How to choose
How to choose a lab-grown diamond engagement ring
Start with the shape
The shape sets the personality of the ring. Round brilliants return the most sparkle. Ovals, pears and marquise cuts look larger for their carat weight and lengthen the finger. Emerald and Asscher cuts trade sparkle for long, mirror-like flashes of light. Cushion, radiant and princess cuts sit in between, with soft or crisp corners.
| Shape | Known for |
|---|---|
| Round | The most sparkle |
| Oval, pear, marquise | Look larger, lengthen the finger |
| Emerald, Asscher | Mirror-like flashes |
| Cushion, radiant, princess | Sparkle with soft or crisp corners |
Pick a setting style
A solitaire keeps all the attention on one diamond. A hidden halo adds a secret row of diamonds under the center stone, seen from the side. A halo frames the center and makes it look larger. Three stone rings add two side diamonds. If she works with her hands, a lower setting or a bezel protects the diamond best.
14K or 18K gold?
Both are solid gold. 14K gold is 58.3% gold and a little harder, a practical everyday choice. 18K gold is 75% gold, with a richer color and a slightly higher price. Yellow, white and rose gold come in both.
| 14K | 18K | |
|---|---|---|
| Gold content | 58.3% | 75% |
| Feel | Harder, everyday | Richer color |
Choose your carat and budget
Every design offers a center diamond from 1 carat, and many go to 5 carats or more. Because lab-grown diamonds cost far less than mined diamonds of the same size, many couples choose a larger stone than they first planned. See the starting price for each carat above.
Know what certified means
Every center diamond of 1.00 ct and above is graded by IGI and ships with its report. The report confirms the shape, carat, color, clarity and cut. Smaller accent diamonds are hand-selected and not individually graded.

Questions
Engagement ring questions
Still deciding? A diamond specialist can walk you through options by video or phone.
Are lab-grown diamonds real diamonds?
Yes. Lab-grown diamonds have the same chemical, physical and optical properties as mined diamonds. They are grown in a controlled environment instead of mined, which is why they cost far less for the same size and quality.
What diamond quality do you use?
Our engagement ring center diamonds are E–F color and VVS1–VVS2 clarity, with an Excellent or Ideal cut. The grade stays the same at every carat weight.
Does every engagement ring come with a certificate?
Every center diamond of 1.00 ct and above comes with its own IGI report. Small accent diamonds are not individually graded.
How long will it take to receive my ring?
Each ring is made to order in 2–3 weeks, then ships free and fully insured by DHL or FedEx, arriving in 2–5 business days with a signature required.
I’m proposing on a specific date. When should I order?
