Best lab diamond earrings on Amazon
For most buyers the best lab diamond earrings on Amazon are round studs of 1 to 4 carats total weight (half to 2 carats each) in solid 14k gold with screw backs, with IGI reports for both stones. Lab-grown diamond is real diamond, so studs this size cost a fraction of mined ones. Read "ctw" carefully: 2 ctw means two 1 carat stones, not two 2 carat stones.
How we pick: each entry is a kind of piece and the listing details that separate a good one from a bad one, with an Amazon search already narrowed to that spec. Pieces marked We own this are ones we bought with our own money; the rest we have not handled, so we tell you what to look for instead of pretending we tested them. Grades on listings are the seller's claims.
Round studs, 2 ctw (1 ct each)
Best for: Everyday diamonds that look substantial
One carat per ear (about 6.5 mm) reads as real diamond studs across a room without looking like costume jewellery.
Look for
- "2 ctw" or "1 ct each": make sure which
- IGI reports for both stones
- 4-prong or martini setting
- Screw backs, 14k solid gold
Larger studs, 3 to 4 ctw
Best for: Statement studs and milestone gifts
At this size lab diamond saves the most compared with mined diamond, and colour differences between the two stones start to show, so both reports should agree.
Look for
- Matched pair: the same colour and clarity on both reports
- Martini or basket setting to keep the stone secure
- Screw backs
Diamond huggies and hoops
Best for: Daily wear and stacking
Many small stones set in a hoop sparkle from every angle and cost less than one large stone of the same total weight.
Look for
- Total weight of the small stones, usually 0.5 to 2 ctw
- Hinged huggie closure
- Solid gold
Before you buy: the listing checklist
- Total weight (ctw) versus each stone: the listing must say which.
- Reports for both stones, or at least one for the pair, from IGI or GIA; look the numbers up.
- Screw backs or locking backs on anything above half a carat each.
- Solid 14k or 18k gold, stamped 585 or 750.
- A return window long enough to have them checked by an appraiser.
