Our rings come standard with lab-grown diamonds. If you prefer to use natural diamonds or gemstones in your ring. Please get in touch with us, and we can provide pricing.
What affects the price of an engagement ring?
The price of an engagement ring depends on the setting style, metal, centre stone, diamond size, diamond quality, and whether you choose a lab-grown diamond, natural diamond, or gemstone. Lab-grown diamonds are often a great option for customers looking for a larger or higher-quality centre stone at a lower price than a comparable natural diamond. Our ring builder lets you compare settings and stones so you can create a ring that fits your style and budget.
What if I don't see the ring I want? Can I customize?
Certainly! We are expert makers of custom engagement rings. We can modify any style you see or create something from scratch. Book an appointment to discuss in more detail.
Does the engagement ring come with certification?
Yes, our engagement rings and jewellery come with an independent appraisal.
The appraisal will confirm the materials in the ring and include your name and retail value. Lab-Grown Diamonds come with a GIA or IGI certificate, and natural mined diamonds come with a GIA certificate.
The diamond grading report numbers are laser etched onto the girdle of each diamond.
