Diamonds, precious and exclusive stones and rare pearls can be admired and purchased at Luca 1959, the high-class jeweller’s specialising in certified gems. All that is rare is precious, although not everything that is precious is rare. An object, however costly, if produced in series of tens or even hundreds can never be as exclusive as a unique diamond. At Luca 1959 the idea of preciousness is strongly linked to the concept of rarity and exclusivity. In nature no two diamonds are alike, and stones above three carats are merely an infinitesimal part of the market. Luca Alfonsi, a gemmologist registered with the GIA (Gemological Institute of America), offers his customers jewels, diamonds and pearls not customarily found anywhere.
