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.

Cuando se realiza una oferta, este es el monto máximo que una persona está dispuesta a ofertar por el producto. Nuestro sistema ofertará automáticamente en nombre del postor y aumentará la oferta de manera gradual hasta el máximo para mantener su posición como el mejor postor.
Cuando hay un ícono que indica "Oferta automática", significa que nuestro sistema está realizando ofertas de forma activa para el postor en función de su oferta máxima. Esto puede parecer como si los postores estuvieran pujando más que ellos mismos, pero es simplemente el resultado de que el sistema actualiza la oferta para reflejar el límite máximo del postor.
