- Buyer Beware! You should not expect to find an intensely saturated blue tanzanite of less than 2.50 carats. The color of a fine, 1.00 carat tanzanite is likely – at darkest – to be a medium blue or GIA 5/6 & 6/5.Consumers should be wary of online retailers selling smaller stones – between 0.50 to 2.50 carats – as ‘investment grade’ or GIA 6/6.n the 35.00+ carat size range, carat weight and rarity become the most important value factors. Tanzanites over 50.00 carats are almost exclusively graded with a tone and saturation above the dB/bv 6/6 listed as optimal for stones under 30 carats.
