FAQs

Lab-grown diamonds are produced in a laboratory by simulating the extreme conditions in which natural diamonds form. A diamond ‘seed’ is set in carbon-rich conditions inside a sophisticated growth chamber. Using our exclusive growth technique, the seed develops into a rough diamond. The rough diamond is then planned, laser cut, polished & finished just like a mined diamond is. Common two methods include high pressure and high temperature (HPHT), which converts graphite into diamond through high pressure and temperature, and chemical vapor deposition (CVD), which forms diamond crystals by depositing carbon atoms layer by layer by decomposing a carbon source gas in a vacuum environment. These methods can precisely control the growth process of diamonds, thereby producing high-quality, impurity-free diamonds. They embody the years of hard work and wisdom of countless scientific researchers and have promoted major changes in the diamond industry.

Yes. Lab grown diamonds have the same physical, chemical, and optical characteristics as natural diamonds, as well as the same fire, scintillation, and sparkle. They are real diamonds. Lab grown diamonds are nearly impossible to differentiate from natural diamonds with the naked eye.The main differences lie in their origin and environmental impact. Compared with natural diamonds that require large-scale mining, laboratory-created diamonds are generally cheaper, have less impact on the environment, and are more in line with the concept of human sustainable development.

Lab-grown diamonds are diamonds artificially grown in a laboratory. Their chemical composition and structure are exactly the same as natural diamonds, and they are also impeccably hard and bright. The lab-grown diamonds are real diamonds, and the price is only 30-50% of natural diamonds. Undoubtedly, They are an environmentally friendly alternative to natural diamonds. Moissanite is a natural synthetic gemstone that is highly regarded for its outstanding fire. Its Mohs hardness is 9.25, second only to diamond, and it is very durable. But it is not a real diamond. Its structure and composition are very different from natural diamonds. In fact, moissanite has more dazzling fire than diamonds and can emit colorful brilliance in various lighting conditions. Whether you choose lab-grown diamonds or moissanite, they both have more environmental and ethical advantages over natural diamonds. Lab-grown diamonds avoid the environmental damage and labor exploitation caused by mining, while moissanite reduces the demand for natural resources through an efficient synthetic process.

Yes. Because our lab grown diamonds are man-made in our controlled laboratory setting, they are 100% conflict-free and do not require mining tons of earth to find them. All local labor laws are followed, including child labor laws, and the creation of our lab grown diamonds is free from funding violence, warlords, corrupt governments, or other human rights abuses.

K gold combines the best of both worlds—purity and strength. It is less prone to scratching and bending compared to pure gold (24K), making it ideal for everyday wear. Additionally, K gold’s versatility in color (yellow, white, and rose) allows it to complement various skin tones and styles, offering timeless beauty that aligns with both modern and traditional tastes.

 First of all, K gold is an alloy formed by adding a small amount of other metals to gold in a certain proportion. International standards refer to theoretically 100% pure gold as 24K gold. The gold content of 1K is approximately 4.166%, 9k is 37.5%, 14k is 58.5%, and 18k is 75%. 24k gold is theoretically pure gold, that is, the gold content is 100%. .
Secondly, K gold has high hardness, low toughness, high brightness, is not easy to deform, is not easy to wear, can fix diamonds more firmly, and is relatively cheap (compared to platinum). However, pure gold is too soft and complex designs cannot be made. The labor cost of K gold is relatively high. After recycling the molten gold, only 50% is left, and only 50% is left after the round trip loss. Therefore, from an investment perspective, the investment value of pure gold is greater than that of K gold. But as an excellent piece of jewelry, K gold is the best choice.
At last, The process requirements of K gold are higher than that of pure gold, and it needs to go through more than ten processes (briquetting, wire drawing, heat treatment, electroplating, etc.). Therefore, the workmanship is meticulous, the appearance is fresh, the surface is smooth, and the inner light is strong. The processing of pure gold is relatively simple and can be processed by ordinary hand workshops; while the processing of K gold is difficult and often requires many large machines and precision instruments. The processing personnel are also more professional, which increases the cost and management expenses. In addition, the ratio of raw materials is also a very important link in K gold, while the requirements for pure gold are not so high.

Yes. We have a legal obligation per the National Stamping Act to stamp silver and gold jewelry, and we follow the guidelines for stamping as set forth by the Federal Trade Commission. These markings, or stamps, are required to show the quality of the metal. For example, if the item is made of 14 karat gold, the stamp will show 585(This stamp indicates that the gold content in the jewelry is 58.5%). If you do not see the stamp with the naked eye, we recommend looking through a magnifier or jeweler’s loupe.
