Why a lab-grown ruby works in an engagement ring

A lab-grown ruby is corundum, rated 9 on the Mohs scale, so a lab-grown ruby ring resists scratches and chips well enough for daily wear. It has the same crystal and color as a mined one, grown under controlled conditions, so it shows a clean, even red at a far lower price than a natural ruby of similar quality.

Styles and center shapes

  • Solitaire: the lab-grown ruby alone on a plain or pavé band.
  • Halo and double halo: a frame of lab-grown diamonds brightens the red center.
  • Side stone and three stone: lab-grown diamonds flank the center, including marquise, pear and baguette shapes.
  • Vintage and floral: milgrain, filigree and petal details.

Oval and cushion show a lab-grown ruby's color most evenly, round gives the most sparkle, and pear, marquise and heart make a lab-grown ruby ring stand out.

Carat weight, metal and price

Every design offers 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K. Yellow and rose gold deepen the red, while white gold, platinum and silver make it look brighter and cooler. Rings start under $300, and most are between about $750 and $1,050 at their smallest option.

Made to order

Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.

Lab-Grown Ruby Rings FAQs

How much do ruby rings cost?

Lab-grown ruby rings here start under $300, and most are between about $750 and $1,050 at their smallest option. The price rises with total carat weight, metal and karat, and with the lab-grown diamond accents a setting carries. Natural rubies of fine color cost far more. Lab-grown rubies have little resale value, so choose one to wear rather than as an investment.

Is ruby good for an engagement ring?

Yes. A lab-grown ruby is 9 on the Mohs scale, harder than nearly every gem except diamond, so it stands up well to daily wear. You can wear it in the shower, though soap film dulls the shine, so clean it now and then with warm water and mild soap. Take any ring off for heavy work, chlorine pools and harsh cleaners, which can harm the metal and loosen settings.

What color ruby is most expensive?

The most valued natural ruby color is a pure, vivid red to slightly purplish red with strong saturation, often called pigeon's blood in the trade. Pinkish, brownish or very dark natural rubies are worth less. That rarity drives the price of natural rubies. A lab-grown ruby can show a rich red without that premium.

What is the best cut for a ruby ring?

Oval and cushion are the most popular cuts for a lab-grown ruby, because they keep more of the crystal's weight and show its color evenly. Round gives the most sparkle, and emerald cut shows depth in long, clean flashes. Every ring here comes in round, oval, cushion, princess, emerald, pear, marquise or heart, so you can match the cut to the setting style you like.

Do rubies look better in gold or silver?

Both work, and each changes the look. Yellow and rose gold warm the red and make it look deeper, a classic pairing. White gold, platinum and silver give a cooler, brighter contrast that makes the red stand out sharply. Every ring on this page comes in all of these metals. For a ring worn every day, gold or platinum keeps its shape and finish better than silver.
