How large does my deep rb face up?

[deebee82]

Hi all,

Just a quick query.. I've got a fairly deep rb, 1.26ct, that faces up at 6.84x6.89. Can anyone help me as to what sort of (ideally cut) carat size it faces up? Im estimating less than 1.2?

Thanks!

Hi

Here is a carat size conversion chart https://www.pricescope.com/community/threads/mm-to-carat-stone-conversion-chart.17578/. Hope it helps!

A 1.26 with Tolkowsky angles and 61% depth will have a spread of about 7.00mm. Your 1.26 is facing up like a 1.18 with the above geometry, so your estimate is correct.
