OUR DIAMOND

DIAMOND

We use lab grown diamonds (synthetic diamonds) made of the same components as natural diamonds. It gives a pure and beautiful shine without impurities.

WHAT ARE LAB GROWN DIAMONDS?

Lab grown diamonds are made under the same conditions as the natural diamonds from which they are mined. It has the exact same structure as natural diamonds.

Natural diamond requires more than 1 billion years of pressure and high temperatures to form. While lab grown diamonds have made this process much more efficient through the application of advanced science and technology.

Physically and chemically identical in structure to natural diamonds, they are indistinguishable from them even by a professional diamond grader and can only be distinguished from natural diamonds with the help of specialized machines.

DIFFERENCES

Lab grown diamonds are made under the same conditions as mined natural diamonds, they exhibit exactly the same physical, chemical and optical properties as mined natural diamonds. The only difference is that the diamonds grown in the lab are being produced in a laboratory on Earth.

Diamond Quality

PRMAL's diamonds

We only use the highest quality diamonds with a minimum of G-Color, Clarity (Scratch) VS2 and Good Cut.

Diamond Type

Type IIa​ = Pure & Rare

All lab grown diamonds are Type IIa, which is the purest form of diamond. Type IIa diamonds are crystallized without impurities and are harder and more brilliant than Type Ia diamonds.

Only 2% of all natural diamonds mined from the earth are Type IIa diamonds, and the larger diamonds, especially the larger ones, have premiums and fetch high prices.

Diamonds are generally described as "crystals of pure carbon only" or "gemstones composed of a single element". In reality, however, many natural diamonds grow deep in the ground, taking in other elements and other elements as they crystallize over the years. Most of them are nitrogen, which is an element found in many parts of the earth.

How is a lab grown diamond made?

BENEFITS

  1. Ethically sourced

    Because it is made in a lab, it is guaranteed to be conflict-free and ethical, and there is zero chance of conflict diamonds. With mined natural diamonds, we cannot guarantee it. And it has the advantage of being a sustainable source of supply for the next generation.

  2. Sustainably grown

    Compared to mined diamonds, lab grown diamonds have no impact on the environment, do not pollute water bodies or degrade the soil.

  3. Competitive prices

    Our lab-created diamonds are 30-40% less expensive than their natural diamond counterparts mined from the ground, with the elimination of intermediate costs due to the short supply chain.

How environmentally friendly is it?

  • 1.Excavated land

    Natural Diamond

    Thousands of acres of soil moved during diamond mining
    0.00091 hectares/carat

    Lab Grown Diamond

    No soil movement
    0.00000071 ha/carat

  • 2.Carbon emissions

    Natural Diamond

    High air pollution
    57,000 grams/carat

    Lab Grown Diamond

    No impact on the environment
    0.0028 grams/carat.

  • 3. Amount of water used

    Natural Diamond

    A lot of water.
    480 liters (0.48 m3)/carat

    Lab Grown Diamond

    Water use is seven times lower
    70 liters (0.07 m3/carat)

  • 4. Lost time injury rate

    Natural Diamond

    A high-risk work environment
    8 days per year / 100 employees

    Lab Grown Diamond

    High employee safety standards
    0 days per year / 100 employees
