond and the other one I mean the moissanite called lab-grown diamond alternative.
Lab-grown diamonds contain carbon same like diamonds taken from the earth, so there is no difference between rare diamonds and lab-grown diamonds because both have similar shine, color and sparkle like genuine. On the other side, a lab-created diamond alternative (moissanite) contains silicon carbide, makes it different from the real diamonds and has distinct diamond features.
That is why FTC forces the jewelers to explain the difference to the buyers between diamond alternatives and real lab grown diamonds.
