Yellow Safire as we all know is a Gemstone that represents the benevolent gas giant Jupiter. which also called Budh, Brehaspati in Sanskrit.
The vedic interpretation of Jupiter or Guru is that of a senior aged Brahman with a large benevolent Heart, a kind and gentle teacher with immense potential to bless his adorers with unbelivable quantum of goodness. Wealth, peace of mind, cheerfulness, problem solving, favouring, clarity of thought, kindness, sencierety, higher education, academic excellence, fame,status, abundance etc;are a good few examples of what the planet Jupiter could bestow on people who worshipp him and wear a Yellow Safire, prescribed by a vedic astrolger after careful study of the Individuals birth chart or Kundali.
However any or all Yellow safires may not bestow the attributes. There are certain parameters that the stone in question must satisfy to be energised and worn with reverence.
Size is a good place to start from. Yellow safires are cut and polished in a large array of sizes, begining with small pieces (usually round) of a 2-5 cents each to a colossal sizes exceeding 30 carats a piece! Vedic astrolgers calculate the precise weight of the stone to be adorned by a paticular individual, depending on planetary positions on their Birth charts. The smallest size advocated? is 1.25 Rathi about 1.00 Carat in todays weight scale. It is fake aqua ugg australia boots sale called Sava Rathi in Sanskrit. Stones below this weight is consider fit for Ornamentation fake aqua ugg australia boots sale only. Smaller the stone lesser the cost, however the option for choosing small stones amounting to 1.25 Rathi is not encouraged,and a single piece of 1.25 Rathi is favoured. As to why so? I am as baffled as you are. Importantly most Astrologers in Northern India use the Rathi scale and not carat. I must reiterate that the stone should be Sava Rathi, that is 1 carat+/- and above,stones that work out say 1.75 Rathi are barred, so are 1.50 Rathi. The stone shoul be arround 1.25
