The 4'C of a Diamond

Diamond Cut

It's important to note that a diamond's cut grade plays a crucial role in determining its overall appearance and value.

Shop Natural Diamonds

Diamond Cut refers to the quality of a diamond's facets, symmetry, and reflective qualities. This factor is critical in determining a diamond's overall brilliance and beauty. The Gemological Institute of America (GIA) sets the standard for grading diamond cuts and uses a scale that ranges from Excellent to Poor. To determine the cut grade, the GIA assesses the diamond's proportions, symmetry, and the quality of its polish, taking into consideration how well these elements interact with light to create a beautiful and sparkling appearance. In short, the better the cut, the more radiant and stunning the diamond will appear.

Diamond Cut Grading

Diamonds that are Cut Very Good

"Very Good" Cut: A diamond with a Very Good Cut grade still has excellent proportions and symmetry, but with slightly less brilliance and fire compared to an Excellent Cut diamond.

Diamond Shape

When choosing a diamond shape, it is important to consider both your personal style preferences and the diamond's cut, color, and clarity, as these factors can impact the diamond's overall appearance and value. Whether you prefer a classic round shape or a more unique, fancy shaped diamond, the shape you choose will be a reflection of your individual taste and style.

Diamond shape refers to the external geometric appearance of a diamond. The shape of a diamond can greatly impact its overall appearance, and there are many shapes to choose from, including round, princess, emerald, pear, marquise, oval, cushion, and more. The Gemological Institute of America (GIA) is a standard used to determine the shape of a diamond. The GIA is an internationally recognized authority on diamonds and gemstones, and their standards are widely accepted in the industry. The GIA determines the shape of a diamond by examining its external geometry, ensuring that it conforms to the specific shape criteria established for each shape.

Diamonds & Diamond Alternatives

Diamonds have been treasured for their beauty and durability for centuries. While natural diamonds are formed in the Earth's mantle over billions of years, lab-grown diamonds are created in a laboratory using advanced technology. They both have the same chemical and physical properties, but lab-grown diamonds are typically less expensive and more sustainable than their natural counterparts. Moissanite, on the other hand, is a lab created and also used as a diamond alternative. It has a similar appearance to diamonds and is often less expensive, but it is not as durable and has a slightly different color and refractive index. When choosing a diamond or a diamond alternative, it's important to consider your personal preferences and budget, as well as the benefits and differences of each option.

Q: What is Natural Diamonds?

A: Natural diamonds are a type of carbon mineral that are naturally occurring and formed in the Earth's mantle over millions of years. They are prized for their exceptional hardness, brilliance, and sparkling luster, and are widely used in jewelry, industrial tools, and other applications. Natural diamonds are found in volcanic pipes and kimberlite deposits and are extracted through mining.

Q: What is Lab Grown Diamonds?

A: Lab-grown diamonds are diamonds that are manufactured in a laboratory setting, rather than being naturally formed in the Earth's mantle. They are created using either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods, which mimic the natural process of diamond formation. Lab-grown diamonds are chemically, physically, and optically similar to natural diamonds and are often used in jewelry, industrial applications, and for scientific purposes. They are typically cheaper than natural diamonds and can be produced in large quantities.

Q: What is Moissanite?

A: Moissanite is a type of artificial crystal that is similar in appearance to diamond and is often used as a diamond simulant in jewelry. It is made using a process called chemical vapor deposition, which involves depositing a thin layer of silicon carbide onto a substrate. Moissanite is known for its brilliance, fire, and durability, and is often used as a cost-effective alternative to diamond. Unlike diamonds, moissanite is not as hard, but it is still a popular choice for those who want the look of diamond without the high cost.
