This isn’t just a tennis necklace—it’s a masterclass in precision, balance, and brilliance.

Featuring a total of 40.00 carats of natural, earth-mined diamonds, this graduating diamond tennis necklace is designed to create a perfectly balanced visual flow. At the center sits a striking 1 carat emerald cut diamond, gradually tapering down in size with flawless symmetry toward the back, ending in refined 0.25 carat diamonds for a comfortable and elegant fit.

The result is a smooth, uninterrupted transition of size and brilliance—what we call perfect graduation.

Perfectly Matched. Perfectly Balanced.

Every diamond in this necklace is individually hand-selected and matched for:

  • Size
  • Color
  • Clarity
  • Brilliance

Out of thousands of diamonds reviewed, only a small percentage meet our strict standards. We reject stones with haziness, poor light performance, visible inclusions, or off-color tones.

Only diamonds that meet our top 5% quality criteria are used—ensuring this necklace delivers consistent sparkle from the largest center stones to the smallest diamonds in the back.

Graduation That Feels as Good as It Looks

This necklace isn’t just designed for visual impact—it’s engineered for wearability.

  • Front Section: Larger 1.00ct to ~0.30ct GIA-certified diamonds (45 stones)
  • Back Section: 0.25ct diamonds (55 stones) for comfort and flexibility
  • Smooth Transition: No abrupt size changes—just seamless flow

This thoughtful graduation ensures the necklace sits naturally on the neckline while maintaining maximum brilliance where it matters most.

Dino and the team at Diamond Mansion put together the perfect engagement ring. The whole process was low pressure and very easy. They knew exactly what I was trying to do, and they executed it perfectly. If I had known the whole process could be this easy, I would have come into it with much less apprehension. My fiance looked at the ring and thought it was a joke...it was "too perfect." I think that's the best review I could leave. Highly recommended.Read More

I just purchased my engagement ring from Diamond Mansion Co. I had a great experience working with Dino. The ring turned out better than expected and Dino overnighted delivery to me so I would get it in time. The customer service, price, and quality were all amazing!Read More
