When choosing gemstones for your jewelry project, in addition to color, it is helpful to consider the gem's Mohs rating. The Mohs scale of mineral hardness is used to determine a stone's hardness and scratch resistance. This scale ranks stones from a 1 - 10, with diamonds considered the hardest on the scale at a 10 and softer stones like opals considered a 5.5 - 6.5. At Takayas Custom Jewelry, we are happy to offer an assortment of precious and semi-precious stone options. Below each stone's description are the color varieties it is available in.
