As a Vedic astrologer, Neelam should be worn with great caution, as it carries the intense energy of Saturn. It is traditionally worn on the middle finger of the right hand, as this finger is governed by Saturn. The most auspicious time to wear it is on a Saturday, preferably during Shani Hora, after proper purification and energization rituals.
As for combining it with Pukhraj, one must be careful. Saturn and Jupiter have a neutral to mildly conflicting relationship depending on the chart. Hence, wearing both together is only advised after a detailed horoscope analysis. Without proper guidance, such combinations may create imbalance rather than benefits. Always test Neelam for few days before wearing it.
