0.50 Carat Lab Grown Round Compass Solitaire Ring 14K Gold

THE STONE(S):

The center stone group consists of 1 round brilliant lab grown diamond weighing exactly 0.50 carats. This stone is graded with an E-F color profile, representing the colorless tier, and a VS clarity rating ensuring an eye-clean facet presentation free of structural inclusions under standard viewing conditions. The stone features an Ideal cut grade with 57 to 58 precisely angled facets, conforming to an optimal table range of 54–57% and a depth range of 59–62.5%. This specific geometric blueprint establishes a hearts and arrows light-return pattern. The primary certification signal is provided by an independent IGI (International Gemological Institute) laboratory report verifying all 4C parameters.

THE SETTING:

The architecture of this piece relies on a specialized 4-prong compass claw configuration. Unlike traditional corner prongs, these four claws grip the stone girdle at the cardinal positions—12, 3, 6, and 9 o’clock relative to the finger profile. This configuration reduces the metal mass visible at the traditional diagonal axes, altering the visual boundaries of the round silhouette. The center stone is elevated by an open gallery basket supported by a low-profile white metal under-rail. This design leaves the upper and lower pavilion facets entirely exposed to lateral light injection, boosting the internal refraction index. The setting is seamlessly integrated onto a wide tapered dome shank that widens mechanically at the shoulders to anchor the crown assembly.

METALS AND FINISH:

The default alloy utilized is solid 14K yellow gold (585 purity, consisting of 58.5% pure elemental gold balanced with structural metals for daily wear durability). The ring can be manufactured across all three primary gold tones: warm yellow, white (finished with rhodium electroplating for a high-reflection surface), and rose gold. For alternative performance requirements, the piece is available in 18K gold (750 purity, offering a richer gold saturation), 10K gold (417 purity, maximizing scratch resistance for highly active lifestyles), and Platinum 950 (95% elemental platinum, providing a dense, naturally hypoallergenic structural frame that requires no rhodium plating). The standard finish applied is a uniform high polish across all exposed metal surfaces.

CUSTOMISATION AND ORIGIN:

Full engineering customization is supported for this design. The center stone can be scaled using standard carat tiers: 0.25ct, 0.50ct, 0.75ct, 1.00ct, 1.25ct, 1.50ct, 2.00ct, 2.50ct, and 3.00ct+. The available specification tier covers a D-I color range and a VVS1-VS2 clarity range to match target budgets.
