GemSelect Newsletter - Cornflower BlueKashmir & Ceylon Blue Sapphire
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 Colored Stones Back to Top
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".

Cornflower Blue Gem Descriptions Back to Top
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".

Other Blue Gemstones Back to Top
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. 
Blue Gemstones - Tanzanite, Sapphire, Kyanite & Blue Topaz
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.

Customer Questions Back to Top
Every month we answer questions of general interest from our customers. Please feel free to send your questions or suggestions to our support team at help@gemselect.com! Question
I want buy a sapphire cabochon and use it for a men's ring, what size would you recommend?
Answer
The perfect size should be approximately 15 x 10mm. The length may range from 14-16mm and the width from 10-12mm. Keep in mind for very small hands it will look too big and the size should be more like in the range of 12 x 10mm.
Question
I just found a beautiful fancy cabochon in your shop, can you recut it slightly so it will fit my existing silver pendant?
Answer
Most of the cabochon gems can be recut without any difficulties. Doublets and triplets like Opal Doublet or Ammolite cannot be recut since it would destroy the created layer structure. Please ask us before buying so we can talk to our gem-cutters at first to confirm that it can be recut.
