Welcome to SuchenGems!
Black diamonds are rare, valuable, and opaque diamonds that are made of carbon. They are also known as carbonados.
Appearance
Black diamonds have a high luster and opaque appearance
They can appear metallic due to their deep color and shine
They can be black, dark gray, green, or brown
They have an uneven surface, even under magnification
Composition
Black diamonds are made of carbon, graphite, and amorphous carbon
They have natural inclusions of graphite, pyrite, or hematite
Hardness
Black diamonds are very hard and measure a 10 on the Mohs scale of mineral hardness
This makes them difficult to cut and polish
Origin
Black diamonds are found in alluvial deposits in equatorial regions, such as Central Africa and Brazil
Small amounts have also been found in Venezuela and Eastern Australia
Uses
Black diamonds are used in engagement rings, bracelets, pendants, and earrings
They are popular in fashion and are often seen on red carpets and at award shows

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。
