Beautiful Inside and Out
There are two ways cutters achieve diamond beauty.
The standard way is to cut for external symmetry using fixed formulas for outer dimensions and workmanship. It is assumed that if a diamond meets specifications for proportions and faceting, full beauty will result
That is not so. Remember that diamond beauty depends on light return (brilliance, fire and sparkle). So cutters must address this factor directly. Just because a diamond is well contoured and crafted doesn't guarantee it is reflecting light to the fullest degree.
To ensure maximum light return, EightStar Diamond Company. cuts for optical, rather than external, symmetry. This means that diamonds display perfect light-reflection patterns in a special instrument called the Firescope. This
eight-rayed pattern is proof of full light return.
By continually checking diamonds in a Firescope, EightStar cutters make sure their labors lead to maximum brilliance, fire and sparkle. At the same time, they produce superbly crafted diamonds. So you get the best of both worlds: external and optical symmetry.
