JNCY 2 ctw Round Lab Diamond Solitaire Engagement Ring Review
The single lab-grown diamond in this solitaire is round and 2.00 ct, set on a 1.8 mm band in 14k rose, yellow or white gold at $2,250. IGI is named and no cut grade is listed, so it suits someone content with color and clarity grades alone.

Our verdict
Suited to someone who wants a round 2 ctw solitaire at $2,250 with IGI named and a choice of rose, yellow or white 14k gold. Look elsewhere if you need a cut grade or stone dimensions in the listing. The main caveat is that the grades cover color and clarity only.
- Best for
- Someone who wants a round lab-grown solitaire at 2 ctw in rose, yellow or white 14k gold.
- Skip if
- You need a cut grade or the stone's dimensions in millimeters stated in the listing.
Why 3.9/5: Lifted by a full spec sheet with color and clarity grades and a certified diamond stated in the title; held back by the missing cut grade and stone dimensions.
This JNCY solitaire holds one round lab-grown diamond of 2.00 ct, with colorless (D-E) color and VS2+ clarity in the listing. It is offered in 14k rose, yellow and white gold in sizes 4 to 10, as 75 variants priced at $2,250 each. The title calls it certified and IGI is named, while the listing gives no cut grade.

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
- A round diamond of 2.00 ct with color (D-E) and clarity (VS2+) grades listed
- IGI is named as the certification, and the title also says certified
- A single $2,250 price covers 3 metals and 25 sizes
- The band width of 1.8 mm is given, along with a 2.27 g weight
Worth noting
- The diamond details have no cut grade, only color and clarity
- No stone dimensions in millimeters are listed for the 2.00 ct round diamond
- The 2.27 g weight is not matched to one of the three metals
Questions before you buy
What stone does the 2 ctw round solitaire have?
One round lab-grown diamond of 2.00 ct, colorless (D-E), white hue, clarity VS2+. The details name IGI as the certification; there is no cut grade.
Which metals and sizes does the 2 ctw round solitaire come in?
14k rose, yellow and white gold in sizes 4 to 10. All 75 variants cost $2,250, and rhodium plating is listed for white gold only.
Does the listing say the round solitaire's diamond is certified?
The title says certified and the diamond details give IGI as the certification. No report number accompanies it in the listing.
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).
