    I doubt it they are powerful enough to sweep in and dominate the lab grown market. They have been making lab gowns for a long time already mainly for industrial uses. They will probably roll out lab growns on the market for cheaper than anyone else can and then market them as inferior to naturals. People will swallow it. You are never going to have a ticket out of having to spend 10-20k on and engagement ring either way i'll tell you that for free.

    I don't think the word synthetic should be put under a bad light. They are synthetic diamonds. They are made by a synthesis and also are not natural. that being said they are exactly the same as natural diamonds.. just the origin is different.

    In gemmology, synthetic means the same as natural but man-made. So synthetic sapphire is a sapphire made in a lab and synthetic diamonds are diamonds that are made in a lab. Exactly the same material just man-made. The word you are after for not real or fake is simulant/simulated. Things like CZ and Moissanite would be a simulant.

    DeBeers hasn't had a monopoly on diamonds in years. Lab grown diamonds are OK and can be enjoyed in jewelry as long as you know that they are not natural diamonds, since these are naturally scarce and hold more value to people who appreciate diamonds. GIA is simply advocating for transparency and full disclosure. They are not working for DeBeers. Thank God GIA is there to stop the scammers who will try to pass off lab grown diamonds as natural ones.

JCK show 2019 really opened the synthetic diamonds, we are two watchmakers that are as thrilled as one can imagine since being into the lab grown diamond knowledge base since 2005. Very much for these two guys to think about is there in fact a value because of the the geological time effort versus the synthetic time efforts? Lance & Patrick.

    It is becoming more difficult for small time diamond buyers like myself with the consumer market buying these synthetics. There is without a doubt more marketing on these stones than natural diamonds to the retail market. Without advanced equipment some of these are extremely difficult to tell apart from natural stones. Not to mention the majority of synthetics cost just as much as natural diamonds, yet have almost no value in the secondary market. Thanks for the info!

    I don't understand why they are still so expensive and I will always love the genuine natural diamonds hands down. OK I admit that mining can be dangerous and lab created diamonds stop things like "blood diamonds!" so for that matter alone lab created diamonds are a lot safer, however I would rather have a natural real grown diamond any day. My conscience would be far clearer especially when I buy a diamond solitaire as a gift for someone special.

    That's right. Back in the late nineteenth century, they started creating lab grown rubies. They became all the rage back then because people who could not afford a natural ruby could buy them at an affordable price. But as they produced more, the prices went down and people lost interest in them as an investment. They can now be had for a few dollars a carat. The same thing will happen with lab grown diamonds.

    Synthetic diamonds always will be very BAD product without any future. I will never support the sale of synthetic (also known as lab-grown) diamonds, because I always support hard-working miners especially in Africa, where mining industry is for local african miners everything. Without this job, many people will lose their jobs, so diamond is only one- this 100% natural product, that gives work and a lot of joy to many people in Africa and all over the world. Remember one thing: When you buy lab-grown diamonds many miners for which mining diamonds in the mine is the only source of income for themselves and their families lose their jobs every day ************** PLEASE RESPECT AND SUPPORT MINERS **************
