Other Blue Sapphires

Heat treated material. Average brilliancy of 40% to 60%. Add to 20% or deduct to 10% for other cutting. Prices for ovals and cushions. Add 8% to 10% for rounds and pears. Add 10% to 20% for emeralds and marquis. Note: If certified Burmese and untreated, add 50%, except fair or lower grades. Typically, mid-quality untreated blue sapphire will sell for 20-30% more than a treated stone of the same quality. Top-quality unheated stones could get a premium of 50% or higher, especially if they're large.
