粒石有螢光反應
價錢黎講偏貴
你呢個價錢已經可以買到無螢光反應
仲要係Medium blue
Besides that, the strength of the fluorescence does not influence the integrity of the diamond. But as the fluorescent glow is usually blue the fluorescence can upgrade diamonds of I-M color by appearing whiter. That is why we see in the industry that I-M diamonds sell better with a medium to very strong fluorescence.
Extreme fluorescence does impact the diamond appearance by being oily or hazy. I-M diamonds benefit from some fluorescence to appear whiter.
Bottom line, Faint Blue Fluorescent diamonds improve the appearance of color in the diamond as they never appear hazy. Same for Medium Blue Fluorescent diamonds, they will barely show no sign of haziness. Just be careful when you choose a very high color like G in the Medium Blue Fluorescence Range, this could be the worst case scenario.
即係點? 藍+黃變白會仲靚左? 因為買左都唔會賣, 最緊要係好睇?
