1, cutting work

Ruby is illuminated by a light source, and the color on the front of the ruby is called fire, like a string of jumping small flames, which is a comprehensive embodiment of the quality of ruby. For ruby, the more cutting layers, the better the fire color. Fire color is an important factor to determine the quality of ruby, and a high-quality ruby fire color accounts for more than 55% of the total crown.

Step 2 be clear

The term "ten Hong Jiu cracks" is the most commonly described term for ruby purity, which means that nine out of ten rubies have cracks or inclusions, which is also a general portrayal of ruby purity. Completely flawless rubies are very rare and the price is staggering. Colored gems, like diamonds, does not need a magnifying glass of ten times to ask for cracks and flaws, especially rubies.

3. Weight

Like all gems, size is an important factor affecting the price! For rubies, on the premise of ensuring quality, one carat is an entry-level choice, two to three carats are acceptable, and more than five carats is a relatively good collection choice. Up to 8 carats of high-quality goods, which are auction house-level. Of course, the auction house always has several ruby lots every year, and the price of high-quality rubies of about five carats is also very high.

However, if everything is based on quality and budget constraints are considered, it is important to balance the relationship between scale and quality. After all, for all jewelry, the price of 2 carats is not equal to the simple addition of the two prices 1 carat, and there will be a geometric leap, so the choice of how large a gem should be considered comprehensively.

Features—

Ruby is one of the precious varieties in jewelry. Ruby is bright in color, and under the illumination of light source, it can reflect beautiful and moving six-ray starlight, commonly known as six lines, which is caused by the special crystal structure of ruby and its unique optical phenomenon. Ruby is transparent, translucent and opaque, and its colors are water red, pink, pigeon blood red and rose red.

Because big gems are very rare, rubies with larger particles are generally fake. There are two kinds of fake rubies: the first is to pass the low-grade rubies off as rubies, and all fake rubies do not have the unique color of rubies. The second is artificial ruby.

Artificial ruby is very similar to natural ruby in terms of specific gravity, hardness and color. Intuitively, artificial rubies have uniform texture, no natural impurities, even and positive color, often large particles and lack naturalness.
