This is a very nice CERTIFIED natural ruby from Madagascar...EYE CLEAN...2,58cts...9,07 x 6,57 x 3,88mm... Heat and filled
For explanation of filled ruby
Small cracks or fractures in a gemstone can interrupt the flow of light through the stone, creating white or "dead" spots in the color of the stone. Sometimes these fractures–if they reach the surface of the stone–will be filled with material that will allow the light to pass through smoothly.
The process of fracture filling ruby with transparent lead glass is a recent innovation that began about 2004 in Chanthaburi, Thailand. Rubies of good color, primarily from Madagascar, that are disfigured by fissures or surface cracks can be "repaired" using heat treatment with lead glass. The refractive index of corundum and lead glass are very similar, allowing light to travel through the stone, improving the color and clarity. These rubies are often found in large sizes at a fraction of the cost of untreated ruby of similar color. So they represent an excellent value in the market, so long as the treatment is disclosed and the price is appropriate.

Warum überbieten sich Nutzer selbst?
Wenn ein Gebot abgegeben wird, ist dies der Höchstbetrag, den eine Person für das Produkt bieten möchte. Unser System bietet dann automatisch im Namen des Bieters und erhöht das Gebot schrittweise bis zum Höchstbetrag, um die Position des Höchstbietenden beizubehalten.
Wenn ein Symbol mit der Aufschrift „Automatisches Gebot“ angezeigt wird, bedeutet dies, dass unser System aktiv Gebote für den Bieter basierend auf seinem Höchstgebot abgibt. Dies kann so aussehen, als würden die Bieter sich selbst überbieten, aber es ist lediglich das Ergebnis der Aktualisierung des Gebots durch das System, um das Höchstlimit des Bieters widerzuspiegeln.
