1.17 Carat  ·  I3 Clarity  ·  Natural & Not Enhanced

Over one carat of natural, earth-mined diamond — the largest face-up spread,
the most commanding presence, and a stone that simply cannot be ignored.

The listing photographs show this diamond placed in a gold ring setting. At 6.9mm this is the widest of all our antique-character round brilliants — and in a solitaire setting, the difference is immediately and unmistakably visible. 1.17 carats commands the hand the way nothing smaller can.

Some stones are beautiful.
Some stones stop people mid-sentence.
At 1.17 carats and 6.9mm — this one does both.

There is a weight to 1.17 carats that you feel before you analyse it. At 6.9mm this round brilliant sits on the hand with an authority that smaller stones — regardless of their clarity grade — simply cannot replicate. The round brilliant is the most light-efficient diamond shape ever devised, and at this size, with this spread, it catches and throws light in a way that fills a room. This is the stone in this collection that draws the longest look.

I3 clarity means the inclusions in this diamond are visible — this is stated honestly and priced accordingly. What it also means is that you are getting a 1.17ct natural earth-mined round brilliant at 6.9mm for a price that reflects the clarity rather than the size. The size is extraordinary. The stone is not enhanced in any way. What you see in the photographs — in the tweezers and in the ring setting — is exactly what you receive.

In the great jewellery houses of the 19th century, stones were chosen for their presence — their fire in candlelight, their weight in the hand, their impact when worn. The finest pieces were not made with the clearest stones. They were made with the most compelling ones.

  • 1.17ct — the largest natural diamond in this collection
  • 6.90mm diameter — maximum face-up spread, immediately commanding
  • Round brilliant cut — engineered for light, built for presence
  • I3 clarity — inclusions visible; honestly disclosed, priced to reflect this fully
  • Not Enhanced — zero treatments, exactly as nature produced
  • Natural earth-mined origin — uncertified, honestly described
  • Photographed in a gold solitaire setting to show real-world face-up presence
  • For rings, pendants, and pieces where size and natural origin are the priority

I3 is the most included clarity grade on the GIA scale — the inclusions are visible to the naked eye, and this is fully reflected in the price. For buyers who understand that the purpose of a diamond is to be beautiful, worn, and loved — not examined under a microscope — a 1.17ct natural round brilliant at 6.9mm represents a compelling and honest value. Not Enhanced means no fracture filling, no laser drilling, no colour treatment. The stone is sold exactly as nature left it, exactly as described here.
