Matilda vs. Fiona: Hidden Halo or Halo for an Oval Diamond?

Matilda and Fiona are two of our bestselling oval engagement rings, and two of our most popular designs on Pinterest this fall. Both hold an oval center stone, both use colorless accent diamonds, and both take about six to seven weeks to make. The big difference is the halo: Matilda hides hers under the stone, while Fiona puts hers on show.

If you're deciding between them, here's how they compare in look, band and price (prices as of October 2026).

Matilda: The Hidden Halo

A hidden halo is a row of small diamonds set underneath the center stone, on the part of the setting called the gallery. You don't see it from above. You see it from the side, and when it catches the light as your hand moves.

On Matilda, the oval sits on four prongs engraved like small leaves, and the band is a rope of diamonds about 2.5mm wide. In our guide to the best settings for an oval diamond, Matilda is shown with a 1.7ct oval in 14k rose gold. The band width helps, too: the same guide recommends a band with some width to balance the length of an oval.

Fiona: The Full Halo

Fiona surrounds the oval with a halo edged in milgrain, the fine beaded detail common in antique jewelry. A halo adds a ring of bright diamonds around the center, so from above the oval looks larger than its carat weight. Fiona's floral split shank opens around the halo with diamond-set curves, and at about 1.7mm the band is narrow, which also makes the center look bigger.

Our oval settings guide notes that a halo combined with a split shank draws the eye along the length of the ring, so Fiona reads as long and graceful on the finger.

What the $1,300 Difference Buys

In 14k gold, Fiona costs $1,300 less than Matilda at every carat size we compared, with the same center stone. The whole difference is in the setting: in 14k gold, Matilda's setting is $4,050 and Fiona's is $2,750.

That changes what your budget can do. In 14k gold, Fiona with a 1.50ct lab-grown oval is $4,700, which is less than Matilda with a 1.00ct lab-grown oval at $5,250. With a 2.00ct lab-grown oval, Fiona is $5,700 and Matilda is $7,000. With a 1.00ct natural oval (G, VS2), Fiona is $7,500 and Matilda is $8,800.

If size matters most to you, Fiona gets you a bigger center stone for less. If you want the clean top view and the rope band, Matilda is worth the difference. Our oval diamond size chart shows how each carat weight looks on the hand.

Choosing Metal and Color

Ovals tend to show more body color than round diamonds. Our oval settings guide recommends platinum or white gold for near-colorless E to G stones, and yellow or rose gold if you choose a diamond in the I to J range, since warm metal hides a slight warmth in the stone. Both rings come with E, VS1 lab-grown or G, VS2 natural ovals, in recycled 14k or 18k gold or platinum.

Wedding Bands for Matilda and Fiona

The longer the oval, the more of a straight wedding band it hides. Both product pages link to wedding bands we've paired with each ring, and a curved band that follows the oval is another option. Our guide to choosing a wedding band for your engagement ring explains how to get a good fit.

Frequently Asked Questions

What is a hidden halo?

A row of small diamonds set under the center stone instead of around it. It adds sparkle from the side without changing the view from above.

Does a halo make an oval diamond look bigger?

Yes. The ring of diamonds around the center makes the whole top of the ring look larger, which is why Fiona looks bigger than Matilda with the same oval.

Can Matilda or Fiona be made with a different shape?

Yes. Both product pages note that the design can be made with other center stone shapes. Matilda also comes as a marquise, pear and morganite version, and Fiona as a round and a pear.

How long do Matilda and Fiona take to make?

About six to seven weeks each.

Are lab-grown and natural diamonds both available?

Yes. Both rings are offered with lab-grown E, VS1 ovals or natural G, VS2 ovals, in recycled gold or platinum.
