3.77 Ct. Ruby from Mozambique

This transparent 3.77 carat oval ruby from Mozambique presents a purplish red hue with vivid color intensity, measured at 10.93 by 8.23 by 4.70 millimeters. The stone has been fashioned in a mixed brilliant cut that balances pavilion depth with a faceted crown for controlled brilliance and light return, and it shows an excellent polish across its faceted surfaces. Clarity is graded as slightly included when evaluated at eye level, with natural internal features that are consistent with rubies of this origin and visible only upon focused inspection. The specimen has been heat treated, a widely accepted enhancement that improves color and clarity, and it remains a transparent gem with uniform saturation and pleasing tone. The overall finish and proportions make it suitable as a prominent center stone in a variety of fine jewelry settings, offering a reliable combination of presence and wearability.

When considering complementary gemstones for a custom piece, this purplish red tone pairs effectively with near colorless diamonds to emphasize saturation and add contrast through scintillation and brilliance. A narrow halo or tapered shoulder of round brilliant diamonds in white gold or platinum will increase perceived size and introduce crisp white sparkle, while maintaining a classical aesthetic. For a warmer palette, small rose cut or oval sapphires in soft pink or padparadscha tones can create a harmonious trio, enhancing the ruby color without overpowering it. For a bolder contrast, deep green emeralds set as side stones offer a traditional complementary pairing that highlights the ruby color through color opposition, though careful selection of emerald clarity and size is advised to maintain balance with the ruby. Metal choice will influence the presentation, with 18 karat yellow gold amplifying warmth, and platinum or 18 karat white gold preserving the stone s vivid appearance alongside white accents. For bespoke designs, a low profile bezel or partial bezel can protect the girdle while allowing light to interact with the mixed brilliant cut, and precision prong settings will maximize visible surface area for greater impact. The Natural Ruby Company can provide additional matching gemstones and technical guidance for mounting this 3.77 carat Mozambique ruby in a custom ring, pendant, or pair of earrings, ensuring the final piece respects the stone s optical attributes and long term durability.
