How Blue Nile's Design Your Own Ring Tool Works

Blue Nile's Design Your Own Ring tool lets you build a ring by choosing either the diamond first or the setting first, then combining the two into a finished piece. You can start from the diamond side (pick a stone, then a setting) or the setting side (pick a style, then a stone). The same start-with-a-diamond / start-with-a-setting structure also applies to designing your own earrings and pendants, and Blue Nile lists a separate Creative Studio as an online design entry point. This is a configuration tool for pairing stones and settings — not a fully custom CAD service — so it suits buyers who want to control the two main variables (stone and setting) within Blue Nile's existing catalog.

The two starting paths

The tool is organized around two entry points, and the order you choose mainly affects how you browse:

Neither path is "better" in general. Starting with the diamond makes sense if the stone is your priority and you want the setting to fit it; starting with the setting makes sense if you have a style in mind and want to see which stones suit it.

What you can specify

• Diamond shape: Round, princess, cushion, emerald, pear, oval, radiant, asscher, marquise, and heart are all listed as shop-by-shape options.
• Diamond type: Natural diamonds, colored diamonds, and lab-grown diamonds are separate categories, so the choice of stone type is part of the build.
• Setting style: Solitaire, halo, vintage, sidestone, three-stone, gemstone, and men's engagement styles appear as shop-by-style options.
• Metal: Yellow gold, white gold, rose gold, platinum, and silver appear across the jewelry catalog; the exact metals offered for a given setting depend on that setting.

The same flow for earrings and pendants

Blue Nile applies the identical structure to two other categories:

• Design Your Own Earrings — start with a diamond or start with a setting.
• Design Your Own Pendant — start with a diamond or start with a setting.

If you've already used the ring tool, the earring and pendant tools follow the same logic, so there's little new to learn.

Creative Studio and other design entry points

Alongside the start-with-a-diamond / start-with-a-setting tools, Blue Nile lists Creative Studio as an online design entry point, and it appears in the diamonds, engagement ring, and jewelry sections. The catalog also includes named collections such as SIX By Royal Asscher (curated by the Asscher family) and The Clear Cut, which are presented as curated or designer options rather than blank-slate builds. For guidance while configuring, Blue Nile provides education pages including a Diamond Guide and an Engagement Rings Guide, plus a Find Your Ring Size tool.

Practical notes before you start

• The site requires JavaScript. The page states you need to enable JavaScript to run the app, so plan to use a browser with JavaScript enabled rather than relying on a text-only view.
• Phone support is listed: +1-800-242-2728 appears on the site if you want to talk through a configuration.
• Promotions change. The page shows a seasonal promotion ("The Fall Edit: Up to 30% Off Select Jewelry") and a gift-with-purchase threshold ($1,500+ purchase). Treat these as time-limited offers tied to select items, and check the current terms on the site rather than assuming they apply to your build.
• Store and virtual appointments are listed as options if you want to see settings or stones before finalizing.

What this tool is and isn't

It is a pairing tool: you select from Blue Nile's existing diamonds and existing settings and combine them. It is not described as a bespoke design service where you submit original drawings or non-catalog components. If your goal is to control stone and setting within a known catalog, the tool covers it; if your goal is a one-of-a-kind custom design, the site's listed options don't indicate that capability.
