1.Color. The dark red orange topaz is the highest value of topaz, commonly known as the emperor topaz. The color is very precious and very rare. Pink topaz and yellow topaz are also common collector-grade topaz, while blue and colorless topaz are suitable for everyday wear, and the collection value is relatively low.
2.Cuts. Topaz is usually long or cylindrical, so it is generally cut into oval or pear shapes. Bright cuts with triangular and kite-shaped facets, ladder cuts with concentric rows of parallel facets. These are the more common cut styles, and are also very popular in the market.
3.Weight. Topaz can be made in a variety of shapes and sizes depending on the cut. Because topaz crystals are generally larger, large carat topaz is common. Generally, if you wear it, choose a small size, the price is not expensive, and it is exquisite and beautiful. But if collection, it is naturally as big as possible.
