Grading questions

Q. How is it possible for a 2.20 ct. pigeon-blood red ruby to cost less than a 1.50 ct. light red ruby?
A. As indicated in the description, the 1 ct. stone is almost clean, whereas the 2.20 ct. has a visible inclusion.
   
Q. I saw on your web site a 1.21 ct. fine royal blue sapphire priced at only $680, and I saw another sapphire, also fine royal blue but in 1.15 ct., which was priced at $1730. How is this possible?
A. Because in the descriptions, the 1.21 ct. has its luster rated as good, whereas the luster of the 1.15 ct. is excellent; also the 1.21 ct. has color bands and the 1.15 ct. is clean.
Q. On your web site I saw a 30 ct. extra fine, green emerald that was cheaper than a 4 ct. grass green emerald. How can this be?
A. In the descriptions, the 30 ct. extra fine, grass green emerald was slightly included and not so bright. The 4 ct. stone, on the other hand, was almost clean, very bright, and full of brilliance.
   
Q. What is the difference between the grades: Ideal Cut, Premium Cut, etc.?
A. The terms "Premium Cut", "Tolkowsky Ideal Cut", and "Excellent Ideal Cut" apply only to round diamonds. Stones receive these grades according to certain angles of cuts and certain percentage standards. For example, Premium Cuts have a table percentage from 58.0% to 61.0%; Tolkowsky Ideal Cuts have a table percentage from 53.0% to 58.0%, and Excellent Ideal Cuts have a table percentage from 52.5% to 58.4%. Depth percentages on any stone should not be below 58.0% or above 63.8%.
