I should have been more specific of course.
I think that one must look at ‘top quality’ goods, 8.5-9/10 or better.
However, you make a great point about SIZE!
I’ve bought and sold countless 3ct+ very fine quality tsavorite, and at least 25-30 5ct+ very fine tsavorites.
However, I’ve never even seen a 5ct+ top colour Russian Demantoid with horsetail and I’ve only seen one of colorless garnet and it was not terribly impressive being below 1ct and fairly included…
I think that ‘like for like’ is fair. 1ct, fine colour, very good clarity (or horsetail) 8.5/10 or better
