The pattern can be inspired by floral motives or just random setting of kundan or meenakari. The craftsman usually made individual pieces of the repetitive motive and then strung them on a gold chain or raw silk cord. The other option was to connect them via horizontal links.
This is a style of necklace in which the neck piece sits very close to the neck. It is sometimes combined with a choker. It has a repetitive pattern with a constant width of at least an inch or so, which will follow throughout the length of the necklace up till the back or the lock of the necklace.

Originally the Rani Haar was made in Gold and precious stones with very fine finishing of meenakari work on the back but nowadays, you can find imitations in non-precious materials as well.

The Rani Haar spreads beautifully around the neck and shoulders and looks extremly graceful and rich when worn with the Indian saree. The beautiful necklace when worn with a gown for an evening gathering could also look enchanting.
The earrings that you would combine traditionally with the Rani haar are usually very long and heavy with a kanauti or decorative supportive chain that leads up and pins up in the hair. But following the current trends and practicality, a Rani Haar would look best when worn with medium weight earrings with the length reaching no more than the chin at max.
