Is this a real diamond?

Yes — lab grown diamonds are chemically, physically, and optically identical to mined diamonds. Every AlyceJewels diamond is certified by IGI.

What is a lab grown diamond and how is it made?

A lab grown diamond is a real diamond grown using HPHT or CVD — same carbon atoms, same crystal structure, same everything as a mined diamond. The only difference is origin and price.

How does the quality compare to mined diamonds?

Identical grading criteria apply — cut, color, clarity, and carat. Our diamonds are IGI certified with full grading reports.

Is a lab diamond a good investment?

Lab diamonds are best valued for their beauty and ethical sourcing, not resale. The savings vs. mined diamonds mean you get a much larger or higher-quality stone for your budget.

What if the ring doesn't fit?

We offer free resizing within 60 days of purchase. Contact our team and we'll handle everything — no hassle, no charge.

How long does shipping take?

Orders ship within 2–3 business days, fully insured and completely free.

Can I return my order?

Yes. We have a 30-day no-questions-asked return policy. Contact us for a full refund or exchange.

Is AlyceJewels jewelry ethically sourced?

Yes. Lab grown diamonds require no mining — no ecological disruption, no conflict sourcing concerns.

How do I care for my jewelry?

Clean with warm water, mild dish soap, and a soft toothbrush. Store separately to prevent scratching.

Does my jewelry come with a warranty?

Yes — all AlyceJewels pieces come with a 1-year manufacturer's warranty covering craftsmanship defects, plus a complimentary inspection and clean service.

GOOD TO KNOW

Questions, answered.

Everything you need to know before choosing your piece.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are real diamonds with the same fundamental chemical composition and crystal structure as mined diamonds. They are different from diamond simulants such as cubic zirconia and moissanite. The primary difference between a lab-grown and mined diamond is its origin.

Is my diamond certified?

Certification depends on the specific diamond and product purchased. Eligible lab-grown diamonds are accompanied by grading documentation from recognized independent laboratories such as IGI. Please refer to the product specifications for certification details applicable to the piece you're considering, or contact our team before ordering if you'd like confirmation.

How does a lab-grown diamond compare with a mined diamond?

Lab-grown and mined diamonds are evaluated using the same fundamental quality characteristics, including cut, color, clarity, and carat weight. Lab-grown diamonds can offer greater size or quality at a given budget compared with many mined-diamond options, while providing the appearance and properties of a real diamond.

How long will it take to receive my jewelry?

Most Alyce Jewels pieces are made to order. Please allow approximately 10–14 business days for production, followed by approximately 2–3 business days for insured U.S. shipping after dispatch. You'll receive tracking information once your order ships. Customized, engraved, resized, or special-order pieces may require additional time.

Can I return or exchange my order?

Eligible items may be returned or exchanged within 30 days of delivery. Items must meet the conditions of our Returns & Exchanges Policy. Custom-designed, personalized, engraved, modified, final-sale, clearance, or items specifically identified as non-returnable may not be eligible. Contact our team before returning an item so we can confirm eligibility and provide return instructions.

What if my ring doesn't fit?

If your ring doesn't fit as expected, contact our team and we'll help you determine the available resizing options for your specific design. Resizing eligibility can depend on the ring style, setting, size adjustment required, and applicable resizing policy.

Is Alyce Jewels jewelry responsibly sourced?

Alyce Jewels specializes in lab-grown diamonds, which are created in controlled environments rather than extracted through traditional diamond mining. For questions about the sourcing or specifications of a particular piece, please contact our team before purchasing.

How should I care for my jewelry?

For routine at-home cleaning, use warm water, mild soap, and a soft brush, then rinse carefully and dry with a soft, lint-free cloth. Store jewelry separately when possible to help prevent scratching. Certain settings and designs may require additional care, so contact us if you're unsure about the best cleaning method for your piece.
