The chart shows monthly US Google searches for Gemone keywords over the past 12 months. Interest stays between 520 and 780, with March the busiest, so it gives no clear sale season. BF20 and DIWALI20 were rejected in our test. Since standard shipping takes 10 to 15 business days, order early for a wedding, an anniversary or a holiday.

We have not bought from this store, so this is not our own review. A Google summary gave Gemone Diamond a Trustpilot score of about 4.5 out of 5 from 38 reviews when we checked, which is a small number for jewelry at these prices. As for whether it is legit, the site lists offices in Surat and Delaware, a New York showroom and a phone number. For a big purchase, ask for the IGI or GIA report number before you pay, and check it on the website of the lab.
