Our verdict
A 3 ct oval hidden halo ring at $3,800 with IGI named and grades for both the center and side stones. It suits a buyer who wants a larger oval and is comfortable confirming the total weight and metal with the store, since the title, the weight line and the stone counts disagree. Look elsewhere if you want a metal choice or a listing whose figures agree.
- Best for
- Someone who wants a 3 ct oval with a hidden halo and will confirm the weight and metal details with the store.
- Skip if
- You want a choice of metals or a listing whose title weight and stone counts match.
Why 3.8/5: Lifted by a full spec sheet that grades the center and side stones; held back by weight and stone counts that disagree with the title and by an unclear metal choice.
A 3 ct oval lab grown diamond with a hidden halo is the centerpiece of this $3,800 JNCY ring, whose title gives 3.44 ctw. The listing grades the center Colorless (D-E) with VS2+ clarity and IGI named, and adds 22 round side stones of .44 ctw. It comes in 13 sizes from 6 to 10, and the description names 14k yellow and white gold.

Options and pricing
The only option on the page is ring size, 6 to 10 in 13 sizes, and all 13 variants cost $3,800. The description says 14k yellow and white gold, but there is no metal selector, so it is not clear whether the ring is two-tone or comes in two versions. The width is 2 mm and the weight is 3 g.
How it compares
The Oval Lab Grown Diamond Pave Engagement Ring with Halo lists $3,750 with 2.02 carat weight and a 1.8 mm width, against $3,800 and a 2 mm width here. The Oval Lab Grown Diamond Hidden Halo Engagement Ring is $3,400 with 2.625 carat weight and a 1.8 mm width.
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, 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
- IGI is named for the 3 ct oval center stone, graded Colorless (D-E) with VS2+ clarity
- The 22 side stones are listed with their own grades: VS-SI+ clarity and an excellent cut
- Width (2 mm) and weight (3 g) are stated
- One price of $3,800 for all 13 sizes
Worth noting
- Only ring sizes 6 to 10 are offered, and there is no metal choice on the page
- The title gives 3.44 ctw but the ring information gives a total carat weight of 2.33
- No cut grade is listed for the oval center stone
Questions before you buy
What stones are set in this 3 ct hidden halo ring?
One oval lab grown diamond of 3 ct, Colorless (D-E) with VS2+ clarity and IGI named as the certification, plus 22 round lab grown side stones of .02 ct each totaling .44 ctw, graded VS-SI+ with an excellent cut.
Which metal and sizes are listed?
The description says 14k yellow and white gold. The variants list only ring size, 6 to 10, at $3,800, with no metal option.
Does the 3.44 ctw in the title match the rest of the listing?
Not fully. The title says 3.44 ctw, the diamond details list 3.00 for the center and .44 for the side stones, and the ring information gives 2.33. The listing does not explain the mismatch.
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.
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).
