Their hardness is linked with the crystal progress sort, which happens to be one-phase crystal development.
quite a few diamonds fluoresce blue to violet, with fluorescence often in zones (normally a result of twinning). The influence is usually strong sufficient being noticeable in daylight. Yellow stones occasionally fluoresce yellow-environmentally friendly. Some pink diamonds from India fluoresce and phosphoresce orange. The famed Hope diamond, deep blue in colour, phosphoresces deep purple. Most fluorescence occurs in LW; the SW reaction is weaker and similar to LW. lots of diamonds fluoresce bluish white in SW. Blue-fluorescing diamonds might phosphoresce yellow (an "afterglow" reaction). the different diamonds happen to be structured into styles, with varying UV transparency.
by way of example, most white diamonds are discounted in value as a more yellow hue is detectable, even though powerful pink or blue diamonds (including the Hope Diamond) could be dramatically a lot more precious.
