1.58 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This 1.58 carat round blue sapphire from Ceylon Sri Lanka presents a transparent body tone with vivid color intensity and an excellent polish. The gem measures 6.69 x 6.37 x 5.08 mm and has been fashioned in a mixed brilliant cut to balance table brilliance and crown dispersion. Clarity is graded as very slightly included when evaluated at eye level, and the stone has been heat treated in keeping with common industry practice to enhance color uniformity. Photographs and measurements are provided by The Natural Sapphire Company to document the gem proportions and visual character, and the sapphire exhibits the rich cornflower to royal blue hues often associated with quality Ceylon material.

For a custom setting this sapphire performs exceptionally well as a single center stone or as part of a three stone composition, and its vivid blue is complemented by white diamond melee set in a fine halo or pavé to maximize perceived size and scintillation. A platinum or 18k white gold surround will emphasize the cool blue, while 18k yellow gold will add a warmer contrast that brings out the gem secondary tones, and a rose gold accent can create a contemporary juxtaposition with a subtle pink warmth. Side stones that work well include small round brilliant diamonds for sparkle and clarity contrast, tapered baguette diamonds for clean geometric lines, or paired light blue sapphires for a tonal graduated effect. For a bolder palette consider pairing with warm colored sapphires or a single baguette emerald to introduce contrast, and for a refined engagement style the sapphire in a low profile bezel or classic four prong head will retain durability while showcasing the mixed brilliant cut. The Natural Sapphire Company can advise on precise proportions for settings to accommodate the 6.69 x 6.37 x 5.08 mm dimensions and to ensure the chosen metal and accent stones harmonize with the sapphire clarity and vivid color.
