Quality Inspection
Every diamond is hand-inspected under a 10x loupe and microscope by RockHer gemologists before shipment. We verify the IGI certificate matches the stone, confirm the laser inscription on the girdle, and check for any damage or quality variance. If a stone does not meet our standard, it is rejected — not shipped.
Shipping & Lead Time
Ships from our Los Angeles atelier within 8 to 12 business days of order. Free overnight FedEx shipping, fully insured, signature required at delivery. Tracking provided.
How Selection Works
This product represents the spec, not a single specific stone. After you order, our gemologist selects an available diamond from current inventory that meets all listed specifications. Your IGI certificate number and exact carat weight are confirmed before shipment. Want to see specific available stones first? Contact our atelier — we can share current inventory matching your spec.
Setting & Pairing
This listing is the loose diamond only. Settings are sold separately. Browse our engagement ring settings to pair, or have us set it in any piece sourced elsewhere — our atelier handles custom mounting.
Returns & Verification
40-day returns in original condition with all documentation. Every IGI certificate is publicly verifiable at igi.org/verify-your-report using the report number on your certificate.
Common Questions
Is this a finished ring? No. This is the loose diamond only. The setting is purchased separately.
Will I know which specific stone I am receiving? Yes. Once your stone is selected, you receive its unique IGI certificate number, exact carat weight, and measurements before shipment.
Is the certification real? Yes. Every diamond is graded by IGI, an independent third-party gemological laboratory. Verify your report at igi.org.
What is the difference between lab grown and natural? Lab grown diamonds have the same physical, chemical, and optical properties as natural diamonds. They are real diamonds, grown in a controlled environment rather than mined.
Can I see the diamond before it ships? Yes. Once your stone is selected, we send the IGI certificate and high-resolution images for your review before final shipment.
What if the diamond is not what I expected? Return it within 40 days for a full refund. We pay return shipping. No questions asked.
