Our take on the Certified 6.20 Ct Natural Diamond D Grade Round Loose VVS1 12.5 mm

This is a loose round brilliant-cut diamond of 6.20 carats and 12.5 mm diameter, listed as natural with VVS1 clarity and a D color grade. A stone that size and grade is a serious purchase, and the listing's $69.50 price at Etsy as of November 5, 2026 is far below what a natural diamond of these specs would normally cost. Treat the price as a red flag and verify the stone with an independent gemologist before buying.

Questions and answers

Is $69.50 a realistic price for a 6.20 ct natural diamond?
No. A natural diamond of this size and grade would normally cost tens of thousands of dollars. A $69.50 price at Etsy as of November 5, 2026 points to a simulant, lab-grown stone, or a misdescribed listing. Get it checked before paying.
What certificate should come with a stone like this?
A natural diamond of 6.20 ct should come with a report from a major lab such as GIA, AGS or IGI. Ask for the report number and confirm it on the lab's website. No certificate is named in this listing.
What does VVS1 and D color mean?
VVS1 means very very slightly included, with inclusions hard to see under 10x magnification. D is the top colorless grade. Both are high grades, which makes the low price more suspicious, not less.
What ring setting fits a 12.5 mm round stone?
A 12.5 mm stone needs a setting built for roughly 6 ct, with a sturdy head and band. Standard settings for 1 ct stones will not hold it. Have a jeweler set it.
Can I return it if it fails inspection?
That depends on the seller's policy, which is not shown here. Confirm the return window in writing before buying, and pay with a method that allows a dispute.
Where is the Certified 6.20 Ct Natural Diamond D Grade Round Loose VVS1 12.5 mm cheapest?
At Etsy, for $69.50, as of our latest check.
