When this effect throws flashes of colour, we refer to this as fire scintillation. Flash scintillation comes from bright flashes of light dancing across the polished facets of a diamond. We divide scintillation into flash scintillation and fire scintillation. Viewable with the naked eye, scintillation is the life of the diamond. The effect of light and movement creates scintillation. Scintillation is the play of white and coloured flashes of light seen when the diamond is viewed in motion. In contrast, brilliant-cut diamonds demonstrate greater brilliance and less fire.Ī diamond splits white light into colours of the spectrum, referred to as ‘fire.’ What is scintillation? For example, Emerald-cut diamonds give greater fire but less brilliance. Some diamond cuts exhibit greater fire than others. When we see the colours of the spectrum in a diamond, we call this fire. This means that a beam of white light going into a diamond comes out as a spectrum of different colours. In diamonds, this effect appears as random bursts of colour-most noticeable in bright sunlight. This same effect occurs when light passes through a prism resulting in a rainbow of coloured light. We see the same effect in water droplets when a rainbow forms. As visible light passes through a diamond, it splits into different colours. Diamonds sparkle owing to the effect of brilliance with additional factors. As a result, poorly cut diamonds appear far less brilliant by comparison. Conversely, a poorly proportioned diamond leaks light. As a result, reduced proportions resulted in less brilliance. This allowed light to pass through the bottom of the diamond. But, historically, older cut diamonds featured deeper proportions and 58 facets with a culet. ![]() They’re modern proportions guarantee brilliance in very good and excellent cut grades. Modern round brilliant-cut diamonds feature 57 facets. Light passes back to the eye through the table facet. As a result, a well-proportioned diamond reflects most light back internally. ![]() The proportions and symmetry of a diamond change the way light passes through a diamond. Light bends as it passes from one medium to another- an effect referred to as refraction.Īs this light travels through the diamond, it strikes another surface within the stone, and reflects white light back to the eye. The passage of light through a diamond slows as it passes through the matrix of carbon crystal. Light refraction and reflection in diamonds In the following video, a round brilliant cut diamond sparkles with fire, brilliance and scintillation in a tension setting of our Unity ring design. But few people understand the difference between each of these terms. Most people refer to fire, brilliance and scintillation. For this reason, great time and effort go into cutting a diamond to release not only beauty but its value at the same time. The cut and proportions of a diamond can influence value by as much as 40 per cent. In fact, the diamond engagement ring has become the iconic symbol of love.Ī significant part of a diamond’s value results from the cutting process. At the same time, light reflects from the stone.įor this reason, diamonds provide the ultimate symbol of love. From the rough crystal to the final faceted gemstone, the final result changes the passage of light passing through the diamond. The diamond-cutting process reveals the true hidden beauty of a diamond. From an insignificant crystal in the ground, the true beauty of a diamond comes from the expertise of the diamond cutter. ![]() The process of diamond cutting transforms a diamond and gives it sparkle.
