Affordable & Ethical HPHT Lab Diamonds - Prices, Quality & Buying Tips

An Introduction to HPHT Diamonds

Lab grown diamonds produced through the High Pressure High Temperature (HPHT) method have become increasingly popular in recent years. HPHT diamonds are identical to mined diamonds in terms of physical, chemical, and optical properties. However, they are available at lower price points, making them an attractive alternative for budget-conscious diamond buyers.

In this article, we will provide an overview of HPHT diamonds, including how they are made, their characteristics, and factors that affect their pricing. Whether you are in the market for an engagement ring or simply want to learn more about lab created diamonds, read on to find out if HPHT diamonds may be the right choice for you.

The HPHT Diamond Creation Process

HPHT diamonds are produced in specialized laboratory equipment under conditions that replicate those found deep within the earth. Pressures of over 1.5 million pounds per square inch and temperatures of over 2200°C are required to convert carbon into diamond crystals.

The process begins with a feedstock of graphite and a diamond seed crystal. The graphite is placed into a hydraulic press where the extreme heat and pressure cause the graphite to dissolve into a molten metal solvent. Next, the metal solvent is slowly cooled, allowing carbon atoms to attach to the diamond seed crystal in an organized lattice structure. This produces the sparkling lab grown diamond.

It can take several weeks for a gem quality HPHT diamond to form. The entire process is carefully controlled to create optimal crystal growth. HPHT diamond manufacturers continue to refine their processes to improve diamond quality and production efficiency.

Characteristics of HPHT Diamonds

Diamonds produced through the HPHT method have the same optical, chemical, and physical properties as natural diamonds. They test as Type IIa diamonds, the most chemically pure type of diamond.

HPHT diamonds are rated on the same 4Cs grading scale as mined diamonds - cut, color, clarity, and carat weight. They come in colorless (D-F) and near-colorless (G-J) grades with high clarity ratings. Well-cut oval, round, princess, cushion, and other shapes can be found.

One difference is that HPHT diamonds will have minor blemishes referred to as ‘tattoos’ that are not found in natural diamonds. However, these microscopic markings do not affect the overall appearance or durability of the diamond.

HPHT Diamond Pricing

HPHT diamonds are typically 30-40% less expensive than comparable natural diamonds. For example, a 1 carat HPHT diamond SI1 clarity, G color may retail for around $2,500 while a similar mined diamond would cost closer to $4,000.

Several factors impact HPHT diamond pricing:

• Production costs - HPHT equipment represents a major upfront investment for growers. Efficiency improvements help lower long term overhead costs.
• Economies of scale - Larger HPHT manufacturers benefit from higher production volumes and bulk discounts on equipment, reducing per carat costs.
• Quality - Diamonds with better cut, color, and clarity grades understandably command higher prices.
• Branding - Diamonds sold by retailers with luxury branding and marketing tend to have markup premiums.

However, even when accounting for these factors, HPHT diamond prices remain attractively discounted compared to mined diamond prices at retail. Many diamond experts believe there is room for HPHT diamond prices to increase while still providing exceptional value.

Should You Consider an HPHT Diamond?

For shoppers open to lab grown diamonds, HPHT diamonds represent an affordable option. Here are some of the potential benefits of choosing an HPHT diamond:

• Lower prices than natural diamonds with identical appearance.
• Ethically produced without environmental impact or labor exploitation concerns.
• Customizable with your choice of diamond cut and shape.
• Highest diamond color grades (D-F) rarely found in nature.

The main downside is the lack of resale value, since HPHT diamonds do not come with a grading report from GIA or other gem labs. However, those buying diamonds for personal jewelry purposes often find the discount worthwhile.

Finding Quality HPHT Diamonds

For the best experience purchasing an HPHT diamond, it is important to find a reputable retailer. Here are a few tips:

• Look for retailers that provide detailed diamond inspection reports.
• Ask about the HPHT manufacturer and their production capabilities.
• Review real customer photos and testimonials.
• Ensure fair pricing - extreme low prices may signal poor quality.
• Purchase from retailers that stand behind their products with warranties.

A bit of research goes a long way. The HPHT diamond market offers outstanding diamonds at accessible price points. But focus on quality, transparency, and customer service when shopping to get the most for your investment.

HPHT Diamonds - Frequently Asked Questions

Are HPHT diamonds real diamonds?

Yes, HPHT diamonds have the same physical, chemical, and optical characteristics as natural diamonds. They are not simulants or artificial substitutes - HPHT diamonds are real diamonds grown in a lab instead of the earth.

Do HPHT diamonds last forever?

As authentic diamonds, HPHT diamonds are one of the hardest materials on earth and will last forever with proper care. Their durability and longevity are equal to natural diamonds.

Can you tell the difference between HPHT and mined diamonds?

There is no visible difference between HPHT and natural diamonds. Even under magnification, only trained gemologists can identify HPHT diamonds through very minor impurities. To the naked eye, they look identical.

Are HPHT diamonds eco-friendly?

Yes, lab grown HPHT diamonds have environmental advantages over mined diamonds. Their production has minimal ecological impact, using less land, energy, and water than diamond mining.

Do HPHT diamonds appreciate in value?

HPHT diamonds are unlikely to appreciate significantly, so should not be purchased as an investment. However, their lower upfront cost means you get more diamond for your money.

Where can I buy HPHT diamonds?

Many online jewelry retailers now sell HPHT diamonds. Reputable dealers will provide inspection documentation and access to view 360o videos and real customer photos of the diamond inventory.
