Characteristics of Sapphire

But did you know that sapphires come in a variety of colors other than blue, including purple, orange, pink, and yellow?
The mineral name is corundum,Ruby is the same mineralIn fact, all colors except red are classified as sapphires. When it comes to colors close to red, some appraisal institutions may distinguish between ruby and sapphire, making it difficult to draw the line.
Because it is corundum, it has a hardness of 9 on the Mohs scale, making it a perfect gemstone for jewelry. Normally, beautiful color is achieved by heat treatment, but beautiful sapphires can be obtained without this treatment.No heatSapphires are sold in the market as precious stones and are highly valued. The main sources are Myanmar (Burma), Thailand, Sri Lanka, etc. Sapphires come in a variety of colors and shapes, and can be matched with a variety of styles.
Royal blue is considered the highest grade of blue sapphire. It is a special gemstone with a deep, noble blue color and a vivid shine. Usually, as the blue color gets darker, it loses its shine, but royal blue retains its vividness and brilliance. It is also the official color of the United Kingdom.

Cornflower is native to Kashmir and is named after the color of the cornflower flower. Although it is the same blue color, royal blue is a deep color that gives it a noble impression, but cornflower is characterized by a slightly paler and gentler hue. Of course, it is also highly saturated, and only cornflowers with a brilliant color are given the name. Currently, cornflower from Kashmir is rarely produced, and it is quite expensive.

Padparadscha means "lotus flower" in Sinhalese. Because it has a narrow color range, only intermediate shades between orange and pink, it is traded at a high price as a rare stone. This is also determined by color, and whether it will be identified as a padparadscha sapphire will vary depending on the appraisal agency. If the pink is strong, it is a pink sapphire, and if the orange is strong, it is an orange sapphire. This subtle hue gives a calm and elegant impression, and dresses up in a mature style.

Star sapphires have a star effect, where six lines appear when light is shone on them. This star effect is caused by inclusions and is made apparent by the soft, rounded cabochon cut. The production of large star sapphires is becoming less and less, and those with a deep, beautiful body color are highly prized.

Caring for Your Sapphire
To clean, fill a cup with lukewarm water and add a small amount of mild detergent (dishwashing detergent). Then, dip a soft brush (such as a toothbrush with soft bristles) in the detergent and gently tap the stone to clean it. If you scrub, the prongs holding the stone in place may come loose, so it's important to tap the stone. When you're done cleaning, rinse with lukewarm water.
We also recommend using an ultrasonic cleaner to remove any fine dirt.

It looks similar to morganite, but is characterized by its purple-pink color, and even though it is pink, it tends to have a mature, subdued shade.
This gemstone is relatively inclusion-free and is often mined in large crystals, making it a great choice for those looking for larger pink jewelry.
Another attractive feature is its pleochroism, which allows it to show different colors depending on the angle from which it is viewed.
The mineral name is spodumene. Its Japanese name is "spodumene." Among this mineral, the pink one is called kunzite, the green one is called hiddenite, and the yellow one is called triphane.
The main sources of kunzite used in jewelry are Central Asia, including Afghanistan, and Nigeria. Kunzite from Afghanistan and Pakistan is particularly popular because it is vibrant and highly transparent.

Also, storing jewelry in direct sunlight or in a high temperature place for a long period of time may cause it to fade, so be sure to store it individually in a jewelry box at the appropriate temperature.
To clean, fill a cup with lukewarm water and add a small amount of mild detergent (dishwashing detergent). Then, dip a soft brush (such as a toothbrush with soft bristles) in the detergent and gently scrub the stone. If you scrub too hard, the prongs holding the stone in place may come loose, so it's important to scrub gently. Once you've finished scrubbing, rinse the Kunzite with lukewarm water.
