Dfference between lab diamonds, moissanite diamonds and crystal diamonds

Dfference between lab diamonds, moissanite diamonds and crystal diamonds

  There are many different types of gemstone on the market, each with its own unique characteristics and varying prices. In the case of the dazzling diamond, it has always been a woman's favourite, and for thousands of years it has not only represented a person's status, but also symbolised the enduring love and vows that have always been coveted by mankind.

  It is undeniable that the advantages of diamonds have led to their high price tag, and so a variety of diamond-like alternatives are constantly appearing on the market at affordable prices, with multiple options not only saving consumers' wallets but also satisfying psychological needs.

  We've talked most about lab diamonds, but have you heard of moissanite diamond(Square Silicone Moissanite, high carbon diamonds) and crystal diamonds? Although these stones often have the word 'diamond' in their commercial nomenclature, they are not essentially the same as a diamond.

What is a natural diamond?

  A natural diamond is a crystal made of carbon, also known as 'diamond', formed by nature over tens or even hundreds of millions of years at high temperatures and pressures within the earth.

What is a lab grown diamond?

  A Lab Grown Diamond (also known as a synthetic diamond) is a diamond that has been grown in a laboratory using the most advanced technological processes. Lab diamonds have the same physical and atomic structure as natural diamonds and are comparable to, or even superior to, natural diamonds in terms of quality under the 4C's of diamonds.

What is a Moissanite diamond?

  Moissanite diamonds are also known as "Belgian Mosin diamonds, high carbon diamonds", formally known as silicon carbide. Moissanite diamonds are chemically composed of SiC, a silicon carbide, nearly colourless, with a refractive index of 2.56-2.69, a dispersion of 0.104, a birefringence of 0.043, a hardness of 9.25 and a density of 3.22 g/cm3. The Moissanite diamonds currently on the market are all artificially cultivated and have a relatively low technical content, making them very inexpensive. They attract many people because of their sparkling brilliance, the intensity of the fire they emit and their low price.

What is a crystal diamond?

  Crystal diamond (Crystal，Rhinestone) is what we often call 'rhinestone', or 'imitation diamond'. It is neither a crystal nor a diamond, and the common crystal diamond can be divided into different materials, including artificial crystal, glass, resin and acrylic, etc. Although the visual effect is as dazzling as that of a diamond, the essence of the diamond is very different, and the price is naturally very different.

  The main uses of crystal diamonds are very diverse, such as decorative objects, chandeliers, handicrafts and everyday objects. When buying jewellery, you will often find that these jewellery pieces are decorated with a lot of small, bling-bling, clear stones that look sparkly and shiny.

  To determine the difference between a diamond and a moissanite diamond, you can rely on the following points.

  Judging by the "brightness": natural diamonds are single-refractive stones, while moissanite diamonds are birefringent, so if you look through a loupe, you will see that moissanite diamonds have strong dispersion and that the faceted prisms will have double shadows, which will still appear even if you change the angle of observation.

  Judging by the "fire": when white light passes through the diamond's facets, it disperses into a rainbow of colours. Under a spotlight, shaking or turning the diamond upside down reveals flashes of red, blue, yellow or orange fire. Thus, a diamond and a moissanite placed next to each other in bright light may produce a more intense flicker of colour and be more colourful than a diamond.

  Judging by 'weight': If you compare a diamond of the same size with a moissanite, the moissanite has a lower density and specific gravity, so it will weigh approximately 15% less than a diamond.
