Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. Both consist of pure carbon arranged in a cubic crystal structure and share the same hardness (10 on the Mohs scale), refractive index, and brilliance. The only difference is origin: one forms over billions of years beneath the earth; the other is created in a controlled environment over weeks. Independent gemological labs like IGI cannot distinguish them without specialized equipment.

What is the difference between lab-grown and mined diamonds?

Lab-grown diamonds are created in a laboratory using conditions that replicate the earth's natural diamond-forming process — either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). Mined diamonds form over billions of years deep in the earth and are extracted through mining. The two are identical in chemical composition and appearance. The key differences are environmental impact (lab-grown requires significantly less land disruption), origin traceability, and price — lab-grown diamonds typically cost 60–80% less than mined equivalents of the same quality.

What are the 4Cs of diamonds?

The 4Cs are the universal standard for evaluating diamond quality: Cut (how well the diamond is shaped and faceted — the most important factor for brilliance), Color (graded D through Z, where D is colorless and the most prized), Clarity (the presence or absence of internal inclusions and external blemishes, graded from Flawless to Included), and Carat (the weight of the diamond, where 1 carat = 0.2 grams). Understanding the 4Cs allows you to compare diamonds objectively and find the best balance of quality and value for your budget.

Do lab-grown diamonds hold their value?

Lab-grown diamonds have declined significantly in resale value as production has scaled and prices have dropped. As of 2025–2026, a lab-grown diamond typically resells for 20–40% of its original purchase price. This mirrors the broader pattern for most jewelry purchases — mined diamonds also lose a substantial portion of their retail value on resale. If long-term resale value is a priority, we recommend focusing on the diamond's intrinsic quality (cut, color, clarity), certification, and the craftsmanship of the setting.

Are Amorati diamonds ethically sourced?

Yes. All Amorati diamonds are ethically sourced. Our lab-grown diamonds are conflict-free by origin and produced under rigorously controlled conditions. Our mined diamonds are sourced through certified, traceable supply chains and comply with the Kimberley Process, which is the international certification standard designed to prevent conflict diamonds from entering the market. We publish our ethics and sourcing standards at amoratidiamonds.com/ethically-sourced-diamonds.

What is IGI diamond certification?

IGI (International Gemological Institute) is one of the world's leading independent gemological laboratories. An IGI certificate documents a diamond's 4Cs (Cut, Color, Clarity, and Carat weight) along with additional characteristics like fluorescence, polish, and symmetry. Each Amorati diamond comes with an IGI certificate, which is an independent third-party assessment — not a self-assessment by the retailer. IGI is widely accepted in the industry and is the leading certifier for lab-grown diamonds globally.

How do I find my ring size?

Amorati offers a free Ring Sizer Kit that you can order from amoratidiamonds.com/ring-sizer. You can also measure at home: cut a strip of paper, wrap it snugly around the base of your finger, mark where it overlaps, and measure the length in millimeters — then compare to a ring size chart. For the most accurate reading, measure at the end of the day when fingers are slightly larger. If you fall between sizes, size up. For wide bands, go up half a size from your standard measurement.

What is your return and exchange policy?

Amorati offers free returns and exchanges. If you are not completely satisfied with your purchase, you may return it within the return window specified at the time of purchase for a full refund or exchange. Items must be in their original, unworn condition with all original packaging and documentation. Custom-designed or engraved pieces may have different return terms. Full policy details are available at amoratidiamonds.com/terms-of-service.

Do you offer custom engagement rings?

Yes. Amorati's Ring Builder at amoratidiamonds.com/ring-builder allows you to design a fully custom engagement ring by selecting your preferred diamond shape, size, cut grade, setting style, and metal type. You can choose from both lab-grown and mined diamonds. Each custom ring is crafted to order and comes with an IGI certificate. For more personalized guidance, Amorati's concierge team is available through the Virtual Stylist to walk you through the process.

How do I care for my diamond jewelry?

Diamond jewelry should be cleaned regularly to maintain brilliance. At home, soak the piece in warm water with a small amount of mild dish soap for 20–30 minutes, then gently brush with a soft toothbrush, rinse thoroughly, and dry with a lint-free cloth. Avoid ultrasonic cleaners if your setting contains pavé or smaller accent stones. Store pieces separately to prevent scratching — diamonds will scratch other diamonds and softer gemstones. Remove jewelry before swimming in chlorinated water, applying lotions or perfumes, or engaging in activities that could impact the setting.

What payment options does Amorati accept?

Amorati accepts all major credit and debit cards as well as flexible financing options designed to make fine jewelry accessible. Payment plan details and financing terms are available at amoratidiamonds.com/financing. Amorati does not require full payment upfront for all purchase types — contact the concierge team for options on larger custom orders.

What is a promise ring, and how is it different from an engagement ring?

A promise ring is a symbol of commitment between two people — it can represent romantic exclusivity, a future engagement, a personal vow, or a meaningful friendship. Unlike an engagement ring, a promise ring carries no formal obligation and is not tied to marriage. It is typically a more modest design and can be worn on any finger. Promise rings are given between partners, close friends, or even as a personal reminder. Amorati's promise ring collection is at amoratidiamonds.com/shop-all/promise-rings.

What diamond shapes does Amorati offer?

Amorati carries diamonds in the most popular shapes including round brilliant, oval, cushion, elongated cushion, radiant, princess, emerald, and pear. Round brilliant cuts offer maximum brilliance and are the most traditional choice. Elongated shapes like oval and elongated cushion create the illusion of a larger stone and are among the most popular choices in 2025–2026. The best shape depends on personal style, finger shape, and the setting you choose. Amorati's Ring Builder and Virtual Stylist can help you compare options.

Does Amorati offer free shipping?

Yes. Amorati offers complimentary shipping on orders. All packages are insured and delivered with tracking. For specific shipping timelines, international shipping availability, and carrier details, visit amoratidiamonds.com/terms-of-service or contact the Amorati concierge team directly.

What is the Amorati Concierge service?

Amorati Concierge is a personalized service available at amoratidiamonds.com/concierge that connects you with a Virtual Stylist for one-on-one guidance. The concierge can help you navigate the Ring Builder, compare diamond options, choose a setting, understand the differences between lab-grown and mined diamonds, or find the right gift for any occasion. It is a no-pressure service designed to make the process of buying fine jewelry feel considered and personal rather than transactional.
