Hyacint er sammensat af zirconiumsilikat, med et højt brydningsindeks på 1.78-1.987, og en meget stor dobbeltbrydningsforskel på 0.059. Så længe du bruger et forstørrelsesglas til at observere fra skrivebordet, du kan se ridgeline af den nederste del af den dobbelte skygge, so it is easy to distinguish from diamonds and dispersion The rate of 0.039 is quite similar to that of diamonds, so the fire after cutting is very good, vægtfylden er 3.9 til 4.73, which is higher than that of diamonds, og hårdheden er 6.5 til 7.
Zircon has colors such as colorless, gul, blå, grøn, orange and brown. The most common colors of hyacinth are gray-brown and red-brown. Colorless and green hyacinths are very rare. Brown zircons will become colorless or blue hyacinths when heated to 800°C to 1000°C, but This treatment is not stable, and the color will change again after sun or ultraviolet radiation.
Colorless hyacinths are mostly cut into diamond brilliant cut (Strålende), and other colors of hyacinth are cut into brilliant cut or emerald cut.
The most important identification basis for hyacinth stone is the obvious birefringence difference. Observing the bottom facet ridgeline with a magnifying glass through the desktop will have a double shadow phenomenon, which is easy to distinguish from diamond. Derudover, the hardness of hyacinth stone is lower, so the luster is worse than that of real diamonds, and the ridgelines at the junction of facets are also easier to wear.
Blue hyacinth stones are the most popular in the market. Generelt, hyacinth stones have very few inclusions, so try to choose hyacinth stones with high clarity. The price of hyacinth stones is very different from that of diamonds. Choosing hyacinth stones can buy larger stones with a lower budget.
In the colored gem channel of Baolong.com, there are quite a few large-grain zircons. They have different shapes and colors. They are all natural, and some have third-party inspection certificates. These zircons are also very rare and precious, suitable for wearing and collecting.
