Type IIa diamonds allow deeper UV light to pass through and thus its UV light absorption ability is low. This difference in the light absorption is significant enough to aid in differentiating between colorless Type Ia and Type IIa diamonds.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"text-decoration: underline;\"\u003eFeatures:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAdvanced technology that measures a diamond’s UV light transmittance ability\u003c\/li\u003e\n\u003cli\u003e2 colour coded (blue\/red) indicator light bars to give a low or high reading of UV light absorption with blue light indicating Natural Diamond and red light indicating Type IIa Diamond\u003c\/li\u003e\n\u003cli\u003eInstantaneous clear results within 2 seconds\u003c\/li\u003e\n\u003cli\u003eBlue light to illuminate the testing pad\u003c\/li\u003e\n\u003cli\u003eA 5mm metal bar to conveniently raise the test probe for successive testing on loose stones\u003c\/li\u003e\n\u003cli\u003eTest button will blink in red to alert if the device is unable to detect any stones on the photo-detector\u003c\/li\u003e\n\u003cli\u003eAuto shutdown of interior LED light source for safe testing when lid of device is open or when Start Test button is not activated\u003c\/li\u003e\n\u003cli\u003eUSB port for alternative power source and connectivity\u003c\/li\u003e\n\u003cli\u003eExterior base foam padding to ensure non-slip sturdiness and prevent scratches to surfaces\u003c\/li\u003e\n\u003cli\u003eLow battery indicator\u003c\/li\u003e\n\u003cli\u003eEnergy-saving auto power-off of device after 10 minutes without operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cdiv\u003e\u003cspan style=\"text-decoration: underline;\"\u003eBenefits:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eHelp to screen out Type IIa diamonds likely to be laboratory-grown diamonds\u003c\/li\u003e\n\u003cli\u003eTests on diamonds within a range in dimension from 1.5 mm in width and up to 5 mm in height (approx. 0.02 to 10 carat size)\u003c\/li\u003e\n\u003cli\u003eTests on polished diamonds of popular cuts such as brilliant round cut, emerald cut, baguette cut, etc\u003c\/li\u003e\n\u003cli\u003eCan be used on both loose and mounted diamonds (on jewelry with open-back setting)\u003c\/li\u003e\n\u003cli\u003eFor use on colorless diamonds from D Color down to J Color\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cspan style=\"text-decoration: underline;\"\u003eSpecifications:\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan style=\"text-decoration: underline;\"\u003ePower \u0026amp; Battery:\u003c\/span\u003e\n\u003cul\u003e\n\u003cli\u003e4 x AAA alkaline batteries\u003c\/li\u003e\n\u003cli\u003eUSB port to be used with USB cable and appropriate Presidium Universal USB Power Adaptor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cspan style=\"text-decoration: underline;\"\u003eRecommended Operating Conditions:\u003c\/span\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cli\u003eOnly for Colorless Diamonds of:\u003c\/li\u003e\n\u003cli\u003eColor Grade: D Color to J Color\u003c\/li\u003e\n\u003cli\u003eCarat Size: 0.02 carat to \u0026gt;10 carats\u003c\/li\u003e\n\u003cli\u003eCut: For all cuts as long as gemstone has a flat surface\u003c\/li\u003e\n\u003cli\u003eMounted Jewelry: For jewelry with “open-back” setting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cspan style=\"text-decoration: underline;\"\u003eDimensions:\u003c\/span\u003e\n\u003cul\u003e\n\u003cli\u003eLength: 130mm (5.12 inches)\u003c\/li\u003e\n\u003cli\u003eWidth: 100mm (3.94 inches)\u003c\/li\u003e\n\u003cli\u003eHeight: 65mm (2.56 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cspan style=\"text-decoration: underline;\"\u003eWeight:\u003c\/span\u003e\u003cbr\u003e\n\u003cul\u003e\n\u003cli\u003eWeight (without batteries): 210grams (7.40 oz)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Presidium","offers":[{"title":"Default Title","offer_id":59398695059790,"sku":"Presidium SDS II","price":650.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1025\/2940\/1166\/files\/1747726004-73086100.png?v=1775931098","url":"https:\/\/maddisonsofdurham.co.uk\/products\/presidium-synthetic-diamond-screener-2-sds-ii","provider":"Maddisons of Durham","version":"1.0","type":"link"}
