Ask the jeweler if the diamond has been treated. Deep sea divers and surfers like Titanium rings particularly because of this high corrosion resistance to salt water we even came across a mention of swim shorts made from Titanium fabric which provide a degree of protection from shark bites but cannot confirm the existance of such. Uses for Titanium - apart from GETi rings, Titanium has many uses, golf clubs and spectacle frames are made from it, surgical implants, aerospace, marine and motor industry applications even paint, to name but a few.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality The ideal cut diamond is a very precise mathematical equation, where diamond proportions and angles are cut to optimize the diamond's superlative optical properties, in particular it's high refractive index and color dispersion, to create a diamond of unequaled beauty with perfect balance of brilliance and fire. In layman's terms, the diamond is cut to make it the most beautiful diamond so it retains its intrinsic value.
Color Diamonds of E color are virtually colorless. Only less than 0.7% of natural diamonds have this color. Diamonds of this color grade will appear colorless even when observed face down against a flat white background.
Clarity Inclusions and external blemishes in diamonds of SI1 clarity may be easy to spot under 10X power magnification. Location of the inclusions greatly affect their visibility to the naked eye. SI1 diamonds of good color produce as good of a sparkle as the more expansive VS graded stones of lower color. Excellent bargains may be fond in this category.
