Zircon (/�ˆz�œrk�™n/; including hyacinth or yellow zircon) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicateand its corresponding chemical formula is ZrSiO4. A common empirical formula showing some of the range of substitution in zircon is (Zr1–y, REEy)(SiO4)1–x(OH)4x–y. Zircon forms in silicate melts with large proportions of high field strength incompatible elements. For example, hafnium is almost always present in quantities ranging from 1 to 4%. The crystal structure of zircon is tetragonal crystal system. The natural color of zircon varies between colorless, yellow-golden, red, brown, blue, and green. Colorless specimens that show gem quality are a popular substitute for diamond and are also known as "Matura diamond".
The name derives from the Persian zargun (زرگ�ˆï¿½†), meaning golden-colored.[5] This word is corrupted into "jargoon", a term applied to light-colored zircons. The English word "zircon" is derived from "Zirkon," which is the German adaptation of this word.[6] Red zircon is called "hyacinth", from the flower hyacinthus, whose name is of Ancient Greek origin.

为什么用户出价高于自己？
当有人出价时，这是某人愿意为产品出价的最高金额。然后我们的系统将自动代表竞标者出价，逐步提高出价直至最高价，以保持其最高出价者的地位。
当出现“自动出价”图标时，表示我们的系统正在根据出价者的最高出价为其出价。这可能看起来像是出价者在出价高于自己，但这只是系统更新出价以反映出价者的最高限额的结果。
