Our verdict
Suited to someone who wants a single-stone emerald-shaped ring of 1.00 ct with an excellent cut and IGI named, at $1,800. Look elsewhere if you want side stones or need a report number in the listing. The main caveat is that no stone dimensions are given.
- Best for
- Someone who wants a single emerald-shaped diamond with the cut grade and IGI named in the listing.
- Skip if
- You want side stones, a wider band or stone dimensions in millimeters stated in the listing.
Why 3.9/5: Lifted by a full spec sheet that includes a cut grade, a certified claim in the title and IGI in the details; held back by missing stone dimensions and the lack of a report number.
An emerald-shaped lab-grown diamond of 1.00 ct is the only stone in this JNCY solitaire, held by claw prongs on a band with a 1.8 mm average width. It comes in 14k white, yellow or rose gold in sizes 4 to 10, which gives 75 variants, and each one costs $1,800. Its diamond details list colorless (D-E) color, VS2+ clarity, an excellent cut and IGI as the certification.

Options and pricing
The three metals are 14k white, yellow and rose gold. Each comes in 25 sizes from 4 to 10, and all 75 variants share the $1,800 price. Only white gold is listed with rhodium plating. The listing gives a weight of 2.79 g without naming a metal.
How it compares
The 1.33 ctw Emerald Lab Grown Certified Diamond Pave Engagement Ring also lists $1,800 but is a pave ring with a 1.33 ctw total, where this ring is a single stone. The 1 ctw Emerald Lab Grown Diamond Wide Band Solitaire Engagement Ring lists $1,500 and is named a wide band, against $1,800 and a 1.8 mm width here. The 1.33 ctw Pear Lab Grown Diamond Classic Pave Engagement Ring lists $1,750 with a pear center.
Shipping, returns and warranty
JNCY ships by USPS at no cost and says in-stock items such as this one go out within one to four business days (FedEx 2Day is $25 on US orders). 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, one free resizing in the first year for standard ring sizes 4 to 10 (not eternity bands) and two free cleaning visits; 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
- Excellent cut, colorless (D-E) color and VS2+ clarity are all listed for the 1.00 ct emerald-shaped diamond
- The title calls the diamond certified and the details name IGI as the certification
- Claw prongs, a 1.8 mm average width and a 2.79 g weight are stated
- A single $1,800 price covers 3 metals and 25 sizes
Worth noting
- The IGI certification comes without a report number
- No stone dimensions in millimeters are listed, so the emerald shape's proportions are not stated
- The 2.79 g weight is not tied to one of the three metals
Questions before you buy
What are the grades of the diamond in the 1 ctw emerald solitaire?
One emerald-shaped lab-grown diamond of 1.00 ct with colorless (D-E) color, white hue, VS2+ clarity and an excellent cut.
Is the emerald solitaire's diamond certified?
The title calls it certified and the diamond details name IGI as the certification. The listing does not give a report number.
Which metals and sizes does the emerald solitaire come in?
Choose 14k white, yellow or rose gold, with sizes 4 to 10. All 75 variants are $1,800, and rhodium plating is listed for white gold only.
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 in-stock items ship within one to four business days by USPS at no cost, and FedEx 2Day costs $25 on US orders. Signature is required on engagement rings and orders over $1,500.
Does JNCY resize rings?
The warranty page offers one complimentary resizing within a year of purchase for standard ring styles in sizes 4 to 10, up or down one size, except eternity bands; larger changes may cost extra, and rings resized by another jeweler lose the warranty.
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).
