The most cheapest, money-saving device anyone can buy is a 10-power
loupe, why so? Here are my three loupes.
Supposing you are setting a 'humongous' 1+ ct. Princess-Cut diamond &
halfway through your setting, you see that the stone is damaged.
It's your fault!!!..(even though you didn't do it!) Cost to repair
=>$1,000's out of your pocket.
What should you have done first? Us a loupe & examine every corner of
the Princess stone, even on the Pavillion-facets underneath.
Those four-corners are areas that might be the easiest to get broken.
Go to my 2 photographs & see the other places that breakage might
Re; Girdles are also prone to getting broken, but those four corners
are the worst! Basically, you have 14 places chipping can & will
occur. If it takes you minutes to examine a stone, let the client
know of any defects & get them noted!!!
