In addition to noble blue sapphire there are many different types of coloring these wonderful minerals. Corundum, featuring pink, yellow, purple, green, purple and lilac tones, are called fancy sapphires. Instances pink, lilac and purple the colors are truly unique and are less common blue and yellow varieties of sapphire.
Pink sapphires are a variety of the mineral corundum, which also includes ruby. Like rubies, sapphires are graded according to the "Four Cs": carat weight, cut, color, and clarity.
When it comes to color, pink sapphires can range from pale pink to deep pink, with some even approaching red. The most valuable pink sapphires are those with a strong, saturated color that is evenly distributed throughout the stone. The most sought-after shade is a medium-dark pink, sometimes referred to as "pigeon's blood" red.
It is important to note that natural pink sapphires are relatively rare, and many pink sapphires on the market have been treated or heated to enhance their color. If you are considering purchasing a pink sapphire, make sure to ask the seller about any treatments that may have been performed on the stone.
Pink sapphires, like many other gemstones, can be treated to enhance their color and clarity. Some of the most common treatments used on pink sapphires include:
Heating: This is one of the most common treatments used on sapphires of all colors. Heating can be used to improve the color of a pink sapphire, making it more intense and vibrant. It can also be used to remove inclusions and improve clarity. This treatment is considered permanent, and does not change the physical or chemical properties of the stone.
Diffusion: This is a treatment where colorless corundum is treated with beryllium which diffuses into the surface, creating a thin layer of color. This treatment makes the sapphire look as if it has a more intense color than it actually does.
Here is a general guide to pink sapphire weights and their approximate measurements in carats:
up to 0.5 ct: Small, suitable for accent stones or small earrings
0.50-2.00 ct: Medium, suitable for small rings or pendants
2.00-4.00 ct: Large, suitable for rings or larger pendants
4.00 ct and above: Extremely large, suitable for statement rings or large pendants
It's important to note that this is a rough guide and the actual size may vary depending on the cut, shape and measurements of the stone. Also, some shapes like cushion or pear might look larger than the round shape with the same carat weight.
Some of the most notable mining locations for pink sapphires include:
The price of pink shade sapphires increases as their brightness increases, which is typical of all fancy sapphires. Natural pink sapphires of varying degrees of color saturation and size can be bought on the market for $900-3000 per carat. The price for refined pink sapphires is lower, but if the stone is large, clean, and bright, then the price will not differ dramatically from non-treated pink stones. It is important to note that pure pink sapphires with spectacular pink hues are very rare, so a 3-4-carat sample is already considered large.
Vivid red-pink stones are often valued even above their blue, high-quality gem-quality counterparts. The price of untreated large specimens of this hue reaches tens of thousands of dollars for one carat.
