Our verdict
Emerald-cut studs for someone who wants 2.00 ctw of lab-grown diamonds at $1,800 with color, clarity and size given. Look elsewhere if you need the certificate named, a cut grade, or clarity above SI1+; the listing gives no report details and no cut grade.
- Best for
- Someone who wants emerald-cut lab-grown diamond studs at 2.00 ctw in white, yellow or rose gold.
- Skip if
- You need the certificate named, a cut grade, or clarity above SI1+.
Why 3.9/5: Lifted by a full spec sheet with stone count, grades and size and a certified claim in the title; held back by the SI1+ clarity grade, the missing cut grade and no named certificate.
At 2.00 ctw, this stud pair carries two emerald-cut lab-grown diamonds of 1.00 ct each, prong set on push backs. The listing grades them near colorless (F-G) with SI1+ clarity and gives an earring length of 1/5 and a width of 1/8, both labeled in inches. It comes in 14k white, yellow or rose gold, 3 variants, all at $1,800, and the title calls the diamonds certified.

Shipping, returns and warranty
JNCY ships by USPS at no cost and says most items are made to order, about two weeks, with an estimated ship date on the product page (FedEx 2Day is $25 on US orders and does not shorten production). A signature is required on engagement rings, made-to-order designs and orders over $1,500. It also ships to Australia, Canada, France, Germany, Ireland, Italy, South Korea and the United Kingdom for a flat $50, with duties and taxes paid by the buyer. Returns: 30 days from the ship date for pre-designed styles returned unworn with their original documents, with a free FedEx label on US orders; the FAQ page says 7 days instead, so confirm before relying on 30. Warranty: free lifetime repair or replacement of manufacturing defects and two free cleaning visits in the first year; wear and tear, lost stones and clearance items are excluded.
Before you buy
JNCY Jewelers is a Miami jeweler whose domain was registered in 2020. Independent feedback is thin: a ProvenExpert page lists three ratings, all 5.00, from Facebook and The Knot with no review text, and searches on 19 October 2026 found no Trustpilot or BBB page for the store. JNCY's own pages disagree in places: the refund window is 30 days on the Refund policy page and 7 days in the FAQ, and the custom-bridal page says it offers no financing while the financing page lists several plans. The listing mentions a diamond certificate; check the report number against the listing when the piece arrives and keep the paperwork, because JNCY charges $100 for a missing one on returns. Payments accepted include major cards, Affirm, Shop Pay and PayPal.
What we liked
- Emerald-cut stones with a stated count, 1.00 ct each and 2.00 ctw in total
- Color (F-G) and clarity (SI1+) are stated
- Length and width are given as 1/5 and 1/8, labeled in inches
- The title states the diamonds are certified
- Three gold colors at one price of $1,800
Worth noting
- Clarity is listed as SI1+, while the round 2 ctw stud sibling lists VS
- No cut grade is listed
- The title says Certified, but the listing names no grading lab or report
Questions before you buy
What are the diamonds in these studs?
The listing gives 2 emerald-cut lab-grown diamonds of 1.00 ct each, 2.00 ctw in total, with near colorless (F-G) color and SI1+ clarity, set in prongs.
How big are the studs?
The listing gives an earring length of 1/5 and a width of 1/8, both labeled in inches. It does not give the stone dimensions in mm.
Does the listing say the diamonds are certified?
The title says Certified, but the listing text does not name a lab or give a report number.
Can I return it if I change my mind?
JNCY's Refund policy page gives 30 days from the ship date for pre-designed styles returned unworn with their original documents; US orders get a free FedEx label and international buyers pay return shipping. A missing diamond certificate costs $100. The FAQ page says refunds are possible for up to 7 days after delivery, so confirm the window before relying on 30 days.
How long until it ships?
JNCY says most items are made to order and take about two weeks; the product page, cart and order email show an estimated ship date. USPS shipping is free, and FedEx 2Day ($25 on US orders) does not shorten production.
Are lab-grown diamonds real diamonds?
GIA says laboratory-grown diamonds have the same crystal structure as natural diamonds, tightly bonded carbon atoms, and nearly the same chemical, optical and physical properties. By eye the difference can be indistinguishable, but gemological laboratories can detect the different growth history with advanced instruments. They are grown by high-pressure high-temperature (HPHT) or chemical vapor deposition (CVD).

What we couldn’t verify
- The title says Certified, but no grading lab or report number is given and no cut grade is listed.
- The listing does not explain how the 1/5 length and 1/8 width were measured.
- Independent testing or appraisal: we found none for this piece; the only outside feedback is a ProvenExpert page with three 5.00 ratings (two Facebook, one The Knot) and no text.
- JNCY's pages disagree on the refund window (30 days on the Refund policy page, 7 days in the FAQ).
- We have not seen this piece's diamond certificate; the grades come from the listing.
