Hammerman Bros. Fancy Yellow Diamond Ring
Founded in 1946, the house of the Hammerman Brothers has the reputation for remarkable quality and sophisticated style and the incorporation of very fine gems in all of their jewelry. The post Eisenhower decades brought an informal cluster design to rings. Angularity and a more splintered effect with jagged outline became popular with a shift more towards a three dimensional cluster design.
Surrounding a round natural fancy yellow diamond of about .89 carats (clarity VVS2) is a starburst consisting of twelve (12) marquise cut diamonds of approximately 1.50 carats and thirteen (13) emeralds mixed rectangular and marquise cuts of about 1.25 carats. In addition, two (2) round brilliant cut diamonds (of an estimated .30 carats) joins the array in the creation of a jagged outline of a floral bouquet bursting with precious gems set into an 18k yellow gold and platinum topped stylish mount. Sensuous split shoulders of 18k yellow gold are each accented by a row of emeralds.
Accompanied by gemological lab certificate (see "More Details").
