What to Consider Before Buying an Engagement Ring from Blue Nile

Updated

Before buying from Blue Nile, decide on four things in this order: diamond shape and budget, setting style, ring size, and whether you want a ready-to-ship ring or a made-to-order one. Blue Nile's site is built around a "start with a diamond" or "start with a setting" flow, so settling these first keeps you from redoing the search. The site also lists a phone line (+1-800-242-2728), physical stores, and virtual appointments if you want help before ordering.

Start with the diamond: shape, then budget

Blue Nile organizes loose diamonds by shape, and the shape you pick narrows both price and the look of the finished ring.

  • Shapes listed on the site: round, princess, cushion, emerald, pear, oval, radiant, Asscher, marquise, and heart.
  • Diamond types: natural diamonds, lab-grown diamonds, and colored diamonds are separate categories. Lab-grown stones are typically the lower-cost route to a larger look, while natural stones carry the traditional resale and rarity expectations. Decide which matters more to you before you filter.
  • Budget approach: set a total budget first, then split it between stone and setting. Because Blue Nile sells the stone and setting separately in its design flow, you can see each cost before committing.

A practical example: if your budget is fixed, choosing an oval or cushion stone instead of a round one often leaves more room for a more elaborate setting, since round stones carry a price premium for the same quality.

Choose the setting style

Settings are grouped by style on the site, and the style changes both the visual size of the stone and the maintenance involved.

Setting style What it does Consider if
Solitaire Puts all attention on one stone You want a classic look and lower setting cost
Halo Ring of small stones around the center You want a larger visual footprint from a smaller center stone
Three-stone Center stone with side stones You want a symbolic or more elaborate look
Sidestone Small stones along the band You want sparkle without a full halo
Vintage Milgrain and older-style detailing You prefer antique-inspired design

The site also lists gemstone and men's engagement options, plus designer collections such as Six by Royal Asscher and rings by James Allen. Designer collections usually cost more than the standard catalog for a similar style, so compare the same shape and carat weight across both before deciding.

Confirm ring size before you order

Blue Nile publishes a ring size guide, and you should use it rather than guessing. Ring sizing varies by band width and style, and a resize on an engraved or detailed band can be limited. Measure at the end of the day when fingers are largest, and if you are between sizes, size up. For a surprise proposal, confirm the size from an existing ring the person wears on the correct finger.

Ready-to-ship vs. made-to-order

The site separates ready-to-ship engagement rings from rings you configure yourself.

  • Ready-to-ship: a specific stone-and-setting combination already assembled. Faster delivery, but you accept the exact stone listed.
  • Design your own: you pick the diamond and setting separately, which gives full control over shape, quality, and metal but takes longer to produce.
  • Metal choice: yellow gold, white gold, rose gold, and platinum are listed across wedding and fashion rings. Platinum costs more upfront but wears differently than white gold, which needs periodic re-plating.

If you have a deadline, filter to ready-to-ship first and see whether any combination matches your must-haves. If not, build the ring and confirm the production timeline before ordering.

Check the buying terms and promos

The site advertises free shipping and free returns, and the homepage shows rotating promotions such as seasonal discounts on select jewelry and a free gift above a purchase threshold. Read the asterisk terms on any promotion, since select-jewelry discounts usually exclude certain categories. Also confirm the return window and whether engraved or custom pieces are excluded before you order.

When to use a store or virtual appointment

Blue Nile lists physical store visits and virtual appointments. Use a virtual appointment if you want to see a stone on video or ask about a specific setting before buying; use an in-store visit if seeing the ring in person matters to you. Both are worth booking before a high-value purchase, especially for a shape you have not seen in person, such as an emerald or Asscher cut where clarity is more visible.

A short pre-purchase checklist

  1. Pick a shape and set a total budget.
  2. Decide natural vs. lab-grown.
  3. Choose a setting style and metal.
  4. Confirm ring size with the site's guide.
  5. Decide ready-to-ship vs. design-your-own based on your deadline.
  6. Read the current promotion terms and the return policy.
  7. Book a virtual or in-store appointment if you want to see the stone first.
