Quick recommendations
Separate the measurements
Record centre-stone and combined diamond weights separately; they describe different things.
Match the record

Search with a brief
Choose the jewellery category on ALVAU with a reference, form, metal and documentation brief.
What matters before you choose
For an important centre stone, obtain specific quality information rather than a broad advertised range. GIA’s guidance distinguishes carat, colour, clarity and cut and explains that shape and cut are different concepts. Its conventional round-brilliant cut grade should not be assumed for every fancy shape. Compare the actual diamond in several lighting conditions where practical, and use a qualified professional when the purchase requires assessment beyond the available photographs and report.
Keep gemstone documentation within its proper scope. GIA Report Check confirms that report information matches its database. That is a useful record check; the physical stone still needs to match the document. GIA explicitly states that its reports are not valuations, appraisals or guarantees. A jeweller should also assess the setting, wear and repairs. Do not use a central-stone report to assume the identity of all accent stones or the authenticity of the entire branded item.
Ask whether diamonds are natural or laboratory-grown and read the document actually supplied. Report formats and dates matter: GIA’s current service for colourless to near-colourless laboratory-grown diamonds uses Premium or Standard quality assessments, while historical reports may use another format. Make the material disclosure clear before comparing offers. For coloured gemstones in a mixed design, request relevant identification and treatment information rather than extending diamond assumptions to every stone.

 | The Tiffany Setting Engagement Ring in Platinum is a round-brilliant solitaire held by six prongs. It gives a concrete reference for a buyer who wants a single centre stone and a clearly defined engagement-ring silhouette.

It is a useful alternative when warm metal and a different prong arrangement fit the wearer’s preference. The official model uses a natural round diamond, but an actual seller’s item still needs its own matching evidence. | Judge the specific stone and prong condition; neither a brand description nor a familiar photograph identifies the diamond being offered. |
 | Bvlgari Serpenti Viper Ring 349740 is an 18 kt white-gold wedding band with full pavé diamonds. It makes sense to compare when the desired effect comes from a patterned ring surface rather than one raised centre stone. Evaluate the complete band on the finger and look closely at the continuity of its settings. | Inspect all pavé areas for stone condition and repairs. An attractive overall image can hide details along the edges and underside. |
 | Tiffany T T1 Bangle in white gold with baguette and pavé diamonds combines distinct diamond arrangements in a graphic wrist design. Use selected medium reference 73586151 to identify the documented version. It offers a different route from a ring when the occasion calls for a visible wrist piece and the wearer already enjoys bangles. | Confirm the exact size and SKU; combined diamond weight across the bangle is not comparable to the same weight in a solitaire. |
 | Van Cleef & Arpels Frivole earrings, small model VCARB65800, use diamond-paved flower forms in white gold. They are a relevant comparison when the emphasis belongs near the face.

Two alternatives, compared
Tiffany Setting platinum solitaire versus DB Classic R102254
Tiffany’s six-prong platinum reference and De Beers’ four-prong yellow-gold reference offer different mounting and metal choices for a round centre diamond. Compare the wearer’s preferred metal, the actual setting height and the view of the diamond on the hand. Then compare the specific stone records and return terms. The number of prongs is a design distinction; it does not, by itself, prove one ring’s present condition or establish a universal quality winner.
Serpenti Viper pavé ring versus Tiffany T1 diamond bangle
Both create an effect with multiple diamonds, but the Serpenti reference concentrates it around a finger while T1 creates a broader wrist statement with baguette and pavé arrangements. Compare fit, intended use and the full cost of maintaining the offered piece. If a single-centre diamond is the priority, neither is a direct substitute for a solitaire. If distributed sparkle is the priority, judge the complete design rather than ranking the combined carat figures alone.
What to check before buying
- Request the exact model reference, material disclosure, size and complete condition description. For a centre-stone purchase, ask for specific quality details and the report number rather than an undifferentiated certificate photograph.
- Agree how inspection and stone-to-document matching will take place before payment. Where remote buying makes this difficult, clarify the inspection and return window, the responsible professional and who pays associated costs.
Common mistakes
- Equating a total diamond weight with the size or quality of a centre stone. Different jewellery forms distribute stones differently; compare like constructions before using weight as a decision factor.
- Using a grading record as a resale guarantee. Decide whether the item suits the wearer and budget without assuming future appreciation. Documentation and current condition support a purchase decision; neither promises a financial outcome.
Your questions, answered
Is diamond shape the same as cut quality?
No. Shape describes the outline; cut quality concerns how the cutting works. Read the applicable report fields and do not assume the round-brilliant cut-grade framework covers every shape.
What does GIA Report Check establish?
It checks report information against GIA’s database. Matching the actual stone to that record, and assessing the branded mounting and present condition, remain separate tasks.
Is a diamond report an appraisal?
GIA states that its reports are not valuations or appraisals. If you need a monetary appraisal for a particular purpose, commission the appropriate professional assessment separately.
Should I choose natural or laboratory-grown diamonds?
Choose after clear material disclosure and comparison of the actual design, documentation and budget. Check the report’s issue date and format, and make no assumption about future resale value.
How do I begin on ALVAU?
Choose the jewellery category and start with the specific model or jewellery form. Ask about the actual stone, size, evidence and seller’s terms before treating an offer as comparable.
