Is the inside of a diamond ring stamped with the diamond size?
noSometimes jewelry manufacturers will stamp the inside of rings with numbers indicating the weight of a main diamond, especially a solitaire, for identification purposes. I have seen it done. Probably not a common practice though. If you have specific numbers stamped inside of a ring, list them here for possible interpretation.If there is an 8 digit number followed by another set of numbers, you are probably looking at the GIA number, which is usually followed by a 2nd set of numbers which is the carat size of the diamond associated with that number. For example 12345678 1.25 would mean you have a GIA certified diamond (Gemological Institute of America) weighing 1.25 carats. At least that is how my diamond is marked on the inside of my ring.NB: Since it is so easy to separate a diamond stone from the metal in which it is mounted, you can only trust the GIA certificate for a diamond stone as the true indicator of its value. Trusting the markings on the jewelry's metal to indicate the size/ quality of its diamond is naive..

How much money would a one inch cubed piece of diamond cost?
The price would be determined by the carat weight, the clarity and the colour of the diamond you want to buy in this cut. (An inch is about 2.5CM or .0254MM: a round, 20-carat gemstone measures only .0176 -- and you would purchase such a diamond at an auction, because of the rare size.) Insofar as a gem-quality stone is concerned, you may not be able to find a raw stone large enough to accommodate this cut, since about 60% of the raw stone is lost in cutting. As well, finding an industrial-quality diamond -- a raw stone -- of this size may be difficult.

Why is it important to use diamond quality reports?
If by 'report' you mean a certificate from a gemologist, the import of this document certifies the quality of the diamond in terms of its clarity, colour, carat weight and excellence of its cut. Every diamond is unique, and especially with diamonds weighing more than one carat, a gemologist's certificate can reflect the monetary value of the gem.
