Have you heard about the Ideal Scope Image?  Do you think that the vendor can provide this?

Many thanks for your help!

HI,

你好!我會選擇第1粒鑽石,
有聽過Ideal Scope Image,好似像八心八箭筒,但要用其他照明先會顯示光的强弱程度和漏光位置,
但我都沒有買過,我記得網上是有得買,但忘記在什麼地方!

Thanks for your valuable advice.  But I am just afraid the first stone 62.6% depth will be a bit deep.

sam

hi,

你好!我都知道,但整體上所有數據,我都較喜歡第1粒,
你擔心我都明白,但你有沒有看過現貨,這樣比較你會清晰些.

thx

sam

Thanks alot, Sam.  I saw the 1st stone before but actually I can't tell any different.  I don't have much knowledge about diamond.  I always believe the GIA Cert.  But my friend told me even if two stones have the same ranking (3 Excellent), the light return, fire, scintillation and spread will be varied.  So the proportion does matter.  Be honest, I have no idea about what she said but she said the Ideal Scope Image will help for the final selection.  It is quite common for the vendors in the States to provide such image to the customers.  

I am quite surprised that the diamond runs out so quickly.  The 3rd stone has been sold already.  I just got the GIA Cert yesterday morning but at the evening it was sold.

Just out of my curiorsity. If all the three stones cost almost the same, will it affect your decision making?

Thanks alot

sam

HI,

你好!其實我之前沒有考慮價錢問題,我只是喜歡第1粒的數據,
如果價錢一樣,我都會鍾意第1粒.
