A GIA Laboratory report # 21836919, dated March 11, 2008, stating G* color (This diamond has been processed by high pressure/high temperature (HPHT) to change its color), VVS1 clarity, and weighing 4.05 carats. Gross weight 5.00 grams.
Length: 16 inches

High Pressure High Temperature Treatment (HPHT)

The invention of the High Pressure High Treatment (HPHT) process dates to the 1990s when scientists, experimenting with ways to permanently alter the color of some gem quality diamonds, created a complex treatment process that, in its simplest form, is a way of taking high clarity lower color diamonds and transitioning them into more eye-pleasing gems ranging from pink to blue, green, yellowish-green, yellow and colorless.

HPHT Diamond Facts:
· HPHT is permanent.
· The Federal Trade Commission (FTC) requires that HPHT be disclosed.
· Most HPHT diamonds weigh over 1/2 carat.
· HPHT diamonds should cost less than similar natural untreated diamonds having the same grade.
· Gemological Institute of America (GIA) grading reports now indicate when HPHT treatments are detected by stating "HPHT Annealed" or "Artificially Irradiated" in the Origins portion of a report.
