Product & Diamond FAQ

Lab-grown diamonds are real diamonds with same carbon structure and chemical composition. A 'Lab Diamond' is exactly like a Natural Diamond, except instead of mining it from the Earth, they are grown in a lab.

They sparkle the same, have the same types of colour and clarity, and can come in the same sizes and shapes. In fact, they offer excellent value and are more affordable than natural ones of comparable quality and size.

Two important reasons to choose a lab diamond are origin & value. Rest assured that your diamond did not result in the funding of conflict in a war-torn country, nor did it require leaving a mile-wide hole in the ground. Also objectively, diamonds grown above the Earth are more pure than "dirt diamonds", blasted out of the Earth with dynamite and diesel. Compared to diamonds grown in the chaos under the Earth, diamonds grown by mankind have fewer defects and less strain in the crystal structure.

Quite simply, the more pure the diamond, the better, brighter, and whiter the gemstone.

Most of HOQs white lab diamonds receive the highest purity rating of Type IIa whereas less than 2% of mined diamonds receive the coveted IIa purity rating.

Lab diamonds receive grading reports from independent gemological organisations on the 4Cs: Cut, Color, Clarity, and Carat Weight. Just like in mined diamonds, lab diamonds will exhibit variations across the 4Cs and range from poor to superlative quality. Not all lab diamonds are perfect, colorless, and flawless!

The simple answer is that the mined diamond industry, from the industrial miners all the way to retailers, fear the coming disruption of laboratory-grown diamonds.

The oligopoly of diamond mining creates artificial scarcity and continues to stymie the growth of this new age diamond. Part of that effort involves spreading fear, uncertainty, and doubt about lab diamonds.

Lab grown diamonds are created using an advanced technology whereas natural diamonds are mined from under the surface of the earth. Lab diamonds do not incur the expense of mining,
transportation and artificial created scarcity and hence are free from the high mark-ups. Literally diamonds
that don’t cost the earth.

We only offer G+ VVS-VS stones, and our 1ct+ lab diamonds are IGI certified. The gold is 18K and BIS Hallmarked. You always know you’re getting the best.

Well, Quadri in Italian means diamonds (like in a suit of cards); also referring to 4 corners - think quadri-lateral. Hence, House of Quadri indicates house of diamonds. :)
