A Ruby is a pink to blood red gemstone, a variety of the mineral corundum. The common red color is caused mainly by the element chromium. Its name comes from ruber, Latin for red. Other varieties of gem-quality corundum are called sapphires.
All natural rubies have imperfections in them, including color impurities and inclusions of rutile needles known as "silk". Gemologists use these needle inclusions found in natural rubies to distinguish them from synthetics, simulants, or substitutes. Usually the rough stone is heated before cutting. Almost all rubies today are treated in some form, with heat treatment being the most common practice. However, rubies that are completely untreated but still of excellent quality command a large premium.
Some rubies show a 3-point or 6-point asterism or star. These rubies are cut into cabochons to display the effect properly. Asterisms are best visible with a single-light source, and move across the stone as the light moves or the stone is rotated. Such effects occur when light is reflected off the silk (the structurally oriented rutile needle. inclusions) in a certain way. This is one example where inclusions increase the value of a gemstone.

Warum überbieten sich Nutzer selbst?
Bei Abgabe eines Gebotes handelt es sich um den Höchstbetrag, den ein Nutzer für das Produkt zu bieten bereit ist. Unser System bietet dann automatisch im Namen dieses Benutzers und erhöht das Gebot schrittweise, um seine Position als Höchstbietender bis zum angegebenen Höchstbieten zu halten.
Wenn das Symbol „Automatisches Gebot“ angezeigt wird, bedeutet dies, dass unser System aktiv Gebote für den Benutzer auf der Grundlage seines Höchstgebots abgibt. Dies mag so aussehen, als ob die Nutzer sich selbst überbieten würden, aber es liegt einfach daran, dass das System das Gebot aktualisiert, um das Höchstlimit des Nutzers widerzuspiegeln.
