Diamond Engagement Rings & Wedding Bands from Culet Jewellery Auckland
The GIA Colour Scale extends from D (colourless) to Z (light yellow or brown). Although many people think of gem quality diamonds as colourless, truly colourless diamonds are actually very rare. Most diamonds used in jewellery are nearly colourless with tints of yellow or brown.
Colour grades are determined by comparing each diamond to a master set. Each letter grade represents a range of colour and is a measure of how noticable a colour is.
Fluorescence Some diamonds can emit a visible light when exposed to ultraviolet radiation, but fluorescence is not a factor in determining colour or clarity grades. However, a description of its strength and colour is provided on GIA Reports as an additional identifying characteristic.
All Culét's diamonds are sourced from registered respected diamond merchants that proudly adhere to the standards set by the Kimberly Process. This process guarantees every diamond we sell is 100% conflict free and GIA certified. We hold this in the highest regard and will continue to support and only sell conflict free stones.A common question asked is, "Where are the diamonds from?". Our registered merchants purchase stones from mines all over the world: Australia; Russia; Canada; and India. For more information about this visit www.diamondfacts.org
