The Sagitta knife-edge solitaire blends earthy design with a sculptural edge. The 3mm knife-edge band is carved with a feather motif and lined with a delicate beaded spine that carries 18 white diamonds, ending in a 1ct round brilliant center stone. The feather carving, the beaded spine and the claw prongs are a tribute to birds, which is where the ring gets its sense of freedom and flight.

It sits low. That is the point of the design, and it is why this one suits an active hand: nothing stands proud of the finger to catch on a glove or a rope. Heather built it for the free spirit who wants a bohemian ring that still behaves like an everyday ring.

You choose two things on this listing. The center stone is lab grown or natural white, both 1ct round brilliants at VS1 clarity and F color or better. The metal is 14k or 18k yellow, white or rose gold, or platinum, cast from casting grain produced from reclaimed scrap, in a matte, satin or shiny finish. Prices run from $4,450 for a lab diamond in 14k gold to $8,250 for a natural white diamond in 18k gold or platinum, and every combination takes 4 to 6 weeks to make. Browse the full range of engagement rings, or pair this with the Sagitta Diamond Contour Band.

Fairmined gold is available on request at a premium. More on where the metal comes from.

What comes fixed on this ring, and what do I choose?

The 3mm feather-carved knife-edge band, the beaded spine and the 18 white diamonds set along it are part of the design and come with every version. You choose two things: the center stone, either a lab grown or a natural white 1ct round brilliant, and the metal, in 14k or 18k yellow, white or rose gold, or platinum. The finish can be matte, satin or shiny.

What is the difference between the lab grown and the natural white center stone?

Both are 1ct round brilliants at VS1 clarity and F color or better, hand-selected for brilliance, and set the same way in the same claw prongs. The natural stone is sourced through Kimberley Process compliant channels. The difference you will feel is price: $4,450 against $7,450 in 14k gold. Neither choice changes how long the ring takes.

Is this ring low enough to wear every day?

That is what it was designed for. The knife-edge band is 3mm and the setting is low profile, so the ring does not stand up off the finger the way a raised solitaire does. It suits an active lifestyle, and the feather carving hides ordinary wear better than a plain polished band would.

How long does the Sagitta knife-edge take to make?

4 to 6 weeks, whichever center stone and metal you choose. If you are working toward a date, put it in the notes at checkout and tell us when you need it. Often a shorter timeline costs nothing extra, and when it does, rush fees may apply. The FAQ page explains how rush pricing works.

Can I put a different stone in the center?

Yes. The center can be a salt and pepper diamond, a fantasy cut gemstone or a Montana sapphire instead of the round brilliant, and heirloom stones are welcome if you want the ring to carry something you already own. Ask and Heather will quote the change before anything starts.

Can a 3mm knife-edge band be resized, and can I return it afterward?

Yes, and resizing a knife-edge band like this takes about 2 weeks. Know this before you do it: once a ring has been resized it is final sale and cannot be returned. If you are unsure of your size, ask for a wax mold to try on before the ring goes into production and the resize never has to happen.
