Round Brilliant Lab Grown Diamond Four Prong Solitaire Ring on a Fine Band

A round brilliant lab grown diamond held in four prongs on a fine plain band. This is the engagement ring in its original form, the design every other setting is a variation on, and there is nothing here that is not load bearing. Four claws, one shank, one stone.

The round brilliant is the most efficient diamond cut ever calculated. Its fifty seven facets are angled to return almost all the light that enters the table straight back to the eye, which is why a round sparkles harder than any other shape at the same weight. A four prong setting exposes more of that stone than six, and a fine band leaves nothing beside it to compare against, so the diamond is the whole ring.

Center stone details

  • Carat weight: 2, 3, 4 or 5 carat, selected at checkout

  • Setting: Four rounded claw prongs on an open basket
  • Certification: IGI certificate of the center stone is included at no extra charge

Band details

The shank is a fine rounded band with a smooth polished surface, unbroken from the head all the way round. No pave, no milgrain, no split. Because the band is narrow the stone looks larger, and because it is plain the ring will still look right in thirty years when whatever is fashionable now has passed.

Metal options

Choose from 925 sterling silver, or 10K, 14K and 18K gold in yellow, rose or white. Yellow gold is the traditional pairing and gives the round a warm halo of reflected light. Rose gold reads softer and more contemporary. White gold and sterling silver make the setting vanish so the diamond appears unsupported. Every metal is finished by hand in our workshop.

Ring size

This ring is available in a full range of US sizes. Select your size at checkout. If you are unsure of the size, contact us and we will help you measure at home before the ring is made.

Custom orders

We make every ring to order, which means the design can be adjusted. Ask us about six prongs instead of four, a hidden halo, a pave shank, a different carat weight, an engraving inside the band or a matching wedding band. Write to us through https://mapplegems.com/pages/contact and a member of our team will reply with drawings and a quote.

Frequently asked questions

Four prongs or six?
Four prongs cover less of the stone, so more of the diamond is visible and the outline stays square and clean. Six prongs cover a little more but spread the hold further. Both are secure. We can build this ring either way.

Why is a round brilliant the most popular cut?
Because its facet geometry was designed specifically to maximise returned light. No other shape sparkles as hard for the same weight, and it suits every hand and every setting style.

Does a plain band make the diamond look bigger?
Yes. There is nothing beside the stone for the eye to measure it against, and a narrow shank makes the head look proportionally larger than the same stone on a wide or stone set band.

Is a lab grown diamond a real diamond?
Yes. A lab grown diamond has the same carbon crystal structure, hardness, refractive index and fire as a mined diamond. The only difference is that it was grown in a controlled environment rather than pulled from the ground.

Will I receive a certificate?
Yes. An IGI certificate for the center stone is included with every order at no additional cost.

Can this ring be resized?
Easily. A plain unstoned shank is the simplest kind of band to size up or down, which makes this a practical choice if you are not certain of the size.

Which metal is best for daily wear?
14K and 18K gold are the most durable choices for a ring worn every day. 10K is harder still. Sterling silver is softer and suits gentler wear or a first ring.

Why buy a lab grown diamond

A lab grown diamond gives you the same optical and physical properties as a mined stone at a far better price for the size and quality. Because the growth conditions are controlled, high color and high clarity stones like the E VVS2 used here are available in large carat weights that would be rare and costly in mined goods. It is also a traceable choice, with a known origin and no mining footprint.
