Buying a diamond for a ring or gift? Start with your budget, compare the individual stones, and check the report and purchase terms before ordering.
Use the live lab-grown diamond price guide to see current listed prices by carat. These are Veyara inventory prices, not a market-wide valuation. For a ring, reserve part of your budget for the setting, setting work and applicable taxes before choosing the loose stone.
Compare a few stones with similar weight, shape, color, clarity and laboratory information. Then review their measurements, report details and available video: matching grades do not guarantee matching appearance. Browse 2–3 carat rounds, explore larger oval diamonds, or request three options for your budget.
The basicsA lab-grown diamond has the same basic chemical composition and crystal structure as a mined diamond, but it forms in a laboratory rather than underground. CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) are the two principal growth methods. Gemological laboratories can identify laboratory-grown diamonds and distinguish them from mined diamonds.
Both processes grow crystallized carbon with diamond's characteristic hardness and optical properties. Lab-grown diamonds are not simulants such as cubic zirconia; their laboratory origin is the important distinction.
CVD growth begins with a thin seed — a small slice of existing diamond. The seed is placed inside a sealed reactor, which is then filled with a carbon-rich gas, usually methane. The gas is energized into a plasma using microwave or filament heating, which breaks the methane molecules apart and allows carbon atoms to settle onto the seed.
Layer by layer, atom by atom, a new diamond grows. Over several weeks, what starts as a tiny seed becomes a rough crystal large enough to cut into a polished gemstone. From there, the rough is planned, cut, and polished exactly the way a mined rough would be.

Weight, not size. One carat equals 0.2 grams. Two stones of the same carat weight can look different sizes depending on how they're cut.
Where a report uses the D–Z scale, D means colorless and color becomes more noticeable toward Z. Check the actual report format and compare the stone in the metal color you intend to use.
Clarity describes internal inclusions and surface blemishes. Reports that use the traditional clarity scale run from FL (flawless) to I (included). The grade alone does not establish whether you will notice an inclusion without magnification; review the individual stone.
Cut describes how a diamond interacts with light, not just its outline or shape. Review the laboratory’s cut assessment where provided, proportions and available stone video. Polish and symmetry are separate assessments; neither alone establishes an overall cut grade. See GIA’s guide to diamond cut.
Some listed stones have third-party grading reports from laboratories such as IGI or GIA. When available, a report can document the 4Cs, measurements, polish, symmetry, treatments, and laboratory-grown identification. Check the current listing for the report and media available for that specific stone.
Report formats differ by laboratory and service. GIA’s current assessment for colorless to near-colorless laboratory-grown diamonds uses Premium or Standard categories. Older reports and other laboratories may show individual grades. Read the document for the specific stone rather than assuming all reports use the same scale.
A listing without a third-party report relies on the specifications supplied for that item. Review the current listing and ask questions before ordering rather than assuming certification is included.
For independent guidance and report lookup, consult the FTC Jewelry Guides, GIA's laboratory-grown diamond services and information, and IGI Report Check. These official-resource links do not imply affiliation, endorsement, or membership.
Buying separately lets you compare loose stones and choose a setting independently. Before ordering, ask your jeweler to confirm the stone’s measurements will fit the setting and quote the work, timing and responsibility for damage during setting. Compare that complete quote with a finished ring; buying separately does not guarantee a lower total. Our DIY ring guide explains the planning steps, and the finished ring collection offers another route.
Memo review is not automatic. It is available only when approved in written terms for a specific order.
Yes. Browse the public loose-diamond inventory to compare individual stones and their listed prices. For help narrowing the options, send your budget and preferences.
Start with the live price guide, then compare individual listings in your range. The loose-stone price is not a finished-ring quote: allow for the setting, setting work and applicable taxes.
The stone page shows the laboratory, report number and links recorded for that listing. Use the issuing laboratory’s official report-check service to compare its record with the listing. A link to a lookup service does not mean a report match has already been verified. Ask about missing or inconsistent details before ordering.
Inventory can include CVD or HPHT stones. Review the growth-method information shown on the current listing when it is available.
Compare measurements, proportions, the report and any available exact-stone media alongside price. Similar carat weight and grades can still produce different appearances. Ask for clarification if media is missing or identified as a reference image.
Confirm the dimensions with your jeweler, obtain a setting quote and review the stone’s report, media and purchase terms. Choose the appearance and total cost that work for you rather than assuming the largest stone or highest grade is the best choice.
Review the current shipping and return terms and the specific product page before ordering. Finished jewelry has production time and final-sale terms that differ from loose stones. Confirm timing with our team if you have a proposal or gift deadline.
