How to choose your favorite ruby? Ruby is smart in selecting color and clarity

02-10-2023

On the premise of nature, experts use 4C to measure the value of gemstones, that is, Color, Clarity and Car-at. Generally, the impact of color on the value of gemstones is 50%, followed by clarity and size, and finally cutting. The order of the 4C value judgment criteria for ruby and diamond is different, but the principle remains the same, that is, the order and proportion are arranged according to the beauty and permanence of the gem and the rarity. As for rubies, not all rubies have collection value. We must choose rubies with good color, large particles, high purity and good fire color. Therefore, we can select ruby from color, clarity, fire color, weight, characteristic observation and certificate.

Choose ruby - color: the more saturated, uniform and bright, the better

The color of ruby is the first sight. The more saturated, uniform and bright the better. Generally speaking, the price of dark and positive ruby must be higher than that of light ruby; The bright price must also be higher than the dark price. Generally, rubies are divided into five grades: dark red, red, medium red, light red and light red. There are many colors of ruby, the best is the dark pure red, the second is the purplish red, the next is the dark pink, purplish red, and the brownish red, and the other is the poor ruby.

Color is the color of a gem in natural light. It is the key to evaluate ruby. The purer and stronger the color, the better the quality. If there are green, black or light colors in the gem, the value of the gem will be affected.

The ruby with pigeon blood red produced in Myanmar is the most precious. Its name is derived from the fact that this red color resembles the extremely red blood of a pigeon in Mogu region. This is a strong color that can almost be called deep red. Pure red contains blue hue, giving people a strong feeling of "burning fire" and "flowing blood".

Cherry red is also famous. It is produced in Sri Lanka and ranks among the top grade rubies. This color is due to the fact that the red tone contains a little purple, which makes the color of the gem equally strong and bright, noble and not vulgar.

In addition, there are also some places in the world where the color of rubies is also extremely beautiful, such as the rubies produced in Mozambique, which are named "Windsor color". Such rubies are bright red with a slight yellow tone, and are also colorful and attractive, making people linger. At present, the price is also extremely expensive in the international market.

Choose Ruby - Clarity: The cleaner the more expensive

In the process of gem formation, it will capture the surrounding minerals and water vapor, and produce bubbles, liquid, solid minerals and other inclusions. Inclusion is also known as "impurity" or "defect". When selecting ruby, of course, the less the content, the cleaner, the more transparent and the higher the value. However, as the saying goes, "ten red and nine cracks" means that there are usually many packages and cracks in the ruby. The ruby with positive color and no internal defects is very rare and expensive.

Generally speaking, rubies can be accepted if they can't see defects with the naked eye. If it is a collection investment, of course, the cleaner the better. However, we can't see the completely transparent and flawless ruby, so we should be vigilant that it is a synthetic ruby.

Diamonds

Each diamond has its contents. The quantity, size, shape and color of its contents will determine the clarity and quality of each diamond. Most of the diamond's contents cannot be identified by the naked eye. The less the contents, the more the light refracts, making it doubly bright. We can use a 10x magnifying glass to find out the difference. The cleanliness classification standards in the United States include: FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, I1, I2, I3. (Note: FL is the best, decreasing in order.)

Flawless

Under a ten-fold mirror, no defects can be detected inside or outside the diamond.

IF (Internally Flawless) has no internal defects

Under a ten-fold magnifying glass, the diamond has no defects on the inside, but small defects on the outside.

VVS1, VVS2 (Very Very Very Slightly Included)

Under a ten-fold magnifying glass, there are tiny defects, such as pin-point size, that are difficult to inspect inside or outside the diamond.

VS1, VS2 (Very Slightly Included) slight defects

Under a ten-fold magnifying glass, there are defects on the inside or outside of the diamond that are difficult to inspect.

SI1 (Slightly Included)

Under a tenfold magnifying glass, some defects can be seen inside and outside the diamond.

Diamonds above "SI1" level are of good quality if the defects are invisible to the naked eye.

SI2 (Slightly Included)

Under a tenfold magnifying glass, it is easy to see defects inside or outside the diamond. Some of these defects can be seen directly with the naked eye.

I1 (Imperfect) is defective

The inner and outer defects of the diamond can be seen directly with the naked eye.

I2 (Imperfect) is defective

The inner and outer defects of the diamond can be seen directly with the naked eye. The content accounts for a quarter of the diamond and affects the brightness of the diamond.

I3 (Imperfect) is defective

You can directly see with the naked eye that there are many obvious defects on the inside and outside of the diamond.
