Clarity in the diamond may be improved by filling up the cracks with molten glass. First trials of the rings, although basic, were good due to the high experience within the company in the field of precision engineering. Also please be advised that resizing rings made from Aircraft Grade is totally impractical, so you should be wary of companies boasting about this material as it will be extremely difficult to resize a Titanium ring made from this.
