The unit leverages a touch sensitive screen and sells for $9,500.

The FTC provides guidance on how diamonds (LGD and natural) should be marketed. Goal: Ensure that consumers are not misled by false claims. While the FTC sets these rules in the Jewelry Guidelines and the Green Guide, the terms are not legally binding . The FTC has taken precautionary action against eight companies that violated certain terms in 2019, but no law- suits were filed. Also, the Green Guide hasn’t changed since 2012, and again don’t expect them to uphold the law; they’re simply strong recommendations. Global organizations like the International Or- ganization for Standardization (ISO) establish canons for grading and terminology for natural and LGDs. We’ll examine such as we move worldwide, but again these are not laws . In the U.S., clear LGD ad disclosures are re- quired by literally spelling out wording as "lab- oratory-grown,” “laboratory-created,” or [man- ufacturer name]-created, although we’re using the acronym “LGD” herein. Ads in Europe, and a few in the U.S., don’t explicitly reveal LGDs as such. This has led to complaints from advertising authorities em- phasizing the need for conspicuous disclosure. Enter the Natural Diamond Council (NDC) and the World Federation of Diamond Bourses (WFDB) - they helped established one solid law in France: "Diamant synthétique" (synthetic di- amond) must be used in LGD advertisements. Engraving LGDs has become a standardized practice. This doesn’t mean all LGDs have full laser inscriptions, however. LGD engraving is not a legal mandate. Unregulated Laser-Inscriptions To date, the majority of LGDs carry a grading report from IGI, the same lab that stopped clear- ly denoting such on their LGD girdles. Now, these stones show an “LG” abbreviation with a corresponding grading report number accompa- nied with a printed LGD trifold. On the flipside, GIA, SGL and GCAL continue to engrave LGDs exactly as such with grading reports for LGDs.
