The two main methods of identifying color-enhanced diamonds are color zoning and spectroscopy. Color zoning can provide an indication of probable color enhancement, but only spectroscopy, a procedure done in a trade lab by a trained gemologist, will give a conclusive answer on the origin of a diamond’s color.
Are all colored diamonds enhanced?
The first thing you need to know about enhanced color diamonds is that they are real, not synthetic diamonds. Typically, enhanced color diamonds start out as nearly colorless diamonds in their raw state. They then undergo a color-enhancement process using irradiation or HPHT (high temperature, high pressure).
What does it mean when a diamond is color enhanced?
Color-enhanced diamonds undergo a high pressure, high temperature (HPHT) process to alter their color. Diamonds with a slight coloring might go through this process to make them appear whiter. Slightly tinted diamonds also may be color enhanced to enrich their color, making them a distinct tone like yellow or pink.
How do they color enhance a diamond?
A process known as HPHT (High Pressure High Temperature) is used to enhance the color of darker diamonds. HPHT recreates the natural diamond forming conditions of the earth and can colorize or whiten the diamond. HPHT is also one of two processes used to grow lab-grown diamonds.
Are color enhanced diamonds bad?
When these stones are polished, little attention is paid to achieving better cut quality because it doesn’t make economic sense to do so. The truth of the matter is that 99.99% of clarity enhanced diamonds are absolutely terrible in terms of cut standards.
Do enhanced diamonds hold their value?
Do Clarity Enhanced Diamonds Hold their Value? Yes, clarity enhanced diamonds like all other diamonds hold their value according to normal price fluctuations of diamonds as well as taking into account current market values and conditions.
Are enhanced blue diamonds valuable?
Overview. Enhanced blue diamonds are natural diamonds that have undergone color enhancement treatments. … Untreated, natural blue diamonds can be found, but they are extremely rare. This scarcity makes them one of the most sought-after and expensive gemstones available today.
Are enhanced diamonds fake?
Are they real or fake? A clarity enhanced diamond is a natural diamond, not an imitation diamond like moissanite or a lab-made diamond-like Gemesis. Untreated diamonds with visible inclusions or blemishes are often used for clarity-enhanced diamonds.
Does GIA certify enhanced diamonds?
Futhermore, GIA doesn’t currently certify clarity enhanced diamonds. EGL certifies these diamonds along with additonal labratories.
How do you know if a diamond has been treated?
Because there is no way to see if a diamond has been treated, it is important to have a diamond grading report from an independent lab like GIA. As part of its grading process, GIA tests all diamonds for treatments; if the diamond is treated, it will be disclosed on the certificate.
What is the rarest color of diamonds?
In diamonds, rarity equals value. With diamonds in the normal range, value is based on the absence of color, because colorless diamonds are the rarest. With fancy color diamonds—the ones outside the normal color range—the rarest and most valuable colors are saturated pinks, blues, and greens.
Can Diamond color change?
It can change its color from olive to a deep yellow hue. This situation occurs when you keep the diamond in the dark for 24 hours or heat it to 200-300 Celsius. … Some diamonds change their tone from stable yellow to green when they are heated.
Are treated diamonds worth less?
A stone that has been treated to improve clarity can cost 20-30% less than an untreated diamond of the same clarity grade. So, if you consider enhanced diamonds, you can get a pretty good deal on a stone with the clarity grade you are looking for.
Do enhanced diamonds last?
You can wear and enjoy a larger diamond every day. Blow everyone away with size and beauty of an incredible diamond. GIA/EGL certified diamonds of “comparable” beauty cost 2-3 times more. Your Clarity Enhancement Treatment is GUARANTEED FOR LIFE!
Can clarity enhanced diamonds break?
A treated or an enhanced diamond will crack or break in these environments. The cost of treated diamonds should be at least 50% less than a natural diamond. Some retail jewelers don’t disclose the fact the diamond has been fracture filled or laser drilled.
Which treatment is permanent and requires no special care?
Laser drilling and HPHT treatments – Both are permanent and require no special care.
