Olmoslar Art Deco davrida nishon uzuklarida tanlangan qimmatbaho tosh edi. Ammo, chunki 1920-yillarning olmosli uzuklari aniq nisbatlarda kesilmagan, ular kamroq yorqin edi. Sariq tusli olmoslar ham keng tarqalgan va chunki ular odatda kechqurun kiyiladi, past chiroqlar qimmatbaho toshning sarg'ish rangini maskaladi, making warmer diamonds acceptable for flappers.
White jewelry was a trend in 1920s, so diamonds were often set in platinum engagement rings. “Old European” cut diamonds were popular because of the geometric influence of Art Deco in jewelry. Ammo, it doesn’t have the sparkle of a modern round-cut diamond today.
