If I order a diamond and a setting from Kleora Diamond, will it arrive as a complete ring?
Yes! If you purchase both a diamond and a setting from Kleora Diamond, our expert jewelers will professionally set the diamond and ship your ring fully assembled and ready to wear.
Before shipping, every piece undergoes a careful quality inspection to ensure the setting is secure and the craftsmanship meets our standards.
Can I see the CAD/3D design of my ring or jewelry before it's made?
Yes! Once your order is placed and your center diamond is secured, we’ll create a CAD/3D design of your ring or jewelry and email it to you within 48 business hours for your review and approval.
Production will begin only after you approve the design, so you can feel confident about the final look before we start crafting your piece.
Please note: Custom designs and multiple revisions may require additional time.
What is the crafting time for rings and fine jewelry?
Our standard crafting time is up to 2 weeks for rings and fine jewelry before shipment.
If you select Express Shipping, your order may be prioritized, which can help reduce the overall delivery time.
Please note: Crafting times may vary depending on the design, customization, and order volume. If you have a specific delivery date in mind, please contact our support team, and we’ll do our best to accommodate your request.
Do you offer free resizing for all your rings?
Yes! We offer one complimentary ring resize within 30 days of delivery on eligible rings.
To request a resize, simply contact our support team through live chat or email us at support@kleoradiamond.com. Please have your order number and desired ring size ready so we can assist you quickly.
Please note: Certain wedding bands cannot be resized and are not covered under this policy.
What's the band width of the ring? Can I change it?
Yes! You can customize the band width of your ring to suit your style.
The standard width is based on the center diamond size, and our design team adjusts it to keep the ring balanced and well-proportioned. For example, a 1 ct center diamond typically has a band width of 1.80 mm or less.
If you’d like a specific width, simply add your request in the Order Notes at checkout.
Custom Band Width Pricing:
- Up to 1.80 mm: Complimentary
- Up to 2.00 mm: +$100
- Up to 2.20 mm: +$200
- Up to 2.40 mm: +$400
- Above 2.40 mm: Contact support@kleoradiamond.com for a custom quote.
Please note: A wider band may require additional gold, which is reflected in the customization cost.
Can I buy a setting without a diamond from Kleora Diamond?
Yes! You can purchase a setting without a center diamond from Kleora Diamond.
If you plan to use your own diamond, please provide its IGI, GIA, or GCAL grading report or the exact measurements (length × width × depth) before placing your order. This helps our jewelers create a precise and secure setting for your diamond.
Please note: Settings made specifically for your diamond are final sale and are not eligible for return or exchange.
If you’re unsure about compatibility, our customer support team will be happy to assist you before you place your order.
