the morganites at JTV can be very pretty, they vary from almost clear, to a very pretty peachy-pink.
whenever i order loose stones from JTV, i try to order at least three identical ones - so i can pick the prettiest and return the others :P
but morganites don't sparkle like a diamond... they do sparkle, but it's a more subdued sparkle.
plus, remember that they're emeralds, so they are softer stones and not really meant for daily wear.
i've spent SO much time & money hunting to find just the right shade of pale pink... the Very Lightest Pink available from WinkCZ is sooo close. in some lighting, it's cotton candy pink, and in other light it's just a hint of pink.
but that's not helpful if you're only looking for a gemstone, is it?
