Details
Emerald-cut sides bring an Art Deco edge. Two emerald-cut lab-grown diamonds sit beside the princess center, their long step-cut facets giving a cool, mirrored flash next to the square's brilliance. Each side stone is held in four prongs, and the center's corners sit under claws. Below the stones the shank splits into a cathedral, supporting the head and opening up the side view. Straight lines and stepped facets nod to Art Deco design, for anyone drawn to vintage geometry.
Choose a princess center from 0.75 to 2.00 carats. Each center is a lab-grown diamond selected to a D to F color, VS2-or-better specification. Carat weights are nominal and each size has a published range; the 1.00 ct size, for example, runs 0.95 to 1.10 ct. Lab-grown diamonds are real diamonds, chemically and physically the same as mined ones. If you would rather pick an individually graded loose diamond, natural or lab-grown, build it in Design Your Ring.
Available in 14K white, yellow or rose gold, or platinum. The accent diamonds are lab-grown, near-colorless stones matched to the setting. Your ring is made to order in your size (US 3 to 10; see the sizing guide) and typically ships in about 5 to 10 business days by complimentary, insured UPS Express. More princess settings are in our Princess Cut Engagement Rings collection.

Answers, before you ask
Your Questions
How do emerald-cut sides look next to a princess?
Brilliant faceting makes the princess center sparkle in small bright points. The emerald-cut sides are step cuts, which show broad flashes and a hall-of-mirrors effect. Placed together they contrast: the center glitters while the sides glow in calmer planes, which frames the square and gives the ring its Art Deco character.
Are the side stones lab-grown diamonds too?
Yes. Both emerald-cut side stones are lab-grown diamonds. Their straight edges line up with the flat sides of the princess center, so the three stones read as one continuous row. Their corners are protected by prongs, just as the center's corners sit under claws, which matters for any stone with pointed or angular edges.
What quality is the center diamond?
Every princess center is a lab-grown diamond selected to a D to F color, VS2-or-better specification. Sizes are sold by nominal carat weight with a published tolerance range, so a stone may weigh slightly over or under the headline figure within that range. If you want a specific graded stone, Design Your Ring lets you choose one individually.
Can I have a natural diamond instead?
This ring is offered with lab-grown centers. For a natural diamond, use Design Your Ring to choose a natural loose diamond with its own grading report and set it in one of our settings, or email concierge@diamondandsapphire.com and we will help.
How long does it take to make?
Each ring is made to order in your finger size. Most ship in about 5 to 10 business days, insured and signature-required. The product page shows the current timing before you check out.
