In the diamond industry, size is not the sole determinant of a stone's value. In fact, two diamonds of the same weight can vary significantly in value if they differ in cut, clarity, color, and other optical characteristics.
The difference between high-standard and low-standard diamonds is not just in price, but also directly affects: sparkle, durability, asset value, and future liquidity.
Therefore, when choosing diamonds, quality standards must be prioritized. So, how do high-standard diamonds truly differ from ordinary diamonds, and why is this factor so important? Let's find out with Jemmia Diamond through the article below.
What are high-standard diamonds?
High-standard diamonds are diamonds that achieve high quality grades within the GIA's (Gemological Institute of America) 4Cs grading system, and also possess crystal structures, cut proportions, and inclusion characteristics that do not affect the stone's light performance and durability.
In practice, a diamond is usually considered to be of high quality when it simultaneously meets the following standards:
- Color: from grade I upwards.
- Clarity: from VS2 upwards.
- Cut: Triple Excellent, including Excellent Cut, Excellent Symmetry, and Excellent Polish.
- Fluorescence: from None to Medium.
In addition to the 4Cs parameters, the evaluation of high-quality diamonds also considers the Key to Symbols in the GIA report to determine the nature and location of internal inclusions. High-standard diamonds typically do not have large or prominent features such as:
- Indented Natural: A natural indentation on the diamond's surface
- Cavity: A small pit on the surface, formed when an internal crystal is lost or separated during cutting and polishing.
- Chip: A small nick on the surface, often appearing at the diamond's edge.
- Twinning Wisp: An internal inclusion, appearing as a small, faint white line, often extending through the diamond.
- Bearding: Fractures that run along the diamond's girdle and extend into the interior of the diamond.
When these features appear in large sizes or in easily visible locations, they often cause the diamond to no longer be classified as high quality, even if the 4Cs parameters are still good.
Therefore, in the diamond industry, the concept of "high-standard diamond" is not based on a single indicator but is a combination of many quality factors, from the 4Cs to the internal structure of inclusions within the stone. Stones that meet these criteria often possess optimal light performance, high durability, and more stable market value.
Many high-end diamond brands on the market apply more stringent selection processes, conducting in-depth screening of cut, clarity, crystal structure, and factors affecting the diamond's light reflection, durability, and long-term value.
High-standard diamonds are diamonds that achieve superior quality in the 4Cs.
Why buy high-standard diamonds?
1. Lasting Brilliance Through Time
High-standard diamonds typically possess high color grades, good clarity, and few inclusions that affect the crystal structure. These factors help the diamond maximize its dispersion and reflection of light, creating its characteristic Brilliance, Fire, and Scintillation.
Furthermore, diamonds that meet high standards usually do not have large inclusions or blemishes that can affect the durability and integrity of the stone. As a result, the diamond can maintain its radiant beauty for many years of use without diminishing its aesthetic value.
High-quality diamonds possess lasting brilliance through time.
2. Natural Scarcity
In the diamond industry, scarcity is a crucial factor determining value. A high-standard diamond is not only rare because it is a natural diamond, but also because it must simultaneously achieve a high color grade, good clarity, and a stable crystal structure.
During the billions of years of crystallization deep within the earth, even the presence of nitrogen or other impurities can alter the diamond's color and clarity. Therefore, diamonds that are nearly colorless and have few inclusions appear in very low proportions in nature, making them exceptionally rare and highly valuable.
3. High Market Liquidity
High-standard diamonds generally have good liquidity due to their clear quality and international market recognition. Diamonds with GIA certificates, transparent 4Cs specifications, and clear origins are easily valued and traded globally.
Moreover, as the supply of natural diamonds becomes increasingly limited, diamonds with beautiful colors, high clarity, and excellent cuts are always in demand. In some cases, exceptionally rare diamonds even have the potential to increase in value over time.
High-quality diamonds maintain their value and have good liquidity in the international market.
4. Sustainable Value and Heirloom Potential
More than just a piece of jewelry, a high-standard diamond is considered a durable asset that holds its value over time. With near-absolute durability and timeless beauty, diamonds can be passed down through generations as family heirlooms.
Consequently, many people choose high-standard diamonds to mark significant life milestones and view them as assets that can be passed on to future generations.
High-standard diamonds are chosen to mark important milestones in life.
Risks of Buying Low-Standard Diamonds
Many first-time diamond buyers are often attracted by lower prices. However, diamonds that do not meet quality standards can carry significant risks related to the stone's beauty, durability, and long-term value, including:
Value depreciation immediately after purchase: Diamonds with low color grades, poor clarity, or suboptimal cuts are not highly valued by the market, leading to a sharp loss in value compared to high-standard stones, sometimes by 30–50% of the value.
Low liquidity: When a diamond does not meet high standards for Color, Clarity, Cut, and Key to Symbols characteristics, its scarcity in the market decreases, making future valuation and resale more difficult.
Unsustainable aesthetic value and durability: Inclusions or suboptimal cuts can reduce the diamond's clarity, brilliance, and sparkle, and in some cases, can also affect the stone's structure and durability over time.
Therefore, choosing a diamond is not just about selecting size, but about choosing the right standard. It is the standards for color, clarity, cut, and Key to Symbols that determine whether a diamond is merely a piece of jewelry or truly an asset that can hold long-term value.
Why does Jemmia Diamond only select 2% of high-quality diamonds?
In reality, only a small percentage of diamonds meet all the criteria for cut, color, clarity, and crystal structure. Jemmia Diamond applies a stringent selection process according to international standards, where only about 2% of the highest quality diamonds are selected for distribution.
Jemmia's stringent selection criteria for premium GIA natural diamonds:
| Standard | GIA Diamonds over 3.6mm | Small diamonds |
| Color | From grade I upwards | From grade H upwards |
| Fluorescence | From None to Medium | From None to Medium |
| Cut | Triple Excellent Cut (Ex Cut, Ex Symmetry, Ex Polish) | Very Good or higher |
| Clarity | From VS2 upwards | From VS2 upwards |
Jemmia diamonds are specifically free from inclusions that affect durability, natural structure, and the diamond's value (Indented natural, Chip, Cavity, Twinning Wisp, Bearding).
At Jemmia Diamond, quality standards are further reinforced by transparency in origin, a modern inspection system, and professional, standardized consultation.
- Transparency of Origin and Full Legal Compliance: Each diamond at Jemmia comes with a GIA certificate, import invoice, and ownership contract, ensuring clear origin and transparent legal value.
- GIA Standard Inspection System: Jemmia pioneers the use of inspection equipment such as GIA ID100, GIA Match iD, and Diamond Dock, which accurately verify the characteristics and natural origin of each diamond.
- International Standards Combined with Exquisite Vietnamese Design: Diamonds meeting international standards are crafted with sophisticated jewelry techniques, enhancing the beauty and aesthetic value of high-end jewelry.
- Transparency in Professional Consultation: Each diamond is clearly explained in terms of its 4Cs, standards, and value, helping customers accurately understand what they own.
Thanks to the rigorous selection and inspection process, high-standard diamonds not only offer superior sparkle but also ensure stable asset value, transparency, and market liquidity.
Therefore, when choosing a diamond, it is advisable to prioritize stones that meet high quality standards from the outset to ensure long-term value.
