18ct White gold Laboratory Grown Diamond studs with 2 x 0.80carat.

These are not stimulants.  They are diamonds grown in a Chemical Vapor Disposition Chamber.  You can not tell the difference between natural and Man grown.  As a Gemmologist I can tell the difference by using fluorescence and polarized light.  They are new technology and make large diamonds  far more affordable.  Normally these ear studs would be about $10K
