GemSelect Newsletter - Cornflower Blue
Cornflower blue is a term often used to refer to blue sapphires, particularly desirable are cornflower blue Kashmir or Ceylon sapphires, though nowadays, blue sapphires are sourced from other places, such as Madagascar and Tanzania, but what exactly is this treasured color?
Cornflower blue gets its name from the eponymous European flower which is prized for its medium blue color. The blue pigment from cornflower was reported by the 17th century chemist, Robert Boyle, who also wrote "An Essay About the Origins and Virtues of Gems", detailing sources and uses of gemstones. This blue dye was therefore also known as "Boyles Blue".
When it comes to details, "Cornflower blue" is a description rather than a technical term. The particular shade of blue is somewhat subjective, so it is difficult to determine. This is why "Cornflower blue" will not be seen on official gemstone certificates, but the color will simply be described as "blue".
Since cornflower blue is defined as pure medium blue it cannot be confused with other color trade names like london blue, sky blue, navy blue or other names describing the blue gemstone color.
If you are looking for a pure blue gemstone, it is hard to beat beautiful, cornflower blue sapphire, but there are other, more affordable options available, such as kyanite, blue spinel and color change fluorite. Cornflower blue is beautiful, but it is not the only blue stone in the jewelry box.
