What is the best color of sapphire? Is it cornflower blue, or royal blue? According to the current market, cornflowers are much rarer, with higher status and higher prices. But in fact, these two colors have different styles and cannot be generalized.
Royal Blue is a classic style of sapphires. This color is very strong, deep, noble and elegant, making it a favorite of many nobles.
The royal blue gemstone is rich in producing areas, with output in Myanmar, Sri Lanka and Africa. Among them, Burma produces the best and most representative.
Due to the continuous output, Royal Blue's market supply is also stable. Therefore, in the market position will be slightly inferior to the daisy blue.
Cornflower is the national flower of Germany, and the cornflower sapphire has a thick, purplish blue with a sinuous purple color. The key is a velvety unique texture and appearance. This special texture is derived from some tiny filamentous inclusions distributed inside the gemstone. In general faceted gemstones, because only the light on the surface of the gemstone and the internal facet is reflected, it is inevitable that the gloss is "hard" and there will be light leakage and darkening. These filamentous inclusions inside the cornflower sapphire are good for diffuse reflection of light. A soft velvety texture is formed, and the color is full and it is not easy to leak light.
According to truly strict standards, cornflower sapphire is only produced in the Kashmir region of India, at the northwestern tip of the Himalayas. It is extremely cold all year round, the weather and geological conditions are extremely harsh, and mining is extremely difficult.
Cornflower sapphire began mining in the mid-19th century and has been completely stopped since the early 20th century. Rare production makes every gem precious. Therefore, the top cornflower sapphire produced in Kashmir is also known as Kashmiri sapphire.
In the 2009 Christie's Autumn Auction in Hong Kong, a Kashmir Sapphire Ring weighing approximately 16.65 carats was sold for $2.4 million, equivalent to $144,100 per carat.
There are also significant differences in the attitudes of different appraisers in the treatment of cornflower blue and royal blue.
GRS has a low standard for cornflowers for some time. Many of them have a velvety texture, and many of them can get the rating of cornflowers. At one time, cornflowers are flooded. Later, after adjustment, it divided the cornflower blue into LightCornflower and IntenseCornflower. Later, the evaluation criteria were tightened. It’s not so easy to get a rating for cornflowers today.
For the SSEF and Gubelin and other well-known identification agencies, more than 99% of the sapphire is sent for inspection, the color is "blue", and only the remaining one can get Royal Blue or Cornflower Blue. Among them, only a very small part of the CornFlower rating can be obtained.
As for which color sapphire is better, there is no complete conclusion. The top royal blue is not inferior to the cornflower. And if the gem's clarity and other parameters drag the legs, cornflowers may also cost thousands of dollars a carat. In addition, due to personal differences, many people think that cornflowers are soft, full, bright and bright, but some people think that the royal blue is steady and deep, not comparable to cornflowers. Therefore, in the case of much less possession, although the overall value of the cornflower sapphire is now high, it cannot be said that the royal blue is not comparable to the cornflower blue.
