Sapphire Characteristics

サファイアWhen you think of blue, sapphire comes to mind, as it is the most representative blue gemstone and its Japanese name is "soutama."
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 agencies classify them as rubies and sapphires, making it difficult to draw the line.
Because it is corundum, it has a Mohs hardness of 9, making it a perfect gemstone for jewelry. Normally, it is heated to bring out its beautiful color, but beautiful sapphires can be made without this.No heatThey are sold on the market as gemstones and are highly valued. The main production areas 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.
Some sapphires have names, and I'll introduce a few of them.


■ Royal Blue Sapphire
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, the darker the blue, the darker the shine, but royal blue retains its vividness and shine. It is also the official color of the United Kingdom.
ロイヤルブルーサファイア
■ Cornflower Sapphire
Cornflower is native to Kashmir and is named after the color of the cornflower flower. Although it is the same blue color, royal blue has a noble impression because of its deep color, but cornflower is characterized by a slightly lighter and gentler hue. Of course, it is also highly saturated, and only those that shine are given the name. Currently, cornflower from Kashmir is hardly produced, and it is quite expensive.
コーンフラワーサファイア
■ Padparadscha Sapphire
In Sinhala, padparadscha means "lotus flower." It is a rare stone that is traded at a high price because it only has a narrow color range of intermediate colors from orange to pink. This is also determined by the color, and whether it is identified as a padparadscha sapphire depends 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 color gives a calm and elegant impression, and dresses up in a mature way.
パパラチアサファイア
■ Star Sapphire
Star sapphires have a star effect, where six lines appear when light hits them. This star effect is caused by inclusions, and is made apparent by the rounded cabochon cut. The production of large star sapphires is decreasing, and those with a deep, beautiful body color are valuable.

The origin of sapphire

Its name comes from the Latin word "Sapphirus" which means blue. Its Japanese name is "soutama", so it is a gemstone that has a very strong image of blue.


The Sapphire Effect

The stone's word is "Sincere love, compassion, and virtue"
The calming sapphire is a symbol of strong love and loyalty between husband and wife.
It has been believed to stabilize both the mind and body, enhance concentration and intuition, and enable calm judgment.
Sapphires are also sometimes used as something blue when marrying. For this reason, many people, especially overseas, choose sapphires for their engagement rings. Sapphires, which represent sincere love, are also useful in romantic and affectionate matters.
This is the perfect gemstone for those who want to build good relationships and stabilize their emotions.


Caring for your Sapphire

Sapphires are known as the hardest gemstones, with a Mohs hardness of 9. Don't worry about it, use them as much as you like. However, they are softer than diamonds, so try to avoid storing them with other jewelry as much as possible.
When cleaning, fill a cup with lukewarm water and add a small amount of neutral 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 stone, the prongs that hold the stone in place may come loose, so it is important to wash it by tapping it. When you're done washing, rinse it off with lukewarm water.
We also recommend using an ultrasonic cleaner to remove any fine dirt.

Kunzite characteristics

クンツァイトKunzite was designated as the birthstone for July in 2021. It is not well known yet, but it was discovered in a California mine in the early 20th century.New GemsThat's it.
It looks similar to morganite, but it has a distinctive purple-pink color, and even though it is pink, it tends to have a mature and subdued shade.
This gemstone has relatively few inclusions 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 viewing angle.
The mineral name is spodumene. The Japanese name is "lithium pyroxene." Among these minerals, the pink ones are called kunzite, the green ones are called hiddenite, and the yellow ones are called triphane.
The main sources of kunzite used for jewelry are Central Asia, such as Afghanistan, and Nigeria. Kunzite from Afghanistan and Pakistan in particular is popular because it is vivid and highly transparent.


Origin of Kunzite

Kunzite was named after George Frederick Kunz, the scientist who first identified the gemstone when it was discovered in a California mine.


The Effects of Kunzite

The stone's word is "Unconditional Love"
By accepting yourself, it helps you to stabilize your mind. It also brings you pure love without expecting anything in return, makes you feel gentle and calm, and brings out your own individuality by being tolerant and compassionate.
This is the perfect gemstone for those who want to heal a wounded heart or who want to be enveloped in pure, warm energy.


Caring for your Kunzite

It is a relatively hard gemstone with a Mohs hardness of 6.5 to 7.5, but it will break if it comes into contact with another gemstone.
Also, storing jewelry in direct sunlight or in a high temperature location 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.
When cleaning, fill a cup with lukewarm water and add a small amount of neutral 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 stone, the prongs that hold the stone in place may come loose, so it is important to wash it by tapping it. Once you have finished washing, rinse the Kunzite with lukewarm water.
Also, avoid using ultrasonic cleaners.
