How much does a lab-grown diamond engagement ring cost in Melbourne?

Across Australian jewellers, complete 2 carat rings run about $3,900 to $6,800 and 3 carat rings about $4,700 to $9,000. Our 1 carat , 2 carat and 3 carat price guides name the exact stones behind those figures.

Are lab-grown diamonds real diamonds?

Yes. A lab-grown diamond is carbon with the same crystal structure, hardness and sparkle as a mined diamond. It is grown in a laboratory rather than mined, and graded on the same colour and clarity scales.

Are your lab-grown diamonds certified?

Yes. Every lab-grown diamond we source is IGI certified, in D to F colour and VS1 clarity or better. The report number is inscribed on the stone, so you can check it against the report yourself.

How do I choose my lab-grown diamond from Melbourne?

You choose your setting and metal, then pick your stone from our IGI certified diamonds by carat, colour, clarity and shape, with a 360 degree video of each stone and its report. Or book a free 15 to 30 minute consultation and Brie will help you compare stones. Our guide to choosing your lab-grown diamond covers what to check.

How long does a lab-grown diamond ring take to reach Melbourne?

Your ring takes 4 to 6 weeks to make once you approve the design, then ships free, insured and express to Melbourne, about 6 to 8 weeks from your first conversation to delivery.

What warranty and returns policy do you offer?

Every ring has a lifetime warranty against manufacturing defects. Because every ring is made to order, we do not accept change of mind returns, and cancelling before the design is approved has a $750 fee. If there is a quality problem, tell us within 30 days of delivery and we will put it right. The full details are on our returns page and delivery and warranty page .

Which lab-grown diamond styles are popular in Melbourne?

Oval lab-grown engagement rings are the most requested, followed by lab-grown solitaires . Many Melbourne buyers use the value of lab-grown to choose a larger stone or put more of the budget into the setting.
