Hi, today I have spotted a lab grown diamond company selling a new extra fine range of diamonds for this weekend only. There is no mention on the site/instagram stories/social media posts of whether they are lab grown or not. There is a little bit of text at the bottom of the website, (which most people won’t scroll down to), which mentions lab grown diamonds, however i don’t know if this applies to the actual diamonds or the lab grown ones?!
If they advertise as being a lab grown diamond company, then you should assume that any diamonds they sell are lab grown. Some companies feel that real diamonds are continuing the death trade wars in Africa where so many people are murdered, so they only deal in lab grown diamonds, which are less expensive also.

A lab diamond company will be selling lab diamonds - full stop. As long as they are not misleading customers by saying a lab grown diamond is a natural mined diamond its all good. Industry change can’t be stopped. Some jewelry stores that said they’d never sell jewelry with lab diamonds have relented and now lab diamonds account for 20% of their diamond jewelry sales.

As usual with scientific advances, two steps forward and one step back. At least the lab grown ones are the same ie carbon. It’s not the same for cubic zirconia (CZ) which is lab grown but is zirconium oxide and not zirconium silicate which is natural zircon, as often claimed by CZ sellers. It appears the rise of lab grown diamonds will continue to reduce prices for natural diamonds. This good for consumers who want the hardest gemstone known to man; and hopefully the public will see a decrease in cost, particularly for low quality and “doctored” diamonds in world markets.

Cz is very cheap. Lab grown diamonds are dropping in price quickly. An estimated 90% of both lab grown and natural stones are industrial diamonds. The demand for industrial uses, eg., cutting machine tools, grinding tools, etc. is insatiable. Gem quality synthetics were initially a problem, but the GIA is using advanced technology to detect what hitherto was not detectable. Both iron diffusion/catalyst for press grown diamonds and vapor deposition diamonds have inclusion and/or growth patterns that the GIA have been able to solve. Artificially irradiated natural white being sold natural green is still a problem that the GIA is working on. Most synthetic diamonds can be distinguished from natural by optical microscopy. Press grown ones are grown quickly, within a matter of a few months… the pressure is 5 GPa, temperature at 1000C… Ones that are a problem are those grown from a seed at 7 GPa for several years…the process is slower, pressure higher, to more closely mimic the natural environment in which diamonds form. Pure graphite and no iron diffuser is used, nitrogen can be flushed and excluded for type 2 diamonds.
