GIA's color-grading scale for diamonds is the industry standard. The scale begins with the letter D, representing colorless, and continues with increasing presence of color to the letter Z, or light yellow or brown.

Cubic zirconia is a manmade mineral made of zirconium dioxide. CZs can appear to be very like diamonds, but they have very different mineral structures. Cubic zirconias have been found in nature in small amounts, but the vast majority used in the jewelry are man-made in a lab.
Most other letter markings indicate that a piece is gold-plated or gold-filled. Gold-plated pieces may be marked 'GP,' 'GE,' or 'HGE. ' 'GP' or 'GE' means the piece is electroplated with a thin layer of gold; '18K GP' would indicate a piece plated with 18 karat gold.

Cubic zirconia is very inexpensive, since it's synthetic and mass-produced. A cut and polished one carat cubic zirconia stone will cost $20 and a similar two carat stone will cost about $30.
If you're wondering if cubic zirconia is good, then the answer is yes. It is strong, durable, looks great, and is high quality. It is excellent value for money.
No, it's not. It is a diamond simulant, meaning it's created to look like a diamond but it doesn't have the same chemical properties as a diamond (like a lab-grown diamond would). "Cubic zirconia is a diamond simulant that is created solely as a diamond alternative," Wegman adds.
Where can I find my hallmark? The hallmark is normally stamped inside an engagement or wedding ring, with pendants by the bail and with chains and bracelets they are usually found by the clasp. The hallmark consists of 3 compulsory marks together with a 4th often-optional marking.
The term “vintage” has a broad definition in fashion and jewelry. In general, items must be at least 20 years old to be considered vintage. Because jewelry eras tend to last longer and evolve more slowly than other fashion, décor, and style, however, most vintage pieces tend to be at least 50 years old.
Rings, especially wedding rings, have become symbols of love and everlasting love because of the circle's cyclical and eternal character. If you give each other wedding bands or exchange engagement rings, you are symbolically vowing that you will love and be devoted to one another for the rest of your lives together.

In this case the letter 'z' (2) indicates it was assayed in 1874. The date letter changes every year so you can precisely date the year it was made. The maker's mark (1) shows that it was made by Robert Thornton.
What does Z 925 mean on jewelry? It shows that the piece of sterling silver is 92.5 % pure silver and 7.5 % alloys. That is an acceptable quality of sterling silver. Takedown request | View complete answer on thepeachbox.com.
Cubic zirconia diamonds are often described as “fake” or “simulated” diamonds. The truth is that CZ diamonds are not fake diamonds, but simply another alternative, as they are a gemstone in their own right.
Place the gemstones in a glass of water and watch. If it floats, then it is probably a fake stone. Real diamonds will sink to the bottom of the glass, while cubic zirconia will float to the surface.
You will see that the diamond has white or silvery sparkles only. However, cubic zirconia will give out colourful sparkles such as red, yellow or blue. Another important differentiating feature between these two stones is that a diamond possesses sharp facets, whereas a zirconium does not have sharp facets.
Cubic zirconia is an almost worthless stone which is very rarely set into gold or other valuable metals. Unless the setting itself has a value, cubic zirconia jewelry will not be accepted by any Encino Pawn Shop.
Does Cubic Zirconia Turn Green? The stone itself won't turn green, but if it is set in a cheap metal like copper, the metal can turn your skin green.
Over time, cubic zirconia jewelry pieces begin to lose their sparkle. While it may take some work to restore the sparkle, the shine and beauty restored to your pieces is well worth the effort.
Gold is element 79 and its symbol is Au.
You can also fill a cup or glass with white vinegar, and drop your gold in it, let it soak for 5-8 minutes, take it out and rinse with water. If the metal has changed its color even slightly, then the gold is not pure but if it keeps shining, then the gold is pure.
An acid test can reveal the karat of solid gold jewelry, but it can also show whether jewelry is solid gold or gold-plated. With an acid test, a small sample of the jewelry is removed and exposed to acid to induce a color change. The resulting colors indicate which type of metal the jewelry is made of.
