Our take on the Certified 8.40 Ct Natural Diamond D Grade Round Loose VVS1 14 mm

This is a single loose round brilliant-cut diamond listed at 8.40 carats and 14 mm across, described as natural with VVS1 clarity and D color. A stone of that size and grade would normally be a five- or six-figure purchase, so the listing's details matter more than the headline. The best new price is $120.80 at Etsy as of November 5, 2026, and only one store lists it, so there is no price history to compare against.

Questions and answers

Is $120.80 a realistic price for an 8.40 ct natural diamond?
No. A natural round diamond of that weight and grade typically sells for six figures. Treat a price this low as a red flag and ask for a GIA or AGS report before paying.
What grading report should come with it?
Ask for a GIA or AGS report with a report number you can verify on the lab's website. The listing does not name a lab or a certificate.
How big is a 14 mm round diamond?
14 mm across is roughly the width of a dime and a half, well beyond typical ring-center sizes. Expect a very tall setting and a heavy ring.
Can I return it if the grade doesn't match?
That depends on the Etsy seller's return policy, which is not stated here. Confirm the return window and get the grading claims in writing before buying.
Is it cheaper to buy the loose stone or a finished ring?
A loose stone usually costs less than the same stone in a finished ring, but you pay separately for setting and labor. Compare the total against a completed piece.
Where is the Certified 8.40 Ct Natural Diamond D Grade Round Loose VVS1 14 mm cheapest?
At Etsy, for $120.80, as of our latest check.
