Hey Guys!
So, I have a couple of general questions (without a specific ring or stone in mind).
In your experience, do the bow ties that diamonds typically have in pear shapes show up as apparently in colored stones? Does the specific color minimize the effect at all (e.g., will it show more in yellow than in blue?). Any tricks to avoid them? I've read below 60% depth and they get larger, 62-63% is a bit of a sweet spot, and that 66%+ just results in a darker stone but minus the bow tie. Does that lw ratio on the pear impact it at all?
And…berylium, in regard to yellow sapphires - what are your thoughts? From what I gather, it's very typical for yellow sapphires to have been treated with beryllium - is it pervasive enough that one should assume beryllium if there has been heat, absent an AGL or GIA cert to say otherwise? And, I've read conflicting things about whether or not the color is stable - from: beryllium is permanent and the color is stable to beryllium-treated stones fade over time. I'm assuming it's best to avoid all together, but what has your experience taught you?
And, on yellow sapphires generally - I feel like a lot of them look to have a bit of an orange tint - is it possible find them in a more just yellow (like fancy light yellow/canary yellow) without the warmth that the orange brings to it?
Thanks so much for any thoughts, opinions, information you may have to share!
PS - I might have been inspired by pregcurious's new stone (please take it as flattery!)
