Absolutely! If you've found a diamond you love, we recommend purchasing it as soon as possible and sharing your order number with us. This allows us to reserve your diamond while we create your custom CAD and 3D design, which typically takes up to 24-48 hours.
Because our inventory is live and in high demand, diamonds can sell quickly. Purchasing your diamond first ensures it is reserved exclusively for you while we complete your custom setting design.

Simply share the SKU or a link to the certified diamond you'd like us to match, and our team will review it and provide you with our best possible price. Read our full Price Match Policy here.
Yes! You can customize the band width of your ring.
Please note that the standard band width depends on the size of the center diamond. If you choose a larger or smaller center stone, our design team will adjust the band width accordingly to ensure the ring remains well-proportioned. For example, a ring with a 1 ct center diamond typically has a band width of 1.80 mm or less.
If you'd like a different band width, simply include your request in the Order Notes section during checkout.
Custom Band Width Pricing:
Please note: Increasing the band width may also increase the ring's total gold weight, which is reflected in the customization cost.

Not at all! This is completely normal.
We partner with 750+ trusted manufacturers and offer an inventory of over 2.5 million certified lab-grown diamonds. Since each manufacturer sets its own pricing, you may find two diamonds with identical specifications listed at different prices.
Rest assured, a lower price does not mean lower quality. The diamonds are independently graded by reputable laboratories, such as IGI, GIA, or GCAL, ensuring they meet the quality stated on their grading reports.
If you're deciding between two similar diamonds, our GIA-trained gemologists are happy to help you compare them and recommend the best value for your budget.
You'll enjoy the same certified diamond, exceptional customer service, and the confidence of shopping with Loose Grown Diamond.
It takes advanced diamond-testing equipment and trained professionals to identify whether a diamond is natural or lab-grown.
Don't worry! Some diamonds may not have a 360° video available because the manufacturer hasn't uploaded one yet.
Simply contact our team, and we'll do our best to obtain a 360° video or a live tweezer/natural light video of the diamond from the manufacturer.
Please note:
If you've found a diamond you love, we recommend placing your order first to reserve it while we request the video. This helps ensure the diamond doesn't sell out before your purchase is complete.
Simply click here to submit your custom design request. To help us get started, please include your ring size, preferred metal, center stone, and any reference images or design ideas.
Your first CAD and 3D design is completely free. If you request additional design revisions that require creating a new CAD model or a completely new setting design, each subsequent CAD design will incur a non-refundable fee of $20.
This fee helps cover the time and resources required to create additional custom designs.
Every certified diamond we sell is accompanied by an independent grading report from IGI, GIA, or GCAL, confirming its quality and unique characteristics.
You can verify that you've received the correct diamond by matching the report details such as the certificate number, carat weight, color, clarity, and measurements. You may also have the diamond inspected by a local jeweler or independent gemologist for additional peace of mind.
Please note: Calibrated, melee and non certified diamonds are not individually certified and therefore do not include a grading report.
Yes! We can request a temporary hold on a diamond with the manufacturer for up to 6 hours. This gives you time to confirm your decision with your partner, family, or friends before completing your purchase.
Holds are processed on a first-come, first-served basis and are subject to the manufacturer's approval.
Please note:
Tip: The best way to guarantee your diamond is reserved is to place your order as soon as possible.
Our calibrated lab-grown diamonds are manufactured to a high level of precision, with a size tolerance of ±0.10 mm. This ensures consistent dimensions, making them ideal for pre-made jewelry settings, repairs, and matching projects.
Please note: A slight variation of up to 0.10 mm is normal and falls within industry standards for calibrated diamonds.
Our standard crafting time is up to 2 weeks for all 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 need your order by a specific date, please contact our customer support team, and we'll do our best to accommodate your request.
The crafting time depends on the shape of the side stones:
Please note: Custom jewelry or designs with specialty side stones may require additional crafting time. If you need your order by a specific date, please contact our customer support team, and we'll do our best to accommodate your request.
The standard crafting time for jewelry featuring treated colored melee diamonds (Blue, Green, Pink, Purple, and Yellow) is typically 2–4 weeks.
Please note: The exact crafting time may vary depending on the color, availability, and complexity of the design. If you need your order by a specific date, please contact our customer support team, and we'll do our best to accommodate your request.
Yes! Once you place your order and your center diamond has been 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 CAD/3D design, ensuring you're completely satisfied before we start crafting your jewelry.
Please note: Custom design requests or multiple design revisions may require additional time.
Yes! Your first CAD/3D design is completely free. We don't charge for creating the initial CAD/3D model of your custom jewelry, and we offer unlimited revisions to that design until you're satisfied.
However, if you decide to change the entire ring setting or request a new CAD/3D design after the initial design has been completed, each additional CAD/3D design will incur a non-refundable fee of $20.
This fee helps cover the time and resources required to create a completely new design.
Yes! If you purchase both a diamond and a setting from Loose Grown Diamond, your diamond will be professionally set by our expert jewelers and shipped to you as a fully assembled, ready-to-wear ring.
Before shipping, every ring undergoes a thorough quality inspection to ensure it meets our high standards of craftsmanship and security.
Yes! You can purchase a setting without a center diamond from Loose Grown Diamond.
If you plan to use your own diamond, please provide us with the diamond's grading certificate (IGI, GIA, or GCAL) or its exact measurements (length × width × depth) before placing your order. This allows our jewelers to craft the setting for a precise and secure fit.
Please note: Since the setting is custom-made specifically for your diamond, orders for settings without a center diamond are final sale and are not eligible for return or exchange.
If you have any questions about compatibility, our customer support team will be happy to assist you before you place your order.
We have intentionally chosen not to certify these pieces, as they are set with high-quality DEF color and VVS/VS clarity lab-grown diamonds, ensuring exceptional brilliance and value.
If you would like your jewelry to be individually certified, we're happy to arrange it upon request. Please contact us before placing your order, and we'll provide you with the available certification options and the associated cost.
Absolutely! We'd be happy to create a custom ring using your existing diamond.
You can choose from our wide selection of ring settings available on our website, or, if you have a specific design in mind, simply share your inspiration with us. Our team will work with you to create a setting that perfectly fits your diamond.
To ensure a precise and secure fit, we'll need your diamond's grading certificate (IGI, GIA, or GCAL) or its exact measurements before we begin.
Please note:
If you have any questions, our customer support team will be happy to guide you through the process.
Yes! We provide a complimentary digital appraisal letter for your purchase.
Simply email us at support@loosegrowndiamond.com with your order number, and our team will send you a fully digital appraisal letter at no additional cost. The appraisal can be used for insurance purposes and includes the relevant details of your purchase.
Yes. Every certified lab-grown diamond is accompanied by an independent grading report from GIA, IGI, or GCAL, detailing the diamond's 4Cs—cut, color, clarity, and carat weight.
If your diamond is mounted in a piece of jewelry, the original laboratory grading report will be included with your order.
Please note:
Please note that GIA, IGI, and GCAL do not assign cut grades to fancy-shaped diamonds (any shape other than round). As a result, fancy shapes such as Oval, Cushion, Emerald, Pear, Marquise, Radiant, Princess, and others will not have an official cut grade listed on our website.
Instead, we recommend evaluating these diamonds based on their proportions, symmetry, polish, and overall appearance, or consulting one of our GIA-trained gemologists for guidance.
Please note: Our inventory is sourced from 750+ trusted manufacturing partners. While we make every effort to ensure the accuracy of our listings, occasional discrepancies may occur. We strongly recommend reviewing the grading certificate before placing your order to verify all diamond specifications.
If you notice any discrepancies after receiving your order, please contact us immediately. We offer a 30-day return policy, allowing you to shop with confidence. After this period, we may not be able to accommodate claims related to listing discrepancies or product specifications.
No. While we manufacture many of our own diamonds and jewelry, we also partner with 750+ trusted manufacturers around the world to offer a wider selection and more competitive pricing.
Every diamond listed on our website meets our quality standards, regardless of whether it is manufactured by Loose Grown Diamond or one of our trusted manufacturing partners.
No. We do not provide ASET images for our diamonds. However, most of our certified diamonds include 360° videos and grading reports to help you evaluate their quality. If you need assistance selecting a diamond, our GIA-trained gemologists are happy to help.
Occasionally, our manufacturing partners may list a diamond with an incorrect price or mark it as available when it is no longer in stock. Since our inventory is sourced from multiple manufacturers, we do not have direct control over these listings.
After you place your order, we contact the manufacturer to secure the diamond. This process can take 24–48 business hours, as many of our manufacturing partners are located overseas.
If the diamond is available, we'll proceed with your order as normal. If it is unavailable or the price has changed, we'll contact you with the following options:
