While choosing the Weight of Gemstone, one must take 4 major points into consideration.

• Body-Weight of the Wearer.
• Quality of the Gemstone you are taking.
• Stone should be big enough to make skin-contact while wearing.
• Stone should not hamper regular Lifestyle.

Therefore, weight range of 3 Carats and above gemstones are most widely worn. Any stone below 3 Carat is too small to make skin-contact. Any stone above 8 Carat might become too bulky to handle.
