Both the sea sapphire and the topaz belong to the "blue tone" gem. Generally speaking, the crystal of the sea sapphire does not have the topping of the topaz. The floc is a lot of color and shallow. This is definitely a sea sapphire. This is a very good difference. The difference is that the high quality of the sea sapphire, floc, ice cracks are very few, the crystal is also very transparent, this sea sapphire and topaz is more difficult to distinguish. In the market, if the crystal and color can be compared with the topaz, the price of this blue sapphire is definitely high, almost several times that of the same quality topaz, so there are many unscrupulous merchants taking the topaz as a sea sapphire. Deceive consumers, now Xiaomu teaches you a few tricks, let everyone know how to distinguish between Hailanbao and Topaz: 1, color: Topaz is generally yellow-brown - brown yellow, light blue - blue, red - pink and colorless, very few in green tones. It must be pointed out that the color of some topazes currently on the market is the result of irradiation treatment and heat treatment. Some blue topaz on the market is made of natural colorless topaz which is browned by radiation and then heat treated to give a blue color. Brazilian pink and red topaz is the heat treated yellow and orange topaz of the property. Aquamarine: Most of the aquamarine is light blue with a greenish tint, and the color is like the shallow sea of ​​the resort, fresh and pleasant. The color is sky blue to sea blue or green blue, which is best for bright and clean, bright blue to light blue. Deep blue sea sapphire is definitely not cheap, don't be cheap. The blue topaz is a very affordable blue gem. 2. Density: Topaz is 3.59 g/cm3, zircon is 4.69 g/cm3, the density is obviously too large, and the handcuffs have a heavy feeling. Under the magnifying glass, the zircon and topaz can be seen in the corners of the bottom facet, and the aquamarine is not very clear. Zircon dispersion is high. 3, crystal form: topaz oblique square column, zircon square column. Although the colors of artificial glass and artificial blue spinel are similar, they are all homogeneous and have no dichroism. 4. Characteristics: The characteristics of aquamarine are sky blue, sea blue, glass luster, less inclusions, clean, transparent, weak dichroism, hexagonal columnar crystal form. Topaz belongs to the orthorhombic system, transparent to opaque, with obvious trichromaticity, columnar crystal form, cylindrical surface often with longitudinal stripes, and the topaz from the sand mine is mostly abraded into an elliptical shape. 5, inclusions: natural aquamarine, most have cracks. Most natural aquamarines have a lighter blue color, while topaz is relatively less polluted and has more than one color. If it is not easy to identify, or buy it in a branded store, especially if you buy it online, you should pay attention to it. 6. Hardness: The hardness of aquamarine is greater than the hardness of topaz. Its texture is brittle, and it is afraid of high temperature. At high temperatures, aquamarine is easy to burst, and it will fade when it is baked. 7, the price: If the color is very deep and the price is not expensive, it is basically impossible to aquamarine. Most of the current aquamarine colors are light, almost colorless, and the price of quality is very high, which can reach 10 times that of topaz. 8. The best method for identification of aquamarine and topaz is density. Topaz sinks in heavy liquid of diiodomethane (density 3.32 g/cm3), while aquamarine floats on diiodomethane. In addition, some special inclusions of topaz can be used, but they need to be identified by microscopy. Evaluation and purchase of aquamarine. The factors are color, transparency and weight. The color is deep, flawless, and the weight is good. Aquamarine is characterized by sky blue, sea blue, glass luster, less inclusions, clean, transparent, weak dichroism, hexagonal columnar crystal form. Avoid impact when wearing.
