Welcome back Bertrand, I haven''t seen you for a while. I''m no good with Photoshopping but Iwannaprettyone is our resident expert with graphics. I hope she sees this post.
IWPO,
I think it's better to show 2 separate pictures for the colour change alex stone:
1 with a slightly darker teal stone and a 2nd picture with a slightly darker reddish purple stone.
This is concept I have for my wife and our new child. I like to plan in advance. The sapphire and diamond engagement ring took my about a year to figure out.
The tsavorite is my idea for a nicer/hardier Substitute for daughter #1's may emerald birth stone. Child #2 is due on June 5 - assuming it is not early.... alexandrites are not cheap - so wife better make it into June!
