A muhurta is a specific date and time selected by a Vedic Astrologer to maximize the auspiciousness of an event. Muhurtas can be used for buying homes and vehicles, for signing business contracts, and even for when you first begin wearing your astrological gemstone.
Some people like to get a muhurta for when their gem should first be purchased, but we find it’s most impactful to get one for when you actually begin wearing it.
While it’s not a hard requirement to use a muhurta for an astrological gemstone, as it will essentially start working as soon as put it on no matter what, auspicious timing is worth utilizing as it can optimize the results that your gemstone produces.
Not everyone has a Vedic Astrologer to get a muhurta from, so below are the proper days of the week to use for every gemstone. I’ve also included some suggested intentions to focus on and mantras you can recite for further activation. (Learn more about how we bless and activate our gemstones, and how you can do it at home, here.)
For All Gemstones:
Begin wearing the gem on a waxing moon. An ideal time of day is sunrise. (Cycles of increasing light are more auspicious than cycles of diminishing light.)
If doing a Vedic mantra, recite it 108 times. (Please note that there are more sophisticated mantras than the ones listed below, but if you’re new to Vedic practices, it’s fine to use a simple mantra that can easily be memorized. These can also be found on YouTube if you need any help with pronunciation.)
