Our verdict
A pair of emerald-cut lab-grown diamond studs at 1.00 total carat weight, offered in three golds at $900, for someone who prefers the emerald shape and accepts the SI1+ clarity shown. Look elsewhere if you need a cut grade or a named lab behind the Certified label; nothing in the listing text supplies either.
- Best for
- Someone who wants emerald-cut lab-grown diamond studs in white, yellow or rose gold.
- Skip if
- You need a cut grade, a round shape or a named grading lab behind the Certified label.
Why 3.9/5: Lifted by a full spec sheet with shape, grades, size and a Certified label in the title; held back by the missing cut grade and the lack of any named lab or report behind that label.
The shape is the point of this JNCY pair: two emerald-cut lab-grown diamonds of .50 ct each, 1.00 total carat weight, held in prongs and fastened with push backs. They come in 14k white, yellow or rose gold at $900. The title includes Certified, but the text names no lab or certificate.

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
- Two emerald-cut lab-grown diamonds at .50 ct each with color (F-G) and clarity (SI1+) stated
- Three gold colors at the same $900 price
- Prong setting and push backs are listed, with length (in) given as 1/5 and width (in) as 1/8
Worth noting
- The emerald-cut stones have no cut grade listed
- Certified appears in the title, yet no certificate or grading lab is named in the listing
- Rhodium plating is limited to the white gold version
Questions before you buy
What stones are in these 1 ctw studs?
Two emerald-cut lab-grown diamonds at .50 ct each, 1.00 total carat weight, with Near Colorless (F-G) color and SI1+ clarity, set in prongs.
Which metals and what size does the listing give?
14k white, yellow and rose gold at $900, with rhodium plating on white gold only. The listing gives Earring Length (in) as 1/5 and Earring Width (in) as 1/8, with push backs.
Is there a certificate for these diamonds?
The title includes Certified, but the listing names no grading lab, report or certificate 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).
