I purchased the loose stone with the intention of setting it in my own design and never got around to doing it. I am in the process of moving now and would like to see it find a new home. GRS certified the color as "vivid blue (GRS-type 'royal blue')", a designation GRS assigns only to sapphires that meet their strict royal blue color criteria. This stone is uber transparent, no heat, natural Sri Lanka certified. 7.85mm x 5.17mm x 4.48mm total weight 1.63ct. Perfect stone for an engagement ring or a halo setting. Happy to send videos and pics-contact me at steph.doyle717 at gmail.com Will invoice using paypal g&s and ship fedex or UPS only.

For sale is an absolutely stunning Australian pipe opal. It measures roughly 17 x 11mm and has no fractures or surface inclusions. It has never been set. It has was looks like a landscape deep inside, otherwise it is crystal clear. The photos were taken in natural lighting on an overcast day. I’ve collected opals for several years and this is honestly the prettiest one I have. Sadly, it has just been sitting in a drawer, so it’s time she finds a new home. Similar opals start at around $850. Sorry, no returns.
