More: Lab Grown Diamond Rings · Lab Grown Diamond Jewelry · How to find your ring size
A radiant cut lab-grown diamond framed by a halo, set on a band with three rows of pavé running down the shoulders. Choose your centre stone from 5 to 8 carat. The halo widens the face of the stone so it reads larger than its weight, and the triple pavé carries the sparkle all the way round the finger rather than stopping at the setting.
Every centre stone is graded E colour and VVS2 clarity — colourless, with inclusions that take magnification to find — and comes IGI certified, with the certificate shipped alongside the ring.
Made to order in 18K solid gold: yellow, white or rose. Solid gold throughout, never plated.

Frequently Asked Questions
How much does a large lab-grown diamond ring cost in solid gold?
At The Karat Store this ring runs from $3,899 for a 5 carat up to $7,299 for an 8 carat, all in 18K solid gold, never plated.
Is a lab-grown diamond a real diamond?
Yes. A lab-grown diamond is chemically and physically the same material as a mined diamond, graded on the same scale by the same laboratories. The only difference is how it was formed.
What is triple pavé?
Three rows of small diamonds set side by side along the band, instead of the single row used on a standard pavé ring. It makes the band read wider and brighter, and balances a large centre stone.
Why is this offered only in 18K gold?
At these carat weights the diamond accounts for most of the value, so a lower gold purity saves very little. 18K gives the richest colour and the best setting for a stone of this size.
Can this ring be resized?
Yes. Select your ring size from the dropdown before checkout. If you are unsure of your size, we recommend visiting a local jeweller for an accurate measurement.
