Something About Rose Cut:
The rose cut (also called the rosette cut) for diamonds was invented in the 17th century and its used continued until the 18th century. The rose cut has a flat base and triangular facets (usually 24).
An old diamond or gemstone cutting style with a flat base and usually two horizontal rows of facets rising to a point. Sometimes called a Dutch rose cut, it may have as many as 24 facets.
An early style of cutting that is thought to have originated in India and to have been brought to Europe by the Venetians.
A style of diamond cutting or other transparent gemstone that produces a gem with a flat base and triangular facets that rise to form a dome.
This style of cut has been in use since the 16th century. These are, like the step cuts, an older cut of diamond. Developed prior to the use of electric lighting, rose cuts fell out of favor in the early 20th century, due to their lack of brilliance.
What is Cubic Zirconia?
A: Cubic Zirconia (or CZ) is zirconium oxide (ZrO2 ), is widely synthesized for use as a diamond simulant and it is a lab made created stone with a specific gravity of between 5.6-6.00 and at about 8.5 hardness on Mohs scale, which is harder than most natural gems. Its refractive index is high at 2.15 - 2.18 (B-G interval) and its luster is very good. Its dispersion is very high at 0.058 - 0.066, exceeding that of diamond (0.044). Cubic Zirconia Gemstones is the best stimulant for the Real diamond, it's beautiful and brilliant for the Jewelry designs.
How Loose Cubic Zirconia Quality is Determined?
A: There are four main factors that help determine the quality or grade of cubic zirconia. These are carat (or carat weight), clarity, color, and cut. CZ stones are imitation diamonds or simulants and are measured in carat weight. Loose cubic zirconia stones are always heavier than real diamonds. This is because the materials that are used to create the stones are denser.
Though loose cubic zirconia stones are generally colorless, many shades of colors can be added using trace elements during the manufacturing process. These colors might include lavender, peridot, pink, violet, champagne, aqua, citrine yellow, and others. Typically, transparent cubic zirconia will be the more valuable, high-end diamond imitation. Colored CZ stones are valued according to the rarity, evenness, and tone of their colors.
Clarity, or clearness, of loose cubic zirconia is also a quality factor. The manufacturing process can sometimes cloud a stone, making visible imperfections. Just as with genuine diamonds, the clearer the stone is, the greater the value.
The cut is also very important in determining quality for loose cubic zirconia stones. Just as with diamonds, the cut reveals the stone's beauty through every facet. The facets must be even and precise to create just the right appearance. Also as with diamonds, the skill of the stone cutter makes all the difference. Stone cutters do much more than cut. They analyze the stone carefully to determine how much of the stone should be cut off to give proper clarity. Then, they take many steps to perfect their cut without taking away from the stone. Though the Brilliant cut is the standard, there are other popular cuts such as the Trillion, Princess, and Radiant cuts. There are also a variety of shapes to give each stone its own unique personality.
