Man Made Loose Diamonds (Lab-Created)

MiaDonna's collection of man made loose diamonds, also referred to as lab-created diamonds, pure grown diamonds or synthetic diamonds, are real diamonds. They are chemically, physically, optically, and atomically identical to earth-mined diamonds. Each loose man made diamond is grown in a modern-day lab environment, within a chamber of extreme heat and pressure that mimics the earth's natural growing process.

Our lab-created diamonds are offered in a variety of colors including, but not limited to vivid orange, yellow, pink, blue and white (colorless diamonds). The available diamond cuts range from the traditional Round Cut to Fancy Cuts. We offer an extensive selection of grown diamonds, however if you don't see what you are looking for, please contact us for availability. Every lab-created diamond comes with either GIA, IGI or EGL diamond grading certification. These are REAL diamonds and will test positive on a jewelers Thermal Diamond tester.

Filter by Carat Weight

CARAT WEIGHT

Carat weight is the measurement used to describe the size of a lab-created diamond, lab-created gemstone and/or diamond simulant. On the metric scale, 1 carat is equal to 200 milligrams, or 0.2 grams.

While carat weight can impact the value of a lab-created diamond, it’s important to understand that two grown diamonds of the same weight may have dramatically different values. This is because a grown diamonds value takes into account all of the 4C’s, not just the carat weight.

Filter by Cut

CUT

The cut of a diamond does not refer to shape (e.g. round, oval), it refers to the diamond’s symmetry, proportions and polish. A diamond’s cut is the positioning of facets, which modifies the shape and appearance of a diamond. If a diamond is cut poorly, it will be less brilliant, so diamond cutters have to consider several factors, such as the shape and size of the rough crystal, when choosing a diamond’s cut.

A diamond’s cut determines how it interacts with light, creating captivating visual effects, like…

  • Brightness: The internal and external ‘white light’ that reflects from a diamond

  • Fire: The dispersion of ‘white light’ into the colors of the rainbow

  • Scintillation: Also known as sparkle, the pattern of light and dark achieved by reflections within the diamond

Diamond Cut - Grading Scale:
  • Ideal: A desireable and rare cut that reflects nearly all light that enters the diamond. 

  • Excellent: Reflects nearly as much light as the ideal cut, also very desirable.

  • Very Good: Reflects most of the light that enters the diamond. Priced much lower than an Ideal cut.

  • Good: Still a quality diamond, but a good cut will not be as brilliant as a very good, excellent or ideal cut.

  • Fair (Poor): Diamonds with a cut of fair or poor are typically cut deep and narrow or shallow and wide causing them to lose most of the light out the sides and bottom. MiaDonna does not carry diamonds with cut grades of fair or poor.

Filter by Color

COLOR

When discussing a diamond's color, we are referring to the whiteness, or lack of color present in the diamond itself. The scale of diamond colors is detailed below:

  • Z-N - Noticeable Color
  • M-K - Noticeable Color
  • J-I - Near Colorless
  • H-G - Near Colorless
  • F-E - Colorless
  • D - Absolutely Colorless

Filter by Clarity

CLARITY

Clarity is referred to as the purity or quality of a diamond and is the relative measurement of the inclusions and blemishes as determined by a gemologist using a special scope and a 10x magnification loupe. It is the visibility, number and size of these inclusions that determine the diamond's clarity grade. The better the clarity of a diamond is, the greater the brilliance, value or price of the diamond.

Diamond clarity is measured on a scale from Flawless (FL) or Internally Flawless (IF) to Included (I1, I2, and I3). Each of these characteristics are plotted on a diamond diagram that is included on the diamond's grading certificate.
