Size & Weight
- All gemstones are measured in millimeters (mm).
- Dimensions are listed as length × width × depth, except for round stones which are measured as diameter × depth.
- Always choose gemstones by size, not by weight!
- Different gem varieties have different densities, so carat weight isn’t a reliable indicator of size.
- Note: 1 ct = 0.2 g
| Treatment | Description |
|---|---|
| Natural | This gemstone has zero treatments—no heat, no irradiation, no filling, no stabilisation. It’s simply mined, cut, and polished. |
| Heated | Heating enhances or develops colour and clarity, commonly seen in Sapphire, Ruby, Tanzanite, Topaz, and Zircon. |
| Dyed | This process adds colouring agents to create a richer, more even colour. Traditionally associated with Agate and still used today for certain Onyx and Agate stones. |
| Irradiated | Radiation treatment modifies light absorption, transforming clear stones like Topaz into blue varieties. |
| Coated | A thin metallic film is added to produce the iridescent look found in Mystic or Azotic quartz. |
| Smoked | Foil-wrapping and gentle heating allow smoke to enter the opal, darkening its body colour and boosting play-of-colour. Common in some Ethiopian Black Opals. |
| Stabilised | Resin or polymer is infused into porous gems to improve hardness, density, and colour—essential for fragile stones like Turquoise. |
| Cultured | Human-assisted pearls grown in freshwater or saltwater molluscs. They grow faster and are more reliable, which keeps them affordable. |

Natural Beauty in Every Stone
No two natural gemstones are perfectly identical. Our Midnight Quartz pieces may show differences in tone, internal characteristics, transparency and natural inclusions, giving every stone its own visual personality.
These natural characteristics add depth to the gemstone and can make each finished jewelry piece feel more personal and exclusive. We carefully select stones that offer an attractive combination of appearance, polish and overall quality.
Precision Craftsmanship from Our Own Manufacturing Unit
We cut and finish our gemstones in our own manufacturing unit, allowing us to maintain close attention throughout the shaping and polishing process. Our experienced artisans have been working with gemstones for around 20 years, bringing extensive practical knowledge to every stage of finishing.
After cutting and polishing, our quality control team carefully checks the stones for finish, surface appearance, shape and overall presentation before they are prepared for delivery.
Authenticity & Professional Quality Control
Our gemstone operations are supported by a team of expert gemologists and experienced artisans who understand gemstone selection, cutting and finishing. Gemstone material is tested through authentic laboratory sources as applicable, helping us maintain reliable quality standards.
