I put this stone (along with others) in a storage shelter 25 years ago when I moved from L.A. to New Mexico. I forgot about it in the chaos of moving. What a treat to rediscover this gem. Back then, it was certified by GIA but it was so long ago there records no longer contain the cert. It's authentic as stated.

Green sapphire—what buyers look for

Species/Hardness: Corundum (Mohs 9). Tough enough for daily-wear rings.

Color chemistry: Greens come mainly from iron (and sometimes vanadium/chromium). Hues range from yellow-green and olive to blue-green; the purer, richer greens bring the strongest prices.

Pleochroism: Different viewing angles can show yellow-green, blue-green, or gray-green—cutting orientation matters.

Cut: Bright, symmetrical cuts with minimal “extinction” (dark patches) and no windowing are preferred.

Clarity: Eye-clean stones price higher. Typical inclusions are feathers, crystals, or (if unheated) fine rutile “silk.”

Treatment: Standard heat is common and acceptable with a modest discount. No-heat carries a premium. Beryllium diffusion (rare in greens but possible) or fracture filling should be disclosed and reduces value.

Origin/report: A report from GIA/AGL/GRS/Lotus confirming natural sapphire and treatment status increases buyer confidence and price.

Your stone (from the photos)

Shape/Cut: Oval mixed cut with a moderately high crown; checkerboard look on the pavilion/upper facets in some frames.

Color: Olive to forest green with warm yellow flashes; medium-dark tone. Attractive, earthy color that’s popular now, but not a pure vivid green.

Brilliance: Looks lively around the rim with some extinction toward the center in certain angles; not a full window.

Clarity: Appears slightly included on close inspection (a few internal features/light reflecting planes), likely still eye-clean at arm’s length.

Overall impression: A solid, wearable green sapphire with good color and a respectable cut. If the color shifts bluer in daylight, that helps.

Pricing (retail asking ranges)

Pricing depends most on color purity/saturation, clarity, cut, treatment, and carat weight. For oval green sapphires:

Commercial/olive or gray-green, included, average cut: $150–$350/ct

Good quality (pleasing olive/forest green, eye-clean, decent make): $350–$700/ct

Fine (purer rich green, bright, eye-clean, good make): $700–$1,500/ct

Exceptional (vivid green, minimal extinction, no-heat with report): $1,500–$3,000+/ct

Where yours likely sits (from photos): Good category ~$350–$600 per carat.

If your stone is ~2.0 ct, think $700–$1,200 total.

If it’s ~3.0 ct, think $1,050–$1,800 total.
(If a lab confirms no heat and the stone looks brighter outdoors, nudge to the upper end.)

How to nudge value upward

Daylight photos/video on a neutral gray background (avoid green backdrops that reflect).

List exact millimeter size and whether it’s eye-clean at 25–30 cm viewing.

Note any color shift (olive indoors greener outdoors); buyers of green sapphires often look for that.
