Before you order
Good to know
When will it arrive?
About 4–5 weeks to your door. Every piece is made to order in our studio, then shipped free, fully insured and signature-required.
Have a proposal or wedding date? Tell us before you order and we'll confirm honestly whether we can make it.
How do I get my size right?
Please take a minute with it. Use our printable sizing guide at 100% scale, measure at the end of the day, and measure twice. Quarter sizes are fine, and we can work from US, EU or mm. We confirm your size with you before we start.
If your size ever changes, our family team will walk you through the options, but a ring built in your size from day one always wears best.
Engraving & Stone Inlay®: what's included?
Both are on us. Engraving: up to 9 characters, spaces included (like “J&A 2027”). Your handwriting is free too. A custom font or placement is $75, since it needs its own CAD.
Stone Inlay®: two small birthstones set into your band, often yours and theirs.
Will I see my diamond before it's set?
Yes, on every order. Within 24 hours we send a video of your exact diamond and its IGI report (DEF color, VS2+ clarity). Approve it, and that's the stone we set. Prefer natural? Request a natural diamond.
Is it ethically sourced?
Your alexandrite is lab-grown, with the true color change of the natural stone: green by day, violet by lamplight. Natural alexandrite is one of the rarest mined gems. Ours gives you that same change with no mine behind it.
It comes with a report from AGL (Antwerp Gemological Laboratory), so you know exactly what you're wearing.
Any diamonds on this piece, accents included, are lab-grown too.
Adding Stone Inlay®? Those birthstones vary: some are lab-grown and some are natural. Just ask about yours.
Can I return it?
You can cancel for a full refund before production starts. Once your piece is at the bench it's a final sale, since it's made to your exact choices. If it arrives damaged or has a craftsmanship issue, tell us within 14 days and we'll make it right.

The Solenne is a refined Toi et Moi ring that brings together two distinct forms of beauty in one elegant design. A 3ct cushion-cut Alexandrite sits beside a pear-cut diamond, each measuring 6x8mm, creating a balanced composition that feels both modern and deeply romantic.
The Alexandrite shifts between violet, berry, and blue-green tones depending on the light, while the pear diamond adds a bright, timeless contrast. Set side by side on a clean band, the two stones create a silhouette that feels graceful, symbolic, and effortlessly wearable.
Available in 14K gold or Platinum 950, The Solenne is made for someone who wants a ring that feels meaningful, elegant, and a little unexpected.

Find Your Ring Size
Measure Your Finger
- Use a flexible measuring tape or length of string.
- Wrap it around the finger you'll wear your ring on. If you're creating a ring stack, consider where on your finger the ring will sit. If using string, mark the point on the string where the ends meet with a pen.
- Lay the string on a flat surface and use a ruler to measure the length (in inches or millimeters) up to the mark. Compare your measurement to the size chart to determine your ring size. If you are between sizes, opt for the larger size.
Measure an Existing Ring
- Choose a ring that already fits your finger well.
- Measure the interior diameter of the ring in millimeters (mm).
- Use the measurement chart to match the size of your ring to the closest size in mm. The interior of the ring should align with the outer edge of the circle.
