Thank you for your continued patronage.
This time, we will explain what "zirconia" is, which VALEGIO also carries in large quantities!
[What is zirconia?]
Zirconia is made up of yttrium oxide, calcium oxide, and magnesium oxide.
It was crystallized by adding etc.
It is called stabilized zirconia or cubic zirconia.
Artificial stone developed for decorative purposes
It is defined as follows:
In addition, because it is transparent and has a high refractive index similar to that of diamonds , it is called imitation diamond or artificial diamond , and is often used in jewelry, making it a very popular material.
What makes it different from diamonds?
[Differences in production areas]
Diamonds are mined in South Africa, India, Brazil, Russia, etc., while zirconia can be artificially created. It is inevitable that the value of diamonds and zirconia differs depending on the limited supply.
[Colors of Brilliance]
In comparison, zirconia has a stronger iridescent shine. In terms of the color of the light it emits, it is said that diamonds tend to emit white and blue light, while zirconia emits a reddish light.
[Price difference]
As a reference price, zirconia necklaces are around 2,000-15,000 yen, and diamond necklaces are around 10,000-500,000 yen.
【hardness】
On the Mohs hardness scale, zirconia is 8 to 8.5 (hard enough), while diamond is 10 (the hardest in the world).
This is the difference it makes!!
You won't notice the difference in appearance unless you look really closely, so why not try incorporating zirconia into your everyday accessories?
VALEGIO also carries many zirconia products, so please come and take a look.
