Our take on the Robin Hood Diamonds The Blair Solitaire Classic 4-Prong Diamond Engagement Ring

The Blair is a classic solitaire engagement ring built around a four-prong cathedral setting. The cathedral shoulders lift the center stone and open the sides to light, which is the main reason this style reads brighter than a low, closed basket. It is handcrafted in New York's diamond district from recycled precious metals and can be set with ten different diamond shapes, from round and oval to emerald, pear and marquise. It suits shoppers who want a plain, timeless solitaire rather than a halo or pavé band, and it competes directly with other cathedral solitaires on setting height and prong style rather than on extras.

Best forShoppers who want a plain, timeless solitaireBuyers set on a specific diamond shapeAnyone who prefers a raised cathedral settingShoppers who value US-made, recycled-metal jewelry
Pros
  • Four-prong cathedral setting opens the stone to light
  • Takes ten center diamond shapes, including step cuts and fancy shapes
  • Handcrafted in the US from recycled precious metals
  • GIA or IGI certified center stone
  • Comes as a complete ring with certificate and lifetime warranty card
Cons
  • A high cathedral head can catch on clothing and sit proud on the finger
  • Four prongs cover less of the girdle than six, so the stone is more exposed
  • No side stones or band detailing, so the look depends entirely on the center stone
  • Plain solitaire styling offers less sparkle across the finger than a pavé band

Questions and answers

What diamond shapes can the Blair be set with?
The setting accepts heart, round, oval, radiant, emerald, cushion, princess, pear, marquise and asscher cuts. It is built around your chosen center diamond rather than sold as a fixed stone.
Is a four-prong or six-prong setting better?
Four prongs leave more of the diamond visible and let in more light, which suits rounds and ovals. Six prongs hold the girdle more securely, which some buyers prefer for larger or softer stones.
What does the cathedral setting do?
The shoulders sweep up to meet the head, raising the stone above the band. That exposes the pavilion to light and gives the ring a taller profile than a low-set solitaire.
What comes with the ring?
A certificate of authenticity, a premium ring box, care instructions and a lifetime warranty card. The center stone is GIA or IGI certified.
Is the ring made in the US?
Yes. It is handcrafted in the New York City diamond district and made with recycled precious metals.
Will a high setting get in the way day to day?
A raised cathedral head can snag on knitwear and gloves and sits proud on the hand. Buyers who work with their hands often prefer a lower or bezel-set ring.
