Even though HCA grades cut more effectively than systems like the AGS, it does not yet factor in symmetry and minor facets. Having found a diamond that scores well, you should employ an expert appraiser to examine the stone. If you decide not to, then at least compare the diamond to others and/or view it through an ideal-scope. A score below 2 (Excellent) means you have eliminated known poor performers (more than 95% of all diamonds). Your own personal preference may be for a diamond with an HCA score of 1.5 more rather than one with a lower score of say 0.5. Many diamonds with excellent scores may not be traditional 'ideal cuts' but we believe their value will rise once the GIA establishes its cut standard. This system is being continually fine-tuned and results may change without notice. Garry Holloway FGAA DDT

The red area on this chart represents the lowest HCA scores. Stones near the center of the red region, those with the lowest scores, are often the least affected by small symmetry variations. A shallower stone, on the lower part of the chart, will look darker when viewed from close up, they are not for everyone. Shallow stones have the advantage of a bigger spread. They are better suited for use as pendants and earring stones where they are not usually viewed from very close proximity (a close observers head obstructs light sources that would otherwise be returned). Deeper proportioned stones, near the upper part of the red area, have more leakage. Leakage means reduced light return. A limited amount of reduced light return can contribute to a diamonds contrast. Diamonds with a large area of partial leakage table, seen as a pale pink area with an Ideal-Scope, are best set in open backed rings so light can get in the bottom or pavilion of the diamond. It is possible for light entering the pavilion to leak back out the top as firey dispersed colored flashes. Deeper diamonds that have perfect or hearts and arrows grade symmetry, with scores around 2, will often perform far better than diamonds of lesser symmetry.

后面那些都是网站的General说明…没什么看的必要…主要参数就是前面4个good…综合测评分在4分…后面的评语说的是,只有当价格是你唯一的考量标准的时候才建议买这颗钻…

修正一下前面一条的用词,只有当价格是你最主要的考量标准的时候才建议买这颗钻…后面的大致给你解释下,就是说在这个网站测评分低于2分的钻几乎可以避开世界上大部分不好的切割(大约在95%左右)…最后一段呢就是告诉你钻石测评点落在图上的哪个范围说明了什么,以及超出规定值的某项指标会导致什么后果…不给你一一翻译了…因为我觉得这个测评结果真的没什么必要买

楼主这颗比我的评分还高点,我的4.4分,后面那句话一样的

主要就是说是4分,按数据比例算出来火彩不是很好(低分好),其他都是不用看的,另外就是hca算算玩可以,不用太在意,先按4C、瑕疵、台面挑好再说
