The conception of each Rosan Diamond card provoked a deep investigation, as the cards reflect the greatest artistic trends of time, trends that cross both eras and cultures worldwide. Japan, India, Ancient Egypt, European, artistic trends like Art Nouveau and Art Deco are all honored here, and the chosen designs are the most representative of significant pictorial movements in world art history. There are also cards evoking contemporary artistic images and movements, graphic and abstract compositions. From documents of each time period, the Rosan Diamond card’s designers first carry out two sketches to be used for the card’s front and back – different in their interpretations but harmonious in subject. One of our examples reveals a close adaptation of these celebrated traditional Japanese prints: the feminine subject, Hirohige’s finesse, and the stunning view of Mont Fujiyama in the springtime, the celebrated print series from the great Hokusai.

A special golden alloy was developed purposefully for the Rosan Diamond cards; this alloy confirms to the necessary requirements guaranteeing the optimal combination of resilience and solidity. The main task that craftsmen face at this stage is to ensure absolute proportions and rigidity of resulting golden plates of 0.9 mm. To be able to be used, it cannot be warped, as credit cards require an extreme accuracy of 0.05 mm. The design is then processed through a specially developed computer program where a milling cutter perforates into where the Rosan Diamond card’s delicate stones will be set. This engraving should not exceed 0.2 millimeters. Apart from creating the precise niches, all the decorative work is completed by an artisan’s skillful hand. The small fragile fragments of mosaic are inserted into the Rosan Diamond card’s niches excavated with a milling cutter. The card is then polished to arrive to its nominal thickness. Then an engraver begins the card’s decoration by gouging the gold. This requires a very precise and sure hand; even the smallest mistake can ruin a card. The final polishing is then done, and the card is perforated to accommodate the setting of the precious stones.

A work of art, a technological achievement, a piece of jewelry, a collector’s item – the Rosan Diamond card is all this and more! It could be a membership for a private club, a credit or bank card, or even a preferred shopper’s card! Its versatility makes it an incredibly unique and valuable object, much like the renowned and luxurious Easter eggs of Fabergé. Having one or many of these cards is an incredible joy to whoever owns it…

As a rule the contact pad of the microprocessor used to be a decorative element itself. So it has its own original design included in the whole art composition of the card. Thus, it doesn’t break an artistry of a precious jeweler miniature.

The design of Rosan Diamond cards provides an opportunity of replacement of the microprocessor that allows not only to expand aesthetic possibilities, but also to use a card within various payment systems or banks.
