Choose lab-grown diamond jewelry by identity, specification and the finished piece.
A lab-grown diamond purchase should start with clear disclosure of what the stone is, then move to the same practical questions that shape any finished piece: appearance, dimensions, clarity, setting, material, price and documentation. New to the category? Read the lab-grown diamond overview first. This guide separates those decisions so you can compare products without relying on a single marketing phrase.
Belaroq catalog snapshot
Active inventory as of 2026-09-30. This is a Belaroq catalog snapshot of finished jewelry, not market-wide loose-diamond price research.

Data source, calculation and limitations
One listed starting price (estimatedPrice in USD) per active inventory design. Prices above zero enter price statistics; unpriced designs remain in product counts. Metal and stone configuration are not held constant between designs. Tax, destination duties and shipping are not included in these comparisons.
Sort prices ascending and interpolate at position (sample size − 1) × percentile; round the result to two decimal places. P25–P75 contains the middle half of the sample.
Pair the positive VS and VVS priceOptions for the same SKU; compute (VVS − VS) / VS × 100 before calculating percentiles. Examples select the median-priced VS design in each category; they are not customer purchases.
totalCarat is the combined catalog weight for the finished piece, not a guaranteed center-stone weight. Missing and non-positive weights are excluded from carat bands.

Confirm identity before comparing quality
Laboratory-grown diamonds share core chemical and optical properties with natural diamonds, so reliable origin identification requires appropriate gemological testing rather than visual inspection alone.
A grading or identification report should state that the diamond is laboratory-grown. Do not confuse a laboratory-grown diamond with simulants such as cubic zirconia or moissanite.
Read the report as a specification record
Depending on the report type and whether the stone is loose or mounted, documentation may cover identity, shape, measurements, carat, color or quality category, clarity, finish, growth method, treatments and inscription details.
Match the report number and description to the piece you receive. For mounted jewelry, some assessments may be limited by the setting, so read exactly what the report covers.
Compare the finished piece, not only the stone
A well-chosen diamond can still be presented in very different ways. Review metal, setting security, stone count, total carat, dimensions and how the piece will be worn, and let the diamond shape guide settle the silhouette first.
Carat measures weight, while dimensions help explain visible scale. Clarity is graded under magnification, while cut and proportions strongly influence how the stone handles light, and how diamond clarity is graded decides which grade is worth paying for.
Make the order specification explicit
Before production, confirm the exact clarity option, ring size when relevant, material, certificate preference, price and any custom changes, and benchmark the price against the lab-grown diamond price guide. The order record should preserve those decisions.
Belaroq product pages store the selected VS or VVS option and ring size with the cart and order. Final physical dimensions remain subject to the confirmed production specification.

The practical takeaway
Verify laboratory-grown identity, read what the report actually covers, compare the whole piece and keep every production choice in the order record. Then apply the same checklist while browsing the full product catalog.
