    This is an excellent video! It's great to see a comprehensive overview of the key factors to consider when choosing a diamond, including cut, color, clarity, and carat weight. I appreciate the clear explanations and the examples provided to help illustrate the different grading scales and how they apply to real diamonds. This video is a great resource for anyone looking to purchase a diamond and I will definitely refer back to it in the future. Thank you for sharing!

    You have to be careful buying over seas. Some times they'll stamp the inside of the ring S925 & after wearing it a short time your finger turns green. Accupple coats of clear nail polish works.
    Ck with a jeweler you trust to see if the stones are real at least. If real, when have the cash have the stones reset. 1st ck to see if the stones have numbers, & if they do ck the numbers again before finel payment & walking out the store, just to be sure.

    If we compare these two precious stones, then we will see that the value of a diamond is much higher. So for example for a one-carat diamond, you should pay 1420 dollars to 17000 dollars. For this amount, you could get about two carats of moissanite, and possibly more, which means that the diamond is worth more. - Tycoonstory Media

      The gospel (good news) for lost souls:
      Jesus Christ is the only way to Heaven, there is no other way! You only have to believe in what Jesus Christ did for you on the cross at Calvary, He died for the sins of the whole world and that's including you, so why not live for Him?
      It's all about Jesus Christ's precious blood - Romans 3:25 - Whom God hath set forth to be a propitiation through faith in His blood, to declare His righteousness for the remission of sins that are past, through the forbearance of God;
      1 Corinthians 15:1-4, saves lost souls when you truly believe from your heart. Jesus Christ paid the death penalty in our stead and nailed it to the cross. Romans 6:23 - For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
      Ephesians 1:13, saved and sealed with the Holy Spirit of promise.
      Heaven and Hell are real, literal places, there is nothing in-between. Choose your eternal destination wisely for your soul.
      Time is running out.

      If you or your jeweller has a GIA client account, he can send it to them to ask for a new expertise after it has been treated or re-cut, in that case you'll have to send the paperwork of the alterations along with the stone. Mind you, sometimes it can be graded lower or higher. If you don't agree with their findings, well...that is just very unfortunate.

      Cut. I think of it like a prism just with way more sides. 😂 light hits the stone and reflects off each surface

    How can you tell a lab grown diamond from a natural one?

      Hi Shaun, You will not be able to see the difference between a natural and a synthetic diamond just by looking at it. At GIA, the lab uses a screening device which indicates if a diamond is natural or needs further testing. If advanced testing is required, methods can include, but are not limited to, photoluminescence (PL) spectroscopy, Fourier-transform infrared (FTIR) absorption spectroscopy, Raman PL spectroscopy, and fluorescence imaging techniques.

      CZ's have more fire, while diamonds have more white light.

    Carat and clarity are far more expensive than color and cut
