FAQ | Buvea Jewels - Your Questions Answered

Lab-grown diamonds at Buvea Jewels are real diamonds created in advanced CVD and HPHT laboratories. They have the same physical, chemical and optical properties as mined diamonds, offering the same sparkle, durability and clarity in a modern, technology-driven way.

Yes. Lab-grown diamonds used by Buvea Jewels are 100% real diamonds, not simulants like cubic zirconia or moissanite. They share the same diamond crystal structure, hardness and brilliance as mined diamonds and are ideal for engagement rings and fine jewellery.

Buvea Jewels sources diamonds grown using CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) processes. These technologies replicate the conditions inside the earth, allowing carbon atoms to form real diamonds that are later cut, polished and set into jewellery.

To the naked eye, a lab-grown diamond and a natural diamond look the same. A well-cut lab-grown diamond from Buvea Jewels has comparable brilliance, fire and sparkle to a mined diamond of the same grade. Specialised laboratory equipment is required to tell the origin apart.

Yes. Lab-grown diamonds avoid large-scale mining and reduce land disruption and associated social impact. At Buvea Jewels, we focus on conflict-free, responsibly grown diamonds, making our lab-grown diamond jewellery a more ethical and lower-impact choice for customers.

Yes. Depending on size and category, lab-grown diamonds from Buvea Jewels are certified by recognised laboratories such as IGI and IDT. Larger centre stones are supplied with individual grading reports showing cut, colour, clarity and carat weight.

Buvea Jewels typically uses high-grade lab-grown diamonds in the D–F colour range and VVS clarity range, with excellent or very good cuts. This combination provides a bright, clean and consistent appearance across our lab-grown diamond jewellery collections.

Yes. Lab-grown diamonds from Buvea Jewels are real diamonds and pass standard diamond testers that measure thermal or electrical conductivity. They behave like mined diamonds in these tests because they share the same physical properties.

Yes. Just like natural diamonds, lab-grown diamonds can have inclusions. At Buvea Jewels, we select stones with high clarity levels so inclusions are minimal and the diamond appears clean and bright in everyday wear.

Buvea Jewels passes this benefit to customers by offering larger or higher-quality lab-grown diamonds at more accessible prices, while maintaining strong craftsmanship and design.
