Spinel is a durable and brilliant gemstone found in a wide variety of colors, including red, pink, blue, purple, and orange, which is the result of trace elements like chromium and iron. It is a hard mineral, ranking 8 on the Mohs scale, making it suitable for jewelry, and is characterized by its cubic crystal system and octahedral shape. Historically, high-quality red spinels were often mistaken for rubies.
Appearance and composition
Color:
Spinel comes in a vast range of colors, with some of the most sought-after being vibrant reds and pinks, which are caused by chromium. Other colors include blue (from iron), violet, green, orange, and black.
Composition:
It is an oxide mineral composed of magnesium, aluminum, and oxygen, with other trace elements influencing its color.
Brilliance:
Spinel is known for its brilliance and vibrancy, thanks to its high refractive index.
Physical and geological properties
Hardness: It has a Mohs hardness of 8, making it a durable choice for jewelry.
Crystal system: Spinel belongs to the cubic crystal system and often forms in a perfect octahedral shape, which resembles two pyramids joined at the base. The name "spinel" comes from the Latin "spinella," meaning "little thorn," due to its sharp crystal formations.
Refractivity: Spinel is a singly refractive mineral, meaning it doesn't split light into two rays.
History
Confusion with ruby:
For centuries, many famous red gems were thought to be rubies, but modern gemology has identified them as spinels.
Underrated status:
Spinel was historically overlooked and undervalued, partly due to this confusion and being one of the first gems to be synthesized.

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。
