The fully integrated cover sensually follows the form of the sapphire crystal underneath to create a canvas for artists of many mediums, e.g. gem setting, guilloche, miniature painting, enameling, engraving to ‘paint’.
Invisibly set diamonds
The craftsmanship required for invisible diamond setting is even more demanding than most in that it requires not one but two skilled artists: gem setter and diamond cutter.
To be invisibly set, each and every diamond has to be carefully grooved, with each cut running the very real risk of breaking the stone. However, while invisibly set diamonds are very difficult to accomplish, the effect is spectacular as, without visible support, the gems look larger and light can reflect and refract throughout unimpeded in an explosion of brilliance.
And besides the sheer transcendental aesthetical magnificence of a cover and lugs blanketed in 100s of stunning diamonds, they also provide a practical advantage in creating an extremely scratch resistant case.
