FACTS ABOUT HPHT DIAMONDS

They Are Authentic As Their Chemical Composition Is Similar To The Mined Diamonds That Are Found In Planet's Crust. Their Physical And Visual Characteristics Are Same As Well.

COST-EFFECTIVE

COST-EFFECTIVE

Lab-grown diamonds are up to 50% cheaper than mined ones, with absolutely no difference in quality and purity. Just imagine a bright, sparkling diamond at practically half the cost!

ECO-FRIENDLY

ECO-FRIENDLY

The diamond-mining process is an extremely energy-intensive and ecologically invasive procedure. That’s why the man-made process of growing diamonds in labs is so eco-friendly.

AS PURE AS MINED DIAMONDS

AS PURE AS MINED DIAMONDS

Lab-grown diamonds are 100% just as pure as mined diamonds, so much so, that it’s difficult to really tell the difference between both without expensive equipment. Our diamonds are certified, with a guarantee of purity.

PROCEDURE OF MAKING HPHT DIAMONDS

HPHT diamonds have gained popularity for several reasons. Major one being a significant decline in production time. Here's the process bifurcated into three steps.

SEEDING
FORMING
CUTTING & POLISHING
SEEDING
FORMING
CUTTING & POLISHING

HPHT diamonds are made using one of three manufacturing processes: the belt press, the cubic press, and the split-sphere (BARS) press. An HPHT diamond begins as a small diamond seed that is placed into carbon.

Using one of the manufacturing processes, the seed is exposed to high temperature and intense pressure into which a small diamond seed encased in carbon is left until it's formed a full-sized diamond.

The pure carbon melts and starts to form a diamond around the starter seed. It is then carefully cooled to form a pure carbon diamond. The lab-grown crystal is then extracted and cleaned in preparation for final cutting and polishing.

The comparison

there is literally no difference that can be spotted between an HPHT diamond and a mined diamond, be it the structure, hardness, density, or composition.

YOUR DIAMOND GUIDE

YOUR DIAMOND GUIDE
CUT : We believe the cut is the most important aspect of choosing a diamond. It's basically what determines the proportion, symmetry, and polish of a diamond. The right cut will enhance the sparkle and the scintillation of the diamond. The better the cut, the more likely your diamond is to sparkle bright and look gorgeous!
COLOR : Ironically, the best color for a diamond would be ‘colorless’. The colors range from D (colorless) and go all the way to Z (light yellow). To be honest, the colour difference in diamonds within a colour family is quite subtle to an untrained eye. Nevertheless, they do create a difference in the price and quality of the diamond. Bottom line is, colorless diamonds are the most precious!
CLARITY : When light passes through a diamond, it bounces back, making the diamond sparkle! Some diamonds have imperfections in the form of spots and blemishes. The more imperfections, the more difficult it is for light to pass through, thereby reducing the sparkle. If you’re lost, here’s all you need to remember: Lesser imperfection and inclusions = Better clarity.
CARAT : A carat (not karat or worse, carrot) is measured based on the weight of the diamond. Two diamonds of equal carat will have different prices, depending on the other 3 Cs you go with. It's quite simple. Your ideal carat depends on: How big you want your stone and obviously, your budget.
The GIA 4Cs of diamond quality will help you learn how to buy a diamond. This basic knowledge will not only unlock the mystery of a diamond’s quality, it will also help you understand a diamond’s value and price.
