Simply a new kind of diamond


If a laboratory grown diamond…

  • has the same characteristics as a mined diamond
  • is of the same quality as a mined diamond
  • has the same beauty and sparkle
  • is environmentally friendly
  • is socially responsible
  • is much more affordable than a mined diamond

Possibly the smartest choice in diamonds?

Diamonds reinvented



Madestones are real diamonds created in a laboratory. Timeless white diamonds and diamonds of beautiful striking color.  An affordable, conscientious and modern choice.

What exactly is a “laboratory grown diamond”?

A laboratory grown diamond is a diamond. There is no difference between a diamond occurring naturally and a laboratory grown diamond except ‘origin’. The most respected diamond grading laboratories the Gemological Institute of America, HRD and the International Gemological Institute provide diamond grading reports certifying that laboratory grown diamonds are exactly the same as natural occurring diamond except that one is created by science.

Simply put, it is a real diamond!
