Man-made diamonds: This is a common term used for synthetic diamonds that are not of natural origin. Created by human science. They are used both in jewelry and in industry. These diamonds can have various structures, but their features are extremely similar to those of natural diamonds.

The pioneer among lab-created stones was synthetic ruby, crafted in 1892. Today, there is almost every jewelry stone having its lab-created analog.

Lab-Grown Oval Diamonds: Lab-grown oval diamonds look splendid due to their extra clarity and high-quality coloring. They can be the biggest size, decorating rings and pendants. The oval shape and 56 standard facets make the surface of a gemstone visually bigger than in other cuts.

Lab-Grown Pear Diamonds: The pear cut is an original option, combining the best features of two cuts: marquise and round. Due to their perfect proportions, diamonds with a pear cut have the highest scintillation level among other cuts due to the position of their 58 facets.

Lab-Grown Radiant diamonds: This is a rectangle-shaped cut with 70 facets as a standard. It has truncated corners, and it combines both emerald-cut and round-cut features. This kind of cut looks good as a solitaire on an engagement ring.

Lab-Grown Cushion Diamonds: This type of diamond cut resembles a pad. It has truncated corners, and it could be either a more rounded shape or a more rectangular shape. It is the best choice for fantasy-colored diamonds, as it highlights the intensity of unusual shades.

Glossary of Moissanite Jewelry

Moissanite: Moissanite is a lab-created gem, similar to a diamond in its features. Its mineral composition differs from that of lab diamonds or natural diamonds, as the basis of moissanite is not carbon but carborundum.

Moissanite Engagement Rings: These rings are only gaining popularity. They look like natural diamond rings, but moissanites have even more sparkles when light hits them.

Glossary 4Cs

Carat Weight: Carat is an international measure of weight for jewelry stones. It is 0.2 grams, or 0.007 oz. For natural diamonds, a weight of 6 carats or more is a rarity of great value. The stone of 2 carats of natural origin costs more than 2 similar stones of 1 carat. For lab-created diamonds, the number of carats is always higher than for natural gems of similar size and cut.

Clarity Grade: Diamonds without visible defects (scratches, marks, minerals, and other small characteristics that reduce the quality of diamonds) are more valuable. However, most of the inclusions are not visible without 10x magnification. The grading of clarity is based on the location, size, type, and number of defects found in the diamond. It is graded from 1 to 7, with 1 referring to gemstones having fewer than three inclusions visible only with 45x magnification.

Color Distribution: The color distribution of diamonds includes various shades of white and yellow. Its categorization is measured by marks from D to Z. The D-mark refers to the clearest, almost colorless diamonds, without any inclusion of yellow. Z refers to the lowest quality of diamond coloring.

Dispersion: Dispersion is the number of colorful splashes appearing on the diamond's surface when the light hits it. The higher the dispersion, the bigger the number of splashes. For diamonds, the dispersion level is merely 0.044.

Durability: Each mineral's durability describes its ability to withstand high or low temperatures, pressure, or mechanical impact. Natural diamonds are considered to be among the most durable materials. So do lab-created diamonds.

Fire: This feature reflects color splashes that appear when the light hits the diamond. If they are numerous and bright, enclosing the full rainbow spectrum, the diamond is of good quality.

Four Cs: The four Cs are carats, clarity, color, and cut. These features are the most valuable when evaluating the quality of a gemstone. Due to them, each diamond gets its total price and designation, whether it suits jewelry goals or should be used in the industry.

Inclusion: Naturally mined diamonds are rarely found in clear water. They have some inclusions, such as other minerals or organic parts, that sometimes make their value lower. In lab-grown diamonds, there are no inclusions due to the precise process of their crafting.

Pavilion: Not all facets of a diamond are visible to the eye. But all of them serve their special mission by creating light that sparkles and shines. That is a pavilion facet placed below the girdle that is V-shaped, reflecting light and sending it back through the crown.

Reflection: That is what makes a diamond sparkle. Due to its facets, not all the light that hits the diamond passes through it. Some rays reflect from its sides, creating sparkles that are the most attractive feature of this gemstone.

Diamond's Transparency: This feature applies to the transmission of light provided by a diamond. If the light passes through the gem without interruption, we talk about an excellent degree of transparency. If there are clouds, hazes, or light refraction, the degree may fall to poor.

Loose Diamond Shapes: The shape of a diamond refers to the initial form of a stone when it was grown or mined. Due to the shape, the cut can be chosen. The bigger the diamond is, the more diverse shapes it can take.

Diamond Cut: The cut is a basic parameter included in the famous 4 Cs. It is the number and size of facets carved by a jeweler on the gem's surface. The most popular diamond cuts are marquise, cushion, pear, princess, emerald, and heart.

Scintillation: When talking about diamonds, the specific term scintillation is used. It means the volume of light that is reflected by a gem's facets. It is visible when moving a diamond.

Different Diamonds Shape vs. Cut: Do not mix terms for the "shape" and "cut" of a diamond. The first one refers to the initial shape of the stone and its peculiarities. The cut option refers to the number of facets and reflections that a gem makes.

HPHT and CVD Diamonds Growth Process: Both of these methods are displaying efficiency in growing diamonds in lab conditions. HPHT, which stands for high pressure and high temperature, is based on using pressure and heat to press carbon into the diamond structure. CVD is the method of carbon deposition in the gas phase.
