0.62 ct Natural Unheated Yellow Sapphire – Oval Cut | AGCL Certified | Sri Lanka (Ceylon)

This 0.62 ct natural yellow sapphire is cut oval and completely unheated, documented on AGCL Report #M263115. The stone's warm, luminous golden yellow color comes from trace iron in the corundum crystal, entirely without thermal modification — a well-priced entry point into natural unheated yellow sapphire, suited for accent work, a custom setting, or a Jyotish commission.

Rarity Analysis

A few factors work together on this stone:

• Color: Natural golden yellow from trace iron, unmodified by heat.
• Size: 0.62 ct sits above the sub-half-carat range where unheated stones are hardest to find individually certified, without reaching the premium pricing of larger unheated yellow sapphires.
• Treatment: AGCL Report #M263115 confirms no indication of heating.
• Cut: The oval shape maximizes face-up color display relative to carat weight.
• Documentation: Independently lab-certified with weight, dimensions, and treatment status confirmed.
• Combined effect: unheated, certified yellow sapphire at this weight and price point is not the norm — most yellow sapphire in this range on the broader market is heat-treated.

Buying Guidance

A few practical points to weigh before purchasing this specific stone:

• Setting fit: at 5.94 x 4.00 mm, confirm this oval fits your intended setting's stone seat before ordering.
• Jyotish buyers: if using for Vedic astrological purposes, confirm 0.62 ct meets your astrologer's recommended minimum weight.
• Compare to heated alternatives: heated yellow sapphires of similar size are more common and typically less expensive; the premium here reflects unheated status.
• Certification: keep the AGCL report with the stone as your primary treatment record.
• Use the Try Before You Buy option if you would like to see the stone in hand before finalizing the purchase.
