Lab Grown Diamond Customization

There are real diamonds. They have the same optical, chemical, thermal, and physical features

What are Lab-Grown Diamonds?

Lab-grown diamonds are chemically, physically, and optically identical to natural diamonds. They are created using two primary methods:

  1. High Pressure High Temperature (HPHT): Mimics the natural conditions under which diamonds form. Carbon is subjected to extremely high pressure and temperature in a lab to crystallize into diamond form.
  2. Chemical Vapor Deposition (CVD): Involves placing a small diamond seed in a chamber and using a gas mixture to deposit carbon atoms onto the seed, allowing it to grow into a diamond.
Benefits of Lab-Grown Diamonds
  1. Ethical Considerations: Lab-grown diamonds avoid the ethical issues associated with conflict diamonds (also known as blood diamonds), which are mined in war zones and used to fund armed conflicts.
  2. Environmental Impact: They generally have a lower environmental impact compared to traditional diamond mining, which can involve significant ecological disruption.
  3. Cost-Effectiveness: Lab-grown diamonds are often less expensive than natural diamonds of the same size and quality, making them a more budget-friendly option.
  4. Customization: Easier to produce diamonds with specific characteristics, such as color and clarity, allowing for more customization options.

Lab grown diamonds are not fakes. They're not zirconia. They have all the same phyiscal and chemical properties of a minded diamonds.

Lab grown diamonds are best value for money, lab grown diamonds are also much more affordable than mined diamonds of comparable size and quality.

Lab grown diamonds are same as the nature diamonds, the only real way to differentiate between the two is by utilising specialised heavy-duty equipment to quantify the level of impurities found in natural diamonds that area absent in lab grown diamonds.

Learn About Diamond shapes

Diamonds are formed into many shapes. Each shape is unique and has a different look and effect. Here are some of the most popular diamond shapes:

Round Brilliant Shape

The Round Brilliant Shape is the most popular of all the diamond shapes. The Round Brilliant is cut with 58 facets allowing the light to be reflected throughout the stone. Due to the way it is cut, it sparkles more than any of the other diamonds. Inclusions are not as visible in the Round Brilliant Shape like they are with some of the other stones.

Oval Shape

Oval Shaped Diamonds are quite brilliant. However, like the Pear Shaped Diamonds, caution is needed when purchasing to make sure that there are no “bow-ties” (grey triangular reflection) inside the stone. Small bow-ties are fine, but larger bow-ties will cause a large grey patch in the stone, detracting its sparkle. It is important to look at the length-to-width ratio of the oval shape, making sure that the stone is not too skinny and long or too short and wide.

Pear Shape

Pear Shape Diamonds are quite brilliant. However, caution is needed when purchasing to make sure that there are no “bow-ties” (grey triangular reflections) inside the stone. Small bow-ties are fine, but larger bow-ties will cause a large grey patch in the stone, detracting its sparkle. It is important to look at the length-to-width ratio of the Pear Shape Diamond, as a stone that is too skinny and long or a stone that is too short and wide would not look so good.

Princess Shape

The Princess Shape Diamond is a square-cut diamond. Due to the corners being at 90 degrees, the corners must be protected by decent claws when set into a ring. Princess Shape Diamonds are well-priced since they do not have much wastage when cut from a rough diamond.
