About Lab Grown Diamonds
Yes, absolutely. Lab grown diamonds are 100% real diamonds with identical physical, chemical, and optical properties to mined diamonds. They're made of pure crystallized carbon, scored 10 on the Mohs hardness scale, and are graded using the same 4Cs standards. The only difference is their origin—one was formed in the earth over millions of years, the other was created in a laboratory over weeks.
Not without specialized equipment. Lab grown and mined diamonds are optically identical—even trained gemologists cannot distinguish them with the naked eye or standard jeweler's tools. Specialized spectroscopic equipment is needed to detect the subtle growth patterns that indicate laboratory origin. All our diamonds are laser-inscribed on the girdle with their certificate number for identification.
Lab grown diamonds are created using two main methods:
HPHT (High-Pressure High-Temperature): Mimics natural diamond formation by exposing carbon to extreme heat (~1,500°C) and pressure (1.5 million PSI).
CVD (Chemical Vapor Deposition): Builds diamonds layer-by-layer by introducing carbon-rich gas into a chamber with a diamond seed.
Both methods produce genuine diamonds with identical properties to mined stones.
Lab grown diamonds are real diamonds (pure carbon, 10 Mohs hardness)—identical to mined diamonds in every measurable way.
Moissanite is silicon carbide—a different mineral entirely with different optical properties (more fire, different brilliance).
Cubic zirconia is a synthetic material (zirconium dioxide)—a diamond simulant that looks similar but has completely different properties.
Like all diamond jewellery, lab grown diamonds are primarily purchased for their beauty and significance rather than investment value. While mined diamonds also depreciate once purchased, lab grown diamonds offer 40-70% savings upfront—allowing you to get a larger or higher-quality stone. The value is in what they represent and the joy they bring, not resale potential.
Shopping & Orders
Yes. All our diamonds come with certification from leading gemological laboratories, primarily IGI (International Gemological Institute). Certificates detail the diamond's 4Cs (cut, color, clarity, carat), measurements, and confirm its lab grown origin. Digital certificates are provided with every purchase.
Visit our Ring Size Guide for detailed measurement instructions. You can measure an existing ring that fits, use string or paper to measure your finger, or visit a local jeweler. We recommend measuring at the end of the day when fingers are slightly larger. If between sizes, size up. We also offer complimentary resizing within 6 months of purchase.
Yes! We offer customization on many pieces. Contact our team to discuss your vision—whether it's modifying an existing design, creating something completely bespoke, or setting your own diamond. Custom orders typically take 4-6 weeks.
Ready-to-ship items: 5-7 business days within Australia.
Made-to-order rings: 2-3 weeks plus shipping.
Custom designs: 4-6 weeks plus shipping.
Express shipping and international delivery available at checkout.
Yes. All orders are fully insured during transit. We ship via secure courier with signature required, discreet packaging, and real-time tracking. If anything happens during shipping, you're fully covered.
Returns & Warranty
30-Day Returns: Unworn items in original condition can be returned within 30 days for a full refund.
Conditions: Item must be unworn, undamaged, with all original packaging and documentation.
Non-returnable: Custom/bespoke pieces, resized rings, engraved items.
Process: Contact our team to initiate a return. We'll provide a prepaid shipping label for Australian returns.
Garantie à vie couvre les défauts de fabrication sur toutes les créations Caratoir.
Covered: Prong repair, rhodium replating, structural defects, loose stones (from setting issues).
Not covered: Normal wear, damage from accidents or misuse, loss, theft, damage from third-party repairs.
Yes. Within 30 days of delivery, you can exchange for a different size or style. Contact our team to arrange. For ring resizing specifically, we offer complimentary resizing within 6 months of purchase (excludes eternity bands and certain styles).
Daily care: Remove when applying lotions, cleaning, exercising.
Cleaning: Warm water, mild dish soap, soft brush. Professional cleaning recommended annually.
Storage: Separate compartments to prevent scratching. Original box ideal.
Inspections: Check prongs periodically. Annual professional inspection recommended.
Ethical & Environmental
Yes, 100%. Lab grown diamonds have no connection to mining operations and therefore no risk of conflict sourcing. While the Kimberley Process addresses blood diamonds, lab grown diamonds bypass the entire issue by being created in controlled laboratory environments with transparent supply chains.
Significantly more so than mined diamonds. Diamond mining requires moving massive amounts of earth, uses extensive water and energy, and can cause habitat destruction. Lab creation uses considerably less resources with no earth displacement. Many labs (including our partners) are transitioning to renewable energy sources. While not zero-impact, the environmental footprint is substantially smaller.
We source from certified laboratories in USA, India, and South-East Asia that meet strict quality and ethical standards. All partner labs are audited for working conditions and environmental practices. Each diamond is traceable through its certification.
We use recycled precious metals wherever possible. Our gold and platinum are sourced from refineries committed to responsible practices. We're working toward 100% recycled metals across all collections.
