An elongated marquise that flatters every hand — over a carat of real diamond in solid 14K gold.

The UXV 14K Solid Gold Lab-Grown Marquise Diamond Ring centers a 5 × 10mm marquise-cut lab-grown diamond, set north-south in secure claw prongs and flanked by two round brilliant lab-grown diamonds on a delicate 1.5mm band. With a total diamond weight of 1.08 ct, the long, pointed marquise shape makes fingers look longer and slimmer while giving more visible size per carat than almost any other cut. A timeless engagement ring, promise ring or self-purchase statement, made of solid 14K gold and shipped with an IGI diamond certificate.

How to measure: Measure the inside diameter of a ring that already fits the same finger, or wrap a strip of paper around the base of your finger, mark where it overlaps and measure the length. Match it to the guide above. Measure at the end of the day, when fingers are largest. Between sizes? Choose the larger size. Buying it as a surprise engagement ring? Borrow one of her rings and measure the inside diameter.

Styling tip: Pair it with our 14K Gold Lab-Grown Baguette Diamond Ring or a plain gold band for a bridal stack.

Frequently asked questions

Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds are real diamonds made of pure carbon, with the same chemical, physical and optical properties as mined diamonds. They are not simulants like cubic zirconia or moissanite.

Is the diamond certified?
Yes. Your ring comes with an IGI (International Gemological Institute) certificate for its lab-grown diamonds.

How many carats is this ring?
The total diamond weight is 1.08 ct, including the 5 × 10mm marquise center stone and the two round side stones.

What is a marquise diamond?
A marquise is an elongated, boat-shaped brilliant cut with two pointed ends. Its long shape spreads the carat weight over a larger surface, so it looks bigger than a round diamond of the same weight and makes fingers appear longer.

Is this a good engagement ring?
Yes. A certified 1-carat lab-grown marquise in solid 14K gold is a classic, durable engagement ring — and a more affordable way to get a larger, real diamond.

What's the difference between lab-grown and mined diamonds?
Only their origin. Lab-grown diamonds are created in a controlled environment instead of being mined from the earth. They look and wear the same, and they are a more affordable, traceable choice.

Is the ring solid gold or gold-plated?
Solid 14K gold through and through — not plated, gold-filled or vermeil. It's stamped 14K.

Which ring size should I choose?
Use the size guide above. The most common women's size in the US is 6–7. If you're between sizes, choose the larger size.

Can I wear it every day?
Yes. Diamonds are the hardest natural material and solid 14K gold doesn't tarnish. To protect the prongs and the pointed tips of the marquise, take it off for the gym, heavy lifting and cleaning with chemicals.

Does the price change by color?
No — yellow, rose and white gold are the same price. Only the ring size changes the price.

How long does it take to arrive?
Your ring is made in 1–5 business days, then shipped by insured express courier with signature required.
