How are Lab Grown HPHT Diamond Made?

Lab Grown HPHT Diamonds are made in a process called chemical vapour deposition (HPHT). During this process, the carbon atoms that make up a diamond are transported from a gas source and deposited onto a diamond seed crystal. The layers that result from this process are so thin (approximately 2 - 3 microns or 1/100th the thickness of a human hair) that they are invisible to the naked eye. The round brilliant is the most popular shape because it has the highest light return, giving a superior level of sparkle and fire without additional cutting.

What are the 4CS and which C is most Important?

The 4Cs of Diamonds are cut, color, clarity and carat. The primary concern is to make sure each C is as effective as possible. Cut is most important as it directly affects brilliance and fire (sparkle), Color has to do with how white the diamond is or whether it has tints of yellow or brown. The four Cs are all equally important as each one supports another.

How do you determine if a diamond is real?

One of the main reasons is to assure them of its authenticity, quality and value. The first piece of advice I would give them is to have their diamonds certified by an independent gemological lab.

Is a round brilliant cut diamond good?

This is a round brilliant cut diamond. It has 56 facets, which allow maximum amount of light to enter the diamond, giving it a fire and sparkle. This is what makes this cut so beautiful.

Why round brilliant cut is more expensive?

It’s more expensive because it takes longer to produce, and it looks more flashy than other cuts. It’s also cut so that the facets reflect light rays, which makes it sparkle more. Round brilliant is the most popular style in cut diamonds, and that’s why it’s more expensive.
