seems like we’re comparing apples to oranges here.. DeBeers’ new line is small, colored, lab diamonds pre-set into non-ring jewelry, whereas OP is looking for a large, white loose stone for an engagement ring.

djroomba :  i agree with @cpabee that in the short term (couple years) the type of lab grown diamond you are looking for isn’t likely to drastically change price. if you want to get engaged soon it’s worth getting it now! i think they’re priced well right now, my bf and I looked into them as an option and talked to a couple of suppliers who told us it’s a myth that it’s really cheap to produce high 4c stones at this point in time. we even saw lab stones that were below G color and SI1 clarity. yes the margin is high (as it is with mined diamonds) but cutting high 4c diamonds is still not a perfect science and costs them a lot. since the supply of that type of lab stone is low versus the growing demand for them, they can price them higher. even then, they turn through the inventory pretty quickly so could probably price even higher than they do. this is just what we heard from a couple of suppliers ๐Ÿ™‚ in the end my bf and i got a wholesale price on a beautiful mined diamond so it didn’t make sense for us but if we hadn’t gotten that deal we may have gone lab.

don’t stress too much, this is supposed to be an exciting time! best of luck with your search, it will all come together.

We got engaged in April last year with a lab diamond after we spent a long time researching 

We decided on a Brilliant Earth lab diamond for a number of factors – ethicality, price, quality, environmentalism, my science background. 

We also read this news about lightbox jewellery and I contacted Brilliant Earth for a response (because, you know, we spent $5k on the diamond and were concerned about devaluing our stone). Basically their response was that they are doing all the research they can into Lightbox’s plans and intentions, and believe that these stones will not be graded or of high quality. They will not be suitable for fine jewellery. They will not be cut well, for example. 

A significant amount of time and money goes into growing a lab diamond that is worthy of grading. Just like mined diamonds, it is a lottery how it will turn out when grown and then needs to be expertly cut into the best shape and carat for its properties. 

I highly doubt DeBeers has been able to come up with technology that means that they can grow perfect diamonds of at least a carat each and be able to flog them for $800 each. As another poster said, it was only very recently that they could even grow them near colourless. 

When this news came out, I did run to my fiancé and say ‘omg we just paid thousands for our stone, what do you think of this?’ 

And he said that he would still spend the same amount again and wouldn’t change a thing. 

I love my ring and my lab stone to death. I think it is stunningly beautiful. The love that I feel for it purely because of its meaning and significance for our relationship won’t be brought down by some cheap lab diamonds. 

Its the same reason why knock off designer stuff doesn’t bring down the value of the real thing ๐Ÿ˜‰

I vote get your lab diamond now. Live your life and create memories and have no regrets. DeBeers WANTS us to be doing and thinking this. Congrats on your pending engagement! Enjoy!

DeBeers has actually been growing lab diamonds for years for the industrial market, to learn about the differences and, most importantly, to learn how to identify lab vs mined diamonds. They are expert diamond growers ๐Ÿ˜€

They claim that the general public views lab diamonds as nothing more than costume jewellery so they are not selling the stones graded or using fine metals for their settings. They will offer both white (colourless to near colourless) as well as fancy colours.

I’m curious about the quality of the stones but given that moissy is a better price point, I’m not sure I would jump on the band wagon. 

OP I wouldn’t worry too much, you have a graded lab diamond given to you with love ๐Ÿ’•

I think that the cost of mined diamonds will also go down after all comes into play. Get whatever diamond you want whenever you want and don’t worry about what they’re doing. I think what they’re doing is going to backfire on them and also hurt their general industry. They are changing the market too much.

There’s an Etsy vendor, Alladin’s Cave, who took a lot of flack in some of these board threads for misrepresenting sims he was selling as “lab diamonds”. He changed his marketing a few months back. Now he’s listing at least 2 “real carbon lab diamond” solitaire rings in his shop, stone size 1 and 1.5 carat I think. They’re priced about $400 per carat. I have no idea if they’re real lab diamond or not, but I do think it’s a sign of things to come. Prices will definitely drop for “cultured” diamonds. That said, you could buy something less expensive now, & wait and see. Or get what you want. It’s such an emotional purchase. You’re the one who has to look at it every day. You should get what makes you happy.
