History, Types, Cultural Significance Of Marquise Cut Lab Diamond Engagement Ring

The marquise cut diamond has a royal legacy, originally designed for French royalty in the 18th century. Known for its elongated shape and pointed tips, the marquise cut creates the illusion of longer, slender fingers and delivers maximum surface brilliance—making it one of the most flattering diamond shapes you can choose.

In our curated collection of lab-grown marquise diamond engagement rings, you’ll find an array of styles—from sleek solitaires and double-band settings to vintage-inspired halos and east-west orientations. Each ring is made in 14K solid gold (available in yellow, white, and rose), chosen for both its elegance and durability.

These lab diamonds aren’t just beautiful—they’re ethically created in controlled labs using eco-friendly methods. Chemically and visually identical to mined diamonds, lab-grown marquise diamonds provide the same sparkle at a significantly more accessible price. That’s why they’re increasingly popular among modern American couples who want style, substance, and sustainability in one meaningful piece.

Whether you’re shopping for a unique engagement ring or looking to add a bold new shape to your fine jewelry collection, the marquise cut offers an edgy yet elegant aesthetic that transcends trends. Each ring is handcrafted by skilled artisans and checked for quality in multiple stages before being packaged and shipped.

A marquise engagement ring is more than a ring—it’s a conversation piece, a nod to classic beauty, and a choice made with intention.

Quality of Material Used

All marquise engagement rings in this collection are crafted using 100% solid 14K gold—never plated or filled. Whether you choose white, yellow, or rose gold, you're getting a premium foundation that lasts a lifetime. Our lab-grown diamonds are carefully selected for brilliance, symmetry, and clarity, ensuring every marquise cut captures light from every angle.

We also ensure that our jewelry is hypoallergenic and nickel-free, making it suitable for sensitive skin and everyday wear. Each ring is thoughtfully designed and structured for long-term durability and elegance, ensuring you’ll treasure it forever.

Certifications Provided

Your peace of mind matters. That’s why every lab-grown marquise diamond from The Karat Store comes with an IGI certificate, verifying the diamond’s authenticity, carat weight, color, cut, and clarity.

All gold used is BIS hallmarked to certify its 14K purity, and we provide a detailed invoice with every purchase to ensure full transparency. Certified jewelry not only adds credibility and resale value—it’s a symbol of trust and quality.

At The Karat Store, we include these documents with every ring, so you’ll always know the story behind your sparkle.

Craftsmanship

Each marquise diamond ring is handcrafted by experienced artisans who understand the intricate requirements of this distinctive shape. From the symmetry of the cut to the prong positioning at each pointed tip, marquise settings require extra attention to detail—and that’s exactly what we deliver.

Our jewelers use refined polishing, secure prong settings, and mirror finishes to highlight the stone’s brilliance and protect its edges. Before shipping, each piece is subjected to a multi-step quality inspection, ensuring that it meets our exacting standards. The result is a ring that looks refined, feels luxurious, and stands the test of time.
