SRI LANKA-Star Rubies 斯里兰卡红宝星石

Star Rubies are beautiful gemstones that display a six-ray star that seems to glide magically across the surface of the gem when the latter is moved. This six-ray star is caused due to an optical phenomena known as “Asterism“. The term “Asterism” is derived from the Greek word “aster”, which means star, so asterism is commonly referred to as “star” or “star-effect”. In simple words, asterism is a star-shaped light effect across the surface of gems.

紅寶石屬剛玉硬度九,僅次於鑽石的珍貴寶石,這顆纯天然通透的斯里兰卡紅星寶石,沒有二度激燒等優化處理,是可愛高貴的收藏。星光現象的產生,是由於寶石內針狀金紅石內含物, 按照三方晶系的晶形生長.當其切磨成凸面寶石時,可在點光源下看到呈六線的交叉星芒, 星芒會隨著觀看的角度不同而移動,但是如果注意觀察,單條星茫光不論如何移動,星茫光的方向都是一致的,如此可印證此星光是由其內部結構所產生此星石,星光茫清楚,星茫光無斷裂,還有寶石本體的顏色純淨亮麗。

From Wikipedia, the free encyclopedia

Color in gemstones breaks down into three components: hue, saturation, and tone. Hue is most commonly understood as the “color” of the gemstone. Saturation refers to the vividness or brightness or “colorfulness” of the hue, and tone is the lightness to darkness of the hue.[5] Blue sapphire exists in various mixtures of its primary (blue) and secondary hues, various tonal levels (shades) and at various levels of saturation (brightness).

Blue sapphires are evaluated based upon the purity of their primary hue. Purple, violet, and green are the most common secondary hues found in blue sapphires.[6] Violet and purple can contribute to the overall beauty of the color, while green is considered to be distinctly negative. Blue sapphires with up to 15% violet or purple are generally said to be of fine quality. Blue sapphires with any amount of green as a secondary hue are not considered to be fine quality. Gray is the normal saturation modifier or mask found in blue sapphires. Gray reduces the saturation or brightness of the hue and therefore has a distinctly negative effect.[6]

The color of fine blue sapphires can be described as a vivid medium dark violet to purplish blue where the primary blue hue is at least 85% and the secondary hue no more than 15% without the least admixture of a green secondary hue or a gray mask.[5]
