Yes — every diamond we sell comes with a GIA (Gemological Institute of America) grading report. This report independently verifies the carat, cut, color, clarity, polish, symmetry, fluorescence, and measurements of each stone. We never sell uncertified diamonds.

Triple Excellent (3EX) refers to a diamond that has received Excellent grades for Cut, Polish, and Symmetry from the GIA. These three grades together determine how precisely a diamond was faceted and finished. A Triple Excellent stone reflects light at maximum efficiency — it’s the highest standard in the industry.

Yes — we carry both natural and lab-grown diamonds, all GIA- or IGI-certified to the same Triple Excellent cut standard. Lab-grown stones are optically and chemically identical to natural diamonds, at a meaningful price advantage. If you have a specific stone in mind, contact us and we’ll help you choose.

Your GIA report includes the diamond’s shape, measurements, carat weight, color grade (D–Z), clarity grade (FL–I3), cut grade, polish, symmetry, and fluorescence. The report also includes a unique certificate number you can verify at gia.edu. We’re happy to walk you through it — just contact us.

We focus on D–H color and VS2 or better clarity — the range where a diamond is eye-clean and colorless or near-colorless to the naked eye. This gives you the best combination of quality and value.

We accept all major credit and debit cards (Visa, Mastercard, Amex, Discover) through Shopify Payments, plus Apple Pay, Google Pay, Shop Pay, PayPal, and Venmo. All transactions are encrypted and processed securely.

Yes. Our Ring Builder lets you select a diamond and choose a setting style, metal, and band design. If you have a specific custom design in mind that isn’t in our builder, contact us and we’ll discuss options.

Yes — we offer Shop Pay Installments and PayPal Pay Later at checkout. Split eligible orders into 4 interest-free payments, or choose monthly installments for larger purchases — any rate is shown before you confirm, with no hidden fees.

Contact us and we’ll do our best to hold a stone for up to 48 hours while you decide. Our inventory is live and stones can sell, so we can’t guarantee holds for longer periods.

Every Tessera piece is made to order with certified diamonds sourced to your specifications. Please allow 4–6 weeks from order confirmation for production and delivery. You’ll receive an email with tracking when your order ships.

Yes. Every shipment is fully insured for the purchase value and requires a signature upon delivery. We do not leave packages unattended.

No — we ship within the United States only. We do not ship outside the US.

Your diamond or ring arrives in our signature black and gold presentation box, packed in a protective outer carton. We take packaging seriously — your order should feel like a gift the moment you open it.

We offer a 30-day return window that starts the day your order is delivered — not the day it ships, so a slow delivery never eats into your window. Return shipping is free and fully insured, with no annual cap on how many returns you make. Items must be returned in original condition, unworn and unaltered, with the original grading report. Custom orders are final sale. See our full Shipping & Returns policy for details.

Visit our Returns Portal to start in under 2 minutes — sign in to your account or email us with your order number. We send a prepaid, fully-insured return label within one business day.

All jewelry purchased from Tessera Diamonds comes with a lifetime warranty against manufacturing defects. This covers issues with settings, prongs, and construction — not normal wear, accidental damage, or lost stones. We recommend periodic professional inspection for prong integrity.

Contact us within 48 hours of delivery with photos of the damage. We’ll arrange an immediate replacement or full refund. Damage during shipping is covered under our insurance.

Start by choosing your diamond — filter by shape, carat, cut, color, and clarity. Then select a setting style and metal (platinum, white gold, yellow gold, or rose gold). You’ll see a live preview before adding to cart. If you’d like help at any step, we’re available by phone or email.
