未処理および非加熱ルビーについて

Ruby has been prized for centuries for its rich red hue and vitreous (glass-like) luster. Ruby is a red variety of corundum that gets its color from chromium. The word "corundum" comes from the Tamil 'kurundam', meaning 'ruby sapphire', while the term 'ruby' is derived from 'ruber', the Latin word for 'red'. In ancient Sanskrit, ruby is called 'ratnaraj', which translates as 'king of precious stones'. The traditional sources for fine rubies are typically Burma and Thailand, but today many affordable rubies are coming from various regions of Africa, including Tanzania, Sir Lanka (Ceylon), Mozambique and Madagascar. Because of ruby's excellent hardness, rich color and silky luster, fine quality ruby is classed as one of the so-called "precious four" gemstones, along with diamond, emerald and sapphire. Ruby is the official birthstone for the month of July, and it is the gem used to honor the 15th and 40th year anniversaries.

Almost all ruby today is enhanced by routine heat treatment, which improves not only the color, but also its clarity. Many rubies on the market today may have been fracture-filled, which offers an affordable ruby choice for those who would not normally be able to afford an unheated ruby. Rubies can range in color from pinkish-red to orangey-red, and from violet-purplish-red to brownish-red. Most ruby experts would agree that a stone with medium to medium-dark color tone is considered a very good color for ruby gemstones. Untreated and unheated natural ruby is very rare, since almost all material is heavily fractured and included prior to processing. Gem testing can indicate whether a ruby has been heated usually though the presence of silky rutile inclusions, which is an indicator used to test for unheated sapphire. Despite all of the various gem treatments that ruby is often subjected to, unheated ruby can be found though it is not always easy to source. Reputable gemstone sellers and dealers should always declare any treatment or enhancement, especially for gem types such as ruby and sapphire, where treatment can impact value tremendously.

I make wire wrapped pendants for birthday presents, and always feature a birthstone as the base for the project. GemSelect has a wide variety of shape/size pieces to fit any budget. A detailed description of each individual stone is perfect for those searching for particular stones for their application, and information on stone treatments and the like are phenomenal.

I love this online site. I can browse and select pieces at my leisure - on my schedule. The gemstones are reasonably priced and appear to be quality for the price.
