How to compare a lab grown diamond

• Start with cut and proportions: light performance usually affects visible sparkle more than a small change in colour or clarity grade.
• Read the complete report: check measurements, table, depth, polish, symmetry and fluorescence—not carat weight alone.
• Balance colour and clarity: an eye-clean diamond can offer better value than paying for differences that are difficult to see.
• Confirm the setting and timeline: our team can help verify fit, production details and current stone availability before you order.

Frequently asked questions

Are lab grown diamonds real diamonds?

Yes. They are diamonds created in a controlled laboratory environment rather than mined from the earth. They are not cubic zirconia, RZ simulant or moissanite.

Can customers in Singapore or Malaysia order online?

Select your destination and local currency, add the chosen item to the cart, then enter the delivery address at checkout to see the delivery methods currently available for that destination. Contact Roselle before payment if you need a fixed arrival date or have questions about insurance, customs duties, taxes or returns.

Do the diamonds have grading reports?

Many stones are supplied with an independent grading report. Check the individual listing and report number before purchase; availability and grading laboratory vary by stone.

Can Roselle make a custom engagement ring?

Yes. Choose a loose diamond and discuss metal, setting style, ring size and production schedule with our jewellery team.
