The pattern
Notice the balance of light and dark in the actual stone. Its appearance can change with lighting and setting.
For a love unlike any other
Character. Not convention.
Choose a smoky pattern that feels like you. Explore natural and lab-grown stones, then create a custom engagement ring around your favourite.
Online stones are sourced to order, not available for showroom viewing. Speak with our jeweller before ordering.

All diamond prices on this page are in Canadian dollars (CAD), regardless of the site currency selector. Loose stone only; setting and applicable taxes are extra.
Checking current online diamonds…

Start with the look you love. Tell our jeweller your preferred shape, origin and budget, and we can discuss what to look for.
AI-generated design inspiration. Not an available ring or stone.
Online stones are sourced to order and are not available for showroom viewing before purchase. Open the diamond for details; copy its link to discuss that exact stone with our jeweller before ordering.
Loose-diamond listings are for the stone alone. Your finished-ring quote also depends on the setting, metal and design. Not every stone has an independent grading report—ask what documentation is available for your selection.
02 / Look a little closer
Salt-and-pepper describes visible inclusions, not one clarity grade. Compare the actual photograph, face-up dimensions and available video—not just carat weight.
Compare the actual stones
These 1.00 ct-and-above photographs come from the selection above. Compare patterns, silhouettes and the listed millimetres—not carat weight alone. Lighting and setting change appearances; these are not inclusion-density grades.
Notice the balance of light and dark in the actual stone. Its appearance can change with lighting and setting.
Carats measure weight. Millimetres show face-up size. Compare length, width and depth, especially with elongated shapes.
Rose cuts and brilliant cuts interact with light differently. Ask about the exact stone’s transparency and available photographs or video.
Diamond resists scratching, but it can still chip. Surface-reaching inclusions, thin edges and exposed points may increase risk. Discuss the particular stone and its setting with our jeweller before ordering; a protective design can reduce exposure, not remove every risk.
03 / Make it yours
A clean solitaire. A framing bezel. A balanced three-stone design. Start with the feeling you want, then explore shape, proportions and metal in Rudix Ring Studio. A design illustration is a starting point—not a photograph of your chosen diamond.

The whole picture
For a complete ring, ask for a quote separating the diamond, setting and metal, with taxes and any additional charges explained. Shape, dimensions and inclusion pattern matter alongside price.
A stone-only listing is not the price of a finished ring. For US delivery, import charges are additional and paid by the buyer.

04 / Buy with clarity
We ship to Canada and the United States only. Loose diamonds ship free, fully insured and signature required. Sourcing or custom production comes before dispatch; confirm your timeline rather than treating transit estimates as an order-to-door promise.
Read shipping detailsUS customs duties, tariffs, import taxes and brokerage fees are not included in our prices. They are the buyer’s responsibility, payable to the carrier on delivery. Free shipping does not mean duty-paid delivery.
Only diamonds marked or confirmed as returnable qualify for a return within 10 days of delivery. They must be unworn and unset, with the original certificate required by our loose-diamond terms, and a Return Authorization is needed. Ask us to confirm the documentation requirements for your stone before ordering.
We confirm returnability before sourcing. If a stone is final sale, we tell you before ordering and you may cancel for a full refund. Diamonds set into jewellery are final sale. Custom-made jewellery is also final sale; the general 30-day return headline does not apply to these purchases.
A few good questions
Yes. The name describes a visibly included appearance, not an imitation material. Natural and lab-grown describe different origins. Our finder separates those categories; check the origin on the individual listing.
Suitability depends on the individual diamond, its inclusions, cut and setting, as well as how the ring will be worn. Hardness does not make a stone immune to chipping. Discuss your shortlist and lifestyle with our jeweller before ordering.
No. Online loose stones are sourced to order and are not held in our showroom for pre-purchase viewing. Start with listing photographs and any available video, then consult our jeweller before ordering. A design consultation is not a stone-viewing appointment.
No. Ring Studio helps communicate layout, shape, metal and setting ideas. Your selected diamond has its own dimensions and inclusion pattern, and the final design must be planned around that particular stone.
No blanket report promise applies. Ask which independent report, identification details or other documentation is available for the exact stone you are considering before ordering.
Yes—our shipping policy supports the United States as well as Canada. US import duties, tariffs, taxes and brokerage fees are additional and buyer-paid. Confirm the quote, sourcing timeline and stone-specific return terms before ordering.
Something distinctive starts here
You do not need a finished design. A stone you like, a few saved ideas or a question is enough to begin.
