and semi - precious stones. Precious stones are diamond, ruby,

sapphire, yellow sapphire, emerald, etc. Semi - precious stones

are tourmaline, peridot, tanzanite, garnet, opal, spinel, zircon,

aquamarine, pearl, etc.

cut. Therefore, remember to inspect their quality by using a 10X

the weight and percertage of the material, craftsmanship and

designs.
