HPHT-treated diamonds offer excellent value, as they are of high color and clarity but are less expensive than untreated stones.
Are CVD diamonds worth it?
CVD, or Chemical Vapor Deposition, diamonds. That's because CVD isn't an acronym that those outside of the diamond industry generally encounters. And that's unfortunate, because, for anyone interested in diamonds, their environmental and social impact, and their cost, CVD diamonds are definitely worth looking into.
Is CVD diamond fake?
Are CVD Diamonds Real diamonds? Yes, CVD diamonds are real diamonds. Although grown in a lab, CVD diamonds are gem-quality diamonds that have the same elemental structure and the same physical, chemical and optical properties as their natural counterparts.
Which lab grown diamond process is better?
Lab-grown diamonds, whether created via the HPHT or CVD method are far superior and more affordable than anything we will ever get out of the earth. Not to mention they are the most ethical option and are truly conflict free. The majority of lab grown diamonds sold at MiaDonna are created using the CVD method.
Are HPHT diamonds good?
HPHT diamonds are a great option because they are natural diamonds, come GIA certified, and allow you to enjoy a bigger, more beautiful diamond at a fraction of the cost. What Is The Difference Between An HPHT Diamond and Non-HPHT Diamond? Non-HPHT diamonds and HPHT diamonds are both real, natural diamonds.
Which is better HPHT or CVD diamonds?
The HPHT process is very costly, given the energy and equipment required, and produces diamonds with mainly yellowish or brownish yellow colors. The CVD method is much less costly because it works at moderate temperatures and low pressure, which requires smaller and less expensive equipment.
Are HPHT diamonds cheaper?
HPHT diamonds are less expensive than their natural counterparts and develop a significantly better color after undergoing this process. Companies purchase cheaper, less desirable diamonds, put them through the HPHT process, and sell the resulting (and better looking) gems at a much higher price.
Does GIA certify HPHT diamonds?
Do HPHT Diamonds Come with a GIA certificate? Yes! The Gemological Institute of America—the most respected authority in diamond grading--recognizes HPHT diamonds, and considers the process non-invasive and permanent.
What is the difference between HPHT and CVD diamond?
The main difference between HPHT vs CVD diamonds is the way they grow or their morphology. HPHT diamonds grow in cuboctahedron shape and have 14 growth directions, while CVD diamonds grow cubic and have 1 growth direction. These growth patterns are also the main way to tell mined and synthetic diamonds apart.
Does Hpht pass diamond tester?
This does not mean that HPHT diamonds are not real diamonds, it just indicates that some diamonds formed by this process consist of excess impurities. However, if an HPHT diamond has minimal to no impurities present in its composition, those diamonds will easily pass the test.
What is Hpht in diamond?
What Are HPHT Diamonds? At London Gold, our HPHT diamonds are real, natural diamonds that have undergone a High Pressure High Temperature process to enhance their color. The treatment turns a naturally brownish diamond into a whiter, more beautiful diamond.
