Gold Buyback: Per Weight vs. Per Piece – Which Pricing Method Is More Advantageous for You? | Gu Jin Jian Bao

There are two pricing methods for old gold Buyback: by weight (how much per gram) and by item (how much per item). In most cases, pricing by weight is more favorable for the seller, but there are a few exceptions—such as branded gold jewelry, limited editions, or antique gold pieces with artistic value. Below, we'll break down the calculation logic and applicable scenarios for both methods.

I. Definitions of the Two Pricing Methods

Method 1: Weight-Based Pricing

The buyback price is calculated based on the purity and weight of the gold jewelry, without considering design, brand, or craftsmanship. Formula:

buyback price = International Gold Price × Purity Ratio × Weight × Merchant Discount Rate

Example: A 30g 999.9‰ pure gold chain, with an international gold price of HK$2,900/gram in 2026. A professional buyback dealer prices it by weight: HK$2,900 × 99.99% × 30g × 98% = HK$85,259.

This is the mainstream market method, covering 90% of old gold Buyback transactions.

Method 2: Item-Based Pricing

The overall value of the gold jewelry is estimated, including the value of the gold itself + design craftsmanship + brand premium + antique value. Formula:

buyback price = Value of Gold Itself + Craftsmanship Premium + Brand Premium + Antique Premium

This method only applies to special gold jewelry with added value (antique gold, branded gold, rare designs).

II. Types of Gold Jewelry Applicable to Weight-Based Pricing

Type 1: Everyday Ordinary Gold Jewelry (80%)

• Unbranded gold chains, bangles, rings
• Plain gold pendants, gold coins without special design
• Broken chains, single earrings, deformed rings, and other damaged gold jewelry
• Ordinary family heirloom gold jewelry

The market value of this type of gold jewelry primarily comes from the gold itself, and buyback dealers do not pay an additional craftsmanship premium. Weight-based pricing is the fairest.

Type 2: Bulk Buyback (>50g)

For large quantities of old gold to be cashed in at once, regardless of the individual design, buyback dealers will price by weight because they will melt it down and sell it to a refinery. The larger the quantity, the more efficient weight-based pricing becomes.

Type 3: Clear Purity Detection (XRF Testing)

professional buyback dealers use XRF non-destructive gold testers to accurately display the gold content (999.9‰, 916.7‰, 750‰, 585‰, etc.). The testing result directly determines the value for weight-based pricing.

III. Types of Gold Jewelry Applicable to Item-Based Pricing

Type 1: International Brand Jewelry (10-30x Premium)

Gold jewelry from international luxury brands such as Cartier, Tiffany & Co., Van Cleef & Arpels, Bulgari, Chopard. Among them:

Example: Cartier LOVE Collection 18K gold bracelet, weighing 30g.

• Weight-based pricing: HK$2,900 × 75% × 30g × 98% = HK$63,945
• Item-based pricing (secondhand market + antique jewelry store): HK$95,000-150,000
• Item-based pricing yields HK$31,055-86,055 more than weight-based.

Type 2: Antique Gold Pieces (5-100x Premium)

Antique gold pieces from before the Qing Dynasty, including:

• Ming and Qing dynasty imperial goldware (gold locks, bangles, hair ornaments)
• Handcrafted gold jewelry from the Republican era
• Hong Kong 1950s-1970s traditional craftsmanship gold jewelry

The antique value of these gold pieces far exceeds the value of the gold itself. Example: Qing Dynasty gold lock (weighing 80g, pure gold):

• Weight-based pricing: HK$2,900 × 99.99% × 80g × 98% = HK$227,344
• Estimated by antique auction houses: HK$500,000-2,000,000+ (based on design craftsmanship, preservation status, provenance)

Type 3: Commemorative Gold Jewelry (10-50% Premium)

Gold jewelry with historical commemorative significance, including:

• 1997 Hong Kong Handover commemorative gold medals
• Olympic commemorative gold coins
• Millennium commemorative gold bars
• Celebrity-signed gold jewelry

This type of gold jewelry has an additional premium in collecting circles, but requires original packaging and certificates.

Type 4: Gem-Set Gold Jewelry

Gold jewelry containing precious stones such as diamonds, rubies, sapphires. The value of the gemstones may far exceed that of the gold itself. Example: 18K gold ring set with a 1-carat D color VS1 diamond:

• Value of gold itself (based on 5g 18K): HK$10,663
• Value of diamond (based on GIA certificate): HK$45,000-65,000
• Total value: HK$55,663-75,663
• Item-based pricing can reflect the value of the gemstones, while weight-based pricing would be wasteful.

IV. Four Dimensions for In-depth Comparison

V. How to Determine Which Pricing Method Your Gold Jewelry Should Use?

Decision Process

1. Does it have a brand mark?
   • Has an international brand (Cartier, Tiffany, etc.) → Item-based may be more advantageous, go to an antique jewelry store or auction house
   • No brand or only local jewelry store mark → By weight
2. Does it have historical significance?
   • Pre-Qing Dynasty → By item (auction house special session)
   • Handcrafted from the Republican era to the 1970s → Item-based may have a premium (antique jewelry store)
   • Modern craftsmanship after 1980 → By weight
3. Is it gem-set?
   • Contains valuable gemstones (diamonds, rubies, sapphires, emeralds) → By item (jewelry store)
   • No gemstones or only semi-precious stones (cubic zirconia, synthetic stones) → By weight
4. Is it commemorative?
   • Commemorative gold jewelry with original box and certificate → Can try item-based
   • Ordinary gold jewelry → By weight

VI. Practical Case Studies Comparison

Case 1: Mrs. W's Ordinary Gold Chain

• Item: A 30g pure gold chain purchased from a local jewelry store, no special design
• Weight-based pricing: HK$85,259
• Attempted item-based pricing (antique jewelry store): HK$78,000-82,000 (item-based was actually lower)
• Conclusion: Weight-based is most advantageous

Case 2: Mr. L's Cartier Bracelet

• Item: Cartier LOVE 18K gold bracelet, weighing 30g, with original box
• Weight-based pricing: HK$63,945
• Item-based pricing (antique jewelry store): HK$120,000-150,000
• Conclusion: Item-based yields HK$56,055-86,055 more

Case 3: Mrs. Chan's Traditional Plain Bangle (Non-Branded)

• Item: Traditional plain bangle purchased from a local gold shop, weighing 50g of pure gold
• Weight-based pricing: HK$142,098
• Attempted item-based pricing: HK$135,000-145,000 (no brand, no antique value)
• Conclusion: Weight-based is most advantageous (traditional craftsmanship premium is paid only at purchase, not recouped at Buyback)
