Summary

This report has been prepared following a request to confirm the authenticity of a bag from the brand Gucci X Balenciaga, model Hourglass Hacker Aria Supreme in canvas with GG logo. This limited edition bag is considered one of the most sought-after on the market. After a series of comprehensive tests and analyses, we are able to confirm its authenticity beyond any doubt. Here are the details of the methods used and the results obtained.

Introduction

The authentication of luxury items is a critical task that requires a multidisciplinary approach and advanced scientific methods. In this case, we employed a combination of physical, chemical, and documentary methods to verify the authenticity of the bag in question.

Methods

1. Physical Examination

1.1 Visual Analysis: Thorough observation of the materials, craftsmanship, and details of the bag, including symmetry, stitching, logo, zippers, and buttons.

1.2 Microscopy: Use of a scanning electron microscope (SEM) to examine the fibres of the canvas and the other constituent materials of the bag.

2. Chemical Analysis

2.1 Fourier Transform Infrared Spectroscopy (FTIR): Analysis of the materials to determine the chemical composition of the pigments used in the canvas and the other components of the bag.

3. Documentary Analysis

3.1 Receipt Analysis: Verification of the authenticity of the provided receipt, including the comparison of details with the database of transactions recorded by the brand.

3.2 Consultation with the Brand: Communication with brand representatives to confirm the authenticity of the bag. The contacted representatives are Mr. Luigi Rossi (Gucci) and Ms. Claire Leblanc (Balenciaga).

Results

  1. Physical Examination:
    • The visual analysis revealed that the bag presents all the characteristics of authentic bags from this series.
    • The microscopy results confirmed that the materials used are of high quality and correspond to those used in authentic productions.
  2. Chemical Analysis:
    • The FTIR analyses revealed that the chemical composition of the materials is consistent with that of authentic bags from this brand.
  3. Documentary Analysis:
    • The receipt analysis confirmed that the purchase details match the brand’s records.
    • The representatives from Gucci and Balenciaga confirmed the authenticity of the bag and its origin.

Conclusion

Following a meticulous and comprehensive expertise process, we can confirm without any doubt that the Gucci X Balenciaga Hourglass Hacker Aria Supreme canvas bag with GG logo is authentic. This conclusion is based on a series of scientific tests and consultations with representatives of the concerned brands.

Summary

This report details the comprehensive and rigorous analysis conducted to evaluate the quality of the fabric used in the manufacturing of the Gucci X Balenciaga Hourglass Hacker Aria Supreme bag. A sample of the fabric was taken from the bag to conduct a series of scientific tests. Here are the methods used and the results obtained. The authentication of fabric quality in luxury items is a central pillar in determining their authenticity. In this regard, we conducted a series of tests to assess the resistance and durability of the fabric used in the crafting of the bag in question.

Methods and Results

1. Tensile Strength Test

Procedure: A sample of the fabric was mounted on a tensile machine to measure its tensile strength resistance.

Results:

  • Maximum force endured: 500 N
  • Elongation at break: 20%

Conclusion: The results indicate that the fabric demonstrates excellent tensile strength, characteristic of high-quality materials used by luxury brands.

2. Abrasion Resistance Test

Procedure: The test was conducted using a Martindale abrasion machine to evaluate the fabric’s resistance to repeated wear.

Results:

  • Cycles until first visible wear: 50,000 cycles
  • Cycles until failure: 100,000 cycles

Conclusion: The fabric showed exceptional resistance to abrasion, showcasing its durability and ability to maintain its integrity even after prolonged use.

3. Flexural Resistance Test

Procedure: The test was conducted by repetitively folding the fabric sample on a specific machine to evaluate its flexural resistance.

Results:

  • Cycles until first crack: 30,000 cycles
  • Cycles until failure: 60,000 cycles

Conclusion: The fabric withstood a high number of flexural cycles before showing signs of cracking, indicating its good flexural resistance and long-term durability.

General Conclusion

The tests conducted on the fabric sample taken from the Gucci X Balenciaga Hourglass Hacker Aria Supreme bag indicate that the fabric is of high quality, demonstrating excellent resistance to tensile forces, abrasion, and flexure. These results confirm the authenticity and superior quality of the fabric used in the manufacturing of this bag.
