FAQ

What is a diamond solitaire ring? A diamond solitaire ring features a single centre diamond in a minimal setting - two to six prongs or a bezel rim - on a plain or lightly detailed gold band. There are no accent stones, no halo, and no surrounding pavé. The solitaire places all visual focus on the single certified diamond. It is the most widely purchased diamond ring design in the world and the default engagement ring format.
A 0.50ct lab grown diamond solitaire ring with IGI certification in 18KT gold costs ₹35,000–60,000 in India in 2026. A 1ct IGI-certified solitaire in 18KT white gold costs ₹55,000–90,000 - the complete ring including diamond, setting, gold, making charges, and GST. A 2ct certified solitaire ranges from ₹1,20,000–2,00,000. Equivalent mined diamond solitaires at the same certified quality typically cost 2–3x more.
A four-prong solitaire holds the diamond with four metal claws, exposing the maximum crown surface area to light and leaving the most diamond visible above the band. It is the most popular solitaire setting globally. A six-prong solitaire adds two additional prongs for greater structural security for stones above 1.5ct, at the cost of slightly more metal coverage at the girdle. For stones below 1.5ct, the four-prong solitaire is the standard recommendation.
The best solitaire shape depends on what the wearer wants. The oval cut (India’s most popular in 2026) appears larger than its carat weight and elongates the finger. The round brilliant delivers maximum light return with no bow-tie effect and works in any setting. The emerald cut offers step-cut sophistication and architectural depth. The pear, marquise, and heart cuts offer distinctive, immediately recognisable silhouettes. All are available as IGI-certified lab grown diamond solitaires at Lucira.
Cut grade is the most critical factor in a solitaire ring. With no surrounding accent stones to add brilliance, the entire ring’s visual performance depends on how well the centre diamond returns light. An Excellent or Very Good IGI cut grade is the minimum standard for any solitaire ring. Colour and clarity matter, but a well-cut diamond at G colour will outperform a poorly-cut diamond at D colour in daily wear light conditions.
A bezel solitaire ring holds the diamond in a continuous rim of metal that encircles the full girdle of the stone, rather than using prongs. The bezel is the most protective solitaire setting: no prong edges to snag on fabric, full girdle support, and no risk of stone loss from prong failure over time. It produces a clean, modern aesthetic with a defined metal outline around the diamond. Recommended for active lifestyles and buyers who prefer a contemporary, architectural ring profile.
Yes. A lab grown diamond solitaire ring is a real diamond ring. Lab grown diamonds are chemically, physically, and optically identical to mined diamonds. They are graded by IGI and SGL using the same 4Cs framework as mined diamonds and score 10 on the Mohs hardness scale. The only difference between a lab grown and mined diamond solitaire is the origin of the diamond. The certification is the same. The setting is the same BIS hallmarked gold. The ring on the finger is indistinguishable.
