Question 2

什么是桌形切工 (Table Cut)? (What is Table Cut?)

Question 5

什么是老欧切工 (Old Euro)? (What is Old European Cut?)

Accepted Answer

随着研磨技术的进步，钻石终于变圆了。OEC拥有58个刻面，与现代圆钻一致，但比例截然不同：它的刻面更厚重，火彩呈块状（Blocky Fire），而非现代的破碎星火。 Wait technology allowed for rounder stones. The OEC has 58 facets like modern rounds but vastly different proportions. Known for its "blocky fire" and deep inner warmth.

Question 6

什么是现代明亮式 (Brilliant)? (What is Modern Brilliant?)

Accepted Answer

由马歇尔·托尔科夫斯基计算出的光学完美比例。所有光线全反射，消除了底尖。虽然极其闪耀，但许多藏家认为它失去了老切工的个性和深邃感。 Calculated by Tolkowsky for optical perfection. Total internal reflection eliminates the culet. While incredibly brilliant, collectors often feel it lacks the personality of old cuts.
