The Fluorescence of Fine Diamond Jewellery
Fine jewellery such as the white diamond jewellery sold at Hancocks Jewellers will go through a grading process for the cut, clarity, colour, and carat. A lesser known processor, for most consumers, is the diamond fluorescence. Diamond fluorescence is usually only visible when ultra violet light is shown on the diamond. When the light is shown on the diamond you will see a degree of colour change. Even the colourless diamond can have fluorescence despite flawlessness.
When the light is shown to view diamond fluorescence most diamonds will have a blue tint. In some rarer cases the diamond may show yellow. The fluorescence of a diamond can reduce the value of the overall gem. The fluorescence is normally thought to be an inclusion and therefore the price reduction. There are some positive notes though with diamond fluorescence.
At Hancocks Jewellers and with other fine jewellery any diamond with a rating of G to J will not have a lower value. The price will be reduced, but it is considered an improvement on the colouring. It is when the fluorescence appears in the D to F that may affect the diamond overall. It can make the diamond look opaque or give it a lower polish number. Typically in this case the negative aspects will reduce the cost and make the diamond less valuable to consumers.
With fluorescence with a diamond rating of K to M the price will actually increase the price of the diamond. This scale means the diamonds already have colour to them, which means a further tinting helps their rating. Typically K to M will be yellow in colour, so a blue tint enhances the gem. By understanding fluorescence you will be able to choose your white diamond jewellery with a semi- professional eye. Having fine jewellery as an heirloom is often one reason to purchase jewellery.
