Details
Round side stones soften the square without hiding a corner. Two round lab-grown diamonds sit beside the princess center, close enough to read as one group yet placed so they never cover its corners. Claws hold the center at each point, and the side stones have prongs of their own. The plain band tapers slightly toward the back of the finger. Rounds beside a square make a softer three-stone than baguettes or trillions. A good fit if you want classic sparkle across the hand.
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
Do the side stones cover the center's corners?
No. The round lab-grown diamonds sit beside the princess cut, not over its points, so each corner keeps its own claw. That matters for durability, because a claw over the corner is what protects a square stone from chipping. It also keeps the outline of the center crisp when you look at the ring from above.
How does this differ from the baguette three-stone?
Round side stones sparkle in small bright points, matching the brilliance of the princess center, while baguettes flash in longer, flatter planes. Rounds also bring a softer outline next to the square. Choose rounds for a more traditional, lively look, and choose baguettes if you want a sharper, more architectural line across the finger.
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.
